The current purchase limit under the Securitization Facility is $500 million. The Securitization Facility was amended for the seventh time on February 6, 2012 to add a new purchaser and extend the facility termination date to February 4, 2013. There is a program fee equal to the Commercial Paper Rate of 0.26%, plus 0.75% as of March 31, 2012. The unused facility fee is payable at a rate of 0.35% per annum as of March 31, 2012.
