Pensions are never going to be "paid out" because they are a continuing liability and based upon whether the reserves in hand plus the anticipated future revenues cover the pension obligations; that's the whole foundation of pensions (I used to be a building trades pension fund attorney).
The question is whether the actuaries have made a "conservative" model or "aggressive" model in what future revenues are needed. "Fully funded", which is the key issue, means whether the fund can pay out all current and future liabilities or not, based on the future revenues (new payments and returns on investments).
A surplus is a big thing here in the Golden State, it just shows that if you are willing to pay for things (taxes), you do not have to deficit spend. As a taxpayer, I'm proud that we have taken steps to get our house in order. In our local schools, the monies are having an impact.
