Sec. 1.482-7 Methods to determine taxable income in connection with a cost sharing arrangement.

(i) Contribution to a CSA by a controlled taxpayer that is not a controlled participant. If a controlled taxpayer that is not a controlled participant contributes to developing a cost shared intangible, as defined in section (j)(1)(i) of this section, it must receive consideration from the controlled participants under the rules of § 1.482-4(f)(4) (Contribution to the value of an intangible owned by another). Such consideration will be treated as an intangible development cost for purposes of paragraph (d) of this section.

(ii) Transfer of interest in a cost shared intangible. If at any time (during the term, or upon or after the termination, of a CSA) a controlled participant transfers an interest in a cost shared intangible to another controlled taxpayer, the controlled participant must receive an arm's length amount of consideration from the transferee under the rules of § § 1.482-4 through 1.482-6 as supplemented by paragraph (f)(4) of this section regarding arm's length consideration for a change in participation. For this purpose, a capability variation described in paragraph (f)(3) of this section is considered to be a controlled transfer of interests in cost shared intangibles.

(iii) Other controlled transactions in connection with a CSA. Controlled transactions between controlled participants that are not PCTs or CSTs and are not described in paragraph (a)(3)(ii) of this section (for example, provision of a cross operating contribution, as defined in paragraph (j)(1)(i) of this section, or make-or-sell rights, as defined in paragraph (c)(4) of this section) require arm's length consideration under the rules of §§ 1.482-1 through 1.482-6, and 1.482-9 as supplemented by paragraph (g)(2)(iv) of this section.

(iv) Controlled transactions in the absence of a CSA. If a controlled transaction is reasonably anticipated to contribute to developing intangibles pursuant to an arrangement that is not a CSA described in paragraph (b)(1) or (5) of this section, whether the results of any such controlled transaction are consistent with an arm's length result must be determined under the applicable rules of the other sections of the regulations under section 482. For example, an arrangement for developing intangibles in which one controlled taxpayer's costs of developing the intangibles significantly exceeds its share of reasonably anticipated benefits from exploiting the developed intangibles would not in substance be a CSA, as described in paragraphs (b)(1)(i) through (iii) of this section or paragraph (b)(5)(i) of this section. In such a case, unless the rules of this section are applicable by reason of paragraph (b)(5) of this section, the arrangement must be analyzed under other applicable sections of regulations under section 482 to determine whether it achieves arm's length results, and if not, to determine any allocations by the Commissioner that are consistent with such other regulations under section 482. See § 1.482-1(b)(2)(ii) (Selection of category of method applicable to transaction) and (iii) (Coordination of methods applicable to certain intangible development arrangements).

(i) CSTs. All controlled participants must commit to, and in fact, engage in cost sharing transactions. In CSTs, the controlled participants make payments to each other (CST Payments) as appropriate, so that in each taxable year each controlled participant's IDC share is in proportion to its respective RAB share.

(ii) PCTs. All controlled participants must commit to, and in fact, engage in platform contributions transactions to the extent that there are platform contributions pursuant to paragraph (c) of this section. In a PCT, each other controlled participant (PCT Payor) is obligated to, and must in fact, make arm's length payments (PCT Payments) to each controlled participant (PCT Payee) that provides a platform contribution. For guidance on determining such arm's length obligation, see paragraph (g) of this section.

(iii) Divisional interests. Each controlled participant must receive a non-overlapping interest in the cost shared intangibles without further obligation to compensate another controlled participant for such interest.

(iv) Examples. The following examples illustrate the principles of this paragraph (b)(1):

Example 1. Company A and Company B, who are members of the same controlled group, execute an agreement to jointly develop vaccine X and own the exclusive rights to commercially exploit vaccine X in their respective territories, which together comprise the whole world. The agreement provides that they will share some, but not all, of the costs for developing Vaccine X in proportion to RAB share. Such agreement is not a CSA because Company A and Company B have not agreed to share all of the IDCs in proportion to their respective RAB shares.

Example 2. Company A and Company B agree to share all the costs of developing Vaccine X. The agreement also provides for employing certain resources and capabilities of Company A in this program including a skilled research team and certain research facilities, and provides for Company B to make payments to Company A in this respect. However, the agreement expressly provides that the program will not employ, and so Company B is expressly relieved of the payments in regard to, certain software developed by Company A as a medical research tool to model certain cellular processes expected to be implicated in the operation of Vaccine X even though such software would reasonably be anticipated to be relevant to developing Vaccine X and, thus, would be a platform contribution. See paragraph (c) of this section. Such agreement is not a CSA because Company A and Company B have not engaged in a necessary PCT for purposes of developing Vaccine X.

Example 3. Companies C and D, who are members of the same controlled group, enter into a CSA. In the first year of the CSA, C and D conduct the intangible development activity, as described in paragraph (d)(1) of this section. The total IDCs in regard to such activity are $3,000,000 of which C and D pay $2,000,000 and $1,000,000, respectively, directly to third parties. As between C and D, however, their CSA specifies that they will share all IDCs in accordance with their RAB shares (as described in paragraph (e)(1) of this section), which are 60% for C and 40% for D. It follows that C should bear $1,800,000 of the total IDCs (60% of total IDCs of $3,000,000) and D should bear $1,200,000 of the total IDCs (40% of total IDCs of $3,000,000). D makes a CST payment to C of $200,000, that is, the amount by which D's share of IDCs in accordance with its RAB share exceeds the amount of IDCs initially borne by D ($1,200,000 - $1,000,000), and which also equals the amount by which the total IDCs initially borne by C exceeds its share of IDCS in accordance with its RAB share ($2,000,000 - $1,800,000). As a result of D's CST payment to C, the IDC shares of C and D are in proportion to their respective RAB shares.

(i) In general. Pursuant to paragraph (b)(1)(iii) of this section, each controlled participant must receive a non-overlapping interest in the cost shared intangibles without further obligation to compensate another controlled participant for such interest. Each controlled participant must be entitled to the perpetual and exclusive right to the profits from transactions of any member of the controlled group that includes the controlled participant with uncontrolled taxpayers to the extent that such profits are attributable to such interest in the cost shared intangibles.

(ii) Territorial based divisional interests. The CSA may divide all interests in cost shared intangibles on a territorial basis as follows. The entire world must be divided into two or more non-overlapping geographic territories. Each controlled participant must receive at least one such territory, and in the aggregate all the participants must receive all such territories. Each controlled participant will be assigned the perpetual and exclusive right to exploit the cost shared intangibles through the use, consumption, or disposition of property or services in its territories. Thus, compensation will be required if other members of the controlled group exploit the cost shared intangibles in such territory.

(iii) Field of use based divisional interests. The CSA may divide all interests in cost shared intangibles on the basis of all uses (whether or not known at the time of the division) to which cost shared intangibles are to be put as follows. All anticipated uses of cost shared intangibles must be identified. Each controlled participant must be assigned at least one such anticipated use, and in the aggregate all the participants must be assigned all such anticipated uses. Each controlled participant will be assigned the perpetual and exclusive right to exploit the cost shared intangibles through the use or uses assigned to it and one controlled participant must be assigned the exclusive and perpetual right to exploit cost shared intangibles through any unanticipated uses.

(iv) Other divisional bases.

(v) Examples. The following examples illustrate the principles of this paragraph (b)(4):

Example 1. Companies P and S, both members of the same controlled group, enter into a CSA to develop product Z. Under the CSA, P receives the interest in product Z in the United States and S receives the interest in product Z in the rest of the world, as described in paragraph (b)(4)(ii) of this section. Both P and S have plants for manufacturing product Z located in their respective geographic territories. However, for commercial reasons, product Z is nevertheless manufactured by P in the United States for sale to customers in certain locations just outside the United States in close proximity to P's U.S. manufacturing plant. Because S owns the territorial rights outside the United States, P must compensate S to ensure that S realizes all the cost shared intangible profits from P's sales of product Z in S's territory. The pricing of such compensation must also ensure that P realizes an appropriate return for its manufacturing efforts. Benefits projected with respect to such sales will be included for purposes of estimating S's, but not P's, RAB share.

Example 2. The facts are the same as in Example 1 except that P and S agree to divide their interest in product Z based on site of manufacturing. P will have exclusive and perpetual rights in product Z manufactured in facilities owned by P. S will have exclusive and perpetual rights to product Z manufactured in facilities owned by S. P and S agree that neither will license manufacturing rights in product Z to any related or unrelated party. Both P and S maintain books and records that allow production at all sites to be verified. Both own facilities that will manufacture product Z and the relative capacities of these sites are known. All facilities are currently operating at near capacity and are expected to continue to operate at near capacity when product Z enters production so that it will not be feasible to shift production between P's and S's facilities. P and S have no plans to build new facilities and the lead time required to plan and build a manufacturing facility precludes the possibility that P or S will build a new facility during the period for which sales of Product Z are expected. Based on these facts, this basis for the division of interests in Product Z is a division described in paragraph (b)(4)(iv) of this section. The basis for the division of interest is unambiguous and clearly defined and its use can be dependably verified. P and S both have non-overlapping, exclusive and perpetual rights in Product Z. The division of interest results in the participant's relative benefits being predictable with reasonable reliability.

Example 3. The facts are the same as in Example 2 except that P's and S's manufacturing facilities are not expected to operate at full capacity when product Z enters production. Production of Product Z can be shifted at any time between sites owned by P and sites owned by S, although neither P nor S intends to shift production as a result of the agreement. The division of interests in Product Z between P and S based on manufacturing site is not a division described in paragraph (b)(4)(iv) of this section because their relative shares of benefits are not predictable with reasonable reliability. The fact that neither P nor S intends to shift production is irrelevant.

(i) Situation in which Commissioner must treat arrangement as a CSA. The Commissioner must apply the rules of this section to an arrangement among controlled taxpayers if the administrative requirements of paragraph (b)(2) of this section are met with respect to such arrangement and the controlled taxpayers reasonably concluded that such arrangement was a CSA meeting the requirements of paragraphs (b)(1), (3), and (4) of this section.

(ii) Situation in which Commissioner may treat arrangement as a CSA. For arrangements among controlled taxpayers not described in paragraph (b)(5)(i) of this section, the Commissioner may apply the provisions of this section if the Commissioner concludes that the administrative requirements of paragraph (b)(2) of this section are met, and, notwithstanding technical failure to meet the substantive requirements of paragraph (b)(1), (3), or (4) of this section, the rules of this section will provide the most reliable measure of an arm's length result. See § 1.482-1(c)(1) (the best method rule). For purposes of applying this paragraph (b)(5)(ii), any such arrangement shall be interpreted by reference to paragraph (k)(1)(iv) of this section.

(iii) Examples. The following examples illustrate the principles of this paragraph (b)(5). In the examples, assume that Companies P and S are both members of the same controlled group.

Example 1. (i) P owns the patent on a formula for a capsulated pain reliever, P-Cap. P reasonably anticipates, pending further research and experimentation, that the P-Cap formula could form the platform for a formula for P-Ves, an effervescent version of P-Cap. P also owns proprietary software that it reasonably anticipates to be critical to the research efforts. P and S execute a contract that purports to be a CSA by which they agree to proportionally share the costs and risks of developing a formula for P-Ves. The agreement reflects the various contractual requirements described in paragraph (k)(1) of this section and P and S comply with the documentation, accounting, and reporting requirements of paragraphs (k)(2) through (4) of this section. Both the patent rights for P-Cap and the software are reasonably anticipated to contribute to the development of P-Ves and therefore are platform contributions for which compensation is due from S as part of PCTs. Though P and S enter into and implement a PCT for the P-Cap patent rights that satisfies the arm's length standard, they fail to enter into a PCT for the software.

(ii) In this case, P and S have substantially complied with the contractual requirements of paragraph (k)(1) of this section and the documentation, accounting, and reporting requirements of paragraphs (k)(2) through (4) of this section and therefore have met the administrative requirements of paragraph (b)(2) of this section. However, because they did not enter into a PCT, as required under paragraphs (b)(1)(ii) and (b)(3) of this section, for the software that was reasonably anticipated to contribute to the development of P-Ves (see paragraph (c) of this section), they cannot reasonably conclude that their arrangement was a CSA. Accordingly, the Commissioner is not required under paragraph (b)(5)(i) of this section to apply the rules of this section to their arrangement.

(iii) Nevertheless, the arrangement between P and S closely resembles a CSA. If the Commissioner concludes that the rules of this section provide the most reliable measure of an arm's length result for such arrangement, then pursuant to paragraph (b)(5)(ii) of this section, the Commissioner may apply the rules of this section and treat P and S as entering into a PCT for the software in accordance with the requirements of paragraph (b)(1)(ii) of this section, and make any appropriate allocations under paragraph (i) of this section. Alternatively, the Commissioner may conclude that the rules of this section do not provide the most reliable measure of an arm's length result. In such case, the arrangement would be analyzed under the methods under other sections of the 482 regulations to determine whether the arrangement reaches an arm's length result.

Example 2. The facts are the same as in Example 1 except that P and S do enter into and implement a PCT for the software as required under this paragraph (b). The Commissioner determines that the PCT Payments for the software were not arm's length; nevertheless, under the facts and circumstances at the time they entered into the CSA and PCTs, P and S reasonably concluded their arrangement to be a CSA. Because P and S have met the requirements of paragraph (b)(2) of this section and reasonably concluded their arrangement is a CSA, pursuant to paragraph (b)(5)(i) of this section, the Commissioner must apply the rules of this section to their arrangement. Accordingly, the Commissioner treats the arrangement as a CSA and makes adjustments to the PCT Payments as appropriate under this section to achieve an arm's length result for the PCT for the software.

