American Home Mortgage Servicing, one of the largest subprime mortgage servicers, is urging the U.S. Treasury to organize a plan to boost principal reductions for up to 1 million homeowners by unlocking loans from securities.

The servicer is asking for amendments to contracts that govern treatment of delinquent loans in mortgage securities. Currently, most contracts don’t allow sales of loans prior to foreclosure, and in many cases don’t permit a servicer to lower principal when a loan is modified.
