(a) Except as provided in paragraph (c) of this section, if the annuity of an employee or Member commences after January 3, 1988, and before October 1, 1989, the lump-sum credit payable under § 842.705 is payable to the individual, or his or her survivors, according to the following schedule:

(1) Sixty percent of the lump-sum credit is payable at the time of retirement, and

(2) Forty percent is payable, with interest determined under section 8334(e)(3) of title 5, United States Code, one year after the time of retirement.
