20. LOSS PER SHARE ATTRIBUTABLE TO COMVERSE TECHNOLOGY, INC.'S SHAREHOLDERS

For purposes of computing basic loss per share attributable to Comverse Technology, Inc.'s shareholders, any nonvested shares of restricted stock that have been issued by the Company and which vest solely on the basis of a service condition are excluded from the weighted average number of shares of common stock outstanding because such restricted stock does not allow the holders to receive dividends that participate in undistributed earnings. Incremental potential shares of common stock from stock options, nonvested restricted stock and DSUs are included in the computation of diluted loss per share attributable to Comverse Technology, Inc.'s shareholders except when the effect would be antidilutive. The dilutive impact of subsidiary stock-based awards on Comverse Technology Inc.'s reported net loss is recorded as an adjustment to net loss for the purposes of calculating loss per share.

The calculation of loss per share attributable to Comverse Technology Inc.'s shareholders for the fiscal years ended January 31, 2011, 2010 and 2009 was as follows:

As a result of the Company's net loss attributable to Comverse Technology, Inc. during the fiscal years ended January 31, 2011, 2010 and 2009, the diluted loss per share attributable to Comverse Technology, Inc.'s shareholders computation excludes 0.9 million, 0.7 million and 1.1 million of contingently issuable shares, respectively, because the effect would be antidilutive.

The FASB's guidance requires contingently convertible instruments be included in diluted earnings per share, if dilutive, regardless of whether a market price trigger has been met. The Convertible Debt Obligations meet the definition of a contingently convertible instrument. The Convertible Debt Obligations were excluded from the computation of diluted earnings per share attributable to Comverse Technology, Inc.'s shareholders because the effect would be anti dilutive for the fiscal years ended January 31, 2011, 2010 and 2009.
