Sec. 1.103-8 Interest on bonds to finance certain exempt facilities.

(i) Under section 103(b)(4) , interest paid on an issue of obligations issued by a State or local governmental unit (as defined in section 1.103-1 ) is not includable in gross income if substantially all of the proceeds of such issue is to be used to provide one or more of the exempt facilities listed in subparagraphs (A) through (J) of section 103(b)(4) and in this section. However, interest on an obligation of such issue is includable in gross income if the obligation is held by a substantial user or a related person (as described in section 103(b)(13) and section 1.103-11 ). If substantially all of the proceeds of a bond issue is to be used to provide such exempt facilities, the debt obligations are treated as obligations described in section 103(a)(1) and section 1.103-1 even though such obligations are industrial development bonds as defined in section 103(b)(2) and section 1.103-7 . Substantially all of the proceeds of an issue of governmental obligations are used to provide an exempt facility if 90 percent or more of such proceeds are so used. For purposes of this "substantially all" test, two rules apply. First, proceeds are reduced by amounts properly allocable on a pro rata basis between providing the exempt facility and other uses of the proceeds. Second, amounts used to provide an exempt facility include amounts paid or incurred which are chargeable to the facility's capital account or would be so chargeable either with a proper election by a taxpayer (for example, under section 266 ) or but for a proper election by a taxpayer to deduct such amounts. In the event the amount payable with respect to an issue during each annual period over its term is less than the amount of interest accruing thereon in such period, e.g., in the case of an issue sold by the issuer for less than its face amount, see paragraph (a)(6) of this section to determine the amount of proceeds of the issue.

(ii) The provisions of subdivision (i) of this subparagraph shall also apply to an issue of obligations substantially all of the proceeds of which is to be used to provide exempt facilities described in this section and for either or both of the following purposes: (a) To acquire or develop land as the site for an industrial park described in section 103(b)(5) and section 1.103-9, (b) to provide facilities to be used by an exempt person.

(iii) Section 103(b)(4) only becomes applicable where the bond issue meets both the trade or business and the security interest tests so that obligations are industrial development bonds within the meaning of section 103(b)(2). For rules as to exempt facilities including property functionally related and subordinate to such facilities, see subparagraph (3) of this paragraph. For rules with respect to the ultimate use of proceeds of obligations, see subparagraph (4) of this paragraph. For rules which limit the application of the provisions of this section see subparagraph (5) of this paragraph. For the interrelationship of the rules provided in this section and the exemption for certain small issues provided in section 103(b)(6), see section 1.103-10.

(i) A facility qualifies under this section only to the extent that there is a valid reimbursement allocation under section 1.150-2 with respect to expenditures that are incurred before the issue date of the bonds to provide the facility and that are to be paid with the proceeds of the issue. In addition, if the original use of the facility begins before the issue date of the bonds, the facility does not qualify under this section if any person that was a substantial user of the facility at any time during the 5-year period before the issue date or any related person to that user receives (directly or indirectly) 5 percent or more of the proceeds of the issue for the user's interest in the facility and is a substantial user of the facility at any time during the 5-year period after the issue date, unless --

(ii) A facility, the original use of which commences (or the acquisition of which occurs) on or after the issue date of bonds to provide that facility, qualifies under this section only to the extent that an official intent for the facility is adopted under section 1.150-2 by the issuer of the bonds within 60 days after the commencement of the construction, reconstruction, or acquisition of that facility. Temporary construction or other financing of a facility prior to the issuance of the bonds to provide that facility will not cause that facility to be one that does not qualify under this paragraph (a)(5)(ii).

(iii) For purposes of paragraph (a)(5)(i) of this section, substantial user has the meaning used in section 147(a)(1), related person has the meaning used in section 144(a)(3), and a user that is a governmental unit within the meaning of section 1.103-1 is disregarded.

(iv) Except to the extent provided in sections 1.142-4(d), 1.148-11A(i), and 1.150-2(j), this paragraph (a)(5) applies to bonds issued after June 30, 1993, and sold before July 8, 1997. See section 1.142-4(d) for rules relating to bonds sold on or after July 8, 1997.

(i) Except as otherwise provided in paragraph (a)(7) of this section, the proceeds of any issue of obligations sold by the issuer after June 4, 1982, shall include any imputed proceeds of the issue. The imputed proceeds of an issue equal the sum of the amounts of imputed proceeds for each annual period (hereinafter, bond year) over the term of the issue.

