Earnings Per Share. The table that follows presents our computation of weighted average basic and diluted shares outstanding, which we use in our earnings per share calculations. For each period presented, our net income allocable to both common shareholders and diluted common shareholders is the same as our net income in our consolidated statements of income.

We had been paying a quarterly cash dividend of $0.22 per share to our common shareholders since the second quarter of 2013. In April 2014, our Board of Directors increased our dividend to $0.27 per share, commencing with the dividend we paid in June 2014. Our latest $0.27 per share quarterly dividend was declared in October 2014 and is payable in December 2014.

Share-Based Compensation. We have no outstanding stock options and no future share-based compensation to be recognized pursuant to stock option grants.

We grant restricted units of our common stock to certain of our key executives, key employees and Chairman of the Board. We also grant shares of restricted stock to our other non-employee directors. The restricted units granted to our key executives and key employees generally vest in full on the third anniversary of the award date, conditional on continued employment. The restricted unit grants, including those granted to our Chairman, can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. The shares of restricted common stock we grant to our other non-employee directors vest in full on the first anniversary of the award date, conditional upon continued service as a director. Each grantee of shares of restricted stock is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The restricted stock units outstanding have no voting or dividend rights.

For each of the restricted stock units granted in 2012 through 2014, at the earlier of three years after grant or at termination of employment or service, the grantee will be issued a share of our common stock for each common stock unit vested. As of September 30, 2014 and December 31, 2013, respective totals of 827,366 and 960,290 shares of restricted stock or restricted stock units were outstanding.

We estimate that stock-based compensation cost not yet recognized related to shares of restricted stock or restricted stock units, based on their grant-date fair values, was $20 million at September 30, 2014. This expense is being recognized on a staged-vesting basis over three years for awards attributable to individuals meeting certain age and years-of-service requirements, and on a straight-line basis over the applicable vesting period of one or three years for the other awards.

Share Repurchase Plan. In February 2010, our Board of Directors approved a plan to repurchase up to 12 million shares of our common stock. Under this plan, we had repurchased 6.6 million shares of our common stock for $323 million through September 30, 2014. We repurchased 3.5 million shares for $237 million during the nine months ended September 30, 2014. We account for the shares we hold in treasury under the cost method, at average cost.