Example 3. (i) The facts are the same as in Example 1 except that P and S do enter into a PCT for the software as required under this paragraph (b). The agreement entered into by P and S provides for a fixed consideration of $50 million per year for four years, payable at the end of each year. This agreement satisfies the arm's length standard. However, S actually pays P consideration at the end of each year in the form of four annual royalties equal to two percent of sales. While such royalties at the time of the PCT were expected to be $50 million per year, actual sales during the first year were less than anticipated and the first royalty payment was only $25 million.

(ii) In this case, P and S failed to implement the terms of their agreement. Under these circumstances, P and S could not reasonably conclude that their arrangement was a CSA, as described in paragraph (b)(1) of this section. Accordingly, the Commissioner is not required under paragraph (b)(5)(i) of this section to apply the rules of this section to their arrangement.

(iii) Nevertheless, the arrangement between P and S closely resembles a CSA. If the Commissioner concludes that that the rules of this section provide the most reliable measure of an arm's length result for such arrangement, then pursuant to paragraph (b)(5)(ii) of this section, the Commissioner may apply the rules of this section and make any appropriate allocations under paragraph (i) of this section. Alternatively, the Commissioner may conclude that the rules of this section do not provide the most reliable measure of an arm's length result. In such case, the arrangement would be analyzed under the methods under other sections of the 482 regulations to determine whether the arrangement reaches an arm's length result.

Example 4. (i) The facts are the same as in Example 1 except that P does not own proprietary software and P and S use a method for determining the arm's length amount of the PCT Payment for the P-Cap patent rights different from the method used in Example 1.

(ii) P and S determine that the arm's length amount of the PCT Payments for the P-Cap patent is $10 million. However, the Commissioner determines the best method for determining the arm's length amount of the PCT Payments for the P-Cap patent rights and under such method the arm's length amount is $100 million. To determine this $10 million present value, P and S assumed a useful life of eight years for the platform contribution, because the P-Cap patent rights will expire after eight years. However, the P-Cap patent rights are expected to lead to benefits attributable to exploitation of the cost shared intangibles extending many years beyond the expiration of the P-Cap patent, because use of the P-Cap patent rights will let P and S bring P-Ves to market before the competition, and because P and S expect to apply for additional patents covering P-Ves, which would bar competitors from selling that product for many future years. The assumption by P and S of a useful life for the platform contribution that is less than the anticipated period of exploitation of the cost shared intangibles is contrary to paragraph (g)(2)(ii) of this section, and reduces the reliability of the method used by P and S.

(iii) The method used by P and S employs a declining royalty. The royalty starts at 8% of sales, based on an application of the CUT method in which the purported CUTs all involve licenses to manufacture and sell the current generation of P-Cap, and declines to 0% over eight years, declining by 1% each year. Such make-or-sell rights are fundamentally different from use of the P-Cap patent rights to generate a new product. This difference raises the issue of whether the make-or-sell rights are sufficiently comparable to the rights that are the subject of the PCT Payment. See § 1.482-4(c). While a royalty rate for make-or-sell rights can form the basis for a reliable determination of an arm's length PCT Payment in the CUT-based implementation of the income method described in paragraph (g)(4) of this section, under that method such royalty rate does not decline to zero. Therefore, the use of a declining royalty rate based on an initial rate for make-or-sell rights further reduces the reliability of the method used by P and S.

(iv) Sales of the next-generation product are not anticipated until after seven years, at which point the royalty rate will have declined to 1%. The temporal mismatch between the period of the royalty rate decline and the period of exploitation raises further concerns about the method's reliability.

(v) For the reasons given in paragraphs (ii) through (iv) of this Example 4, the method used by P and S is so unreliable and so contrary to provisions of this section that P and S could not reasonably conclude that they had contracted to make arm's length PCT Payments as required by paragraphs (b)(1)(ii) and (b)(3) of this section, and thus could not reasonably conclude that their arrangement was a CSA. Accordingly, the Commissioner is not required under paragraph (b)(5)(i) of this section to apply the rules of this section to their arrangement.

(vi) Nevertheless, the arrangement between P and S closely resembles a CSA. If the Commissioner concludes that that the rules of this section provide the most reliable measure of an arm's length result for such arrangement, then pursuant to paragraph (b)(5)(ii) of this section, the Commissioner may apply the rules of this section and make any appropriate allocations under paragraph (i) of this section. Alternatively, the Commissioner may conclude that the rules of this section do not provide the most reliable measure of an arm's length result. In such case, the arrangement would be analyzed under the methods under other section 482 regulations to determine whether the arrangement reaches an arm's length result.

(i) Presumed to be exclusive. For purposes of a PCT, the PCT Payee's provision of a platform contribution is presumed to be exclusive. Thus, it is presumed that the platform resource, capability, or right is not reasonably anticipated to be committed to any business activities other than the CSA Activity, as defined in paragraph (j)(1)(i) of this section, whether carried out by the controlled participants, other controlled taxpayers, or uncontrolled taxpayers.

(ii) Rebuttal of exclusivity. The controlled participants may rebut the presumption set forth in paragraph (c)(2)(i) of this section to the satisfaction of the Commissioner. For example, if the platform resource is a research tool, then the controlled participants could rebut the presumption by establishing to the satisfaction of the Commissioner that, as of the date of the PCT, the tool is reasonably anticipated not only to contribute to the CSA Activity but also to be licensed to an uncontrolled taxpayer. In such case, the PCT Payments may need to be prorated as described in paragraph (c)(2)(iii) of this section.

(iii) Proration of PCT Payments to the extent allocable to other business activities.

(i) In general. Any right to exploit an existing resource, capability, or right without further development of such item, such as the right to make, replicate, license, or sell existing products, does not constitute a platform contribution to a CSA (and the arm's length compensation for such rights (make-or-sell rights) does not satisfy the compensation obligation under a PCT) unless exploitation without further development of such item is reasonably anticipated to contribute to developing or further developing a cost shared intangible.

(ii) Examples. The following examples illustrate the principles of this paragraph (c)(4):

Example 1. P and S, which are members of the same controlled group, execute a CSA. Under the CSA, P and S will bear their RAB shares of IDCs for developing the second generation of ABC, a computer software program. Prior to that arrangement, P had incurred substantial costs and risks to develop ABC. Concurrent with entering into the arrangement, P (as the licensor) executes a license with S (as the licensee) by which S may make and sell copies of the existing ABC. Such make-or-sell rights do not constitute a platform contribution to the CSA. The rules of § § 1.482-1 and 1.482-4 through 1.482-6 must be applied to determine the arm's length consideration in connection with the make-or-sell licensing arrangement. In certain circumstances, this determination of the arm's length consideration may be done on an aggregate basis with the evaluation of compensation obligations pursuant to the PCTs entered into by P and S in connection with the CSA. See paragraph (g)(2)(iv) of this section.

Example 2. (i) P, a software company, has developed and currently exploits software program ABC. P and S enter into a CSA to develop future generations of ABC. The ABC source code is the platform on which future generations of ABC will be built and is therefore a platform contribution of P for which compensation is due from S pursuant to a PCT. Concurrent with entering into the CSA, P licenses to S the make-or-sell rights for the current version of ABC. P has entered into similar licenses with uncontrolled parties calling for sales-based royalty payments at a rate of 20%. The current version of ABC has an expected product life of three years. P and S enter into a contingent payment agreement to cover both the PCT Payments due from S for P's platform contribution and payments due from S for the make-or-sell license. Based on the uncontrolled make-or-sell licenses, P and S agree on a sales-based royalty rate of 20% in Year 1 that declines on a straight line basis to 0% over the 3 year product life of ABC.

(ii) The make-or-sell rights for the current version of ABC are not platform contributions, though paragraph (g)(2)(iv) of this section provides for the possibility that the most reliable determination of an arm's length charge for the platform contribution and the make-or-sell license may be one that values the two transactions in the aggregate. A contingent payment schedule based on the uncontrolled make-or-sell licenses may provide an arm's length charge for the separate make-or-sell license between P and S, provided the royalty rates in the uncontrolled licenses similarly decline, but as a measure of the aggregate PCT and licensing payments it does not account for the arm's length value of P's platform contributions which include the rights in the source code and future development rights in ABC.

Example 3. S is a controlled participant that owns Patent Q, which protects S's use of a research tool that is helpful in developing and testing new pharmaceutical compounds. The research tool, which is not itself such a compound, is used in the CSA Activity to develop such compounds. However, the CSA Activity is not anticipated to result in the further development of the research tool or in patents based on Patent Q. Although the right to use Patent Q is not anticipated to result in the further development of Patent Q or the technology that it protects, that right constitutes a platform contribution (as opposed to make-or-sell rights) because it is anticipated to contribute to the research activity to develop cost shared intangibles relating to pharmaceutical compounds covered by the CSA.

(i) Definition and scope of the IDA. For purposes of this section, the IDA means the activity under the CSA of developing or attempting to develop reasonably anticipated cost shared intangibles. The scope of the IDA includes all of the controlled participants' activities that could reasonably be anticipated to contribute to developing the reasonably anticipated cost shared intangibles. The IDA cannot be described merely by a list of particular resources, capabilities, or rights that will be used in the CSA, because such a list would not identify reasonably anticipated cost shared intangibles. Also, the scope of the IDA may change as the nature or identity of the reasonably anticipated cost shared intangibles changes or the nature of the activities necessary for their development become clearer. For example, the relevance of certain ongoing work to developing reasonably anticipated cost shared intangibles or the need for additional work may only become clear over time.

(ii) Reasonably anticipated cost shared intangible. For purposes of this section, reasonably anticipated cost shared intangible means any intangible, within the meaning of § 1.482-4(b), that, at the applicable point in time, the controlled participants intend to develop under the CSA. Reasonably anticipated cost shared intangibles may change over the course of the CSA. The controlled participants may at any time change the reasonably anticipated cost shared intangibles but must document any such change pursuant to paragraph (k)(2)(ii)(A)(1) of this section. Removal of reasonably anticipated cost shared intangibles does not affect the controlled participants' interests in cost shared intangibles already developed under the CSA. In addition, the reasonably anticipated cost shared intangibles automatically expand to include the intended result of any further development of a cost shared intangible already developed under the CSA, or applications of such an intangible. However, the controlled participants may override this automatic expansion in a particular case if they separately remove specified further development of such intangible (or specified applications of such intangible) from the IDA, and document such separate removal pursuant to paragraph (k)(2)(ii)(A)(3) of this section.

(iii) Costs included in IDCs. For purposes of this section, IDCs mean all costs, in cash or in kind (including stock-based compensation, as described in paragraph (d)(3) of this section), but excluding acquisition costs for land or depreciable property, in the ordinary course of business after the formation of a CSA that, based on analysis of the facts and circumstances, are directly identified with, or are reasonably allocable to, the IDA. Thus, IDCs include costs incurred in attempting to develop reasonably anticipated cost shared intangibles regardless of whether such costs ultimately lead to development of those intangibles, other intangibles developed unexpectedly, or no intangibles. IDCs shall also include the arm's length rental charge for the use of any land or depreciable tangible property (as determined under § 1.482-2(c) (Use of tangible property)) directly identified with, or reasonably allocable to, the IDA. Reference to generally accepted accounting principles or Federal income tax accounting rules may provide a useful starting point but will not be conclusive regarding inclusion of costs in IDCs. IDCs do not include interest expense, foreign income taxes (as defined in § 1.901-2(a)), or domestic income taxes.

(iv) Examples. The following examples illustrate the principles of this paragraph (d)(1):

Example 1. A contract that purports to be a CSA provides that the IDA to which the agreement applies consists of all research and development activity conducted at laboratories A, B, and C but not at other facilities maintained by the controlled participants. The contract does not describe the reasonably anticipated cost shared intangibles with respect to which research and development is to be undertaken. The contract fails to meet the requirements set forth in paragraph (k)(1)(ii)(B) of this section because it fails to adequately describe the scope of the IDA to be undertaken.

Example 2. A contract that purports to be a CSA provides that the IDA to which the agreement applies consists of all research and development activity conducted by any of the controlled participants with the goal of developing a cure for a particular disease. Such a cure is thus a reasonably anticipated cost shared intangible. The contract also contains a provision that the IDA will exclude any activity that builds on the results of the controlled participants' prior research concerning Enzyme X even though such activity could reasonably be anticipated to contribute to developing such cure. The contract fails to meet the requirement set forth in paragraph (d)(1)(i) of this section that the scope of the IDA include all of the controlled participants' activities that could reasonably be anticipated to contribute to developing reasonably anticipated cost shared intangibles.

(i) In general. As used in this section, the term stock-based compensation means any compensation provided by a controlled participant to an employee or independent contractor in the form of equity instruments, options to acquire stock (stock options), or rights with respect to (or determined by reference to) equity instruments or stock options, including but not limited to property to which section 83 applies and stock options to which section 421 applies, regardless of whether ultimately settled in the form of cash, stock, or other property.

(ii) Identification of stock-based compensation with the IDA. The determination of whether stock-based compensation is directly identified with, or reasonably allocable to, the IDA is made as of the date that the stock-based compensation is granted. Accordingly, all stock-based compensation that is granted during the term of the CSA and, at date of grant, is directly identified with, or reasonably allocable to, the IDA is included as an IDC under paragraph (d)(1) of this section. In the case of a repricing or other modification of a stock option, the determination of whether the repricing or other modification constitutes the grant of a new stock option for purposes of this paragraph (d)(3)(ii) will be made in accordance with the rules of section 424(h) and related regulations.

(iii) Measurement and timing of stock-based compensation IDC.