(ii) The amount of imputed proceeds for a bond year equals--

(iii) Interest will be deemed to accrue with respect to an obligation on an amount that, as of the commencement of that year, is equal to the sum of--

(i) There are no imputed proceeds with respect to an obligation if--

At the option of the issuer, any obligation described in the preceding sentence may be disregarded in computing the imputed proceeds of the issue. Payments with respect to such obligations are also disregarded in determining the amount payable with respect to the issue in that bond year. If each obligation which is part of an issue is described in this subdivision (i), there are no imputed proceeds with respect to the issue.

(ii) If the actual rate at which interest is to accrue over the term of an obligation is indeterminable at the date of issue then, in computing the yield of the obligation for purposes of this paragraph, such rate shall be determined as if the conditions as of the date of issue will not change over the term of the obligation. Thus, for example, if interest on an obligation is to be paid semiannually at a rate equal to 80 percent of the yield on six month Treasury bills at the most recent public sale immediately prior to the corresponding interest payment date and the yield on six month Treasury bills sold immediately preceding the issue date is 10 percent, then the six month Treasury bill rate is deemed to be a constant 10 percent for purposes of determining the amount of imputed proceeds of the issue. Therefore, all interest payments on the obligation would be deemed to be made at a rate of 8 percent.

Example 1. State A issues its bonds and plans to use substantially all of the proceeds from such bond issue to purchase land and build a facility which will be used for one of the purposes described in section 103(b) (4) and this section. The arrangement provides that (1) A will issue bonds with a face amount of $21 million and with all accrued interest payable annually, the proceeds of which (after deducting bond election costs, costs of publishing notices, attorneys' fees, printing costs, trustees' fees for fiscal agents, and similar expenses) will be $20 million; (2) $18 million of the proceeds of the bond issue will be used to purchase land and to construct such facility; (3) $2 million of the proceeds will be used for an unrelated facility which will be used by X, a nonexempt person, in a separate trade or business and for a purpose not described in section 103(b) (4) or (5); (4) X will rent both facilities for 20 years at an annual rental equal to the amount necessary to amortize the principal and pay the interest annually on the outstanding bonds; and (5) such payments by X and the facilities will be the security for the bonds. On these facts, substantially all of the proceeds will be used in connection with an exempt facility described in section 103(b)(4) and this section. Accordingly, section 103(b)(1) does not apply to the bonds unless such bonds are thereafter held by a person who is a substantial user of the facilities or a related person within the meaning of section 103(b)(13) and section 1.103-11 .

Example 2. On July 1, 1982, State B sells an issue of its obligations to an underwriter in anticipation of a public offering. The initial offering price is $18,627,639.69 of which $17,000,000 is to be used to construct a pollution control facility described in section 103(b)(4)(F). X Corporation, a nonexempt person, is to use the facility and, in exchange, is obligated to pay an amount equal to the face amount of the issue when it becomes due. The obligations are issued on August 1, 1982. The face amount of the issue is $30,000,000. The issue is a term issue with all obligations maturing on August 1, 1987. The issue bears no stated rate of interest; there are no interest coupons on the obligations. The bonds are industrial development bonds with a yield (based upon annual compounding) of ten percent. Based on these facts, the amount of imputed proceeds with respect to the issue is determined as follows:

Therefore, proceeds of the issue equal $27,272,727.27 less issuance costs. Substantially all of the bond proceeds are not used to provide an exempt facility, and section 103(b)(1) applies to the issue.

Example 3. The facts are the same as example (2) except that the issue has a face amount and purchase price of $18,500,000. The issue also provides for one payment in addition to the redemption payment, in the amount of $10,267,668 payable on or after August 1, 1986, one year before maturity. Section 103(b)(1) applies to the issue.

Example 4. On July 1, 1982, City E sells an issue of industrial development bonds to provide for a convention facility, as described in section 103(b)(4)(C). Assume that the bonds are issued on that date as well. The issue has a face amount of $15,240,000 and a purchase price of $11,929,382.53. The estimated cost of the facility is $11,000,000. The bonds are "zero coupon" bonds, i.e., there are no interest coupons. Each series is initially offered for less than 95 percent of its face amount. The issue matures serially over a five year period, with each series being allocated a part of the purchase price of the issue. The following chart indicates the purchase price and yield for each series and debt service for the issue:

* This column (interest Accruing on the issue) contains the sums of the interest that accrues on each series in each bond year. The amount of interest accruing on the issue is computed by adding the amount of interest accruing on each series outstanding for that bond year (the bottom number in the line for each bond year). The amount of interest annually accruing on each series also is added to the purchase price of the series to determine the amount of interest accruing in subsequent years, inasmuch as there are no payments with respect to the outstanding series prior to maturity. Thus, the "principal" amount, of the top of the two numbers given in such line for each bond year, is the purchase price allocable to that series plus the amount of interest that accrued on that series in prior years.

