The managers of Virginia’s pension fund got bonuses in 2010 and 2011 even though they failed to meet the benchmarks that would justify such payouts, a new report shows.

Investors for the Virginia Retirement System used to get bonuses based on the pension fund’s performance. No one received a bonus in fiscal year 2009, and afterward the fund’s trustees changed the system so that they — and not a performance benchmark — would decide who got a bonus.