(i) In general. A controlled participant's share of reasonably anticipated benefits is equal to its reasonably anticipated benefits divided by the sum of the reasonably anticipated benefits, as defined in paragraph (j)(1)(i) of this section, of all the controlled participants. RAB shares must be updated to account for changes in economic conditions, the business operations and practices of the participants, and the ongoing development of intangibles under the CSA. For purposes of determining RAB shares at any given time, reasonably anticipated benefits must be estimated over the entire period, past and future, of exploitation of the cost shared intangibles, and must reflect appropriate updates to take into account the most reliable data regarding past and projected future results available at such time. RAB shares determined for a particular purpose shall not be further updated for that purpose based on information not available at the time that determination needed to be made. For example, RAB shares determined in order to determine IDC shares for a particular taxable year (as set forth in paragraphs (b)(1)(i) and (d)(4) of this section) shall not be recomputed based on information not available at that time. Similarly, RAB shares determined for the purpose of using a particular method such as the acquisition price method (as set forth in paragraph (g)(5)(ii) of this section) to evaluate the arm's length amount charged in a PCT shall not be recomputed based on information not available at the date of that PCT. However, nothing in this paragraph (e)(1)(i) shall limit the Commissioner's use of subsequently available information for purposes of its allocation determinations in accordance with the provisions of paragraph (i) (Allocations by the Commissioner in connection with a CSA) of this section.

(ii) Reliability. A controlled participant's RAB share must be determined by using the most reliable estimate. In determining which of two or more available estimates is most reliable, the quality of the data and assumptions used in the analysis must be taken into account, consistent with § 1.482-1(c)(2)(ii) (Data and assumptions). Thus, the reliability of an estimate will depend largely on the completeness and accuracy of the data, the soundness of the assumptions, and the relative effects of particular deficiencies in data or assumptions on different estimates. If two estimates are equally reliable, no adjustment should be made based on differences between the estimates. The following factors will be particularly relevant in determining the reliability of an estimate of RAB shares:

(iii) Examples. The following examples illustrate the principles of this paragraph (e)(1):

Example 1. (i) USP and FS plan to conduct research to develop Product Lines A and B. USP and FS reasonably anticipate respective benefits from Product Line A of 100X and 200X and respective benefits from Product Line B, respectively, of 300X and 400X. USP and FS thus reasonably anticipate combined benefits from Product Lines A and B of 400X and 600X, respectively.

(ii) USP and FS could enter into a separate CSA to develop Product Line A with respective RAB shares of 33 1/3 percent and 66 2/3 percent (reflecting a ratio of 100X to 200X), and into a separate CSA to develop Product Line B with respective RAB shares of 42 6/7 percent and 57 1/7 percent (reflecting a ratio of 300X to 400X). Alternatively, USP and FS could enter into a single CSA to develop both Product Lines A and B with respective RAB shares of 40 percent and 60 percent (in the ratio of 400X to 600X). If the separate CSAs are chosen, then any costs for activities that contribute to developing both Product Line A and Product Line B will constitute IDCs of the respective CSAs as required by paragraphs (d)(1) and (2) of this section.

Example 2. (i) USP, a US company, wholly owns foreign subsidiary, FS. USP and FS enter into a CSA at the start of Year 1. The CSA's total IDCs are $100,000 in each year for Years 1 through 4. In Year 1, USP correctly estimates its RAB share as 50%, based on information available at the time, and therefore correctly computes $50,000 as its cost contribution for Year 1.

(ii) In Year 4, USP correctly estimates its RAB share to be 70%, based on information available at the time and, therefore, correctly computes $70,000 as its cost contribution for Year 4.

(iii) In Year 4, USP also files an amended return for Year 1 in which USP deducts a cost contribution of $70,000, asserting that, for this purpose, it should revise its Year 1 estimated RAB share to 70% based on the information that is now available to it in Year 4. The Commissioner determines that USP is incorrect for two reasons. First, a RAB share determined for a particular purpose (here, to determine USP's IDC shares and thus USP's cost contributions in Year 1) should not be revised based on information not available to USP until Year 4. See paragraph (e)(1)(i) of this section. Second, more generally, USP is not permitted to file an amended return for this purpose under § 1.482-1(a)(3). Therefore, for both of these reasons, Commissioner adjusts USP's amended return for Year 1 by disallowing $20,000 of the $70,000 deduction.

(i) In general. In order to estimate a controlled participant's RAB share, the amount of each controlled participant's reasonably anticipated benefits must be measured on a basis that is consistent for all such participants. See paragraph (e)(2)(ii)(E) Example 9 of this section. If a controlled participant transfers a cost shared intangible to another controlled taxpayer, other than by way of a transfer described in paragraph (f) of this section, that controlled participant's benefits from the transferred intangible must be measured by reference to the transferee's benefits, disregarding any consideration paid by the transferee to the controlled participant (such as a royalty pursuant to a license agreement). Reasonably anticipated benefits are measured either on a direct basis, by reference to estimated benefits to be generated by the use of cost shared intangibles (generally based on additional revenues plus cost savings less any additional costs incurred), or on an indirect basis, by reference to certain measurements that reasonably can be assumed to relate to benefits to be generated. Such indirect bases of measurement of anticipated benefits are described in paragraph (e)(2)(ii) of this section. A controlled participant's reasonably anticipated benefits must be measured on the basis, whether direct or indirect, that most reliably determines RAB shares. In determining which of two bases of measurement is most reliable, the factors set forth in § 1.482-1(c)(2)(ii) (Data and assumptions) must be taken into account. It normally will be expected that the basis that provided the most reliable estimate for a particular year will continue to provide the most reliable estimate in subsequent years, absent a material change in the factors that affect the reliability of the estimate. Regardless of whether a direct or indirect basis of measurement is used, adjustments may be required to account for material differences in the activities that controlled participants undertake to exploit their interests in cost shared intangibles. See Examples 4 and 7 of paragraph (e)(2)(ii)(E) of this section.

(ii) Indirect bases for measuring anticipated benefits. Indirect bases for measuring anticipated benefits from participation in a CSA include the following:

(iii) Projections used to estimate benefits.

(i) The comparable uncontrolled transaction method described in § 1.482-4(c), or the comparable uncontrolled services price method described in § 1.482-9(c), as further described in paragraph (g)(3) of this section;

(ii) The income method, described in paragraph (g)(4) of this section;

(iii) The acquisition price method, described in paragraph (g)(5) of this section;

(iv) The market capitalization method, described in paragraph (g)(6) of this section;

(v) The residual profit split method, described in paragraph (g)(7) of this section; and

(vi) Unspecified methods, described in paragraph (g)(8) of this section.

(i) In general. Each method must be applied in accordance with the provisions of § 1.482-1, including the best method rule of § 1.482-1(c), the comparability analysis of § 1.482-1(d), and the arm's length range of § 1.482-1(e), except as those provisions are modified in this paragraph (g).

(ii) Consistency with upfront contractual terms and risk allocation -- the investor model.

(iii) Consistency of evaluation with realistic alternatives.

(iv) Aggregation of transactions. The combined effect of multiple contemporaneous transactions, consisting either of multiple PCTs, or of one or more PCT and one or more other transactions in connection with a CSA that are not governed by this section (such as transactions involving cross operating contributions or make-or-sell rights), may require evaluation in accordance with the principles of aggregation described in § 1.482-1(f)(2)(i). In such cases, it may be that the multiple transactions are reasonably anticipated, as of the date of the PCT(s), to be so interrelated that the method that provides the most reliable measure of an arm's length charge is a method under this section applied on an aggregate basis for the PCT(s) and other transactions. A section 482 adjustment may be made by comparing the aggregate arm's length charge so determined to the aggregate payments actually made for the multiple transactions. In such a case, it generally will not be necessary to allocate separately the aggregate arm's length charge as between various PCTs or as between PCTs and such other transactions. However, such an allocation may be necessary for other purposes, such as applying paragraph (i)(6) (Periodic adjustments) of this section. An aggregate determination of the arm's length charge for multiple transactions will often yield a payment for a controlled participant that is equal to the aggregate value of the platform contributions and other resources, capabilities, and rights covered by the multiple transactions multiplied by that controlled participant's RAB share. Because RAB shares only include benefits from cost shared intangibles, the reliability of an aggregate determination of payments for multiple transactions may be reduced to the extent that it includes transactions covering resources, capabilities, and rights for which the controlled participants' expected benefit shares differ substantially from their RAB shares.

(v) Discount rate.

(vi) Financial projections. The reliability of an estimate of the value of a platform or operating contribution in connection with a PCT will often depend upon the reliability of projections used in making the estimate. Such projections should reflect the best estimates of the items projected (normally reflecting a probability weighted average of possible outcomes and thus also reflecting non-market-correlated risk). Projections necessary for this purpose may include a projection of sales, IDCs, costs of developing operating contributions, routine operating expenses, and costs of sales. Some method applications directly estimate projections of items attributable to separate development and exploitation by the controlled participants within their respective divisions. Other method applications indirectly estimate projections of items from the perspective of the controlled group as a whole, rather than from the perspective of a particular participant, and then apportion the items so estimated on some assumed basis. For example, in some applications, sales might be directly projected by division, but worldwide projections of other items such as operating expenses might be apportioned among divisions in the same ratio as the divisions' respective sales. Which approach is more reliable depends on which provides the most reliable measure of an arm's length result, considering the competing perspectives under the facts and circumstances in light of the completeness and accuracy of the underlying data, the reliability of the assumptions, and the sensitivity of the results to possible deficiencies in the data and assumptions. For these purposes, projections that have been prepared for non-tax purposes are generally more reliable than projections that have been prepared solely for purposes of meeting the requirements in this paragraph (g).

(vii) Accounting principles.

(viii) Valuations of subsequent PCTs.

(ix) Arm's length range.

(x) Valuation undertaken on a pre-tax basis. PCT Payments in general may increase the PCT Payee's tax liability and decrease the PCT Payor's tax liability. The arm's length amount of a PCT Payment determined under the methods in this paragraph (g) is the value of the PCT Payment itself, without regard to such tax effects. Therefore, the methods under this section must be applied, with suitable adjustments if needed, to determine the PCT Payments on a pre-tax basis. See paragraphs (g)(2)(v)(B) and (4)(i)(G) of this section.

(i) In general.

(ii) Evaluation of PCT Payor's cost sharing alternative. The present value of the PCT Payor's cost sharing alternative is the present value of the stream of the reasonably anticipated residuals over the duration of the CSA Activity of divisional profits or losses, minus operating cost contributions, minus cost contributions, minus PCT Payments.

(iii) Evaluation of PCT Payor's licensing alternative.

(iv) Lump sum payment form. Where the form of PCT Payment is a lump sum as of the date of the PCT, then, based on paragraphs (g)(4)(i) through (iii) of this section, the PCT Payment equals the difference between --

(v) Application of income method using differential income stream. In some cases, the present value of an arm's length PCT Payment may be determined as the present value, discounted at the appropriate rate, of the PCT Payor's reasonably anticipated stream of additional positive or negative income over the duration of the CSA Activity that would result (before PCT Payments) from undertaking the cost sharing alternative rather than the licensing alternative (differential income stream). See Example 9 of paragraph (g)(4)(viii) of this section.

(vi) Best method analysis considerations.

(vii) Routine platform and operating contributions. For purposes of this paragraph (g)(4), any routine contributions that are platform or operating contributions, the valuation and PCT Payments for which are determined and made independently of the income method, are treated similarly to cost contributions and operating cost contributions, respectively. Accordingly, wherever used in this paragraph (g)(4), the term "routine contributions" shall not include routine platform or operating contributions, and wherever the terms "cost contributions" and "operating cost contributions" appear in this paragraph, they shall include net routine platform contributions and net routine operating contributions, respectively. Net routine platform contributions are the value of a controlled participant's total reasonably anticipated routine platform contributions, plus its reasonably anticipated PCT Payments to other controlled participants in respect of their routine platform contributions, minus the reasonably anticipated PCT Payments it is to receive from other controlled participants in respect of its routine platform contributions. Net routine operating contributions are the value of a controlled participant's total reasonably anticipated routine operating contributions, plus its reasonably anticipated arm's length compensation to other controlled participants in respect of their routine operating contributions, minus the reasonably anticipated arm's length compensation it is to receive from other controlled participants in respect of its routine operating contributions.

(viii) Examples. The following examples illustrate the principles of this paragraph (g)(4):

Example 1. (i) For simplicity of calculation in this Example 1, all financial flows are assumed to occur at the beginning of each period. USP, a software company, has developed version 1.0 of a new software application that it is currently marketing. In Year 1 USP enters into a CSA with its wholly-owned foreign subsidiary, FS, to develop future versions of the software application. Under the CSA, USP will have the rights to exploit the future versions in the United States, and FS will have the rights to exploit them in the rest of the world. The future rights in version 1.0, and USP's development team, are reasonably anticipated to contribute to the development of future versions and therefore the rights in version 1.0 and the research and development team are platform contributions for which compensation is due from FS as part of a PCT. USP does not transfer the current exploitation rights in version 1.0 to FS. FS will not perform any research or development activities and does not furnish any platform contributions nor does it control any operating intangibles at the inception of the CSA that would be relevant to the exploitation of version 1.0 or future versions of the software.

(ii) FS undertakes financial projections in its territory of the CSA:

FS anticipates that activity on this application will cease after Year 15. The application was derived from software developed by Company Q, an uncontrolled party. FS has a license under Company Q's copyright, but that license expires after Year 15 and will not be renewed.

