The following tables set forth the computation of basic and diluted earnings (loss) per share of common stock for the years ended December 31, 2013, 2012, and 2011. We computed basic earnings (loss) per share for the years ended December 31, 2013, 2012 and 2011 using the weighted average number of shares outstanding during the periods. Diluted earnings (loss) per share for the years ended December 31, 2013, 2012 and 2011, reflects additional shares of common stock, related to our convertible senior common stock, that would have been outstanding if dilutive potential shares of common stock had been issued, as well as an adjustment to net income available to common stockholders as applicable to common stockholders that would result from their assumed issuance (dollars in thousands, except per share amounts).