There are no imputed proceeds because the amount payable on the issue in each bond year exceeds the total amount of interest accruing on the issue during such bond year. Section 103(b)(1) does not apply to the bonds unless such bonds are held by a person who is a substantial user of the facility or a related person within the meaning of section 103(b)(13) and section 1.103-11 .

Example 5. On July 1, 1982, City C issues industrial development bonds in the face amount of $30 million to construct a sports facility described in section 103(b)(4)(B) to be leased to D, a nonexempt person, with payments on the bonds secured by the lease. C receives $30 million in exchange for the bonds which will be used to provide the facility. The bonds mature on July 1, 2002. Each bond provides for an annual interest payment equal to ten percent of the face amount of the bond, with the last payment thereon (on July 1, 2002) including a return of the principal amount of the bond. The proceeds of the issue are $30 million. Section 103(b)(1) does not apply to the bonds unless such bonds are held by a person who is a substantial user of the facility or a related person within the meaning of section 103(b)(13) and section 1.103-11.

Example 6. The facts are the same as example (5) except that each bond provides for an annual interest payment equal to nine percent of its face amount and is sold with the option to tender the bond to D for purchase at par 5 years after the sale date of July 1, 1982 (i.e., the bonds are sold with a "put" option). Such bonds also provide a put option annually thereafter. There are no imputed proceeds (without regard to section 1.103-8(a)(7)), and the result is the same as example (5).

Example 7. On July 1, 1982, City F sells an issue of industrial development bonds in the face amount of $20 million to acquire a parking facility as described in section 103(b)(4)(D). The estimated cost of the facility is $17,800,000. The issue is issued on the same date and will mature serially over the following ten years. Each bond that is part of the issue bears annual interest coupons, each of which is in an amount equal to ten percent of the face amount of the bond. Each maturity has a face amount of $2,000,000. The issue is initially offered to the public for $19,700,000, allocable to each maturity as follows:

Based on the foregoing issue proceeds equal $19,700,000 less issuance costs. There are no imputed proceeds with respect to this issue inasmuch as each bond pays interest at a constant rate in each bond year and the purchase price of each bond is at least 95 percent of its face amount. Substantially all of the proceeds are to be used to provide the exempt facility. Accordingly, section 103(b)(1) does not apply to the bonds unless such bonds are thereafter held by a person who is a substantial user of the facility or a related person within the meaning of section 103(b)(13) and section 1.103-11 .

(i) In general.

A residential rental project is a building or structure, together with any functionally related and subordinate facilities, containing one or more similarly constructed units--

(ii) Multiple buildings.

(iii) Functionally related and subordinate facilities.

Under paragraph (a)(3) of this section, facilities that are functionally related and subordinate to residential rental projects include facilities for use by the tenants, for example, swimming pools, other recreational facilities, parking areas, and other facilities which are reasonably required for the project, for example, heating and cooling equipment, trash disposal equipment or units for resident managers or maintenance personnel.

(iv) Owner-occupied residences.

For purposes of section 103 (b)(4)(A) and this paragraph (b), the term "residential rental project" does not include any building or structure which contains fewer than five units, one unit of which is occupied by an owner of the units.

(i) Rental requirement.

Once available for occupancy, each unit (as defined in paragraph (b)(8)(i) of this section) in a residential rental project must be rented or available for rental on a continuous basis during the longer of--

(ii) Low or moderate income occupancy requirement.

Individuals or families of low or moderate income must occupy that percentage of completed units in such project applicable to the project under paragraph (b)(1) of this section continuously during the qualified project period. For this purpose, a unit occupied by an individual or family who at the commencement of the occupancy is of low or moderate income is treated as occupied by such an individual or family during their tenancy in such unit, even though they subsequently cease to be of low or moderate income. Moreover, such unit is treated as occupied by an individual or family of low or moderate income until reoccupied, other than for a temporary period, at which time the character of the unit shall be redetermined. In no event shall such temporary period exceed 31 days.

(i) In general.

