C.R.S. § 8-73-110

(A) The individual’s separation from the employer awarding the payment is not due to a retirement pursuant to section 8-73-108 (4)(m) or (5)(e)(XXIII);

(B) The individual presents proof to the division within fourteen calendar days from date of claim or sixty calendar days of receipt of such lump-sum payment, whichever is later, that this total payment has been reinvested into an individual retirement account or KEOGH plan, as defined in 26 U.S.C. 408 or 26 U.S.C. 401, and such proof establishes that the investment is for a duration of at least one year; except that such lump-sum retirement payment shall not be considered to be received by the individual until the entire balance has been so received. Should a portion of the payment be ineligible for reinvestment and the claimant presents proof that the total eligible portion has been reinvested, only the remaining uninvested portion will be prorated in accordance with subparagraph (III) of this paragraph (a).

(III) When an individual receives a lump-sum retirement payment from a plan, fund, or trust that has been contributed to by a base period employer and the payment does not meet all of the criteria established in subparagraph (II) of this paragraph (a), then the division shall postpone the individual’s benefits for a number of calendar weeks equal to the gross amount of the lump-sum payment divided by the individual’s full-time weekly wage. However, when an individual receives a lump-sum retirement payment from a plan, fund, or trust as described in this subparagraph (III), but only reinvests a portion of that payment as required in subparagraph (II) of this paragraph (a), or when an individual otherwise withdraws an amount from a plan, fund, or trust that is less than the total lump sum of the account, then the division shall consider only the portion that is received but not reinvested pursuant to subparagraph (II) of this paragraph (a) in determining the number of calendar weeks that the individual’s benefits are postponed.

(IV) An individual’s weekly benefit amount shall not be reduced by any amount of a primary insurance benefit under Title II of the federal “Social Security Act” that has been contributed to by a base period employer if the employee has made contributions to federal social security.