(iii) In evaluating the cost sharing alternative, FS concludes that the cost sharing alternative represents a riskier alternative for FS than the licensing alternative because, in cost sharing, FS will take on the additional risks associated with cost contributions. Taking this difference into account, FS concludes that the appropriate discount rate to apply in assessing the licensing alternative, based on discount rates of comparable uncontrolled companies undertaking comparable licensing transactions, would be 13% per year, whereas the appropriate discount rate to apply in assessing the cost sharing alternative would be 15% per year. FS determines that the arm's length rate USP would have charged an uncontrolled licensee for a license of future versions of the software (if USP had further developed version 1.0 on its own) is 35% of the sales price, as determined under the CUT method in § 1.482-4(c). FS also determines that the tax rate applicable to it will be the same in the licensing alternative as in the CSA. Accordingly, the financial projections associated with the licensing alternative are:

(iv) Based on these projections and applying the appropriate discount rate, FS determines that under the cost sharing alternative, the present value of the stream of residuals of its anticipated divisional profits, reduced by the anticipated operating cost contributions and cost contributions, but not reduced by any PCT Payments (that is, the stream of anticipated operating income as shown in column 5) would be $889 million. Under the licensing alternative, the present value of the stream of residuals of its anticipated divisional profits and losses minus the operating cost contributions (that is, the stream of anticipated operating income before licensing payments, which is the present value of column 7 reduced by column 8) would be $1.419 billion, and the present value of the licensing payments would be $994 million. Therefore, the total value of the licensing alternative would be $425 million. In order for the present value of the cost sharing alternative to equal the present value of the licensing alternative, the present value of the PCT Payments must equal $464 million. Therefore, the taxpayer makes and reports PCT Payments with a present value of $464 million.

Example 2. Arm's length range. (i) The facts are the same as in Example 1. The Commissioner accepts the financial projections undertaken by FS. Further , the Commissioner determines that the licensing discount rate and the CUT licensing rate are most reliably determined by reference to comparable uncontrolled discount rates and license rates, respectively. The observations that are in the interquartile range of the respective input parameters (see paragraph (g)(2)(ix) of this section) are as follows:

(ii) Following the principles of paragraph (g)(2)(ix) of this section, the Commissioner undertakes 25 different applications of the income method, using each combination of the discount rate and licensing rate parameters. In undertaking this analysis, the Commissioner assumes that the ratio of the median discount rate for the cost sharing alternative to the median discount rate for the licensing alternative (that is, 15% to 13%) is maintained. The results of the 25 applications of the income method, sorted in ascending order of calculated present value of the PCT Payment, are as follows:

(iii) Accordingly, the Commissioner determines that a taxpayer will not be subject to adjustment if its initial (ex ante) determination of the present value of PCT Payments is between $354 million and $520 million (the lower and upper quartile results as shown in the last column). Because FS's determination of the present value of the PCT Payments, $464 million, is within the interquartile range, no adjustments are warranted.

Example 3. (i) For simplicity of calculation in this Example 3, all financial flows are assumed to occur at the beginning of each period. USP, a U.S. software company, has developed version 1.0 of a new software application, employed to store and retrieve complex data sets in certain types of storage media. Version 1.0 is currently being marketed. In Year 1, USP enters into a CSA with its wholly-owned foreign subsidiary, FS, to develop future versions of the software application. Under the CSA, USP will have the exclusive rights to exploit the future versions in the U.S., and FS will have the exclusive rights to exploit them in the rest of the world. USP's rights in version 1.0, and its development team, are reasonably anticipated to contribute to the development of future versions of the software application and, therefore, the rights in version 1.0 are platform contributions for which compensation is due from FS as part of a PCT. USP also transfers the current exploitation rights in version 1.0 to FS and the arm's length amount of the compensation for such transfer is determined in the aggregate with the arm's length PCT Payments in this Example 3. FS does not furnish any platform contributions to the CSA nor does it control any operating intangibles at the inception of the CSA that would be relevant to the exploitation of version 1.0 or future versions of the software. It is reasonably anticipated that FS will have gross sales of $1000X in its territory for 5 years attributable to its exploitation of version 1.0 and the cost shared intangibles, after which time the software application will be rendered obsolete and unmarketable by the obsolescence of the storage medium technology to which it relates. FS's costs reasonably attributable to the CSA, other than cost contributions and operating cost contributions, are anticipated to be $250X per year. Certain operating cost contributions that will be borne by FS are reasonably anticipated to equal $200X per annum for 5 years. In addition, FS is reasonably anticipated to pay cost contributions of $200X per year as a controlled participant in the CSA.

(ii) FS concludes that its realistic alternative would be to license software from an uncontrolled licensor that would undertake the commitment to bear the entire risk of software development. Applying CPM using the profit levels experienced by uncontrolled licensees with contractual provisions and allocations of risk that are comparable to those of FS's licensing alternative, FS determines that it could, as a licensee, reasonably expect a (pre-tax) routine return equal to 14% of gross sales or $140X per year for 5 years. The remaining net revenue would be paid to the uncontrolled licensor as a license fee of $410X per year. FS determines that the discount rate that would be applied to determine the present value of income and costs attributable to its participation in the licensing alternative would be 12.5% as compared to the 15% discount rate that would be applicable in determining the present value of the net income attributable to its participation in the CSA (reflecting the increased risk borne by FS in bearing a share of the R & D costs in the cost sharing alternative). FS also determines that the tax rate applicable to it will be the same in the licensing alternative as in the CSA.

(iii) On these facts, the present value to FS of entering into the cost sharing alternative equals the present value of the annual divisional profits ($1,000X minus $250X) minus operating cost contributions ($200X) minus cost contributions ($200X) minus PCT Payments, determined over 5 years by discounting at a discount rate of 15%. Thus, the present value of the residuals, prior to subtracting the present value of the PCT Payments, is $1349X.

(iv) On these facts, the present value to FS of entering into the licensing alternative would be $561X determined by discounting, over 5 years, annual divisional profits ($1,000X minus $250X) minus operating cost contributions ($200X) and licensing payments ($410X) at a discount rate of 12.5% per annum. The present value of the cost sharing alternative must also equal $561X but equals $1349X prior to subtracting the present value of the PCT Payments. Consequently, the PCT Payments must have a present value of $788X.

Example 4. Pre-tax PCT Payment derived from post-tax information. (i) For simplicity of calculation in this Example 4, it is assumed that all payments are made at the end of each year. Domestic controlled participant USP has developed a technology, Z, that it would like to exploit for three years in a CSA. USP enters into a CSA with its wholly-owned foreign subsidiary, FS, that provides for PCT Payments from FS to USP with respect to USP's platform contribution to the CSA of Z in the form of three annual installment payments due from FS to USP on the last day of each of the first three years of the CSA. FS makes no platform contributions to the CSA. Prior to entering into the CSA, FS considers that it has the realistic alternative available to it of licensing Z from USP rather than entering into a CSA with USP to further develop Z for three years.

(ii) FS undertakes financial projections for both the licensing and cost sharing alternatives for exploitation of Z in its territory of the CSA. These projections are set forth in the following tables. The example assumes that there is a reasonably anticipated effective tax rate of 25% in each of years 1 through 3 under both the licensing and cost sharing alternatives. FS determines that the appropriate post-tax discount rate under the licensing alternative is 12.5%, and that the appropriate post-tax discount rate under the cost sharing alternative is 15%.

(iii) Under paragraph (g)(4) of this section, the arm's length charge for a PCT Payment will be an amount such that a controlled participant's present value, as of the date of the PCT of its cost sharing alternative of entering into a CSA equals the present value of its best realistic alternative. This requires that L, the present value of the post-tax income under the CSA, equals the present value of the post-tax income under the licensing alternative, or $196.

(iv) FS determines that PCT Payments for Z should be $196 in Year 1 (A), $215 in Year 2 (B), and $236 in Year 3 (C). By using these amounts for A, B, and C in the table above, FS is able to derive the values of E, F, G, I, J, and K in the table above. Based on these PCT Payments for Z, the post-tax income will be $78 in Year 1 (I), $86 in Year 2 (J), and $95 in Year 3 (K). When this post-tax income stream is discounted at the appropriate rate for the cost sharing alternative (15%), the net present value is $196 (L). The present value of the PCT Payments, when discounted at the appropriate post-tax rate, is $488 (D).

(v) The Commissioner undertakes an audit of the PCT Payments made by FS to USP for Z in Years 1 through 3. The Commissioner concludes that the PCT Payments for Z are arm's length in accordance with this paragraph (g)(4).

Example 5. Pre-tax PCT Payment derived from post-tax information. (i) The facts are the same as in paragraphs (i) and (ii) of Example 4. In addition, under this paragraph (g)(4), the arm's length charge for a PCT Payment will be an amount such that a controlled participant's present value, as of the date of the PCT of its cost sharing alternative equals the present value of its best realistic alternative. This requires that L, the present value of the post-tax income under the CSA, equals the present value of the post-tax income under the licensing alternative, or $196.

(ii) FS determines that the post-tax present value of the cost sharing alternative (excluding PCT Payments) is $562. The post-tax present value of the licensing alternative is $196. Accordingly, payments with a post-tax present value of $366 are required.

(iii) The Commissioner undertakes an audit of the PCT Payments made by FS to USP for Z in Years 1 through 3. In correspondence to the Commissioner, USP maintains that the arm's length PCT Payment for Z should have a present value of $366 (D).

(iv) The Commissioner considers that if FS makes PCT Payments for Z with a present value of $366, then the post-tax present value under the CSA (considering the deductibility of the PCT Payments) will be $287, substantially higher than the post-tax present value of the licensing arrangement, $196. The Commissioner determines that, under the specific facts and assumptions of this example, the present value of the post-tax payments may be grossed up by a factor of (one minus the tax rate), resulting in a present value of pre-tax payments of $488. Accordingly, FS must make yearly PCT Payments (A, B, and C) such that the present value of the Payments is $488 (D). (When FS's post-tax income after these PCT Payments for Z is discounted at the appropriate rate for the cost sharing alternative (15%), the net present value is $196 (L), which is equal to the present value of post-tax income under the licensing alternative.) The Commissioner concludes that the calculations that it has made for the PCT Payments for Z are arm's length in accordance with this paragraph (g)(4) and, accordingly, makes the appropriate adjustments to USP's income tax return to account for the gross-up required by paragraph (g)(2)(x) of this section.

Example 6. Pre-tax PCT Payment derived from pre-tax information. (i) The facts are the same as in paragraphs (i) and (ii) of Example 4. In addition, under paragraph (g)(4) of this section, the arm's length charge for a PCT Payment will be an amount such that a controlled participant's present value, as of the date of the PCT of its cost sharing alternative of entering into a CSA equals the present value of its best realistic alternative. This requires that "L," the present value of the post-tax income under the CSA, equals the present value of the post-tax income under the licensing alternative, or $196.

(ii) Under the specific facts and assumptions of this Example 6 (see paragraph (g)(4)(i)(G) of this section), and using the same (post-tax) discount rates as in Example 4, the present value of pre-tax income under the licensing alternative (that is, the operating income) is $261, and the present value of pretax income under the cost sharing alternative (excluding PCT Payments) is $749. Accordingly, FS determines that its PCT Payments for Z should have a present value equal to the difference between the two, or $488 (D). Such PCT Payments for Z result in a present value of post-tax income under the cost sharing alternative of $196 (L), which is equal to the present value of post-tax income under the licensing alternative.

(iii) The Commissioner undertakes an audit of the PCT Payments for Z made by FS to USP in Years 1 through 3. The Commissioner concludes that the PCT Payments for Z are arm's length in accordance with this paragraph (g)(4).

Example 7. Application of income method with a terminal value calculation. (i) For simplicity of calculation in this Example 7, all financial flows are assumed to occur at the beginning of each period. USP's research and development team, Q, has developed a technology, Z, for which it has several applications on the market now and several planned for release at future dates. In Year 1, USP, enters into a CSA with its wholly-owned subsidiary, FS, to develop future applications of Z. Under the CSA, USP will have the rights to further develop and exploit the future applications of Z in the United States, and FS will have the rights to further develop and exploit the future applications of Z in the rest of the world. Both Q and the rights to further develop and exploit future applications of Z are reasonably anticipated to contribute to the development of future applications of Z. Therefore, both Q and the rights to further develop and exploit the future applications of Z are platform contributions for which compensation is due from FS to USP as part of a PCT. USP does not transfer the current exploitation rights for current applications of Z to FS. FS will not perform any research or development activities on Z and does not furnish any platform contributions to the CSA, nor does it control any operating intangibles at the inception of the CSA that would be relevant to the exploitation of either current or future applications of Z.

(ii) At the outset of the CSA, FS undertakes an analysis of the PCTs involving Q and the rights with respect to Z in order to determine the arm's length PCT Payments owing from FS to USP under the CSA. In that evaluation, FS concludes that the cost sharing alternative represents a riskier alternative for FS than the licensing alternative. FS further concludes that the appropriate discount rate to apply in assessing the licensing alternative, based on discount rates of comparable uncontrolled companies undertaking comparable licensing transactions, would be 13% per annum, whereas the appropriate discount rate to apply in assessing the cost sharing alternative would be 14% per annum. FS undertakes financial projections and anticipates making $100 million in sales during the first two years of the CSA in its territory with sales in Years 3 through 8 increasing to $200 million, $400 million, $600 million, $650 million, $700 million, and $750 million, respectively. After Year 8, FS expects its sales of all products based upon exploitation of Z in the rest of the world to grow at 3% per annum for the future. FS and USP do not anticipate cessation of the CSA Activity with respect to Z at any determinable date. FS anticipates that its manufacturing and distribution costs for exploiting Z (including its operating cost contributions), will equal 60% of gross sales of Z from Year 1 onwards, and anticipates its cost contributions will equal $25 million per annum for Years 1 and 2, $50 million per annum for Years 3 and 4, and 10% of gross sales per annum thereafter.

