Programming costs included in the accompanying consolidated statements of operations and comprehensive income (loss) for the years ended December 31, 2013, 2014 and 2015, were $134.0 million, $148.6 million and $176.2 million, respectively.

In the regular course of evaluating the remaining usefulness of its various program rights, the Company may determine that certain rights may be of little future program value. In such instances, the Company shortens the estimated remaining life of the asset to zero, thereby accelerating amortization of the remaining net book value. During the years ended December 31, 2013, 2014 and 2015, such changes in estimates resulted in additional amortization of programming rights of $4.5 million, $7,000 and $15.0 million, respectively. This expense is included as a component of non‑affiliate programming costs in the accompanying consolidated statement of operations and comprehensive income (loss). The Company expects to amortize $4.0 million to $5.0 million of the $25.0 million net book value at December 31, 2015 of owned programming during the year ended December 31, 2016.

At December 31, 2014 and 2015, $39.8 million and $24.0 million, respectively, of programming rights were included in prepaid programming rights in the accompanying consolidated balance sheets. The various license periods associated with such amounts had not commenced as of the respective balance sheet dates.
