Colo. Rev. Stat. § 8-77-105
The provisions of sections 8-77-101 to 8-77-104, to the extent that they relate to the unemployment trust fund, shall be operative only so long as such unemployment trust fund continues to exist and so long as the secretary of the treasury of the United States of America continues to maintain for this state a separate book account of all funds deposited therein by this state for benefit purposes, together with this state's proportionate share of the earnings of such unemployment trust fund, from which no other state is permitted to make withdrawals. If such unemployment trust fund ceases to exist, or such separate book account is no longer maintained, all moneys, properties, or securities therein belonging to the unemployment compensation fund of this state shall be transferred to the treasurer of the unemployment compensation fund, who shall hold, invest, transfer, sell, deposit, and release such moneys, properties, or securities in a manner approved by the director of the division in accordance with provisions of articles 70 to 82 of this title. Such moneys shall be invested in readily marketable classes of securities as now provided by law with respect to public moneys of the state. Such investment, at all times, shall be so made that all the assets of the fund shall always be readily convertible into cash when needed for the payment of benefits. The treasurer shall dispose of securities or other properties belonging to the unemployment compensation fund only under the direction of the director of the division.
