Tanger Factory Outlet Centers, Inc [Member] |
Earnings Per Share of the Company | Earnings Per Share of the Company The following table sets forth a reconciliation of the numerators and denominators in computing the Company's earnings per share (in thousands, except per share amounts):
|  | Three months ended March 31,
|  | 2013 |  | 2012
Numerator |  |  |  |
Net income attributable to Tanger Factory Outlet Centers, Inc. |  | $ | 15,439 |  |  | $ | 8,128 |
Less allocation of earnings to participating securities |  | (194 | ) |  | (158 | )
Net income available to common shareholders of Tanger Factory Outlet Centers, Inc. |  | $ | 15,245 |  |  | $ | 7,970 |
Denominator |  |  |  |
Basic weighted average common shares |  | 93,132 |  |  | 89,671 |
Effect of notional units |  | 805 |  |  | 1,096 |
Effect of outstanding options and restricted common shares |  | 106 |  |  | 65 |
Diluted weighted average common shares |  | 94,043 |  |  | 90,832 |
Basic earnings per common share: |  |  |  |
Net income |  | $ | 0.16 |  |  | $ | 0.09 |
Diluted earnings per common share: |  |  |  |
Net income |  | $ | 0.16 |  |  | $ | 0.09 |
The notional units are considered contingently issuable common shares and are included in earnings per share if the effect is dilutive using the treasury stock method. The computation of diluted earnings per share excludes options to purchase common shares when the exercise price is greater than the average market price of the common shares for the period. For the three months ended March 31, 2013, no options were excluded from the computation. For the three months ended March 31, 2012, 174,600 options were excluded from the computation. The assumed exchange of the partnership units held by the noncontrolling interest limited partners as of the beginning of the year, which would result in the elimination of earnings allocated to the noncontrolling interest in the Operating Partnership, would have no impact on earnings per share since the allocation of earnings to a partnership unit, as if exchanged, is equivalent to earnings allocated to a common share. Certain of the Company's unvested restricted common share awards contain non-forfeitable rights to dividends or dividend equivalents. The impact of these unvested restricted common share awards on earnings per share has been calculated using the two-class method whereby earnings are allocated to the unvested restricted common share awards based on dividends declared and the unvested restricted common shares' participation rights in undistributed earnings. Unvested restricted common shares that do not contain non-forfeitable rights to dividends or dividend equivalents, are included in the diluted earnings per share compilation if the effect is dilutive, using the treasury stock method.
