Share-Based Payment Arrangement [Abstract]  
Summary of Nonvested (Restricted) Shares and Units Activity
We grant time-based and performance-based restricted shares or units. Except in limited cases, performance-based restricted shares and units are only granted to executive officers. All performance share awards only vest upon the attainment of certain financial and operational criteria as established and approved by our Board of Directors. The number of shares that may be issued to the award recipients may be greater or lesser than the target award amount depending on actual performance achieved as compared to the performance targets set forth in the awards.
