Colorado Revised Statutes Title 31. Government Municipal § 31-30.5-307. State contribution

(b)(I) Each employer having rank escalation and having old hire members shall determine for each such employee the percentage that such employee's years served as of January 1, 1980, bear to the total number of years required for retirement. At retirement, the retirement pension shall be divided into that percentage and the remainder. The portion of the retirement pension equal to that percentage earned as of January 1, 1980, shall be subject to rank escalation as provided under the old hire pension plan, and the remainder of the retirement pension shall be subject to the same adjustment as that determined by the fire and police pension association board of directors pursuant to section 31-31.5-410.

(II) An employer may elect to continue full rank escalation benefits for that portion of the retirement pension subject to the adjustment as provided in subparagraph (I) of this paragraph (b), but no state contribution shall be used to fund such continuation of rank escalation or any unfunded liabilities incurred as a result of such continuation of rank escalation.
