Stock-Based Compensation [Abstract]
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation Stock-based compensation expense is adjusted for estimated forfeitures and is recognized on a straight-line basis over the requisite service period of the award, which is generally three years for stock options and one to three years for restricted stock units and performance-based restricted stock units. The Company estimates future forfeiture rates based on its historical experience. See Footnote 15 for additional information. Stock Options The Company has issued both nonqualified and incentive stock options at exercise prices equal to the Company’s common stock price on the date of grant with contractual terms of ten years. Stock options issued by the Company generally vest and are expensed ratably over three years. For options granted prior to 2008, options become fully vested and are exercisable for one year following termination due to death, disability or retirement at age 65 or older. For options granted since the beginning of 2008, options fully vest and are exercisable for a period of time depending on the employee’s age and years of service in the case of retirement (as defined in the stock option agreement). Stock option grants are generally subject to forfeiture if employment terminates prior to vesting, except upon retirement, in which case the options may remain outstanding and exercisable for the remaining contractual term of the option. The Company has not granted stock options since 2011. Time-Based Restricted Stock Units Awards of time-based restricted stock units are independent of stock option grants and are generally subject to forfeiture if employment terminates prior to vesting. The awards generally cliff-vest in one to three years or vest ratably over three years from the date of grant. In the case of retirement (as defined in the award agreement), awards vest depending on the employee’s age and years of service. The time-based restricted stock units have rights to dividend equivalents payable in cash. The Company expenses the cost of restricted stock units ratably over the vesting period, net of estimated forfeitures. Performance-Based Restricted Stock Units Performance-based restricted stock unit awards represent the right to receive unrestricted shares of stock based on the achievement of Company performance objectives and/or individual performance goals established by the Organizational Development & Compensation Committee and the Board of Directors. The performance-based restricted stock units generally entitle recipients to shares of common stock equal to 0% up to 200% of the number of units granted at the vesting date, depending on the level of achievement of the specified market and performance conditions (“Performance-Based RSUs”). With respect to Performance-Based RSUs granted in all years other than 2015, the number of shares in which the participant vests is based on the Company’s total shareholder return relative to its peer group over a three-year period (“Relative TSR Metric”). For Performance-Based RSUs granted in 2015, the number of shares in which the participant will vest is based on three criteria, including the Relative TSR Metric, a sales growth metric and an earnings growth metric. Other performance-based restricted stock units entitle the recipient to shares of common stock if specified market and performance conditions are achieved and vest no earlier than one year from the date of grant and no later than seven years from the date of grant (“Stock-Price Based RSUs”). The grant date fair value of the Performance-Based RSUs subject to the Relative TSR Metric and certain Stock-Price Based RSUs is estimated using Monte Carlo simulation, with the primary input into such valuation being the expected future volatility of the Company’s common stock, and if applicable, the volatilities of the common stocks of the companies in the Company’s peer group, upon which the relative total shareholder return performance is measured. The fair values of these awards generally approximate the fair value of the Company’s common stock on the date of grant. For Performance-Based RSUs and Stock-Price Based RSUs whose vesting is dependent on a sales growth, earnings growth or other performance metric, the Company assesses the probability of achievement of such metrics each period and records expense for the awards based on the probable achievement of such metrics. Performance-based restricted stock units are not subject to the payment of dividend equivalents in the same manner as time-based restricted stock units. Rather, with respect to performance-based restricted stock units, dividend equivalents are credited to the recipient and are paid only to the extent the applicable performance criteria are met and the performance-based restricted stock units vest and the related stock is issued. In the case of retirement (as defined in the award agreement), awards vest depending on the employee’s age and years of service, subject to the satisfaction of the applicable performance criteria.

Stock Options

The Company has issued both nonqualified and incentive stock options at exercise prices equal to the Company’s common stock price on the date of grant with contractual terms of ten years. Stock options issued by the Company generally vest and are expensed ratably over three years. For options granted prior to 2008, options become fully vested and are exercisable for one year following termination due to death, disability or retirement at age 65 or older. For options granted since the beginning of 2008, options fully vest and are exercisable for a period of time depending on the employee’s age and years of service in the case of retirement (as defined in the stock option agreement). Stock option grants are generally subject to forfeiture if employment terminates prior to vesting, except upon retirement, in which case the options may remain outstanding and exercisable for the remaining contractual term of the option. The Company has not granted stock options since 2011.

Time-Based Restricted Stock Units

Awards of time-based restricted stock units are independent of stock option grants and are generally subject to forfeiture if employment terminates prior to vesting. The awards generally cliff-vest in one to three years or vest ratably over three years from the date of grant. In the case of retirement (as defined in the award agreement), awards vest depending on the employee’s age and years of service. The time-based restricted stock units have rights to dividend equivalents payable in cash. The Company expenses the cost of restricted stock units ratably over the vesting period, net of estimated forfeitures.

Performance-Based Restricted Stock Units

Performance-based restricted stock unit awards represent the right to receive unrestricted shares of stock based on the achievement of Company performance objectives and/or individual performance goals established by the Organizational Development & Compensation Committee and the Board of Directors. The performance-based restricted stock units generally entitle recipients to shares of common stock equal to 0% up to 200% of the number of units granted at the vesting date, depending on the level of achievement of the specified market and performance conditions (“Performance-Based RSUs”). With respect to Performance-Based RSUs granted in all years other than 2015, the number of shares in which the participant vests is based on the Company’s total shareholder return relative to its peer group over a three-year period (“Relative TSR Metric”). For Performance-Based RSUs granted in 2015, the number of shares in which the participant will vest is based on three criteria, including the Relative TSR Metric, a sales growth metric and an earnings growth metric.

Other performance-based restricted stock units entitle the recipient to shares of common stock if specified market and performance conditions are achieved and vest no earlier than one year from the date of grant and no later than seven years from the date of grant (“Stock-Price Based RSUs”).

The grant date fair value of the Performance-Based RSUs subject to the Relative TSR Metric and certain Stock-Price Based RSUs is estimated using Monte Carlo simulation, with the primary input into such valuation being the expected future volatility of the Company’s common stock, and if applicable, the volatilities of the common stocks of the companies in the Company’s peer group, upon which the relative total shareholder return performance is measured. The fair values of these awards generally approximate the fair value of the Company’s common stock on the date of grant. For Performance-Based RSUs and Stock-Price Based RSUs whose vesting is dependent on a sales growth, earnings growth or other performance metric, the Company assesses the probability of achievement of such metrics each period and records expense for the awards based on the probable achievement of such metrics.

Performance-based restricted stock units are not subject to the payment of dividend equivalents in the same manner as time-based restricted stock units. Rather, with respect to performance-based restricted stock units, dividend equivalents are credited to the recipient and are paid only to the extent the applicable performance criteria are met and the performance-based restricted stock units vest and the related stock is issued. In the case of retirement (as defined in the award agreement), awards vest depending on the employee’s age and years of service, subject to the satisfaction of the applicable performance criteria.
