Significant changes to that facility include the extension of the maturity to April 30, 2017 and an increase of the available commitments from $1.5 billion to $2.0 billion.

If Available Cash (as defined in the facility) plus the availability under the facility is greater than $1.0 billion, amounts drawn under the facility will bear interest either (i) at a rate of 150 basis points over LIBOR or (ii) 50 basis points over an alternative base rate (the higher of the prime rate, the federal funds rate plus 50 basis points or LIBOR plus 100 basis points), and undrawn amounts under the facility will be subject to an annual commitment fee of 37.5 basis points. If Available Cash plus the availability under the facility is equal to or less than $1.0 billion, then amounts drawn under the facility will bear interest either (i) at a rate of 175 basis points over LIBOR or (ii) 75 basis points over an alternative base rate, and undrawn amounts under the facility will be subject to an annual commitment fee of 25 basis points.

Loans under this facility bear interest, at our option, at (i) 375 basis points over LIBOR (subject to a minimum LIBOR rate of 100 basis points) or (ii) 275 basis points over an alternative base rate (the higher of the prime rate, the federal funds rate plus 50 basis points or LIBOR plus 100 basis points).