Unless corrected within a reasonable period, noncompliance with the requirements of this paragraph (b) shall cause the project to be treated as other than a project described in section 103(b)(4)(A) and this paragraph (b) as of the date of issue. After an issue to provide such project ceases to qualify, subsequent conformity with the requirements will not alter the taxable status of such issue.

(ii) Correction of noncompliance.

If the issuer corrects any noncompliance arising from events occurring after the issuance of the obligation within a reasonable period, such noncompliance (e.g., an unauthorized sublease) shall not cause the project to be a project not described in this paragraph (b). A reasonable period is at least 60 days after such error is first discovered or would have been discovered by the exercise of reasonable diligence.

(iii) Involuntary loss.

(i) For obligations issued after April 24, 1979, and prior to September 4, 1982, a period of 20 years commencing on the later of the date that the project becomes available for occupancy or the date of issue of the obligations. The requirement of paragraph (b)(5)(ii) of this section shall be deemed met if the owner of the project contracts with a Federal or state agency to maintain at least 20 percent (or 15 percent in the case of targeted areas) of the units for low or moderate income individuals or families (as defined in paragraph (b)(8)(v) of this section) for 20 years in consideration for rent subsidies for such individuals or families for such period.

(ii) For obligations issued after September 3, 1982, a period beginning on the later of the first day on which at least 10 percent of the units in the project are first occupied or the date of issue of an obligation described in section 103 (b)(4)(A) and this paragraph and ending on the later of the date--

(i) Unit.

The term "unit" means any accommodation containing separate and complete facilities for living, sleeping, eating, cooking, and sanitation. Such accommodations may be served by centrally located equipment, such as air conditioning or heating. Thus, for example, an apartment containing a living area, a sleeping area, bathing and sanitation facilities, and cooking facilities equipped with a cooking range, refrigerator, and sink, all of which are separate and distinct from other apartments, would constitute a unit.

(ii) In registered form.

The term "in registered form" has the same meaning as in section 6049. With respect to obligations issued after December 31, 1982, such term shall have the same meaning as prescribed in section 103(j) (including the regulations thereunder).

(iii) Targeted area project.

The term "targeted area project" means a project located in a qualified census tract (as defined in section 6a.103A-2(b)(4)) or an area of chronic economic distress (as defined in section 6a.103A-2(b)(5)).

(iv) Building or structure.

The term "building or structure" generally means a discrete edifice or other man-made construction consisting of an independent foundation, outer walls, and roof. A single unit which is not an entire building but is merely a part of a building is not a building or structure within the meaning of this section. As such, while single townhouses are not buildings if their foundation, outer walls, and roof are not independent, detached houses and row houses are buildings.

(v) Low or moderate income.

Individuals and families of low or moderate income shall be determined in a manner consistent with determinations of lower income families under section 8 of the United States Housing Act of 1937, as amended, except that the percentage of median gross income which qualifies as low or moderate income shall be 80 percent. Therefore, occupants of a unit are considered individuals or families of low or moderate income only if their adjusted income (computed in the manner prescribed with section 1.167(k)-3(b)(3)) does not exceed 80 percent of the median gross income for the area. Notwithstanding the foregoing, the occupants of a unit shall not be considered to be of low or moderate income if all the occupants are students (as defined in section 151(e)(4)), no one of whom is entitled to file a joint return under section 6013. The method of determining low or moderate income in effect on the date of issue will be determinative for such issue, even if such method is subsequently changed. In the event programs under section 8(f) of the Housing Act of 1937, as amended, are terminated prior to the date of issue, the applicable method shall be that in effect immediately prior to the date of such termination.

Example 1. In August 1982, City X issues $10 million of registered bonds with a term of 20 years to be used to finance the construction of an apartment building to be available to members of the general public. X loans the proceeds of the bonds to Corporation M, the tax owner of the project. The loan is secured by a promissory note from M and a mortgage on the project. The mortgage requires annual payments sufficient to amortize the principal and interest on the bonds. Corporation M maintains 20 percent of the units in the project for low or moderate income individuals and meets all of the requirements of this section until 2002, at which time M converts the project to offices. The bonds are industrial development bonds, but because the proceeds are used for construction of residential rental property, which is an exempt facility under section 103(b) (4)(A) and paragraph (b) of this section, section 103(b)(1) does not apply.

Example 2. The facts are the same as in example (1), except that the building is constructed adjacent to a factory, and the factory employees are to be given preference in selecting tenants. The bonds are industrial development bonds and the facility is not an exempt facility under section 103(b)(4)(A) and paragraph (b) of this section because it is not a facility constructed for use by the general public.

