Shareholders' Equity and Share-based Payments

EARNINGS (LOSS) PER SHARE, SHARE-BASED COMPENSATION AND SHARE REPURCHASE PLAN

Earnings (Loss) per Share. For each period presented, the only difference between our calculated weighted-average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. In periods where we have a net loss, the effect of our outstanding restricted stock units is anti-dilutive, and therefore does not increase our diluted shares outstanding.

For each period presented, our net income (loss) allocable to both common shareholders and diluted common shareholders is the same as our net income (loss) in our consolidated statements of operations.

Share-Based Compensation. Annually, the Compensation Committee granted restricted units of our common stock to certain of our key executives and employees and restricted common stock to our nonemployee directors. The restricted stock 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 stock unit grants can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. The grants of restricted stock to our nonemployee directors were scheduled to vest in full on the first anniversary of the award date, conditional upon continued service as a director, except for the 2021 grant to one director who retired from our board of directors as of the date of our annual meeting of shareholders in May 2021, which vested on that date. 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 2020 through June 30, 2022, at the earlier of three years after grant or at termination of employment or service, the grantee will be issued one share of our common stock for each unit vested. As of June 30, 2022 and December 31, 2021, respective totals of 2,602,915 and 2,447,259 shares of restricted stock and restricted stock units were outstanding.

We estimate that share-based compensation cost not yet recognized related to shares of restricted stock or restricted stock units, based on their grant-date fair values, was $17 million as of June 30, 2022. This expense is being recognized on a graded-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 December 2014, our Board of Directors approved a share repurchase program under which we may repurchase up to 10 million shares of our common stock on a discretionary basis. Under the program, which has no expiration date, we had repurchased 2.0 million shares for $100 million through December 31, 2015. We have not repurchased any shares under this plan since 2015, and are not obligated to make any future repurchases. We account for the shares we hold in treasury under the cost method, at average cost.
