The Lenape tribe got a better deal on the sale of Manhattan island than New York City’s pension funds have been getting from Wall Street, according to a new analysis by the city comptroller’s office.

The analysis concluded that, over the past 10 years, the five pension funds have paid more than $2 billion in fees to money managers and have received virtually nothing in return, Comptroller Scott M. Stringer said in an interview on Wednesday.

“We asked a simple question: Are we getting value for the fees we’re paying to Wall Street?” Mr. Stringer said. “The answer, based on this 10-year analysis, is no.”

Until now, Mr. Stringer said, the pension funds have reported the performance of many of their investments before taking the fees paid to money managers into account. After factoring in those fees, his staff found that they had dragged the overall returns $2.5 billion below expectations over the last 10 years.
