NOTE 16 – STOCK BASED COMPENSATION

The Company has stock based compensation plans as described below. Total compensation cost that has been charged against income for those plans was $161,000, $96,000, and $118,000 for 2013, 2012 and 2011. The total income tax benefit resulting from these charges was $54,000, $33,000 and $40,000, respectively.

The Firstbank Corporation Stock Compensation Plans of 1997 and 2006 (“Plans”), as amended, which were shareholder approved, provide for the grant of 593,798 and 315,000 shares of stock, respectively, in either restricted form or under option. Options may be either incentive stock options or nonqualified stock options. As of December 31, 2013 only nonqualified stock options and restricted stock shares have been issued under the plans. The 1997 Plan terminated April 28, 2007. The 2006 Plan will terminate February 27, 2016. The Board, at its discretion, may terminate any or all of the Plans prior to the Plans’ scheduled termination dates. At year end 2013, there were 48,994 shares available for grant under the 2006 Plan.

Stock Option

Each option granted under the Plans may be exercised in whole or in part during such period as is specified in the option agreement governing that option. Options may only be issued with exercise prices equal to, or greater than, the stock’s market value on the date of issuance. The length of time available for a stock option to be exercised is governed by each option agreement, but has not been more than ten years from the issuance date.

All companies are required to record compensation cost for stock options provided to employees in return for employee service. The cost is measured at the fair value of the options when granted. This cost is expensed over the employee service period, which is normally the vesting period of the options.

The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected volatilities are based on historical volatilities of our common stock. We use historical data to estimate option exercise and post-vesting termination behavior. The expected term of options granted is based on historical data and represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no options granted in 2011, 2012 or 2013.
