Earnings Per Common Share and Share Awards

Basic earnings per common share is computed by dividing net income attributable to the Company by the weighted average number of common shares outstanding during the reporting period. Diluted earnings per common share is computed by dividing net income attributable to the Company by the combination of dilutive potential common stock, comprised of shares issuable under the Company’s share-based compensation plans and the weighted average number of common shares outstanding during the reporting period. Dilutive common share equivalents include the dilutive effect of in-the-money share-based awards, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, when share-based awards are exercised, (a) the exercise price of a share-based award; (b) the amount of compensation cost, if any, for future services that the Company has not yet recognized; and (c) the amount of estimated tax benefits that would be recorded in retained earnings, if any, are assumed to be used to repurchase shares in the current period. The number of incremental dilutive potential common shares, calculated using the treasury stock method, was 4,797 and 4,271 for the three months ended June 30, 2015 and 2014, respectively, and 5,160 and 5,221 for the six months ended June 30, 2015 and 2014, respectively.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30:



	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Net income attributable to the Company	$	4,120,497	$	3,373,598	$	5,846,621	$	4,360,036
Weighted average common shares outstanding – Basic	2,004,698		2,034,931		2,008,718		2,036,047
Incremental shares outstanding assuming the exercise of dilutive stock options and SARs (share-settled)	4,797		4,271		5,160		5,221
Weighted average common shares outstanding – Diluted	2,009,495		2,039,202		2,013,878		2,041,268
Basic earnings per common share	$	2.06	$	1.66	$	2.91	$	2.14
Diluted earnings per common share	$	2.05	$	1.65	$	2.90	$	2.14

There were 4,500 and 3,000 potential shares excluded from the computation of diluted earnings per share for the three months ended June 30, 2015 and 2014, respectively. There were 4,500 and no potential shares excluded from the computation of diluted earnings per share for the six months ended June 30, 2015 and 2014, respectively. These potential shares were anti-dilutive because the underlying share awards had strike prices that exceeded the fair market value.

The Company has adopted employee stock award plans under which restricted stock, and options or stock appreciation rights ("SARs") to acquire shares (not to exceed 500,000 shares) of the Company's stock, may be granted to key employees or directors of the Company at a price not less than the market value on the date of grant. SARs and options (which have predominantly been incentive stock options) awarded under the plans thus far generally expire in five to ten years from the date of grant and are exercisable and vest: immediately; within one year; or at 10% to 20% per year beginning on the date of grant. All SARs issued to date have been share-settled only.

A summary of share-based award transactions for all share-based award plans follows:



	Number Of Shares		Weighted Average Exercise Price		Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value
Outstanding as of January 1, 2014	19,000		$	45.74	3.43	$	669,610
SARs granted	4,500		68.70
SARs exercised	(1,500	)	49.04
Options exercised	(1,000	)	27.21
Options/SARs canceled/forfeited/expired	—		—
Outstanding as of December 31, 2014	21,000		$	51.30	3.64	$	453,510
SARs granted	4,500		73.00
SARs exercised	(2,000	)	47.88
Options exercised	(1,500	)	36.79
Options/SARs canceled/forfeited/expired	—		—
Outstanding as of June 30, 2015	22,000		$	57.04	4.43	$	316,230
Exercisable as of June 30, 2015	18,625		$	54.15	3.99	$	316,230

During the second quarters of both 2015 and 2014, the Company issued a total of 4,500 share-settled SARs to the directors of the Company. SARs give the holder the right to receive stock equal to the appreciation in the value of shares of stock from the grant date for a specified period of time, and as a result, are accounted for as equity instruments. The fair value of each award is estimated on the date of grant using the Black-Scholes option valuation model with the weighted average assumptions noted in the table shown below. Expected volatilities are based on both the implied and historical volatility of the Company's stock. The Company uses historical data to project SAR exercises and pre-exercise forfeitures within the valuation model. The expected term of awards represents the period of time that SARs granted are expected to be outstanding. The interest rate assumed for the expected life of the award is based on the U.S. Treasury yield curve at the time of the grant. The weighted average fair values for the SARs issued during 2015 and 2014 were $31.16 and $28.98, respectively.

The weighted average fair values for SARs issued during 2015 and 2014 were estimated using the weighted average assumptions shown in the table below:



	2015		2014
Expected life in years	7.0		6.9
Volatility	40.7	%	39.9	%
Interest rate	2.0	%	2.1	%
Yield rate	0.4	%	0.4	%

There was approximately $68,000 and $55,000 of compensation expense relating to SARs or options vesting on or before June 30, 2015 and 2014, respectively, included in salaries, employee benefits and payroll taxes in the Consolidated Statements of Income. As of June 30, 2015, there was approximately $105,000 of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the Company’s stock award plans. That cost is expected to be recognized over a period of approximately 6 months based on weighted average durations.

There have been no stock options or SARs granted where the exercise price was less than the market price on the date of grant.
