Yes, that's what it is. Some plans allow it -- so some may work a LOT of OT in their last year, or cash in all their unused leave toward final year compensation and things like that -- and these count for calculating their pension. In a few extreme cases, pensioners are able to get more from their pension than they ever received in base pay. It's probably no coincidence that some of the most threatened and insolvent plans allow it.
Actually Zip, spiking is more, much more, that just using OT or leave pay to increase the final few years salary. In Illinois, it was fairly common for early out packages to include huge raises for each of the last few years once the employee signed an intent to retire after that period.
So, a School Supt making $300k (yes, they make that much here) might get a raise to $400k his/her final years. Then, the retirement formula would wind up cranking out a pension equal to or greater than the Supt's working salary.
What really hurt about this common practice is the fact that the acturial info used to calculate pension fund requirements DID NOT include the fact that, due to spiking, pensions would be much, much higher than the formulas indicated.
So, two problems here. Politicians underfunding calcuated pension fund requirements and making promises to "make it up next year" plus pension fund requirements being dramatically understated due to spiking. That is, actual pensions being much higher than the formulas would indicate they're going to be.
In hindsight, it should be no surpirse to Illinoisians that the public pension funds are in for huge problems and will require significant tax rate increases to bail out, despite the current reform legislation.
I've mentioned several times that our northern neighbor, Wisconsin, has a viable system. It's 100% funded and pensions vary with market performance but never dip below the original amount. Changes in payout are buffered/smoothed by a five year averaging algorithm. It's pretty clever.
An interesting side note is that as the politicians try to wrangle a way out of this, they find themselves between a rock and a hard place. If they move funds away from social programs toward pension funding, lower income constituents and their advocates scream bloody murder. If the move money away from pension funding toward social programs, unionized public employees stop supporting them and launch publicity campaigns against the politicians. So there is a back and forth "spread the pain" component hindering objective solutions based on sound financial and management theory.
If it wasn't so sad and scary, it'd be funny.......
