BASIS OF PRESENTATION

1. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, condensed consolidated financial statements do not include all of the information and footnotes required by US GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. All significant intercompany transactions have been eliminated in consolidation. Operating results for the three and six months ended June 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012.

The balance sheet at December 31, 2011 is consistent with the audited financial statements at that date but does not include all of the information and footnotes required by US GAAP for a complete set of financial statements. For further information, refer to the consolidated financial statements and footnotes thereto for the year ended December 31, 2011 (included in the Company’s Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 28, 2012).

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

Income Taxes

6 Months Ended

Income Taxes [Abstract]

INCOME TAXES

2. INCOME TAXES

Income taxes are accounted for using the asset and liability method, whereby deferred tax assets and liabilities are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities measured at tax rates that will be in effect for the year in which the differences are expected to affect taxable income.

During the six months ended June 30, 2012 and 2011, the Company recorded a provision for income taxes of $2.6 million and $2.3 million, respectively. The Company’s effective tax rate for the six months ended June 30, 2012 and 2011 was 40.1% and 41.0%, respectively. The Company’s effective tax rate primarily reflects the statutory corporate income tax rate, the net effect of state taxes, and the effect of various immaterial permanent tax differences.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

The fair value of stock options granted during the six months ended June 30, 2011 was estimated using the Black Scholes option pricing model, with the assumptions as follows:

Earnings Per Share

Earnings Per Share [Abstract]

EARNINGS PER SHARE

4. EARNINGS PER SHARE

Basic earnings per share is computed by dividing the net income available to common shareholders for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares, composed of incremental common shares issuable upon the exercise of stock options and restricted share units subject to vesting are included in diluted earnings per share only to the extent these shares are dilutive. Common equivalent shares are dilutive when the average market price during the period exceeds the exercise price of the underlying shares. The total number of common equivalent shares excluded from the calculations of diluted earnings per share, due to their anti-dilutive effect, was approximately 0.1 million for both the three and six months ended June 30, 2012, respectively, and approximately 0.4 million for both the three and six months ended June 30, 2011.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2012 and 2011 (in thousands, except per share data):

Content Rights and Deferred Service Credits [Abstract]

CONTENT RIGHTS AND DEFERRED SERVICE CREDITS

9. CONTENT RIGHTS AND DEFERRED SERVICE CREDITS

During 2012, the Company entered into a renewal agreement with a customer in which the Company was provided continued rights to distribute and resell courseware owned by the customer. In exchange for the receipt of an exclusive license to distribute and resell this courseware, the Company will provide the customer with service credits that can be exchanged for future purchases of the Company’s products and services. The value assigned to the content rights and the deferred service credits was $500,000, which represents the estimated fair value of the assets relinquished. The content rights are classified within other prepaid expenses and other assets, and the deferred service credits are classified within accrued liabilities and other long-term liabilities on our condensed consolidated balance sheets.

These exchangeable service credits will be issued annually through December 31, 2016, and will expire twenty-four months after issuance. Any unused credits will be forfeited upon expiration. During 2012, the Company has issued exchangeable service credits of $100,000 in accordance with this agreement, and is obligated to issue remaining service credits of $100,000 annually through 2016. The content rights are being amortized on a straight-line basis through December 31, 2016. Revenues for products or services provided in exchange for these service credits will be recognized in accordance with the Company’s revenue recognition policies.