(iii) Based on this analysis, FS determines that the arm's length royalty rate that USP would have charged an uncontrolled licensee for a license of future applications of Z if USP had further developed future applications of Z on its own is 30% of the sales price of the Z-based product, as determined under the comparable uncontrolled transaction method in § 1.482-4(c). In light of the expected sales growth and anticipation that the CSA Activity will not cease as of any determinable date, FS's determination includes a terminal value calculation. FS further determines that under the cost sharing alternative, the present value of FS's divisional profits, reduced by the present values of the anticipated operating cost contributions and cost contributions, would be $1,361 million. Under the licensing alternative, the present value of the operating divisional profits and losses, reduced by the operating cost contributions, would be $2,113 million, and the present value of the licensing payments would be $1,585 million. Therefore, the total value of the licensing alternative would be $528 million. In order for the present value of the cost sharing alternative to equal the present value of the licensing alternative, the present value of the PCT Payments must equal $833 million. Accordingly, FS pays USP a lump sum PCT Payment of $833 million in Year 1 for USP's platform contributions of Z and Q.

(iv) The Commissioner undertakes an audit of the PCTs and concludes, based on his own analysis, that this lump sum PCT Payment is within the interquartile range of arm's length results for these platform contributions. The calculations made by FS in determining the PCT Payment in this Example 7 are set forth in the following tables:

Example 8. (i) The facts are the same as in Example 1, except that the taxpayer determines that the appropriate discount rate for the cost sharing alternative is 20%. In addition, the taxpayer determines that the appropriate discount rate for the licensing alternative is 10%. Accordingly, the taxpayer determines that the appropriate present value of the PCT Payment is $146 million.

(ii) Based on the best method analysis described in Example 2, the Commissioner determines that the taxpayer's calculation of the present value of the PCT Payments is outside of the interquartile range (as shown in the sixth column of Example 2), and thus warrants an adjustment. Furthermore, in evaluating the taxpayer's analysis, the Commissioner undertakes an analysis based on the difference in the financial projections between the cost sharing and licensing alternatives (as shown in column 11 of Example 1). This column shows the anticipated differential income stream of additional positive or negative income for FS over the duration of the CSA Activity that would result from undertaking the cost sharing alternative (before any PCT Payments) rather than the licensing alternative. This anticipated differential income stream thus reflects the anticipated incremental undiscounted profits to FS from the incremental activity of undertaking the risk of developing the cost shared intangibles and enjoying the value of its divisional interests. Taxpayer's analysis logically implies that the present value of this stream must be $146 million, since only then would FS have the same anticipated value in both the cost sharing and licensing alternatives. A present value of $146 million implies that the discount rate applicable to this stream is 34.4%. Based on a reliable calculation of discount rates applicable to the anticipated income streams of uncontrolled companies whose resources, capabilities, and rights consist primarily of software applications intangibles and research and development teams similar to USP's platform contributions to the CSA, and which income streams, accordingly, may be reasonably anticipated to reflect a similar risk profile to the differential income stream, the Commissioner concludes that an appropriate discount rate for the anticipated income stream associated with USP's platform contributions (that is, the additional positive or negative income over the duration of the CSA Activity that would result, before PCT Payments, from switching from the licensing alternative to the cost sharing alternative) is 16%, which is significantly less than 34.4%. This conclusion further suggests that Taxpayer's analysis is unreliable. See paragraphs (g)(2)(v)(B)(2) and (g)(4)(vi)(F)(1) and (2) of this section.

(iii) The Commissioner makes an adjustment of $296 million, so that the present value of the PCT Payments is $442 million (the median results as shown in column 6 of Example 2).

Example 9. The facts are the same as in Example 1, except that additional data on discount rates are available that were not available in Example 1. The Commissioner determines the arm's length charge for the PCT Payment by discounting at an appropriate rate the differential income stream associated with the rights contributed by USP in the PCT (that is, the stream of income in column (11) of Example 1). Based on an analysis of a set of public companies whose resources, capabilities, and rights consist primarily of resources, capabilities, and rights similar to those contributed by USP in the PCT, the Commissioner determines that 15% to 17% is an appropriate range of discount rates to use to assess the value of the differential income stream associated with the rights contributed by USP in the PCT. The Commissioner determines that applying a discount rate of 17% to the differential income stream associated with the rights contributed by USP in the PCT yields a present value of $446 million, while applying a discount rate of 15% to the differential income stream associated with the rights contributed by USP in the PCT yields a present value of $510 million. Because the taxpayer's result, $464 million, is within the interquartile range determined by the Commissioner, no adjustments are warranted. See paragraphs (g)(2)(v)(B)(2), (g)(4)(v), and (g)(4)(vi)(F)(1) of this section.

(i) In general. The acquisition price method applies the comparable uncontrolled transaction method of § 1.482-4(c), or the comparable uncontrolled services price method described in § 1.482-9(c), to evaluate whether the amount charged in a PCT, or group of PCTs, is arm's length by reference to the amount charged (the acquisition price) for the stock or asset purchase of an entire organization or portion thereof (the target) in an uncontrolled transaction. The acquisition price method is ordinarily used where substantially all the target's nonroutine contributions, as such term is defined in paragraph (j)(1)(i) of this section, made to the PCT Payee's business activities are covered by a PCT or group of PCTs.

(ii) Determination of arm's length charge. Under this method, the arm's length charge for a PCT or group of PCTs covering resources, capabilities, and rights of the target is equal to the adjusted acquisition price, as divided among the controlled participants according to their respective RAB shares.

(iii) Adjusted acquisition price. The adjusted acquisition price is the acquisition price of the target increased by the value of the target's liabilities on the date of the acquisition, other than liabilities not assumed in the case of an asset purchase, and decreased by the value of the target's tangible property on that date and by the value on that date of any other resources, capabilities, and rights not covered by a PCT or group of PCTs.

(iv) Best method analysis considerations. The comparability and reliability considerations stated in § 1.482-4(c)(2) apply. Consistent with those considerations, the reliability of applying the acquisition price method as a measure of the arm's length charge for the PCT Payment normally is reduced if --

(v) Example. The following example illustrates the principles of this paragraph (g)(5):

Example. USP, a U.S. corporation, and its newly incorporated, wholly-owned foreign subsidiary (FS) enter into a CSA at the start of Year 1 to develop Group Z products. Under the CSA, USP and FS will have the exclusive rights to exploit the Group Z products in the U.S. and the rest of the world, respectively. At the start of Year 2, USP acquires Company X for cash consideration worth $110 million. At this time USP's RAB share is 60%, and FS's RAB share is 40% and is not reasonably anticipated to change as a result of this acquisition. Company X joins in the filing of a U.S. consolidated income tax return with USP. Under paragraph (j)(2)(i) of this section, Company X and USP are treated as one taxpayer for purposes of this section. Accordingly, the rights in any of Company X's resources and capabilities that are reasonably anticipated to contribute to the development activities of the CSA will be considered platform contributions furnished by USP. Company X's resources and capabilities consist of its workforce, certain technology intangibles, $15 million of tangible property and other assets and $5 million in liabilities. The technology intangibles, as well as Company X's workforce, are reasonably anticipated to contribute to the development of the Group Z products under the CSA and, therefore, the rights in the technology intangibles and the workforce are platform contributions for which FS must make a PCT Payment to USP. None of Company X's existing intangible assets or any of its workforce are anticipated to contribute to activities outside the CSA. For purposes of this example, it is assumed that no additional adjustment on account of tax liabilities is needed. Applying the acquisition price method, the value of USP's platform contributions is the adjusted acquisition price of $100 million ($110 million acquisition price plus $5 million liabilities less $15 million tangible property and other assets). FS must make a PCT Payment to USP for these platform contributions with a reasonably anticipated present value of $40 million, which is the product of $100 million (the value of the platform contributions) and 40% (FS's RAB share).

(i) In general. The market capitalization method applies the comparable uncontrolled transaction method of § 1.482-4(c), or the comparable uncontrolled services price method described in § 1.482-9(c), to evaluate whether the amount charged in a PCT, or group of PCTs, is arm's length by reference to the average market capitalization of a controlled participant (PCT Payee) whose stock is regularly traded on an established securities market. The market capitalization method is ordinarily used where substantially all of the PCT Payee's nonroutine contributions to the PCT Payee's business are covered by a PCT or group of PCTs.

(ii) Determination of arm's length charge. Under the market capitalization method, the arm's length charge for a PCT or group of PCTs covering resources, capabilities, and rights of the PCT Payee is equal to the adjusted average market capitalization, as divided among the controlled participants according to their respective RAB shares.

(iii) Average market capitalization. The average market capitalization is the average of the daily market capitalizations of the PCT Payee over a period of time beginning 60 days before the date of the PCT and ending on the date of the PCT. The daily market capitalization of the PCT Payee is calculated on each day its stock is actively traded as the total number of shares outstanding multiplied by the adjusted closing price of the stock on that day. The adjusted closing price is the daily closing price of the stock, after adjustments for stock-based transactions (dividends and stock splits) and other pending corporate (combination and spin-off) restructuring transactions for which reliable arm's length adjustments can be made.

(iv) Adjusted average market capitalization. The adjusted average market capitalization is the average market capitalization of the PCT Payee increased by the value of the PCT Payee's liabilities on the date of the PCT and decreased by the value on such date of the PCT Payee's tangible property and of any other resources, capabilities, or rights of the PCT Payee not covered by a PCT or group of PCTs.

(v) Best method analysis considerations. The comparability and reliability considerations stated in § 1.482-4(c)(2) apply. Consistent with those considerations, the reliability of applying the comparable uncontrolled transaction method using the adjusted market capitalization of a company as a measure of the arm's length charge for the PCT Payment normally is reduced if --

(vi) Examples. The following examples illustrate the principles of this paragraph (g)(6):

Example 1. (i) USP, a publicly traded U.S. company, and its newly incorporated wholly-owned foreign subsidiary (FS) enter into a CSA on Date 1 to develop software. At that time USP has in-process software but has no software ready for the market. Under the CSA, USP and FS will have the exclusive rights to exploit the software developed under the CSA in the United States and the rest of the world, respectively. On Date 1, USP's RAB share is 70% and FS's RAB share is 30%. USP's assembled team of researchers and its in-process software are reasonably anticipated to contribute to the development of the software under the CSA. Therefore, the rights in the research team and in-process software are platform contributions for which compensation is due from FS. Further, these rights are not reasonably anticipated to contribute to any business activity other than the CSA Activity.

(ii) On Date 1, USP had an average market capitalization of $205 million, tangible property and other assets that can be reliably valued worth $5 million, and no liabilities. Aside from those assets, USP had no assets other than its research team and in-process software. Applying the market capitalization method, the value of USP's platform contributions is $200 million ($205 million average market capitalization of USP less $5 million of tangible property and other assets). The arm's length value of the PCT Payments FS must make to USP for the platform contributions, before any adjustment on account of tax liability as described in paragraph (g)(2)(ii) of this section, is $60 million, which is the product of $200 million (the value of the platform contributions) and 30% (FS's RAB share on Date 1).

Example 2. Aggregation with make-or-sell rights. (i) The facts are the same as in Example 1, except that on Date 1 USP also has existing software ready for the market. USP separately enters into a license agreement with FS for make-or-sell rights for all existing software outside the United States. No marketing has occurred, and USP has no marketing intangibles. This license of current make-or-sell rights is a transaction governed by § 1.482-4. However, after analysis, it is determined that the arm's length PCT Payments and the arm's length payments for the make-or-sell license may be most reliably determined in the aggregate using the market capitalization method, under principles described in paragraph (g)(2)(iv) of this section, and it is further determined that those principles are most reliably implemented by computing the aggregate arm's length charge as the product of the aggregate value of the existing and in-process software and FS's RAB share on Date 1.

(ii) Applying the market capitalization method, the aggregate value of USP's platform contributions and the make-or-sell rights in its existing software is $250 million ($255 million average market capitalization of USP less $5 million of tangible property and other assets). The total arm's length value of the PCT Payments and licensing payments FS must make to USP for the platform contributions and current make-or-sell rights, before any adjustment on account of tax liability, if any, is $75 million, which is the product of $250 million (the value of the platform contributions and the make-or-sell rights) and 30% (FS's RAB share on Date 1).

Example 3. Reduced reliability. The facts are the same as in Example 1 except that USP also has significant nonroutine assets that will be used solely in a nascent business division that is unrelated to the subject of the CSA and that cannot themselves be reliably valued. Those nonroutine contributions are not platform contributions and accordingly are not required to be covered by a PCT. The reliability of using the market capitalization method to determine the value of USP's platform contributions to the CSA is significantly reduced in this case because that method would require adjusting USP's average market capitalization to account for the significant nonroutine contributions that are not required to be covered by a PCT.

(i) In general. The residual profit split method evaluates whether the allocation of combined operating profit or loss attributable to one or more platform contributions subject to a PCT is arm's length by reference to the relative value of each controlled participant's contribution to that combined operating profit or loss. The combined operating profit or loss must be derived from the most narrowly identifiable business activity (relevant business activity) of the controlled participants for which data are available that include the CSA Activity. The residual profit split method may not be used where only one controlled participant makes significant nonroutine contributions (including platform or operating contributions) to the CSA Activity. The provisions of § 1.482-6 shall apply to CSAs only to the extent provided and as modified in this paragraph (g)(7). Any other application to a CSA of a residual profit method not described in paragraphs (g)(7)(ii) and (iii) of this section will constitute an unspecified method for purposes of sections 482 and 6662(e) and the regulations under those sections.

