A state with very volatile revenues, Wyoming has had a bit of a see-saw effect in its pension funding. The state paid only 75% of its annual required contribution in 2004 and 69% the year before, but in other years, including 2005 and 2006, it has contributed substantially more than its actuaries deemed necessary. (Information about the state's funding levels prior to 2000 is not available.) As a whole, the pension system is in fine shape. Wyoming's non-pension benefits are very modest. The state does not provide cash support for retiree health premiums, but only an “implicit subsidy” that comes from including retired and current employees in the same health plan.
