Income Taxes	Income Taxes The quarterly income tax provision is calculated using an estimated annual effective tax rate, based upon expected annual income, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which the Company operates. However, losses in certain jurisdictions and discrete items are treated separately. Deferred tax assets and liabilities reflect the tax effects of temporary differences between the carrying value of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company records a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Our expectations regarding realization of our deferred tax assets is based upon the weight of all available evidence, including such factors as our recent earnings history, expected future taxable income and available tax planning strategies. As a result of the merger with BTU, the Company determined that is more likely than not that some of our U.S. federal deferred tax assets would not be realized, and recorded a partial valuation allowance in the U.S. The Company maintains a valuation allowance with respect to certain state, federal and foreign deferred tax assets that may not be recovered. Each quarter, the valuation allowance is re-evaluated. During the six months ended March 31, 2015 the valuation allowance increased by $1.5 million due to net operating losses in The Netherlands and United Kingdom, partially offset by utilization of net operating losses in China and France. The Company classifies all of our uncertain tax positions as non-current income taxes payable. At March 31, 2015 and September 30, 2014, the total amount of unrecognized tax benefits was approximately $3.2 million. If recognized, these amounts would favorably impact the effective tax rate. The Company classifies interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2015 and September 30, 2014, the Company had an accrual for potential interest and penalties of approximately $1.8 million and $1.6 million, respectively. The Company and one or more of its subsidiaries file income tax returns in The Netherlands, Germany, France, Singapore, Malaysia, China and Hong Kong, as well as the U.S. and various states in the U.S. The Company and its subsidiaries have a number of open tax years dictated by statute in each of the respective taxing jurisdictions, but generally is from 3 to 5 years.
