Goodwill is subject to our annual impairment test during the fourth quarter of our fiscal year, or earlier if indicators of potential impairment exist, using a fair value-based approach. We completed our most recent annual impairment test during the fourth quarter of fiscal year 2012 and concluded that there was no impairment. For the purposes of completing our most recent impairment test, we perform either a qualitative or a quantitative analysis on a reporting unit basis.

In a qualitative analysis, we evaluate factors including, but not limited to, macro economic conditions, market and industry conditions, competitive environment, operational stability and the overall financial performance of the reporting units including cost factors and budgeted-to-actual revenue results. In a quantitative analysis, we use estimates of future revenues, costs and cash flows from such units. This assessment is based upon a discounted cash flow analysis and analysis of our market capitalization. The estimate of cash flow is based upon, among other things, certain assumptions about expected future operating performance such as revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions, and determination of appropriate market comparables.

The amount of goodwill allocated to our GPU business, PSB, and CPB segments as of January 29, 2012 was $133.1 million, $95.1 million and $412.8 million, respectively, and as of January 30, 2011 was $133.1 million, $95.1 million and $141.6 million, respectively. Please refer to Note 18 of these Notes to the Consolidated Financial Statements for further discussion regarding segments.
