Earnings per share of QTS Realty Trust, Inc.

Basic income per share is calculated by dividing the net income (loss) attributable to common shares by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share adjusts basic income per share for the effects of potentially dilutive common shares. Unvested restricted stock awards and our forward sale contracts described in Note 9 contain non-forfeitable rights to dividends and thus are participating securities and are included in the computation of basic earnings per share pursuant to the two-class method for all periods presented. The two-class method is an earnings allocation formula that treats a participating security as having rights to undistributed earnings that would otherwise have been available to common stockholders. Accordingly, service-based restricted stock awards and the forward sale contracts were included in the calculation of basic earnings per share using the two-class method for all periods presented to the extent outstanding during the period.

The computation of basic and diluted net income per share is as follows (in thousands, except per share data, and unaudited):
