Prior to 2013, in the absence of sufficient historical data, 50% of the assumed volatility was derived from the average volatility of common shares for similar companies over a period approximating the expected term of the options. The remaining 50% of the expected volatility was derived from the average volatility of the Company's common shares since their initial public offering in 2007.  Stock options granted in 2013 used 100% of the average volatility of the Company's stock over a period approximating the expected term of the options. The risk-free rate is based on daily U.S. Treasury yield curve with a term approximating the expected term of the option. No forfeiture was estimated on all options granted during the six months ended June 30, 2013 and 2012 as management believes that none of the grantees will leave the Company within the option vesting period.</div><div style="text-indent: 0pt; display: block;"> </div><div style="text-align: left; text-indent: 0pt; display: block; font-family: Times New Roman; margin-left: 0pt; font-size: 10pt; font-weight: bold; margin-right: 0pt;">Restricted Stock</div><div style="text-align: justify; text-indent: 0pt; display: block; margin-left: 0pt; margin-right: 0pt;"> </div><div style="text-align: left; text-indent: 27pt; display: block; font-family: Times New Roman; margin-left: 0pt; font-size: 10pt; margin-right: 0pt;">During the six months ended June 30, 2013, the Company granted 28,150 shares of restricted common stock valued at $0.7 million to certain employees. The restricted stock was valued based on the closing price of the Company's stock on the date of grant. The restricted stock has a vesting period of 4 years. As of June 30, 2013, none of the restricted stock granted during 2013 had vested. The Company recognized less than $0.1 million of stock compensation expense for each of the three and six months ended June 30, 2013 and none for the same periods in 2012. Unamortized stock compensation expense relating to restricted stock as of June 30, 2013 was $0.7 million to be recognized over 3.9 years.</div><div style="text-align: justify; text-indent: 0pt; display: block; margin-left: 0pt; margin-right: 0pt;"> </div><div style="text-align: justify; text-indent: 27pt; display: block; font-family: Times New Roman; margin-left: 0pt; font-size: 10pt; margin-right: 0pt;">Stock-based compensation expense is recorded as a component of marketing, general and administrative expense in the Company's consolidated statements of income.</div></div></div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for compensation-related costs for equity-based compensation, which may include disclosure of policies, compensation plan details, allocation of equity compensation, incentive distributions, equity-based arrangements to obtain goods and services, deferred compensation arrangements, employee stock ownership plan details and employee stock purchase plan details.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5047-113901 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5070-113901 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 505 -SubTopic 50 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6406099&loc=d3e25284-112666 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 123R -Paragraph 64, 65, A240 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
