STOCK-BASED COMPENSATION [Abstract] 
STOCK-BASED COMPENSATION
7.       STOCK-BASED COMPENSATION

The Company has no stock-based compensation plans of its own; however, Employers Mutual has several stock plans which utilize the common stock of the Company.  Employers Mutual can provide the common stock required under its plans by: 1) using shares of common stock that it currently owns; 2) purchasing common stock on the open market; or 3) directly purchasing common stock from the Company at the current fair value.  Employers Mutual has historically purchased common stock from the Company for use in its stock option plans and its non-employee director stock purchase plan.  Employers Mutual generally purchases common stock on the open market to fulfill its obligations under its employee stock purchase plan.

Employers Mutual maintains three separate stock option plans for the benefit of officers and key employees of Employers Mutual and its subsidiaries.  A total of 1,000,000 shares of the Company's common stock have been reserved for issuance under the 1993 Employers Mutual Casualty Company Incentive Stock Option Plan (1993 Plan), a total of 1,500,000 shares have been reserved for issuance under the 2003 Employers Mutual Casualty Company Incentive Stock Option Plan (2003 Plan) and a total of 2,000,000 shares have been reserved for issuance under the 2007 Employers Mutual Casualty Company Stock Incentive Plan (2007 Plan).
 
The 1993 Plan and the 2003 Plan permit the issuance of incentive stock options only, while the 2007 Plan permits the issuance of performance shares, performance units, and other stock-based awards, in addition to qualified (incentive) and non-qualified stock options, stock appreciation rights, restricted stock and restricted stock units.  All three plans provide for a ten-year time limit for granting awards.  Options can no longer be granted under the 1993 Plan and no additional options will be granted under the 2003 Plan now that Employers Mutual is utilizing the 2007 Plan.  Options granted under the plans generally have a vesting period of five years, with options becoming exercisable in equal annual cumulative increments commencing on the first anniversary of the option grant.  Option prices cannot be less than the fair value of the common stock on the date of grant.

The Senior Executive Compensation and Stock Option Committee (the “Committee”) of Employers Mutual's Board of Directors (the “Board”) grants the awards and is the administrator of the plans.  The Company's Compensation Committee must consider and approve all awards granted to the Company's executive officers.

The Company recognized compensation expense from these plans of $39,229 ($28,280 net of tax) and $27,978 ($23,844 net of tax) for the three months and $150,802 ($108,000 net of tax) and $112,054 ($91,374 net of tax) for the nine months ended September 30, 2011 and 2010, respectively.  No compensation expense was recognized during the three months or nine months ended September 30, 2011 and 2010 related to a separate stock appreciation rights agreement that is accounted for as a liability-classified award, because the fair value of the award did not exceed the floor amount contained in the agreement.  During the first nine months of 2011, 302,180 non-qualified stock options were granted under the 2007 Plan to eligible participants at a price of $24.405.  During the nine months ended September 30, 2011, 33,031 options were exercised under the plans at prices ranging from $11.38 to $20.68.

The weighted average fair value of options granted during the nine months ended September 30, 2011 and 2010 amounted to $4.44 and $1.77, respectively.  Employers Mutual estimated the fair value of each option grant on the date of grant using the Black-Scholes-Merton option-pricing model and the following weighted-average assumptions:

   
2011
  
2010
 
Weighted-average dividend yield
  3.11%  3.47%
Expected volatility
  20.9% - 51.2%  16.7% - 23.6%
Weighted-average volatility
  32.76%  19.17%
Risk-free interest rate
  0.17% - 2.75%  0.16% - 2.99%
Expected term (years)
  0.25 - 6.40   0.25 - 6.30 
 
The expected term of the options granted in 2011 to individuals who will not be eligible to retire prior to the completion of the normal vesting period was estimated using historical data that excluded certain option exercises that occurred prior to the normal vesting period due to the retirement of the option holders.  The expected term of options granted to individuals who are, or will be, eligible to retire prior to the completion of the normal vesting period has been adjusted to reflect the potential accelerated vesting period.  This produced a weighted-average expected term of 2.99 years.

The expected volatility of options granted in 2011 was computed by using the historical daily prices of the Company's common stock for a period covering 6.4 years, which approximates the average term of the options.  This produced an expected volatility of 43.7 percent for individuals who will not be eligible to retire prior to the completion of the normal vesting period.  The expected volatility of options granted to individuals who are, or will be, eligible to retire prior to the completion of the normal vesting period was computed by using the historical daily prices for the period approximating the expected term of those options.  This produced expected volatility ranging from 20.9 percent to 51.2 percent.  The weighted-average volatility of the 2011 option grant was 32.76 percent.  Prior to 2011, expected volatilities were calculated, in most instances, using historical high and low average monthly prices of the Company's common stock.  This produced expected volatilities that were typically lower than those calculated in 2011 using daily prices.  Due to the higher expected volatilities used in the valuation of the 2011 option grant, the fair values of the granted options are higher, which produces a larger amount of stock compensation expense.
