Revised projections that the University endowment will lose 30 percent of its value by the end of this fiscal year have forced administrators to cut next year’s budget by $88 million, President Tilghman announced in an e-mail to the campus community Monday morning. The value of the endowment is now expected to decline from $16.4 billion on June 30, 2008, to roughly $11.5 billion by June 30, 2009. The decline will force the University to cut 6.8 percent of this year’s $1.3 billion operating budget for the fiscal year beginning July 1.
