Capital Transactions | (7)Capital Transactions Dividends The declaration of future dividends is subject to the discretion of the Company’s Board of Directors and will depend upon various factors, including the Company’s earnings, financial condition, restrictions imposed by any indebtedness that may be outstanding, cash requirements, future prospects and other factors deemed relevant by its Board of Directors. On March 17, 2014, the Company announced a cash dividend of $0.10 per common share in an aggregate amount of $1,618 that was paid on April 7, 2014, to shareholders of record on March 28, 2014. On May 7, 2014, the Company announced a cash dividend of $0.10 per common share in an aggregate amount of $1,619 that was paid on June 2, 2014, to shareholders of record on May 21, 2014. On August 6, 2014, the Company announced a cash dividend of $0.10 per common share in an aggregate amount of $1,619 that was paid on August 29, 2014, to shareholders of record on August 18, 2014. On August 27, 2014, the Company announced a special non-recurring cash dividend of $1.50 per common share in an aggregate amount of $28,501 that was paid on September 19, 2014, to shareholders of record on September 8, 2014. Share Repurchase Program On August 8, 2013, the Board of Directors authorized a $10,000 share repurchase program to be implemented over two years. Such purchases may be made in the open market, through block trades, in privately negotiated transactions or otherwise. The timing and amount of any shares repurchased will be determined based on the Company’s evaluation of market conditions and other factors and the program may be discontinued or suspended at any time. At September 30, 2014, the remaining balance available for repurchases under the program was $4,723. The following is a summary of the Company’s repurchases of common shares during the three and nine months ended September 30, 2014:
Period |  | Number of Shares |  | Average Price Paid per Share |  | Program Balance Used for Repurchases |
July 1 — September 30, 2014 |  | 177 |  | $ | 15.49 |  | $ | 2,731 |
Share-Based Compensation Stock option activity for the period ended September 30, 2014, is as follows:
|  | Number of Shares |  | Weighted Average Exercise Price Per Share |
Options outstanding at December 31, 2013 |  | 1,926 |  | $ | 12.54 |
Granted |  | 258 |  | 15.38 |
Expired |  | (18 | ) | 13.55 |
Exercised |  | (44 | ) | 7.32 |
Options outstanding at September 30, 2014 |  | 2,122 |  | 12.97 |
The Company’s outstanding stock options include time-based stock options, which vest over differing periods ranging from the date of issuance up to 48 months from the option grant date; performance-based stock options, which have already vested upon achieving operating income margins of six, eight and ten percent as reported in four of five consecutive quarters over the term of the options; performance-based stock options, which vest upon achieving cumulative annual net sales revenue growth targets over a rolling two-year period, subject to the Company maintaining at least an eight percent operating income margin during the applicable period; and performance-based stock options, which vest upon achieving annual net sales targets over a rolling one-year period. During the nine-month period ended September 30, 2014, the Company issued time-based stock options to purchase 258 shares of common stock under the 2012 Stock Incentive Plan to the Company’s executive officers and other employees. These options were issued with a weighted-average exercise price of $15.38 per share and a weighted-average grant date fair value of $6.53 per share. All of the options issued have an option termination date of ten years from the option grant date. The fair value of each option grant was estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted average assumptions for the nine-month period ended September 30, 2014:
|  | 2014 |
Expected life (in years) |  | 6.0 |
Risk-free interest rate |  | 1.5 |
Expected volatility |  | 56.7 |
Dividend yield |  | 2.6 |
Expected option lives and volatilities are based on historical data of the Company. The risk-free interest rate is calculated as the average U.S. Treasury bill rate that corresponds with the option life. The dividend yield is based on the Company’s historical and expected amount of dividend payouts, at the time of grant. On August 29, 2013, and September 19, 2014, the Company paid special non-recurring cash dividends of $1.50 per common share. The Company has excluded these special non-recurring cash dividends from the dividend yield used in the Black-Scholes option-pricing model calculations as it is not representative of future dividends to be declared by the Company. Share-based compensation expense from time-based stock options for the three-month periods ended September 30, 2014, and 2013, was approximately $691 and $620, respectively; the related tax benefit was approximately $273 and $245, respectively. Share-based compensation expense from time-based stock options for the nine-month periods ended September 30, 2014, and 2013, was approximately $2,307 and $2,423, respectively; the related tax benefit was approximately $911 and $957, respectively. As of September 30, 2014, and December 31, 2013, the unrecognized share-based compensation expense related to the grants described above was $2,627 and $3,294, respectively. As of September 30, 2014, the remaining compensation cost is expected to be recognized over the weighted-average period of approximately 1.8 years. The Company has not recognized any share-based compensation expense related to the net sales revenue performance-based stock options for the nine-month period ended September 30, 2014. Should the Company attain all of the net sales revenue metrics related to the net sales revenue performance-based stock option grants, the Company would recognize up to $800 of potential share-based compensation expense. At September 30, 2014, the aggregate intrinsic value of outstanding stock options to purchase 2,212 shares of common stock, exercisable stock options to purchase 1,095 shares of common stock and stock options to purchase 849 shares of common stock that are expected to vest was $7,546, $5,656 and $1,795, respectively. At December 31, 2013, the aggregate intrinsic value of outstanding options to purchase 1,926 shares of common stock, the exercisable options to purchase 838 shares of common stock, and options to purchase 905 shares of common stock expected to vest was $9,415, $6,069 and $3,179, respectively. Restricted stock unit activity for the period ended September 30, 2014 is as follows:
|  | Number of Shares |  | Weighted Average Grant Date Fair Value |
Units outstanding at December 31, 2013 |  | 32 |  | $ | 12.47 |
Granted |  | 156 |  | 10.65 |
Issued |  | — |  | — |
Forfeited |  | (7 | ) | 15.38 |
Units outstanding at September 30, 2014 |  | 181 |  | 12.16 |
During the nine-month period ended September 30, 2014, the Company issued 156 restricted stock units (RSUs) of common stock under the 2012 Incentive Plan to the Company’s Board of Directors, executive officers and other employees. The RSUs were issued with a weighted-average grant date fair value of $10.65 per share and vest in annual installments over a four year period from the grant date. RSUs are valued at the market value on the date of grant, which is the grant date share price discounted for expected dividend payments during the vesting period. For RSUs with post-vesting restrictions, a Finnerty Model was utilized to calculate a valuation discount from the market value of common shares reflecting the restriction embedded in the RSUs preventing the sale of the underlying shares over a certain period of time. The Finnerty Model proposes to estimate a discount for lack of marketability such as transfer restrictions by using an option pricing theory. This model has gained recognition through its ability to address the magnitude of the discount by considering the volatility of a company’s stock price and the length of restriction. The concept underpinning the Finnerty Model is that restricted stock cannot be sold over a certain period of time. Using assumptions previously determined for the application of the option pricing model at the valuation date, the Finnerty Model discount for lack of marketability is approximately 17.5 percent for a common share. Share-based compensation expense from RSUs for the three-month periods ended September 30, 2014, and 2013, was approximately $261 and $49, respectively; the related tax benefit was approximately $103 and $19, respectively. Share-based compensation expense from RSUs for the nine-month periods ended September 30, 2014, and 2013, was approximately $727 and $176, respectively; the related tax benefit was approximately $287 and $70, respectively. As of September 30, 2014, and December 31, 2013, the unrecognized share-based compensation expense related to the grants described above was $1,117 and $62, respectively. As of September 30, 2014, the remaining compensation expense is expected to be recognized over the weighted average period of approximately 2.0 years.
