Earnings Per Share [Abstract] |
COMPUTATION OF EARNINGS PER SHARE | NOTE E – COMPUTATION OF EARNINGS PER SHARE Basic earnings per share were computed by dividing Net income by the weighted-average number of common shares outstanding for each respective period. Diluted earnings per share were calculated by dividing Net income by the weighted-average of all potentially dilutive common stock that were outstanding during the periods presented. The calculation of basic and diluted earnings per share for the three month periods ended March 31, 2014 and 2013 was as follows:
|  | For the three month period ended March 31 |
|  | 2014 |  |  | 2013 |
Numerator |  |  |  |  |  |  |  |
Net income |  | $ | 2,738 |  |  | $ | 4,965 |
Denominator |  |  |  |  |  |  |  |
Determination of shares |  |  |  |  |  |  |  |
Weighted-average common shares outstanding |  |  | 5,392 |  |  |  | 5,377 |
Dilutive effect - share-based awards |  |  | 39 |  |  |  | 80 |
Diluted weighted-average common shares outstanding |  |  | 5,431 |  |  |  | 5,457 |
Earnings per common share attributable to PLPC shareholders |  |  |  |  |  |  |  |
Basic |  | $ | 0.51 |  |  | $ | 0.92 |
Diluted |  | $ | 0.50 |  |  | $ | 0.91 |
For the three month periods ended March 31, 2014 and 2013, 17,000 and 0 stock options, respectively, were excluded from the calculation of diluted earnings per shares as they were anti-dilutive because the average market price was lower than the exercise price plus any unearned compensation on unvested options. For the three month periods ended March 31, 2014 and 2013, 55,312 and 2,058 restricted shares, respectively, were excluded from the calculation of diluted earnings per shares as they were anti-dilutive because the average market price was lower than the exercise price plus any unearned compensation on unvested options.
