Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Performance Shares On February 17, 2016, the Company granted performance awards associated with the Company’s Class A stock to certain senior officers. The payment of performance shares, which will be satisfied with the issuance of shares out of treasury stock, is contingent upon the achievement of specific performance goals over a stated period of time. For the 2016 performance share grant, the total target number of performance shares granted is 331,500, and the maximum number of performance shares that may be earned is 663,000, which assumes 200% of the target shares originally granted. Target shares of 248,625 may be earned upon the achievement of three financial goals (“financial measure performance shares”) and target shares of 82,875 may be earned based on the Company’s total shareholder return relative to the S&P SmallCap 600 Index (“TSR performance shares”). No dividends are paid on these performance shares. The financial measure performance shares, which have a weighted average grant date fair value of $15.85, have a three-year performance period through December 31, 2018. These shares will cliff-vest after approval by the Compensation Committee, which will be no later than March 15, 2019, if not forfeited by the recipient. For each of the three financial measures, there are annual goals set in February of each year, with the total award payout based on a cumulative average of the 2016, 2017, and 2018 goals. Accordingly, the Company will remeasure the fair value of the 2016 financial measure performance shares each reporting period until the 2018 goals are set, after which the fair value will be fixed for the remaining performance period. As of second quarter-end 2016, the current fair value for financial measure performance shares was $18.02. The TSR performance shares also have a three-year performance period through December, 31 2018 and have an estimated fair value of $19.73, which was computed using a Monte Carlo simulation model incorporating assumptions for inputs of expected stock price volatility, dividend yield and risk-free interest rate. These shares will cliff-vest after approval by the Compensation Committee, which will be no later than March 15, 2019, if not forfeited by the recipient. For the second quarter 2016 and 2015, respectively, total compensation expense related to all performance shares totaled $0.8 million and $0.3 million, and the related tax benefit was $0.3 million and $0.1 million. For June year to date 2016 and 2015, respectively, total compensation expense related to all performance shares totaled $2.1 million and $0.3 million, and the related tax benefit was $0.8 million and $0.1 million.
