Because these pension payments are a legal obligation for the state, you assess their risk to be similar to other state debt, and therefore the cost of capital should be similar to Florida’s current borrowing rate. Begin by first searching for the State of Florida’s bond rating. Once you know the rating, go to FMSBonds Inc. (www.fmsbonds.com/market-yields/) to find out what Florida bonds at different maturities with this rating are currently yielding.
