(G) A Roth IRA described in Section 408A of the federal Internal Revenue Code.

(4) "Eligible rollover distribution" means any distribution of all or any portion of the balance to the credit of the distributee; provided, however, such term shall not include:

(A) Any distribution that is one of a series of substantially equal periodic payments made not less frequently than annually for the life or life expectancy of the distributee or the joint lives or joint life expectancies of the distributee and the distributee's designated beneficiary or for a specified period of ten years or more;

(C) The portion of any distribution that is not includable in gross income; or

(D) Any other distribution that is reasonably expected to total less than $200.00 during the year.

Such term shall include a distribution to a surviving spouse made on or after January 1, 2002.

(b) Notwithstanding any other provisions of this title to the contrary that would otherwise limit a person's election under this Code section, a member of a retirement or pension system subject to this title may elect, at the time and in the manner prescribed by the board of trustees of such system, to have any portion of an eligible rollover distribution, as such term is defined in Section 402(c) of the federal Internal Revenue Code, paid directly to an eligible retirement plan, as such term is defined in Section 402(c) of the federal Internal Revenue Code, specified by the person in a direct rollover.

(c) A portion of a distribution made on or after January 1, 2002, shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions that are not includable in gross income; provided, however, that such portion may be transferred only to:

(1) An individual retirement account or annuity described in Section 408(a) or (b) of the federal Internal Revenue Code;

(d) Notwithstanding any other provision of this title to the contrary, a nonspouse designated beneficiary may roll over the distribution only to an individual retirement account or individual retirement annuity established for the purpose of receiving the distribution, and the account or annuity shall be treated as an inherited individual retirement account or annuity.