Example 3. The facts are the same as in example (1), except that the proceeds of the obligation are provided to N, a cooperative housing corporation, to finance the construction of a cooperative housing project. N sells stock in such cooperative to shareholders, some of whom occupy the units in the cooperative and some of whom rent the units to other persons. Such project is not a residential rental project within the meaning of section 103(b)(A) and section 1.103-8(b) because less than all of the units in the building are used for rental. Further, the bonds are mortgage subsidy bonds under section 103A because more than a significant portion of the proceeds are used to provide financing for residences, some of which are owner-occupied and some of which are used in the trade or business of rental.

Example 4. On February 1, 1984, County Z issues registered obligations with a term of 3 years and loans the proceeds to Corporation V to construct a garden apartment project for tenants who are 65 years or older. The mortgage on the project secures the loan. At the end of 3 years, V obtains permanent financing for the project from a commercial lender. The project is not a targeted area project. V has not contracted with any Federal or state agency to provide rental assistance under section 8 of the United States Housing Act of 1937. As a condition for providing financing for construction, Z requires that the deed to the project contain a covenant that requires the project be used for elderly tenants and restricts occupancy of 20 percent of the units in the project to individuals or families of low or moderate income. Further, the deed provides that "Such covenant shall run with and bind the land, from the date that ten percent of the units in the project are first occupied until ten years after the date that at least half the units are first occupied. The right to enforce these restrictions is vested in County Z." In 1990, however, less than 20 percent of the units are occupied by families or individuals of low or moderate incomes, and three months after learning of this condition County Z had not commenced enforcement of the covenant. Although on the date of issue the proceeds of the obligation were used to provide a residential rental project, the obligation will not be treated as providing a residential rental project within the meaning of section 103 (b)(4)(A) as of February 1, 1984, because the project did not meet the requirements of this paragraph for at least 10 years after at least 50 percent of the units are first occupied.

Example 5. On January 15, 1983, State X issues registered obligations with a term of 15 years, the proceeds of which are loaned to Corporation P to construct an apartment building. The project will be a "targeted area project", within the meaning of section 1.103-8(b)(8)(iii). Corporation P intends to rent all the units to individuals for their residences, maintaining 15 percent of the units in the project for individuals having low or moderate incomes, for 15 years. In 1988, however, Corporation P converts 80 percent of the units to condominiums. Corporation P repays the loan to State X which, in turn, redeems the obligations. The obligations are not used to provide a residential rental project within the meaning of section 103(b)(4)(A), and all the interest paid or to be paid on such obligations will be includable in gross income.

Example 6. On January 15, 1984, State Z issues registered obligations with a term of 15 years the proceeds of which will be used to acquire and renovate a residential apartment building. Z sells the project to Corporation U and receives a 30-year mortgage. On June 1, 1985, the first occupants of the project commence their tenancies. At least 50 percent of the units in the project are occupied on July 1, 1985. On January 15, 1988, Z issues 35-year refunding bonds the proceeds of which are used to retire the obligations issued in 1984. The prior issue will be discharged by March 15, 1988. In order to meet the requirement of section 1.103-8(b)(5)(ii), at least 20 percent of such units must be occupied by individuals of low or moderate income until January 1, 2005.

Example 7. The facts are the same as in example (6) except that in 1987, the apartment building is substantially destroyed by fire. The building was insured at its fair market value. U does not intend to reconstruct the building but uses a portion of the insurance proceeds to repay the unpaid balance of the mortgage. Z uses this amount to redeem the outstanding bonds at the first available call date. Since the project was substantially destroyed by fire and the outstanding bonds are retired at the first available call date, the requirements of section 103(b)(4)(A) and this paragraph (b) are satisfied with respect to the obligations.

Example 8. The facts are the same as in example (6) except that in 1987 U defaults on the mortgage, and Z obtains title to the project without instituting foreclosure proceedings. Z sells the project to S and uses the proceeds to retire the outstanding bonds. Since S did not obtain the project with obligations described in section 103(b)(4), S is not required to meet the requirements of section 103(b)(4)(A) and this paragraph. Further, the 1984 obligations are obligations described in section 103(b)(4)(A).