(ii) Appropriate share of profits and losses. The relative value of each controlled participant's contribution to the success of the relevant business activity must be determined in a manner that reflects the functions performed, risks assumed, and resources employed by each participant in the relevant business activity, consistent with the best method analysis described in § 1.482-1(c) and (d). Such an allocation is intended to correspond to the division of profit or loss that would result from an arrangement between uncontrolled taxpayers, each performing functions similar to those of the various controlled participants engaged in the relevant business activity. The profit allocated to any particular controlled participant is not necessarily limited to the total operating profit of the group from the relevant business activity. For example, in a given year, one controlled participant may earn a profit while another controlled participant incurs a loss. In addition, it may not be assumed that the combined operating profit or loss from the relevant business activity should be shared equally, or in any other arbitrary proportion.

(iii) Profit split.

(iv) Best method analysis considerations.

(v) Examples. The following examples illustrate the principles of this paragraph (g)(7):

Example 1. (i) For simplicity of calculation in this Example 1, all financial flows are assumed to occur at the beginning of each period. USP, a U.S. electronic data storage company, has partially developed technology for a type of extremely small compact storage devices (nanodisks) which are expected to provide a significant increase in data storage capacity in various types of portable devices such as cell phones, MP3 players, laptop computers and digital cameras. At the same time, USP's wholly-owned subsidiary, FS, has developed significant marketing intangibles outside the United States in the form of customer lists, ongoing relations with various OEMs, and trademarks that are well recognized by consumers due to a long history of marketing successful data storage devices and other hardware used in various types of consumer electronics. At the beginning of Year 1, USP enters into a CSA with FS to develop nanodisk technologies for eventual commercial exploitation. Under the CSA, USP will have the right to exploit nanodisks in the United States, while FS will have the right to exploit nanodisks in the rest of the world. The partially developed nanodisk technologies owned by USP are reasonably anticipated to contribute to the development of commercially exploitable nanodisks and therefore the rights in the nanodisk technologies constitute platform contributions of USP for which compensation is due under PCTs. FS does not have any platform contributions for the CSA. Due to the fact that nanodisk technologies have yet to be incorporated into any commercially available product, neither USP nor FS transfers rights to make or sell current products in conjunction with the CSA.

(ii) Because only in FS's territory do both controlled participants make significant nonroutine contributions, USP and FS determine that they need to determine the relative value of their respective contributions to residual divisional profit or loss attributable to the CSA Activity only in FS's territory. FS anticipates making no nanodisk sales during the first year of the CSA in its territory with revenues in Year 2 reaching $200 million. Revenues through Year 5 are reasonably anticipated to increase by 50% per year. The annual growth rate for revenues is then expected to decline to 30% per annum in Years 6 and 7, 20% per annum in Years 8 and 9 and 10% per annum in Year 10. Revenues are then expected to decline 10% in Year 11 and 5% per annum, thereafter. The routine costs (defined here as costs other than cost contributions, routine platform and operating contributions, and nonroutine contributions) that are allocable to this revenue in calculating FS's divisional profit or loss, are anticipated to equal $40 million for the first year of the CSA and $130 for the second year and $200 and $250 million in Years 3 and 4. Total operating expenses attributable to product exploitation (including operating cost contributions) equal 52% of sales per year. FS undertakes routine distribution activities in its markets that constitute routine contributions to the relevant business activity of exploiting nanodisk technologies. USP and FS estimate that the total market return on these routine contributions will amount to 6% of the routine costs. FS expects its cost contributions to be $60 million in Year 1, rise to $100 million in Years 2 and 3, and then decline again to $60 million in Year 4. Thereafter, FS's cost contributions are expected to equal 10% of revenues.

(iii) USP and FS determine the present value of the stream of the reasonably anticipated residuals in FS's territory over the duration of the CSA Activity of the divisional profit or loss (revenues minus routine costs), minus the market returns for routine contributions, the operating cost contributions, and the cost contributions. USP and FS determine, based on the considerations discussed in paragraph (g)(2)(v) of this section, that the appropriate discount rate is 17.5% per annum. Therefore, the present value of the nonroutine residual divisional profit is $1,395 million.

(iv) After analysis, USP and FS determine that the relative value of the nanodisk technologies contributed by USP to CSA (giving effect only to its value in FS's territory) is roughly 150% of the value of FS's marketing intangibles (which only have value in FS's territory). Consequently, 60% of the nonroutine residual divisional profit is attributable to USP's platform contribution. Therefore, FS's PCT Payments should have an expected present value equal to $837 million (.6 x $1,395 million).

(v) The calculations for this Example 1 are displayed in the following table:

Example 2. (i) For simplicity of calculation in this Example 2, all financial flows are assumed to occur at the beginning of each period. USP is a U.S. automobile manufacturing company that has completed significant research on the development of diesel-electric hybrid engines that, if they could be successfully manufactured, would result in providing a significant increased fuel economy for a wide variety of motor vehicles. Successful commercialization of the diesel-electric hybrid engine will require the development of a new class of advanced battery that will be light, relatively cheap to manufacture and yet capable of holding a substantial electric charge. FS, a foreign subsidiary of USP, has completed significant research on developing lithium-ion batteries that appear likely to have the requisite characteristics. At the beginning of Year 1, USP enters into a CSA with FS to further develop diesel-electric hybrid engines and lithium-ion battery technologies for eventual commercial exploitation. Under the CSA, USP will have the right to exploit the diesel-electric hybrid engine and lithium-ion battery technologies in the United States, while FS will have the right to exploit such technologies in the rest of the world. The partially developed diesel-electric hybrid engine and lithium-ion battery technologies owned by USP and FS, respectively, are reasonably anticipated to contribute to the development of commercially exploitable automobile engines and therefore the rights in both these technologies constitute platform contributions of USP and of FS for which compensation is due under PCTs. At the time of inception of the CSA, USP owns operating intangibles in the form of self-developed marketing intangibles which have significant value in the United States, but not in the rest of the world, and that are relevant to exploiting the cost shared intangibles. Similarly, FS owns self-developed marketing intangibles which have significant value in the rest of the world, but not in the United States, and that are relevant to exploiting the cost shared intangibles. Although the new class of diesel-electric hybrid engine using lithium-ion batteries is not yet ready for commercial exploitation, components based on this technology are beginning to be incorporated in current-generation gasoline-electric hybrid engines and the rights to make and sell such products are transferred from USP to FS and vice-versa in conjunction with the inception of the CSA, following the same territorial division as in the CSA.

(ii) USP's estimated RAB share is 66.7%. During Year 1, it is anticipated that sales in USP's territory will be $1000X in Year 1. Sales in FS's territory are anticipated to be $500X. Thereafter, as revenue from the use of components in gasoline-electric hybrids is supplemented by revenues from the production of complete diesel-electric hybrid engines using lithium-ion battery technology, anticipated sales in both territories will increase rapidly at a rate of 50% per annum through Year 4. Anticipated sales are then anticipated to increase at a rate of 40% per annum for another 4 years. Sales are then anticipated to increase at a rate of 30% per annum through Year 10. Thereafter, sales are anticipated to decrease at a rate of 5% per annum for the foreseeable future as new automotive drive-train technologies displace diesel-electric hybrid engines and lithium-ion batteries. Total operating expenses attributable to product exploitation (including operating cost contributions) equal 40% of sales per year for both USP and FS. USP and FS estimate that the total market return on these routine contributions to the CSA will amount to 6% of these operating expenses. USP is expected to bear 2/3 of the total cost contributions for the foreseeable future. Cost contributions are expected to total $375X in Year 1 (of which $250X are borne by USP) and increase at a rate of 25% per annum through Year 6. In Years 7 through 10, cost contributions are expected to increase 10% a year. Thereafter, cost contributions are expected to decrease by 5% a year for the foreseeable future.

(iii) USP and FS determine the present value of the stream of FS's reasonably anticipated residual divisional profit, which is the stream of FS's reasonably anticipated divisional profit or loss, minus the market returns for routine contributions, minus operating cost contributions, minus cost contributions. USP and FS determine, based on the considerations discussed in paragraph (g)(2)(v) of this section, that the appropriate discount rate is 12% per year. Therefore, the present value of the nonroutine residual divisional profit in USP's territory is $41,727X and in CFC's territory is $20,864X.

(iv) After analysis, USP and FS determine that, in the United States the relative value of the technologies contributed by USP and FS to the CSA and of the operating intangibles used by USP in the exploitation of the cost shared intangibles (reported as equaling 100 in total), equals: USP's platform contribution (59.5); FS's platform contribution (25.5); and USP's operating intangibles (15). Consequently, the present value of the arm's length amount of the PCT Payments that USP should pay to FS for FS's platform contribution is $10,640X (.255 x $41,727X). Similarly, USP and FS determine that, in the rest of the world, the relative value of the technologies contributed by USP and FS to the CSA and of the operating intangibles used by FS in the exploitation of the cost shared intangibles can be divided as follows: USP's platform contribution (63); FS's platform contribution (27); and FS's operating intangibles (10). Consequently, the present value of the arm's length amount of the PCT Payments that FS should pay to USP for USP's platform contribution is $13,144X (.63 x $20,864X). Therefore, FS is required to make a net payment to USP with a present value of $2,504X ($13,144X - 10,640X).

(v) The calculations for this Example 2 are displayed in the following tables:

(i) In general. The consideration under a PCT for a platform contribution may take one or a combination of both of the following forms:

Accordingly, controlled participants have flexibility to adopt a form and period of payment, provided that such form and period of payment are consistent with an arm's length charge as of the date of the PCT. See also paragraphs (h)(2)(iv) and (3) of this section.

(ii) No PCT Payor stock. PCT Payments may not be paid in shares of stock in the PCT Payor (or stock in any member of the controlled group that includes the controlled participants).

(iii) Specified form of payment.

(iv) Conversion from fixed to contingent form of payment. With regard to a conversion of a fixed present value to a contingent form of payment, see paragraphs (g)(2)(v) (Discount rate) and (vi) (Financial projections) of this section.

(i) In general. The Commissioner may make allocations to adjust the results of a CST so that the results are consistent with an arm's length result, including any allocations to make each controlled participant's IDC share, as determined under paragraph (d)(4) of this section, equal to that participant's RAB share, as determined under paragraph (e)(1) of this section. Such allocations may result from, for purposes of CST determinations, adjustments to --

(ii) Adjustments to improve the reliability of projections used to estimate RAB shares.

(iii) Timing of CST allocations. If the Commissioner makes an allocation to adjust the results of a CST, the allocation must be reflected for tax purposes in the year in which the IDCs were incurred. When a CST payment is owed by one controlled participant to another controlled participant, the Commissioner may make appropriate allocations to reflect an arm's length rate of interest for the time value of money, consistent with the provisions of § 1.482-2(a) (Loans or advances).

(i) In general. Subject to the exceptions in paragraph (i)(6)(vi) of this section, the Commissioner may make periodic adjustments for an open taxable year (the Adjustment Year) and for all subsequent taxable years for the duration of the CSA Activity with respect to all PCT Payments, if the Commissioner determines that, for a particular PCT (the Trigger PCT), a particular controlled participant that owes or owed a PCT Payment relating to that PCT (such controlled participant being referred to as the PCT Payor for purposes of this paragraph (i)(6)) has realized an Actually Experienced Return Ratio (AERR) that is outside the Periodic Return Ratio Range (PRRR). The satisfaction of the condition stated in the preceding sentence is referred to as a Periodic Trigger. See paragraphs (i)(6)(ii) through (vi) of this section regarding the PRRR, the AERR, and periodic adjustments. In determining whether to make such adjustments, the Commissioner may consider whether the outcome as adjusted more reliably reflects an arm's length result under all the relevant facts and circumstances, including any information known as of the Determination Date. The Determination Date is the date of the relevant determination by the Commissioner. The failure of the Commissioner to determine for an earlier taxable year that a PCT Payment was not arm's length will not preclude the Commissioner from making a periodic adjustment for a subsequent year. A periodic adjustment under this paragraph (i)(6) may be made without regard to whether the taxable year of the Trigger PCT or any other PCT remains open for statute of limitations purposes or whether a periodic adjustment has previously been made with respect to any PCT Payment.

(ii) PRRR. Except as provided in the next sentence, the PRRR will consist of return ratios that are not less than .667 nor more than 1.5. Alternatively, if the controlled participants have not substantially complied with the documentation requirements referenced in paragraph (k) of this section, as modified, if applicable, by paragraphs (m)(2) and (3) of this section, the PRRR will consist of return ratios that are not less than .8 nor more than 1.25.

(iii) AERR.

(iv) ADR.

(v) Determination of periodic adjustments. In the event of a Periodic Trigger, subject to paragraph (i)(6)(vi) of this section, the Commissioner may make periodic adjustments with respect to all PCT Payments between all PCT Payors and PCT Payees for the Adjustment Year and all subsequent years for the duration of the CSA Activity pursuant to the residual profit split method as provided in paragraph (g)(7) of this section, subject to the further modifications in this paragraph (i)(6)(v). A periodic adjustment may be made for a particular taxable year without regard to whether the taxable years of the Trigger PCT or other PCTs remain open for statute of limitation purposes.

(vi) Exceptions to periodic adjustments.

