1.contraction risk occurs as mortgage rates fall, prepayment rates increase, and the average life of the pass-through security decreases 其中prepayment rates,指mortgage loan的提前偿还的速度,对不? 2.CPR is annual rate, at which a mortgage pool balance is assumed to be prepaid during the life of the pool 这句话,如何理解?

同学你好,
1.对的,prepayment rates就是提前还款率的意思
2.这句话的意思是说:CPR是一个年化利率,它就是表示年初贷款池余额预计在年底预付的百分比
例如CPR=4%就是年提前还款率等于4%,也就是每年偿还4%的贷款池余额。
