(a) We have deferred compensation plans for directors and certain of our employees.  Amounts owed to participants are denominated in common stock units.  Each unit represents one share of common stock.  The number of shares used to calculate basic earnings per share includes the weighted-average units credited to employees and directors under the deferred compensation plans.  Additionally, nonvestedunits are also included in the computation of basic weighted average shares when the requisite service period has been completed.  Accordingly, basic and diluted shares include weighted-average units of 0.5 million in 2014, 0.6 million in 2013 and 0.9 million in 2012.