(vii) Examples. The following examples illustrate the rules of this paragraph (i)(6):

Example 1. (i) For simplicity of calculation in this Example 1, all financial flows are assumed to occur at the beginning of the year. At the beginning of Year 1, USP, a publicly traded U.S. company, and FS, its wholly-owned foreign subsidiary, enter into a CSA to develop new technology for cell phones. USP has a platform contribution, the rights for an in-process technology that when developed will improve the clarity of calls, for which compensation is due from FS. FS has no platform contributions to the CSA, no operating contributions, and no operating cost contributions. USP and FS agree to fixed PCT payments of $40 million in Year 1 and $10 million per year for Years 2 through 10. At the beginning of Year 1, the weighted average cost of capital of the controlled group that includes USP and FS is 15%. In Year 9, the Commissioner audits Years 5 through 7 of the CSA and considers whether any periodic adjustments should be made. USP and FS have substantially complied with the documentation requirements of paragraph (k) of this section.

(ii) FS experiences the results reported in the following table from its participation in the CSA through Year 7. In the table, all present values (PV) are reported as of the CSA Start Date, which is the same as the date of the PCT (and reflect a 15% discount rate as discussed in paragraph (iii) of this Example 1). Thus, in any year the present value of the cumulative investment is PVI and of the cumulative divisional profit or loss is PVTP. All amounts in this table and the tables that follow are reported in millions of dollars and cost contributions are referred to as "CCs" (for simplicity of calculation in this Example 1, all financial flows are assumed to occur at the beginning of the year).

(iii) Because USP is publicly traded in the United States and is a member 162 of the controlled group to which FS (the PCT Payor) belongs, for purposes of calculating the AERR for FS, the present values of its PVTP and PVI are determined using an ADR of 15%, the weighted average cost of capital of the controlled group. (It is assumed that no other rate was determined or established, under paragraph (i)(6)(iv)(B) of this section, to better reflect the relevant degree of risk.) At a 15% discount rate, the PVTP, calculated as of Year 1, and based on actual profits realized by FS through Year 7 from exploiting the new cell phone technology developed by the CSA, is $526 million. The PVI, based on FS's cost contributions and its PCT Payments, is $171 million. The AERR for FS is equal to its PVTP divided by its PVI, $526 million/$171 million, or 3.09. There is a Periodic Trigger because FS's AERR of 3.09 falls outside the PRRR of .67 to 1.5, the applicable PRRR for controlled participants complying with the documentation requirements of this section.

(iv) At the time of the Determination Date, it is determined that the first Adjustment Year in which a Periodic Trigger occurred was Year 6, when the AERR of FS was determined to be 2.20. It is also determined that for Year 6 none of the exceptions to periodic adjustments described in paragraph (i)(6)(vi) of this section applies. The Commissioner exercises its discretion under paragraph (i)(6)(i) of this section to make periodic adjustments using Year 6 as the Adjustment Year. Therefore, the arm's length PCT Payments from FS to USP shall be determined for each taxable year using the adjusted residual profit split method described in paragraphs (g)(7) and (i)(6)(v)(B) of this section. Periodic adjustments will be made for each year to the extent the PCT Payments actually made by FS differ from the PCT Payment calculation under the adjusted residual profit split method.

(v) It is determined, as of the Determination Date, that the cost shared intangibles will be exploited through Year 10. FS's return for routine contributions (determined by the Commissioner, based on the return for comparable functions undertaken by comparable uncontrolled companies, to be 8% of non-CC costs), and its actual and projected results, are described in the following table.

(vi) The periodic adjustments are calculated in a series of steps set out in paragraph (i)(6)(v)(A) of this section. First, a lump sum for the PCT Payment is determined using the adjusted residual profit split method. Under the method, based on the considerations discussed in paragraph (g)(2)(v) of this section, the appropriate discount rate is 15% per year. The nonroutine residual divisional profit or loss described in paragraph (g)(7)(iii)(B) of this section is $612 million. Further, under paragraph (g)(7)(iii)(C) of this section, the entire nonroutine residual divisional profit constitutes the PCT Payment because only USP has nonroutine contributions.

(vii) In step two, the first step result ($612 million) is converted into a level royalty rate based on the reasonably anticipated divisional profit or losses of the CSA Activity, the PV of which is reported in the table above (net PV of divisional profit or loss for Years 1 through 10 is $927 million). Consequently, the step two result is a level royalty rate of 66.0% ($612/$927) of the divisional profit in Years 1 through 10.

(viii) In step three, the Commissioner calculates the PCT Payments due through Year 6 by applying the step two royalty rate to the actual divisional profits for each year and then determines the aggregate PV of these PCT Payments as of the CSA Start Date ($224 million as reported in the following table). In step four, the PCT Payments actually made through Year 6 are similarly converted to PV as of the CSA Start Date ($74 million) and subtracted from the amount determined in step three ($224 million - $74 million = $150 million). That difference of $150 million, representing a net PV as of the CSA Start Date, is then converted to a nominal amount, as of the Adjustment Year, of equivalent present value (again using a discount rate of 15%). That nominal amount is $302 million (not shown in the table), and is the periodic adjustment in Year 6.

(ix) Under step five, the royalties due from FS to USP for Year 7 (the year after the Adjustment Year) through Year 9 (the year including the Determination Date) are determined. (These determinations are made for Years 8 and 9 after the divisional profit for those years becomes available.) For each year, the periodic adjustment is a PCT Payment due in addition to the $10 million PCT Payment that must otherwise be paid under the CSA as described in paragraph (i) of this Example 1. That periodic adjustment is calculated as the product of the step two royalty rate and the divisional profit, minus the $10 million that was otherwise paid for that year. The calculations are shown in the following table:

(x) Under step six, the periodic adjustment for Year 10 (the only exploitation year after the year containing the Determination Date) will be determined by applying the step two royalty rate to the divisional profit. This periodic adjustment is a PCT Payment payable from FS to USP, and is in lieu of the $10 payment otherwise due. The calculations are shown in the following table, based on a divisional profit of $391 million. USP and FS experienced the following results in Year 10.

Example 2. The facts are the same as in paragraphs (i) through (iii) of Example 1. At the time of the Determination Date, it is determined that the first Adjustment Year in which a Periodic Trigger occurred was Year 6, when the AERR of FS was determined to be 2.73. Upon further investigation as to what may have caused the high return in FS's market, the Commissioner learns that, in Years 4 through 6, USP's leading competitors experienced severe, unforeseen disruptions in their supply chains resulting in a significant increase in USP's and FS's market share for cell phones. Further analysis determines that without this unforeseen occurrence the Periodic Trigger would not have occurred. Based on paragraph (i)(6)(vi)(A)(2) of this section, the Commissioner determines to his satisfaction that no adjustments are warranted.

Example 3. (i) USP, a U.S. corporation, and its wholly-owned foreign subsidiaries FS1, FS2, and FS3 enter into a CSA at the start of Year 1 to develop version 2.0 of a computer program. USP makes a platform contribution, version 1.0 of the program (upon which version 2.0 will be based), for which compensation is due from FS1, FS2, and FS3. None of the foreign subsidiaries makes any platform contributions.

(ii) In Year 6, the Commissioner audits Years 3 through 5 of the CSA and considers whether any periodic adjustments should be made. At the time of the Determination Date, the Commissioner determines that the first Adjustment Year in which a Periodic Trigger occurred was Year 3, and further determines that none of the exceptions to periodic adjustments described in paragraph (i)(6)(vi) of this section applies. The Commissioner exercises his discretion under paragraph (i)(6)(i) of this section to make periodic adjustments using Year 3 as the Adjustment Year. Therefore, the arm's length PCT Payments from FS1, FS2, and FS3 to USP shall be determined using the adjusted residual profit split method described in paragraphs (g)(7)(v)(B) and (i)(6)(v)(B) of this section. Periodic adjustments will be made for each year to the extent the PCT Payments actually made by FS1, FS2, and FS3 differ from the PCT Payment calculation under the adjusted residual profit split method.

(iii) The periodic adjustments are calculated in a series of steps set out in paragraph (i)(6)(v)(A) of this section. First, a lump sum for the PCT Payments is determined using the adjusted residual profit split method. The following results are calculated (based on actual results for years for which actual results are available and projected results for all years thereafter) in order to apply the adjusted residual profit split method (it is determined that the cost shared intangibles will be exploited through Year 7, so the results reported in the following table are cumulative values through Year 7):

Because only USP had nonroutine contributions, under paragraph (g)(7)(iii)(C) of this section, the entire nonroutine residual divisional profit constitutes the PCT Payment owed to USP. Therefore, the present values (as of the CSA Start Date) of the PCT Payments owed are as follows:

PCT Payment owed from FS1 to USP: $314 million

PCT Payment owed from FS2 to USP: $159 million

PCT Payment owed from FS3 to USP: $295 million

Pursuant to paragraph (i)(6)(v)(A) of this section, the steps in paragraphs (i)(6)(v)(A)(2) through (7) of this section are performed separately for the PCT Payments that are owed to USP by each of FS1, FS2, and FS3.

(iv) First, the steps are performed with respect to FS1. In step two, the first step result ($314 million) is converted into a level royalty rate based on FS1's reasonably anticipated divisional profits or losses through Year 7 (the PV of which is $667 million). Consequently, the step two result is a level royalty rate of 47.1% ($314/$667) of the divisional profits in Years 1 through 7. In step three, the Commissioner calculates the PCT Payments due through Year 3 (the Adjustment Year) by applying the step two royalty rate (47.1%) to FS1's actual divisional profits for each year up to and including Year 3 and then determining the aggregate PV of these PCT Payments as of Year 3. In step four, the PCT Payments actually made by FS1 to USP through Year 3 are similarly converted to a PV as of Year 3 and subtracted from the amount determined in step three. That difference is the periodic adjustment in Year 3 with respect to the PCT Payments made for Years 1 through 3 from FS1 to USP. Under step five, the royalties due from FS1 to USP for Year 4 (the year after the Adjustment Year) through Year 6 (the year including the Determination Date) are determined. The periodic adjustment for each of these years is calculated as the product of the step two royalty rate and the divisional profit for that year, minus any actual PCT Payment made by FS1 to USP in that year. The periodic adjustment for each such year is a PCT Payment due in addition to the PCT Payment from FS1 to USP that was already made under the CSA. Under step six, the periodic adjustment for Year 7 (the only exploitation year after the year containing the Determination Date) will be determined by applying the step two royalty rate to FS1's divisional profit for that year. This periodic adjustment for Year 7 is a PCT Payment payable from FS1 to USP and is in lieu of any PCT Payment from FS1 to USP otherwise due.

(v) Next, the steps in paragraphs (i)(6)(v)(A)(2) through (7) of this section are performed with respect to FS2. In step two, the first step result ($159 million) is converted into a level royalty rate based on FS2's reasonably anticipated divisional profits or losses through Year 7 (the PV of which is $271 million). Consequently, the step two result is a level royalty rate of 58.7% ($159/$271) of the divisional profits in Years 1 through 7. In step three, the Commissioner calculates the PCT Payments due through Year 3 (the Adjustment Year) by applying the step two royalty rate (58.7%) to FS2's actual divisional profits for each year up to and including Year 3 and then determining the aggregate PV of these PCT Payments as of Year 3. In step four, the PCT Payments actually made by FS2 to USP through Year 3 are similarly converted to a PV as of Year 3 and subtracted from the amount determined in step three. That difference is the periodic adjustment in Year 3 with respect to the PCT Payments made for Years 1 through 3 from FS2 to USP. Under step five, the royalties due from FS2 to USP for Year 4 (the year after the Adjustment Year) through Year 6 (the year including the Determination Date) are determined. The periodic adjustment for each of these years is calculated as the product of the step two royalty rate and the divisional profit for that year, minus any actual PCT Payment made by FS2 to USP in that year. The periodic adjustment for each such year is a PCT Payment due in addition to the PCT Payment from FS2 to USP that was already made under the CSA. Under step six, the periodic adjustment for Year 7 (the only exploitation year after the year containing the Determination Date) will be determined by applying the step two royalty rate to FS2's divisional profit for that year. This periodic adjustment for Year 7 is a PCT Payment payable from FS2 to USP and is in lieu of any PCT Payment from FS2 to USP otherwise due.

(vi) Finally, the steps in paragraphs (i)(6)(v)(A)(2) through (7) of this section are performed with respect to FS3. In step two, the first step result ($295 million) is converted into a level royalty rate based on FS3's reasonably anticipated divisional profits or losses through Year 7 (the PV of which is $592 million). Consequently, the step two result is a level royalty rate of 49.8% ($295/$592) of the divisional profits in Years 1 through 7. In step three, the Commissioner calculates the PCT Payments due through Year 3 (the Adjustment Year) by applying the step two royalty rate (49.8%) to FS3's actual divisional profits for each year up to and including Year 3 and then determining the aggregate PV of these PCT Payments as of Year 3. In step four, the PCT Payments actually made by FS3 to USP through Year 3 are similarly converted to a PV as of Year 3 and subtracted from the amount determined in step three. That difference is the periodic adjustment in Year 3 with respect to the PCT Payments made for Years 1 through 3 from FS3 to USP. Under step five, the royalties due from FS3 to USP for Year 4 (the year after the Adjustment Year) through Year 6 (the year including the Determination Date) are determined. The periodic adjustment for each of these years is calculated as the product of the step two royalty rate and the divisional profit for that year, minus any actual PCT Payment made by FS3 to USP in that year. The periodic adjustment for each such year is a PCT Payment due in addition to the PCT Payment from FS3 to USP that was already made under the CSA. Under step six, the periodic adjustment for Year 7 (the only exploitation year after the year containing the Determination Date) will be determined by applying the step two royalty rate to FS3's divisional profit for that year. This periodic adjustment for Year 7 is a PCT Payment payable from FS3 to USP and is in lieu of any PCT Payment from FS3 to USP otherwise due.

