Despite a forecast earlier this year that City pension funds would break even this year, it now appears that the funds will post large losses for the year. Three quarters of the way through the current fiscal year, city funds have lost almost $5 billion. Taxpayers are the ones who likely be called upon to make the funds whole and meet worker benefit commitments. Of the billions that will have to be repaid, the first installment will be $190 million in 2010.
