Revision of Prior Period Financial Statements

In the third quarter of fiscal 2012, the Company identified prior period errors related to the accounting for its equity method investment in ULVAC Cryogenics, Inc. (“UCI”). Specifically, the Company determined that certain subsidiaries of UCI were not fully included in the results of UCI reported to the Company. Therefore the Company’s portion of these subsidiaries of the joint venture were not reflected within equity in earnings of joint ventures in the Company’s consolidated statements of operations or within equity investment in joint ventures in the Company’s consolidated balance sheets for the quarterly and annual periods beginning in the fiscal year ended September 30, 2006 through the quarterly period ended March 31, 2012. In evaluating whether the Company’s previously issued consolidated financial statements were materially misstated, the Company considered the guidance in Accounting Standard Codification (ASC) Topic 250, “Accounting Changes and Error Corrections,” ASC Topic 250-10-S99-1, “Assessing Materiality,” and ASC Topic 250-10-S99-2, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.”

The Company concluded these errors were not material individually or in the aggregate to any of the prior reporting periods, and therefore, amendments of previously filed reports were not required. The Company evaluated the cumulative error in relation to the results for the year ended September 30, 2012 and concluded revision of prior periods was appropriate. As such, the revisions for these corrections to the applicable prior periods are reflected in the financial information herein and will be reflected in future filings containing such financial information. The revision had no net impact on the Company’s consolidated statements of cash flows for any prior period.

The following table summarizes the effects of the error on the annual prior period financial statements (in thousands, except per share data):
