We allocate goodwill to our reporting units and perform our annual impairment test during the fourth quarter of our fiscal year, or earlier if indicators of potential impairment exist. For the purposes of completing our impairment test, we perform either a qualitative or a quantitative analysis on a reporting unit basis. We utilized a quantitative analysis to complete our most recent annual impairment test during the fourth quarter of fiscal year 2014 and concluded that there was no impairment, as the fair value of our reporting units exceeded their carrying values.

In a qualitative analysis, we evaluate factors including, but not limited to, macro-economic conditions, market and industry conditions, the competitive environment, the operational stability and the overall financial performance of the reporting units, including cost factors and actual revenue results. For reporting units in which the qualitative assessment concludes it is more likely than not that the fair value is more than its carrying value, no further goodwill impairment testing is required.

For those reporting units where a significant change or event has occurred, where potential impairment indicators exist, or for which we have not performed a quantitative assessment recently, we utilize a two-step quantitative assessment to testing goodwill for impairment. The first step tests for possible impairment by applying a fair value-based test by weighing the results from the income approach and the market approach. These valuation approaches consider a number of factors that include, but are not limited to, prospective financial information, growth rates, terminal or residual values, discount rates and comparable multiples from publicly traded companies in our industry and require us to make certain assumptions and estimates regarding industry economic factors and the future profitability of our business.

When performing an income approach valuation, we incorporate the use of projected financial information and a discount rate that are developed using market participant based assumptions to our discounted cash flow model. Our estimates of discounted cash flow were based upon, among other things, certain assumptions about our expected future operating performance, such as revenue growth rates, operating margins, risk-adjusted discount rates, and future economic and market conditions. The market method of determining the fair value of our reporting units requires us to use judgment in the selection of appropriate market comparables.
