Note 6.   Share-Based Payments

The Company maintains an equity incentive plan (the "2012 Equity Incentive Plan") that provides for grants of stock options, restricted shares, stock-based performance units and certain other types of stock-based awards.  The Company also maintains an equity incentive plan (the "2007 Equity Incentive Plan") and a stock incentive plan (the "1992 Incentive Stock Plan") that previously provided for grants of stock options, restricted shares and certain other types of stock-based awards.  Under the 2012 Equity Incentive Plan, which has a ten-year term, the maximum number of shares available for grants or awards is an aggregate of 2,500,000.  There will be no further grants under the 2007 Equity Incentive Plan or the 1992 Incentive Stock Plan.  At December 31, 2014, there were 1,496,798 shares reserved for future issuance under the 2012 Equity Incentive Plan. All plans are administered by the Compensation Committee of the Board of Directors.

The option price for each stock option granted under any of the plans may not be less than the fair market value of the Company's common stock on the date of grant.  Outstanding stock options are generally exercisable in one-third increments upon the attainment of pre-defined levels of appreciation in the market value of the Company's Class A Common Stock.  In addition, options generally vest in one-third increments after three, four and five years, respectively, from the grant date (but, in any event, not until the attainment of the market value thresholds).  The options expire on the earlier of ten years from the date of grant, upon employment termination, or within specified time limits following voluntary employment termination (with the consent of the Company), retirement or death.  The Company generally settles employee stock option exercises with treasury shares.

With respect to outstanding restricted share grants, for grants made prior to fiscal 2013, generally one-half of the shares vest on the third anniversary of the grant, with the remaining one-half of the shares vesting in one-third increments upon attainment of pre-defined levels of appreciation in the market value of the Company's Class A Common Stock.  For grants made in and after fiscal 2013, generally one-half of the shares vest on the third anniversary of the grant, one-quarter of the shares vest in one-third increments upon the attainment of pre-defined levels of adjusted earnings per share, and the remaining one-quarter of the shares vest in one-third increments upon attainment of pre-defined levels of appreciation in the market value of the Company's Class A Common Stock.  Additionally, restricted shares cannot vest until the first anniversary of the grant date.  Unvested restricted shares generally expire on the earlier of five years from the date of grant, upon employment termination, or within specified time limits following voluntary employment termination (with the consent of the Company), retirement or death.  The Company issues restricted shares from treasury shares.

For the three-month periods ended December 31, 2014 and 2013, total stock-based compensation cost totaled $2,525 and $1,574, respectively.  The associated future income tax benefit recognized was $985 and $614 for the three-month periods ended December 31, 2014 and 2013, respectively.

For the three-month periods ended December 31, 2014 and 2013, the amount of cash received from the exercise of stock options was $3,727 and $1,855, respectively.  In connection with these exercises, the tax benefits realized by the Company for the three-month periods ended December 31, 2014 and 2013 were $315 and $177, respectively.

The transactions for restricted stock for the three months ended December 31, 2014 were as follows:

As of December 31, 2014, the total unrecognized compensation cost related to unvested restricted stock was $13,585 and is expected to be recognized over a weighted average period of 2.1 years.

The transactions for shares under options for the quarter ended December 31, 2014 were as follows:

No options vested during the three months ended December 31, 2014 and 2013, respectively.  The intrinsic value of options (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) exercised during the three-month periods ended December 31, 2014 and 2013 was $841 and $488, respectively.

The transactions for non-vested options for the quarter ended December 31, 2014 were as follows:

The fair value of each restricted stock grant is estimated on the date of grant using a binomial lattice valuation model.  The following table indicates the assumptions used in estimating fair value of restricted stock granted during the periods ended December 31, 2014 and 2013.

The risk-free interest rate is based on United States Treasury yields at the date of grant. The dividend yield is based on the most recent dividend payment and average stock price over the 12 months prior to the grant date.  Expected volatilities are based on the historical volatility of the Company's stock price.  The expected term for grants in the years ended September 30, 2014, 2013 and 2012 represents an estimate of the average period of time for restricted shares to vest.  The option characteristics for each grant are considered separately for valuation purposes.

The Company maintains the 1994 Director Fee Plan, and, after approval by the Company's shareholders in February 2014, the 2014 Director Fee Plan (collectively, the "Director Fee Plans").  After adoption of the 2014 Director Fee Plan, there will be no further fees or share-based awards under the 1994 Director Fee Plan.  Under the 2014 Director Fee Plan, directors (except for the Chairman of the Board) who are not also officers of the Company each receive, as an annual retainer fee for fiscal 2015, either cash or shares of the Company's Class A Common Stock with a value equal to $75.  The annual retainer fee for fiscal 2015, paid to a non-employee Chairman of the Board is $175.  Where the annual retainer fee is provided in shares, each director may elect to be paid these shares on a current basis or have such shares credited to a deferred stock account as phantom stock, with such shares to be paid to the director subsequent to leaving the Board.  The value of deferred shares is recorded in other liabilities.  A total of 17,005 shares had been deferred under the Director Fee Plans at December 31, 2014.  Additionally, directors who are not also officers of the Company each receive an annual stock-based grant (non-statutory stock options, stock appreciation rights and/or restricted shares) with a value of $110 for fiscal 2015.  A total of 22,300 stock options have been granted under the Director Fee Plans.  At December 31, 2014, there were no options outstanding. Additionally, 120,503 shares of restricted stock have been granted under the Director Fee Plans, 37,457 of which were unvested at December 31, 2014.  A total of 150,000 shares have been authorized to be issued under the 2014 Director Fee Plan.