Example 9. In September 1983, State W issues $10 million of registered bonds with a term of 3 years, the proceeds of which are to be loaned to Corporation V to finance the construction of an apartment building in a rural community. At the end of 3 years, V obtains permanent financing from Federal Agency T. Agency T will not allow the deed to contain any restrictive covenant relating to the use of the project. Under Federal law, however, T requires that V maintain all of the units in the project for rental to low-income farmworkers for the term of the mortgage, which is 20 years. Further, the mortgage between T and V provides that if T determines that low-income housing is no longer required in the community in which the project is constructed then the repayment of the mortgage may be accelerated. T determines as of the date of issue that low-income housing will be needed in the community for at least 20 years. In 1987, the project fails to meet the requirements of section 1.103-8(b)(5)(ii), relating to occupancy by individuals or families of low or moderate income. Further, T does not require V to correct the failure. Based on the foregoing, the bonds issued by W will be treated as described in section 103(b)(4)(A).

Example 10. The facts are the same as in example (9) except that in 1987, the Federal law is amended to provide that Agency T may not enforce its low-income occupancy requirement. The result is the same.

Example 11. The facts are the same as in example (9) except that in 1987 Agency T determines that due to a change in circumstances in the community in which the project is located low-income rental housing is no longer required. As such, T requires V to repay the mortgage. Since the obligations have been repaid, W has no legal right to enforce the requirements of paragraph (b) with respect to the project. Subsequent nonconformity of the project with the requirements of section 1.103-8(b) under these circumstances will not cause the obligations issued by W to be industrial development bonds within the meaning of section 103(b)(1).

(i) General rules.

Section 103(b)(1) shall not apply to obligations issued before April 25, 1979, which are part of an issue substantially all of the proceeds of which are to be used to provide residential real property for family units. In order to qualify under this paragraph (b) as an exempt facility, the facility must satisfy the public use requirement of paragraph (a)(2) of this section by being available for use by members of the general public.

(ii) Family units defined.

For purposes of this paragraph (b) the term "family unit" means a building or any portion thereof which contains complete living facilities which are to be used on other than a transient basis by one or more persons, and facilities functionally related and subordinate thereto. Thus, an apartment which is to be used on other than a transient basis as a residence by a single person or by a family and which contains complete facilities for living, sleeping, eating, cooking, and sanitation, constitutes a family unit. Such a unit may be served by centrally located machinery and equipment as in a typical apartment building. To qualify as a family unit, the living facilities must be a separate, self-contained building or constitute one unit in a building substantially all of which consists of similar units, together with functionally related and subordinate facilities and areas. Hotels, motels, dormitories, fraternity and sorority houses, rooming houses, hospitals, sanitariums, rest homes, and trailer parks and courts for use on a transient basis do not constitute residential real property for family units.

(iii) Functionally related and subordinate facilities.

Under paragraph (a)(3) of this section, facilities which are functionally related and subordinate to residential real property actually used for family units include, for example, facilities for use by the occupants such as a swimming pool, a parking area, and recreational facilities.

(i) For purposes of section 103(b) (4)(B) and this paragraph, the term "sports facilities" includes both outdoor and indoor facilities. The facility may be designed either as a spectator or as a participation facility. For example, the term includes both indoor and outdoor stadiums for baseball, football, ice hockey, or other sports events, as well as facilities for the participation of the general public in sports activities, such as golf courses, ski slopes, swimming pools, tennis courts, and gymnasiums. The term does not include, however, facilities such as a golf course, swimming pool, or tennis court, which are constructed for use by members of a private club or as integral or subordinate parts of a hotel or motel, or the use of which will be restricted to a special class or group or to guests of a particular hotel or motel, since they are not facilities for the use of the general public as required by paragraph (a)(2) of this section.

(ii) Under paragraph (a)(3) of this section, facilities which are functionally related and subordinate to a sports facility, such as a parking lot, clubhouse, ski slope warming house, bath house, or ski tow, are considered to be part of a sports facility. A ski lodge which consists primarily of overnight accommodations is not functionally related and subordinate to a sports facility.

(i) With respect to bonds sold at or before 5:00 p.m. EST on December 29, 1978, an airport includes service accommodations for the public such as terminals, retail stores in such terminals, runways, hangars, loading facilities, repair shops, parking areas, and facilities which, under paragraph (a)(3) of this section, are functionally related and subordinate to the airport, such as facilities for the preparation of in-flight meals, restaurants, and accommodations for temporary or overnight use by passengers, and other facilities functionally related to the needs or convenience of passengers, shipping companies, and airlines. The term "airport" does not include a landing strip which, by reason of a formal or informal agreement, or by reason of geographic location, will not be available for general public use.

