Dividends On April 13, 2015, our board of directors declared a dividend of $0.28 per share of common stock. This dividend is to be paid in cash on May 26, 2015 to shareholders of record at the close of business on April 28, 2015. Since 2011, we have paid quarterly dividends. Our board of directors expects to continue paying quarterly dividends, provided the future determination as to payment of dividends will depend on the financial needs of the Company and such other factors as deemed relevant by the board of directors. The following table presents the dividends either paid previously or declared by our board of directors for future payment:

First quarter | $ | 0.28 |  |  | 0.25 |

All of the options in the tables above vest and become exercisable over a period of up to eight years. Each option will terminate approximately nine years after the date of grant. The fair value of each share-based option is estimated on the date of grant using a Black-Scholes valuation method that uses the assumptions listed above. The risk-free interest rate is based on the U.S. Treasury rate over the expected life of the option at the time of grant. The expected life is the average length of time over which we expect the employee groups will exercise their options, which is based on historical experience with similar grants. The dividend yield is estimated over the expected life of the option based on our current dividend payout, historical dividends paid, and expected future cash dividends. Expected volatilities are based on the movement of our stock over the most recent historical period equivalent to the expected life of the option. Compensation expense equal to the grant date fair value is recognized for all of these awards over the vesting period. The stock-based compensation expense for the three-month periods ended March 31, 2015 and 2014 was $1,620 and $1,380, respectively. Unrecognized compensation expense related to outstanding unvested stock options as of March 31, 2015 was $14,440 and is expected to be recognized over a weighted average period of 4.52 years. Any future changes in estimated forfeitures will impact this amount. Earnings Per Share The following tables present a reconciliation of the denominators used in the computation of basic and diluted earnings per share and a summary of the options to purchase shares of common stock which were excluded from the diluted earnings calculation because they were anti-dilutive:
| Three-month Period
Reconciliation | 2015 |  | 2014
Basic weighted average shares outstanding | 295,237,625 |  |  | 296,641,994 |
Weighted shares assumed upon exercise of stock options | 699,093 |  |  | 853,176 |
Diluted weighted average shares outstanding | 295,936,718 |  |  | 297,495,170 |
| Three-month Period
Summary of Anti-dilutive Options Excluded | 2015 |  | 2014
Options to purchase shares of common stock | 2,066,000 |  |  | 1,292,528 |
Weighted average exercise prices of options | $ | 54.82 |  |  | $ | 54.00 |
Any dilutive impact summarized above relates to periods when the average market price of our stock exceeded the exercise price of the potentially dilutive option securities then outstanding.
