[1] The Level 3 fair value measurement also assumes that issuers of asset size $15 billion and above will generally prepay during 2013, unless issued at a variable rate with a spread of less than 150 bps over LIBOR; other issuers are expected to prepay at a rate of 1% annually, unless issued at a fixed rate of 8% or more by a bank reasonably expected to be able to prepay.
