We reported a net loss for the years ended December 31, 2010, 2011, 2012, 2013, 2014 and the three months ended March 31, 2015 and would have needed to generate additional income of $17,638,746, $15,304,095, $19,712,980, $66,083,532, $36,140,133 and $10,582,871, respectively, to cover our fixed charges of $261,425, $141,900, $146,520, $298,980, $411,510 and $102,300, respectively.
For purposes of computing the ratio of earnings to fixed charges, earnings consist of net loss plus fixed charges. Fixed charges consist of interest expense and an estimate of the interest within rental expense.
For purposes of computing the ratio of earnings to combined fixed charges and preferred stock dividends, earnings consist of net loss plus fixed charges. Combined fixed charges and preferred stock dividends consist of interest expense, an estimate of interest within rental expense and preferred stock dividends.
