2. Income Tax Expense
As part of the process of preparing our consolidated financial statements we are required to determine our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from recognition of items for income tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from taxable income during the carryback period or in the future; and to the extent we believe that recovery is not more likely than not, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must reflect this increase as an expense within the tax provision in the statement of operations. We do not provide for income taxes on undistributed earnings of certain foreign subsidiaries, as our intention is to permanently reinvest these earnings.
We recognize, measure, present and disclose in our financial statements any uncertain tax positions that we have taken, or expect to take on a tax return. We operate in multiple taxing jurisdictions, both within and without the United States, and may be subject to audits from various tax authorities. Management’s judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any valuation allowance recorded against our net deferred tax assets. We will monitor the realizability of our deferred tax assets and adjust the valuation allowance accordingly.
Our policy is to classify interest and penalties related to unrecognized tax benefits as income tax expense. Our 2020 income tax expense varies from the statutory rate mainly due to the generation of federal and state tax credits, permanent items, and different statutory rates from our foreign subsidiaries. Our 2019 income tax expense varied from the statutory rate mainly due to federal and state tax credits, permanent items, different statutory rates from our foreign subsidiaries, and discrete stock option exercises.
We have reviewed the tax positions taken, or to be taken, in our tax returns for all tax years currently open to examination by a taxing authority. As of September 30, 2020, the gross amount of unrecognized tax benefits exclusive of interest and penalties was $803,000. We remain subject to examination until the statute of limitations expires for each respective tax jurisdiction. The statute of limitations will be open with respect to these tax positions until 2027. A reconciliation of beginning and ending amount of our unrecognized tax benefits is as follows:
