[1] As discussed below, Liberty acquired its interest in Charter Communications, Inc. during May 2013 for approximately $2.6 billion. Our share of losses related to Charter in 2013 included $51 million of losses due to the amortization of the excess basis of our investment.
[2] On January 18, 2013, as discussed in note 4, Liberty acquired an additional 50 million common shares and acquired a controlling interest in SIRIUS XM and as a result consolidates SIRIUS XM as of such date. SIRIUS XM has an investment in SIRIUS XM Canada that was recorded at fair value in purchase accounting. See discussion below of SIRIUS XM Canada.
[3] SIRIUS XM recognized a $3.0 billion tax benefit during the year ended December 31, 2012. SIRIUS XM recorded the tax benefit as the result of significant positive evidence that a valuation allowance was no longer necessary for its recorded deferred tax assets. The Company recognized its portion of this benefit ($1,229 million) based on our ownership percentage at the time of the recognition of the deferred tax benefit by SIRIUS XM.
[4] During the first quarter of 2013, Liberty acquired an additional 1.7 million shares of Live Nation for approximately $19 million. During the year ended December 31, 2012 the Company acquired approximately 11 million shares of Live Nation for $107 million.
