In connection with this transaction, we retired $42.5 million of principal amount of our convertible subordinated notes in exchange for the same principal amount of senior secured notes. As a result of these transactions, we received cash of $82.5 million, less approximately $4.3 million in transaction costs, of which $25.0 million is required to be maintained in a reserve account until July 1, 2015. The senior secured notes bear interest at 12.0% per annum payable in cash semi-annually in arrears on January 15 and July 15 of each year.