(ii) With respect to bonds sold after 5:00 p.m. EST on December 29, 1978--

(iii) A dock or wharf includes property which, under paragraph (a)(3) of this section, is functionally related and subordinate to a dock or wharf such as the structure alongside which a vessel docks, the equipment needed to receive and to discharge cargo and passengers from the vessel, such as cranes and conveyors, related storage, handling, office, and passenger areas, and similar facilities.

(iv) A mass commuting facility includes real property together with improvements and personal property used therein, such as machinery, equipment, and furniture, serving the general public commuting on a day-to-day basis by bus, subway, rail, ferry, or other conveyance which moves over prescribed routes. Such property also includes terminals and facilities which, under paragraph (a)(3) of this section, are functionally related and subordinate to the mass commuting facility, such as parking garages, car barns, and repair shops. Use of mass commuting facilities by noncommuters in common with commuters is immaterial. Thus, a terminal leased to a common carrier bus line which serves both commuters and long distance travelers would qualify as an exempt facility.

Example 1. B Airport Authority, a political subdivision of State A, owns and operates B Airport. B Airport Authority adds several runways. In view of the expanded area impaired by significant levels of airport noise, the Authority proposes to issue bonds the proceeds of which are to be used to acquire a hospital located adjacent to the airport. The noise level on the acquired property is 40 NEF. By reference to a noise exposure map setting forth noncompatible land uses and by reference to guidelines published by the Federal Aviation Administration, it is established that continued use of the land for a hospital is not compatible with the noise level. Prior to issuing the bonds, B contracts to lease the property to Corporation C to be used for warehouse space. Within 18 months of the bonds' issuance C will remodel the hospital (previously owned by D, who is unrelated to C) with its own funds and rent the facility as a warehouse. Use as a warehouse is determined to be compatible with the level of airport noise impairing the land. The improved land and prospective revenues from the facility's rental are security for the proposed issuance. Based on the foregoing, the acquired land satisfies the public use test. Furthermore, it is functionally related and subordinate to the airport because the improvements are to be used in an essentially different manner than prior to the land's acquisition. The bonds are industrial development bonds. However, section 103(b)(1) does not apply unless the provisions of section 103(b)(13) and section 1.103-11 apply.

Example 2. The facts are the same as in Example (1) except that a substantial portion of the proceeds of the bond issue is allocated to the acquisition of a limited interest in an additional tract of land (also impaired by airport noise measured at 40 NEF) on which an office building stands. The limited interest holds B harmless for damages caused by airport noise and restricts uses of the tract after the building is retired to those compatible with noise levels caused by the airport. Based on the foregoing, such interest satisfies the public use test. Furthermore, the interest is functionally related and subordinate to the airport because it is solely to mitigate damage attributable to airport noise, in part by restricting future land uses. The bonds are industrial development bonds. However, section 103(b)(1) does not apply unless the provisions of section 103(b)(13) or section 1.103-11 apply.

Example 3. On June 1, 1982, M Airport Authority, a political subdivision of State O, issues obligations, the proceeds of which are loaned to X Corporation, a nonexempt person. X uses the proceeds to construct a hotel adjacent to the main terminal building at M Airport. X will be unconditionally liable for repayment of the proposed obligations. The hotel will be used to provide temporary and overnight accommodations for airline passengers using M Airport. The number of rooms in the hotel is reasonable for an airport of M's size, taking into account the current and projected passenger usage of the terminal facility. In addition to guest rooms, the hotel will contain a restaurant, small retail stores (such as a gift shop and newsstand), and limited recreation facilities (such as a swimming pool). The hotel will also contain several multipurpose rooms suitable for use as meeting rooms. The number and size of these rooms will be in reasonable proportion to the number and size of the guest rooms in the hotel. Use of the guest rooms, restaurant and stores, recreational facilities, and meeting rooms by air passengers arriving at or departing from M Airport will be incidental to the use of the hotel by air passengers for temporary and overnight accommodations. The hotel is of a character and size commensurate with the character and size of M Airport. Consequently, applying the provisions of section 1.103-8(e)(2), the hotel is functionally related and subordinate to M Airport. The obligations are industrial development bonds. Section 103(b)(1) does not apply to the obligations, however, unless the provisions of section 103(b)(10) and section 1.103-11 apply.

