However, losses in certain jurisdictions and discrete items are treated separately. The gain on the Kingstone transaction, described in Note 10, was treated as a discrete item and accounted for $1.7 million of the tax expense in the quarter, with the tax calculated utilizing the effective tax rate and other discrete items nearly offsetting each other. 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. 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, 2016 the valuation allowance increased by a net of $1.1 million primarily due to net operating losses in The Netherlands, France and China, partially offset by a decrease in the valuation allowance due to utilization of net operating losses in the United States. The Company classifies all of our uncertain tax positions as non-current income taxes payable. At March 31, 2016 and September 30, 2015, the total amount of unrecognized tax benefits was approximately $2.4 million and $1.8 million, respectively. If recognized, these amounts would favorably impact the effective tax rate. Income taxes payable long-term primarily includes, among other items, withholding taxes that are not due until the related intercompany service fees are paid. The Company classifies interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2016 and September 30, 2015, the Company had an accrual for potential interest and penalties of approximately $2.0 million and $1.8 million, respectively, classified with non-current income taxes payable.
