Compensation expense is based upon the number of shares expected to vest after assessing the probability that the performance criteria will be met. Compensation expense is recognized over the vesting period, adjusted for any changes in our probability assessment; ·                  PSUs subject to our total shareholder return, or TSR, market metric relative to a peer group of companies, which includes both market and service conditions, are estimated using a Monte Carlo simulation. Compensation expense is recognized over the applicable vesting period. All compensation cost for the award will be recognized if the requisite service period is fulfilled, even if the market condition is never satisfied; and, ·                  time vesting RSUs are based on the market value of our stock on the date of grant. Compensation expense for time vesting RSUs is recognized over the vesting period.   The vesting period for our stock awards is the requisite service period associated with each grant.   Our share-based compensation expense is comprised of the following:   <table style="text-align:left;TEXT-ALIGN: left;

The performance goals for the PSUs granted, which are accounted for as equity awards, are based upon the following performance measures: (i) our revenue growth over the performance period, (ii) our adjusted net income as a percent of sales at the end of the performance period, and (iii) our relative total shareholder return, or TSR, compared to a peer group of companies at the end of the performance period.   In 2013, approximately 253,000 PSUs subject to company specific performance metrics were granted with weighted average grant date fair value of $23.37 per share and approximately 28,000 PSUs subject to the TSR metric were granted with weighted average grant date fair value of $32.63 per share. The number of PSUs reflected as granted represents the target number of shares that are eligible to vest subject to the attainment of the performance goals. Depending on the outcome of these performance goals, a recipient may ultimately earn a number of shares greater or less than their target number of shares granted, ranging from 0% to 200% of the PSUs granted. Shares of our common stock are issued on a one-for-one basis for each PSU earned. Participants vest in their PSUs at the end of the performance period.   The fair value of the PSUs subject to company specific performance metrics is equal to the closing price of our common stock on the grant date.   The fair value of the market condition PSUs was determined using a Monte Carlo simulation and utilized the following inputs and assumptions:   <table style="text-align:left;TEXT-ALIGN: left;

As of June 30, 2013 there are approximately 357,141 shares available for issuance under this plan.   Previously under this plan, there were two plan periods:  January 1 through June 30 (Plan Period One) and July 1 through December 31 (Plan Period Two).   In November 2012, the plan was amended to revise Plan Period One to May 1 through October 31 and to revise Plan period Two to November 1 through April 30 along with minor administrative changes. The plan amendments are effective January 1, 2013 and provide an Initial Offering Period from January 1, 2013 through April 30, 2013.   For the Initial Offering Period in 2013, the fair value of approximately $60,700 was estimated using the Type B model with a risk free interest rate of 0.04%, volatility of 29.6% and an expected option life of 0.33 years.  This fair value was amortized over the four month period ending April 30, 2013.   For Plan Period One in 2013, the fair value of approximately $97,500 was estimated using the Type B model with a risk free interest rate of 0.08%, volatility of 28.00% and an expected option life of 0.50 years.  This fair value is being amortized over the six month period ending October 31, 2013.</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.