Example 4. On June 1, 1982, N Airport Authority, a political subdivision of State P, issues obligations the proceeds of which are loaned to Y Corporation, a nonexempt person. Y uses the proceeds to construct a hotel adjacent to the main terminal building at N Airport. Y Corporation will be unconditionally liable for repayment of the proposed obligations. The hotel will contain extensive recreational facilities, including a large roof-top swimming pool, tennis courts, and a health club. In addition, facilities for conferences consisting of a ballroom-sized meeting room capable of being partitioned by movable panels and several smaller meeting rooms will be constructed. The number of rooms in the hotel will substantially exceed the number which is reasonable based on the current and projected passenger usage of the terminal facility. Because of the presence of extensive recreational and conference facilities, as well as the presence of on excessive number of rooms at the hotel, the hotel fails to be of a character and size commensurate with the character and size of N Airport. The result would be the same if the hotel did not have extensive recreational facilities. Consequently, the hotel is not functionally related and subordinate to N Airport under section 1.103-8(e)(2). The obligations are industrial development bonds and interest thereon is not excluded from gross income by reason of subsection (a)(1) or (b)(4) of section 103.

(i) Section 103(b) (4)(E) provides that section 103(b)(1) shall not apply to obligations issued by a State or local governmental unit which are part of an issue substantially all of the proceeds of which are to be used to provide sewage disposal facilities, solid waste disposal facilities, or facilities for the local furnishing of electric energy or gas. In order to qualify under section 103(b) (4)(E) as an exempt facility, the facility must satisfy the public use requirement of paragraph (a)(2) of this section. A public utility facility described in this subparagraph (with the exception of sewage and solid waste disposal facilities which will be treated in all events as serving the general public) will satisfy the public use requirement only if such facility, or the output thereof, is available for use by members of the general public.

(ii) A facility for the local furnishing of electric energy or gas is, for purposes of applying the public use test in paragraph (a)(2) of this section, available for use by members of the general public if (a) the owner or operator of the facility is obligated, by a legislative enactment, local ordinance, regulation, or the equivalent thereof, to furnish electric energy or gas to all persons who desire such services and who are within the service area of the owner or operator of such facility, and (b) it is reasonably expected that such facility will serve or be available to a large segment of the general public in such service area. For rules with respect to facilities for the furnishing of water, see paragraph (h) of this section.

(i) The term "sewage disposal facilities" means any property used for the collection, storage, treatment, utilization, processing, or final disposal of sewage.

(ii) The term "facilities for the local furnishing of electric energy or gas" means property which--

For purposes of this subdivision, a city which is not within, or does not consist of, one or more counties (or a political equivalent) shall be treated as a county (or a political equivalent). A facility for the generation of electric energy otherwise qualifying under this subdivision will not be disqualified because it is connected to a system for interconnection with other public utility systems for the emergency transfer of electric energy. The facilities need not be located in the area served by them. Also, the term "facilities for the local furnishing of electric energy or gas" does not include coal, oil, gas, nuclear cores, or other materials performing a similar function.

(i) For purposes of section 103(b) (4)(F) and this paragraph, property is a pollution control facility to the extent that the test of either subdivision (iii) or (iv) of this subparagraph is satisfied, but only if--

(ii) Property is described in this subdivision if it is property to be used, in whole or in part, to abate or control water or atmospheric pollution or contamination by removing, altering, disposing, or storing pollutants, contaminants, wastes, or heat. In the case of property to be used to control water pollution, such property includes the necessary intercepting sewers, pumping, power, and other equipment, and their appurtenances. For rules relating to facilities which remove pollutants from fuel or certain other items, see subdivision (vi) of this subparagraph.

(iii) In the case of an expenditure for property which is designed for no significant purpose other than the control of pollution, the total expenditure for such property satisfies the test of this subdivision. Thus, where property which is to serve no function other than the control of pollution is to be added to an existing manufacturing or production facility, the total expenditure for such property satisfies the test of this subdivision. Also, if an expenditure for property would not be made but for the purpose of controlling pollution, and if the expenditure has no significant purpose other than the purpose of pollution control, the total expenditure for such property satisfies the test of this subdivision even though such property serves one or more functions in addition to its function as a pollution control facility.

(iv) In the case of property to be placed in service for the purpose of controlling pollution and for a significant purpose other than controlling pollution, only the incremental cost of such facility satisfies the test of this subdivision. The "incremental cost" of property is the excess of its total cost over that portion of its cost expended for a purpose other than the control of pollution.

(v) An expenditure has a significant purpose other than the control of pollution if it results in an increase in production or capacity, or in a material extension of the useful life of a manufacturing or production facility or a part thereof.
