Note 3.Earnings per Share

We present basic earnings per share (“EPS”) and diluted EPS for our Class A and Class B common stock. The EchoStar Tracking Stock (see Note 4 for definitions and a further discussion of the preferred tracking stock, the EchoStar Group and the Hughes Retail Group) is a participating security that shares in our consolidated earnings and therefore, effective March 1, 2014, the issuance date of the EchoStar Tracking Stock, we apply the two-class method to calculate EPS. Under the two-class method, we allocate net income or loss attributable to EchoStar between common stock and the EchoStar Tracking Stock considering both dividends declared on each class of stock and the participation rights of each class of stock in undistributed earnings. Based on the 51.89% economic interest in the Hughes Retail Group, represented by the EchoStar Tracking Stock, we allocate undistributed earnings to the EchoStar Tracking Stock based on 51.89% of the attributed net income or loss of the Hughes Retail Group. Moreover, because the reported amount of “Net income attributable to EchoStar” in our consolidated statements of operations and comprehensive income (loss) excludes DISH Network’s 28.11% economic interest (represented by the HSS Tracking Stock) in the net loss of the Hughes Retail Group (reported as a noncontrolling interest), the amount of consolidated net income or loss allocated to holders of Class A and Class B common stock effectively excludes an aggregate 80.0% of the attributed net loss of the Hughes Retail Group.

Basic EPS for our Class A and Class B common stock excludes potential dilution and is computed by dividing “Net income attributable to EchoStar common stock” by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if our common stock awards were exercised. The potential dilution from common stock awards was computed using the treasury stock method based on the average market value of our Class A common stock during the period. The calculation of our diluted weighted-average common shares outstanding excluded options to purchase shares of our Class A common stock, whose effect would be anti-dilutive, of 2.3 million, 2.3 million and 2.7 million shares for the years ended December 31, 2015, 2014 and 2013, respectively. The calculation also excluded 0.7 million shares of our Class A common stock that were issuable pursuant to our performance based stock incentive plans contingent upon meeting a company-specific performance measure by March 31, 2015, that was not achieved and which resulted in the expiration of such awards as of March 31, 2015.
