1.148-5A—Yield and valuation of investments.
(b)
(2)
For all purposes of section 148, an issuer may treat all of the yield restricted nonpurpose investments in a refunding escrow and a sinking fund that is reasonably expected as of the issue date to be maintained to reduce the yield on the investments in the refunding escrow as a single investment having a single yield, determined under § 1.148(b)(2).
(c)
(2) Manner of payment—
Except as otherwise provided in § 1.148-5(c)(2)(ii), an amount is paid under § 1.148-5(c) if it is paid to the United States at the same time and in the same manner as rebate amounts are required to be paid or at such other time or in such manner as the Commissioner may prescribe. For example, yield reduction payments must be made on or before the date of required rebate installment payments as described in § 1.148-3(f). The date a payment is required to be paid is determined without regard to § 1.148-3(h). An amount that is paid untimely is not taken into account under this paragraph (c) unless the Commissioner determines that the failure to pay timely is not due to willful neglect. The provisions of § 1.148-3(i) apply to payments made under § 1.148-5(c).
(c)
(3)
Section 1.148-5(c)(1) does not apply to investments allocable to gross proceeds of an advance refunding issue, other than—
(C)
Transferred proceeds to which § 1.148-5(c)(3)(i)(E) applies, but only to the extent necessary to satisfy yield restriction under section 148(a) on those proceeds treating all investments allocable to those proceeds as a separate class.
(d)
(3)
Section 1.148-5(d)(3)(i) does not apply if the investment is allocated from one issue to another issue as a result of the transferred proceeds allocation rule under § 1.148-9(b) or the universal cap rule under § 1.148-6(b)(2), provided that both issues consist exclusively of tax-exempt bonds. In addition, § 1.148-5(d)(3)(i) does not apply to investments in a commingled fund (other than a bona fide debt service fund) unless it is an investment being initially deposited in or withdrawn from a commingled fund described in § 1.148-6(e)(5)(iii).
(e)
(2)
(B) External commingled funds. For any semiannual period, a commingled fund satisfies the 10 percent requirement of § 1.148-5(e)(2)(ii)(B) if—
(1) Based on average amounts on deposit, this requirement was satisfied for the prior semiannual period; and
(2) The fund does not accept deposits that would cause it to fail to meet this requirement.
(iii) Special rule for guaranteed investment contracts.
For a guaranteed investment contract, a broker's commission or similar fee paid on behalf of either an issuer or the provider is treated as an administrative cost and, except in the case of an issue that satisfies section 148(f)(4)(D)(i), is not a qualified administrative cost to the extent that the present value of the commission, as of the date the contract is allocated to the issue, exceeds the present value of annual payments equal to .05 percent of the weighted average amount reasonably expected to be invested each year of the term of the contract. For this purpose, present value is computed using the taxable discount rate used by the parties to compute the commission or, if not readily ascertainable, a reasonable taxable discount rate.
