Inc. for $8.0 million in cash. We intend to hold these patents as part of our strategy to protect and defend Pandora from patent-related litigation. These patents are being amortized over the estimated useful life of the patents of eleven years. As of December 31, 2013 and 2014, the net carrying amount of these patents was $7.6 million and $6.9 million, including accumulated amortization of $0.4 million and $1.1 million. Amortization expense for the eleven months ended December 31, 2013 and the twelve months ended December 31, 2014 was $0.4 million and $0.7 million. The following is a schedule of future amortization expense related to patents as of December 31, 2014:   As of   December 31,   2014   (in thousands) 2015 $ 733 2016 733 2017 733 2018 733 2019 733 Thereafter 3,275 Total future amortization expense $ 6,940 Restricted Cash As part of our original May 2011 credit facility, we had entered into a cash collateral agreement in connection with the issuance of letters of credit that were used to satisfy deposit requirements under facility leases, refer to Note 8 “Debt Instruments” for more information. In September 2013, we amended the credit facility and terminated the cash collateral agreement. As a result, our outstanding letters of credit no longer required cash collateral and all cash collateral that was considered restricted cash was returned to us in September 2013. Pending Acquisition   In June 2013, we entered into a local marketing agreement to program KXMZ-FM, a Rapid City, South Dakota-area terrestrial radio station. In addition, we entered into an agreement to purchase the assets of KXMZ-FM for a total purchase price of approximately $0.6 million in cash, subject to certain closing conditions. As of December 31, 2014, we have paid $0.4 million of the purchase price, which is included in the other long-term assets line item of our balance sheets.   The completion of the KXMZ-FM acquisition is subject to various closing conditions, which include, but are not limited to, regulatory approval by the Federal Communications Commission. Upon completion of these conditions, we expect to account for this acquisition as a business combination.