(i) In general. For purposes of this section --

(ii) Examples. The following examples illustrate certain definitions in paragraph (j)(1)(i) of this section:

Example 1. Controlled participant. Foreign Parent (FP) is a foreign corporation engaged in the extraction of a natural resource. FP has a U.S. subsidiary (USS) to which FP sells supplies of this resource for sale in the United States. FP enters into a CSA with USS to develop a new machine to extract the natural resource. The machine uses a new extraction process that will be patented in the United States and in other countries. The CSA provides that USS will receive the rights to exploit the machine in the extraction of the natural resource in the United States, and FP will receive the rights in the rest of the world. This resource does not, however, exist in the United States. Despite the fact that USS has received the right to exploit this process in the United States, USS is not a controlled participant because it will not derive a benefit from exploiting the intangible developed under the CSA.

Example 2. Controlled participants. (i) U.S. Parent (USP), one foreign subsidiary (FS), and a second foreign subsidiary constituting the group's research arm (R+D) enter into a CSA to develop manufacturing intangibles for a new product line A. USP and FS are assigned the exclusive rights to exploit the intangibles respectively in the United States and the rest of the world, where each presently manufactures and sells various existing product lines. R+D is not assigned any rights to exploit the intangibles. R+D's activity consists solely in carrying out research for the group. It is reliably projected that the RAB shares of USP and FS will be 66 2/3% and 33 1/3%, respectively, and the parties' agreement provides that USP and FS will reimburse 66 2/3% and 33 1/3%, respectively, of the IDCs incurred by R+D with respect to the new intangible.

(ii) R+D does not qualify as a controlled participant within the meaning of paragraph (j)(1)(i) of this section, because it will not derive any benefits from exploiting cost shared intangibles. Therefore, R+D is treated as a service provider for purposes of this section and must receive arm's length consideration for the assistance it is deemed to provide to USP and FS, under the rules of paragraph (a)(3) of this section and §§ 1.482-4(f)(3)(iii) and (4), and 1.482-9, as appropriate. Such consideration must be treated as IDCs incurred by USP and FS in proportion to their RAB shares (that is, 66 2/3% and 33 1/3%, respectively). R+D will not be considered to bear any share of the IDCs under the arrangement.

Example 3. Cost shared intangible, reasonably anticipated cost shared intangible. U.S. Parent (USP) has developed and currently exploits an antihistamine, XY, which is manufactured in tablet form. USP enters into a CSA with its wholly-owned foreign subsidiary (FS) to develop XYZ, a new improved version of XY that will be manufactured as a nasal spray. Work under the CSA is fully devoted to developing XYZ, and XYZ is developed. During the development period, XYZ is a reasonably anticipated cost shared intangible under the CSA. Once developed, XYZ is a cost shared intangible under the CSA.

Example 4. Cost shared intangible. The facts are the same as in Example 3, except that in the course of developing XYZ, the controlled participants by accident discover ABC, a cure for disease D. ABC is a cost shared intangible under the CSA.

Example 5. Reasonably anticipated benefits. Controlled parties A and B enter into a cost sharing arrangement to develop product and process intangibles for an already existing Product P. Without such intangibles, A and B would each reasonably anticipate revenue, in present value terms, of $100M from sales of Product P until it became obsolete. With the intangibles, A and B each reasonably anticipate selling the same number of units each year, but reasonably anticipate that the price will be higher. Because the particular product intangible is more highly regarded in A's market, A reasonably anticipates an increase of $20M in present value revenue from the product intangible, while B reasonably anticipates only an increase of $10M. Further, A and B each reasonably anticipate spending an extra $5M present value in production costs to include the feature embodying the product intangible. Finally, A and B each reasonably anticipate saving $2M present value in production costs by using the process intangible. A and B reasonably anticipate no other economic effects from exploiting the cost shared intangibles. A's reasonably anticipated benefits from exploiting the cost shared intangibles equal its reasonably anticipated increase in revenue ($20M) plus its reasonably anticipated cost savings ($2M) minus its reasonably anticipated increased costs ($5M), which equals $17M. Similarly, B's reasonably anticipated benefits from exploiting the cost shared intangibles equal its reasonably anticipated increase in revenue ($10M) plus its reasonably anticipated cost savings ($2M) minus its reasonably anticipated increased costs ($5M), which equals $7M. Thus A's reasonably anticipated benefits are $17M and B's reasonably anticipated benefits are $7M.

(i) Consolidated group. For purposes of this section, all members of the same consolidated group shall be treated as one taxpayer. For these purposes, the term consolidated group means all members of a group of controlled entities created or organized within a single country and subjected to an income tax by such country on the basis of their combined income.

(ii) Trade or business. A participant that is a foreign corporation or nonresident alien individual will not be treated as engaged in a trade or business within the United States solely by reason of its participation in a CSA. See generally § 1.864-2(a).

(iii) Partnership. A CSA, or an arrangement to which the Commissioner applies the rules of this section, will not be treated as a partnership to which the rules of subchapter K of the Internal Revenue Code apply. See § 301.7701-1(c) of this chapter.

(i) CST Payments. CST Payments generally will be considered the payor's costs of developing intangibles at the location where such development is conducted. For these purposes, IDCs borne directly by a controlled participant that are deductible are deemed to be reduced to the extent of any CST Payments owed to it by other controlled participants pursuant to the CSA. Each cost sharing payment received by a payee will be treated as coming pro rata from payments made by all payors and will be applied pro rata against the deductions for the taxable year that the payee is allowed in connection with the IDCs. Payments received in excess of such deductions will be treated as in consideration for use of the land and tangible property furnished for purposes of the CSA by the payee. For purposes of the research credit determined under section 41, CST Payments among controlled participants will be treated as provided for intra-group transactions in § 1.41-6(i). Any payment made or received by a taxpayer pursuant to an arrangement that the Commissioner determines not to be a CSA will be subject to the provisions of §§ 1.482-1 through 1.482-6 and 1.482-9. Any payment that in substance constitutes a cost sharing payment will be treated as such for purposes of this section, regardless of its characterization under foreign law.

(ii) PCT Payments. A PCT Payor's payment required under paragraph (b)(1)(ii) of this section is deemed to be reduced to the extent of any payments owed to it under such paragraph from other controlled participants. Each PCT Payment received by a PCT Payee will be treated as coming pro rata out of payments made by all PCT Payors. PCT Payments will be characterized consistently with the designation of the type of transaction pursuant to paragraphs (c)(3) and (k)(2)(ii)(H) of this section. Depending on such designation, such payments will be treated as either consideration for a transfer of an interest in intangible property or for services.

(iii) Examples. The following examples illustrate this paragraph (j)(3):

Example 1. U.S. Parent (USP) and its wholly owned Foreign Subsidiary (FS) form a CSA to develop a miniature widget, the Small R. Based on RAB shares, USP agrees to bear 40% and FS to bear 60% of the costs incurred during the term of the agreement. The principal IDCs are operating costs incurred by FS in Country Z of 100X annually, and costs incurred by USP in the United States also of 100X annually. Of the total costs of 200X, USP's share is 80X and FS's share is 120X so that FS must make a payment to USP of 20X. The payment will be treated as a reimbursement of 20X of USP's costs in the United States. Accordingly, USP's Form 1120 will reflect an 80X deduction on account of activities performed in the United States for purposes of allocation and apportionment of the deduction to source. The Form 5471 "Information Return of U.S. Persons With Respect to Certain Foreign Corporations" for FS will reflect a 100X deduction on account of activities performed in Country Z and a 20X deduction on account of activities performed in the United States.

Example 2. The facts are the same as in Example 1, except that the 100X of costs borne by USP consist of 5X of costs incurred by USP in the United States and 95X of arm's length rental charge, as described in paragraph (d)(1)(iii) of this section, for the use of a facility in the United States. The depreciation deduction attributable to the U.S. facility is 7X. The 20X net payment by FS to USP will first be applied in reduction pro rata of the 5X deduction for costs and the 7X depreciation deduction attributable to the U.S. facility. The 8X remainder will be treated as rent for the U.S. facility.

Example 3. (i) Four members (A, B, C, and D) of a controlled group form a CSA to develop the next generation technology for their business. Based on RAB shares, the participants agree to bear shares of the costs incurred during the term of the agreement in the following percentages: A 40%; B 15%; C 25%; and D 20%. The arm's length values of the platform contributions they respectively own are in the following amounts for the taxable year: A 80X; B 40X; C 30X; and D 30X. The provisional (before offsets) and final PCT Payments among A, B, C, and D are shown in the table as follows: (All amounts stated in X's)

(ii) The first row/first column shows A's provisional PCT Payment equal to the product of 100X (sum of 40X, 30X, and 30X) and A's RAB share of 40%. The second row/first column shows A's provisional PCT receipts equal to the sum of the products of 80X and B's, C's, and D's RAB shares (15%, 25%, and 20%, respectively). The other entries in the first two rows of the table are similarly computed. The last row shows the final PCT receipts/payments after offsets. Thus, for the taxable year, A and B are treated as receiving the 8X and 13X, respectively, pro rata out of payments by C and D of 15X and 6X, respectively.

(i) In general. A CSA must be recorded in writing in a contract that is contemporaneous with the formation (and any revision) of the CSA and that includes the contractual provisions described in this paragraph (k)(1).

(ii) Contractual provisions. The written contract described in this paragraph (k)(1) must include provisions that --

(iii) Meaning of contemporaneous.

(iv) Interpretation of contractual provisions.

(i) In general. The controlled participants must timely update and maintain sufficient documentation to establish that the participants have met the CSA contractual requirements of paragraph (k)(1) of this section and the additional CSA documentation requirements of this paragraph (k)(2).

(ii) Additional CSA documentation requirements. The controlled participants to a CSA must timely update and maintain documentation sufficient to --

(iii) Coordination rules and production of documents.

(i) In general. The controlled participants must maintain books and records (and related or underlying data and information) that are sufficient to --

(ii) Reliance on financial accounting. For purposes of this section, the controlled participants may not rely solely upon financial accounting to establish satisfaction of the accounting requirements of this paragraph (k)(3). Rather, the method of accounting must clearly reflect income. Thor Power Tools Co. v. Commissioner, 439 U.S. 522 (1979).

(i) CSA Statement. Each controlled participant must file with the Internal Revenue Service, in the manner described in this paragraph (k)(4), a "Statement of Controlled Participant to § 1.482-7 Cost Sharing Arrangement" (CSA Statement) that complies with the requirements of this paragraph (k)(4).

(ii) Content of CSA Statement. The CSA Statement of each controlled participant must --

(iii) Time for filing CSA Statement.

(iv) Examples. The following examples illustrate this paragraph (k)(4). In each example, Companies A and B are members of the same controlled group.

Example 1. A and B, both of which file U.S. tax returns, agree to share the costs of developing a new chemical formula in accordance with the provisions of this section. On March 30, Year 1, A and B record their agreement in a written contract styled, "Cost Sharing Agreement." The contract applies by its terms to IDCs occurring after March 1, Year 1. The first IDCs to which the CSA applies occurred on March 15, Year 1. To comply with paragraph (k)(4)(iii)(A) of this section, A and B individually must file separate CSA Statements no later than 90 days after March 15, Year 1 (June 13, Year 1). Further, to comply with paragraph (k)(4)(iii)(B) of this section, A and B must attach copies of their respective CSA Statements to their respective Year 1 U.S. income tax returns.

Example 2. The facts are the same as in Example 1, except that a year has passed and C, which files a U.S. tax return, joined the CSA on May 9, Year 2. To comply with the annual filing requirement described in paragraph (k)(4)(iii)(B) of this section, A and B must each attach copies of their respective CSA Statements (as filed for Year 1) to their respective Year 2 income tax returns, along with a schedule updated appropriately to reflect the changes in information described in paragraph (k)(4)(ii) of this section resulting from the addition of C to the CSA. To comply with both the 90-day rule described in paragraph (k)(4)(iii)(A) of this section and the annual filing requirement described in paragraph (k)(4)(iii)(B) of this section, C must file a CSA Statement no later than 90 days after May 9, Year 2 (August 7, Year 2), and must attach a copy of such CSA Statement to its Year 2 income tax return.

(i) CSTs and PCTs occurring prior to January 5, 2009, shall be subject to the provisions of former § 1.482-7 rather than this section.

(ii) Except to the extent provided in paragraph (m)(3) of this section, PCTs that occur under a CSA that was a qualified cost sharing arrangement under the provisions of former § 1.482-7 and remained in effect on January 5, 2009, shall be subject to the periodic adjustment rules of § 1.482-4(f)(2) rather than the rules of paragraph (i)(6) of this section.

(iv) Paragraph (k)(1)(ii)(D) of this section shall not apply.

(v) Paragraphs (k)(1)(ii)(H) and (I) of this section shall be construed as applying only to transactions entered into on or after January 5, 2009.

(vi) The deadline for recordation of the revised written contractual agreement pursuant to paragraph (k)(1)(iii) of this section shall be no later than July 6, 2009.

(vii) Paragraphs (k)(2)(ii)(G) through (J) of this section shall be construed as applying only with reference to PCTs entered into on or after January 5, 2009.

(viii) Paragraph (k)(4)(iii)(A) of this section shall be construed as requiring a CSA Statement with respect to the revised written contractual agreement described in paragraph (m)(2)(vi) of this section no later than September 2, 2009.

(ix) Paragraph (k)(4)(iii)(B) of this section shall be construed as only applying for taxable years ending after the filing of the CSA Statement described in paragraph (m)(2)(viii) of this section.
