The total entails mostly funds appropriated by the General Assembly and 0.58 percent of member salary contributed by school districts according to state law. The vast majority of the total employer contribution is state funds.
1990 $ 617,000,000 $ 282,969,000 $ 269,000,000
2000 $1,003,612,000 $ 686,384,000 $ 688,586,000
2011 $2,743,221,000 $2,293,321,000 $2,323,668,000
Between 1970 and 2013, because it has not fully funded TRS, the state has redirected [or STOLEN approximately $15 billion] from the System for other budget priorities... We can only estimate roughly what the System's funded status would be if the state had paid TRS everything that the actuaries required since 1970... With investment income added in, it is quite probable that if that $15 billion had been delivered to TRS that the System would right now be fully funded.
TRS currently has an unfunded liability of $53 billion. We only have 42 percent of the money on hand right now to meet accumulated obligations over the next 30 years.
