The decrease in goodwill is related to the sale of certain assets related to the Company’s pay-per-click advertising services in July 2013.

The Company reviews goodwill for impairment annually on November 30 and more frequently whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. The testing of goodwill and other intangible assets for impairment requires the Company to make significant estimates about its future performance and cash flows, as well as other assumptions. These estimates can be affected by numerous factors, including changes in economic, industry or market conditions, changes in business operations, changes in competition or changes in the share price of the Company’s common stock and market capitalization. Significant and sustained declines in the Company’s stock price and market capitalization, a significant decline in its expected future cash flows or a significant adverse change in the Company’s business climate, among other factors, could result in the need to perform an impairment analysis in future interim periods. The Company cannot accurately predict the amount and timing of any future impairment of goodwill or other intangible assets. Should the value of goodwill or other intangible assets become impaired, the Company would record an impairment charge, which could have an adverse effect on its financial condition and results of operations.

The current business environment is subject to evolving market conditions and requires significant management judgment to interpret the potential impact to our assumptions. To the extent that changes in the current business environment impact the Company’s ability to achieve levels of forecasted operating results and cash flows, or should other events occur indicating the remaining carrying value of its assets might be impaired, the Company would test its goodwill and intangible assets for impairment and may recognize an additional impairment loss.
