Audit finds overpayments to San Jose retirees  — Some San Jose
retirees may not be getting some extra money they were expecting
because of a miscalculation in pension payments.  City officials
say thousands of retirees were apparently overpaid pension
bonuses for several years.  It's not known yet how much was
overpaid, or whether the nearly 2,900 beneficiaries in the
Federated City Employees' Retirement System will end up owing
money to the city.  The overpayments don't impact retirees'
regular pension payments, but involves the calculation of an
additional benefit referred to as a "13th check."  The
additional check is paid out when earnings on pension fund
investments surpass their growth target.  The overpayments were
discovered during an internal audit.
