46 C.F.R. § 391.3
(2) Net proceeds from agreement vessels and fund earnings.
(i) (a) Section 607(d)(1)(B) provides that gain from a transaction referred to in section 607(b)(1)(C) of the Act and § 391.2(a)(1)(iii) (relating to ceilings on deposits of net proceeds from the sale or other disposition of agreement vessels) is not to be taken into account for purposes of the Code if an amount equal to the net proceeds from transactions referred to in such sections is deposited in the fund. Such gain is to be excluded from gross income of the party for the taxable year to which such deposit relates. Thus, the gain will not be taken into account in applying section 1231 of the Code for the year to which the deposit relates.
(b) [Reserved]
(ii) (a) Section 607(d)(1)(C) of the Act provides that the earnings (including gains and losses) from the investment and reinvestment of amounts held in the fund and referred to in section 607(b)(1)(D) of the Act and § 391.2(a)(1)(iv) shall not be taken into account for purposes of the Code if an amount equal to such earnings is deposited into the fund. Such earnings are to be excluded from the gross income of the party for the taxable year to which such deposit relates.
(b) However, for purposes of the basis adjustment under section 1232(a)(3)(E) of the Code, the ratable monthly portion of original issue discount included in gross income shall be determined without regard to section 607(d)(1)(C) of the Act.
(3) Time for making deposits.
(4) Date of deposits.
(ii) (a) For taxable years beginning after December 31, 1969, and prior to January 1, 1971, where an application for a fund is filed by a taxpayer prior to January 1, 1972, and an agreement is executed and entered into by the taxpayer prior to March 1, 1972,
(b) For taxable years beginning after December 31, 1970, and prior to January 1, 1972, where an application for a fund is filed by a taxpayer prior to January 1, 1973, and an agreement is executed and entered into by the taxpayer prior to March 1, 1973, and
(c) For taxable years beginning after December 31, 1971, and prior to January 1, 1975, where an agreement is executed and entered into by the taxpayer on or prior to the due date, with extensions, for the filing of his Federal income tax return for such taxable year, deposits in a fund which are made within 60 days after the date of execution of the agreement, or on or before the due date, with extensions thereof, for the filing of his Federal income tax return for such taxable year or years, whichever date shall be later, shall be deemed to have been made on the date of the actual deposit or as of the close of business of the last regular business day of each such taxable year or years to which such deposits relate, whichever day is earlier.
