15. INCOME TAXES

The Company’s effective tax rate for the nine months ended September 30, 2021 was 25% and was comparable to the effective tax rate for the nine months ended September 30, 2020 of 24.9%. Income tax expense for the nine months ended September 30, 2021 and September 30, 2020 was $61.2 million and $43.9 million, respectively.

During the nine months ended September 30, 2021 and September 30, 2020, the Company realized $2.1 million and $1.4 million, respectively, of excess tax benefits from stock-based awards and recorded a corresponding benefit to income tax expense.

The Company analyzes its deferred tax assets each reporting period, considering all available positive and negative evidence in determining the expected realization of those deferred tax assets. As of September 30, 2021, the Company maintains a valuation allowance of $2.8 million against deferred tax assets primarily related to state tax credits it estimates will expire before they are realized.

The Company operates in multiple tax jurisdictions and, in the normal course of business, its tax returns are subject to examination by various taxing authorities. Such examinations may result in future assessments by these taxing authorities, and the Company accrues a liability when it believes that it is more likely than not that benefits of tax positions will not be realized. As of September 30, 2021, for certain tax jurisdictions tax years 2017 through 2020 remain subject to examination. The Company believes that adequate provisions have been made for all tax returns subject to examination. Sales made to foreign distributors are not taxable in any foreign jurisdiction as the Company does not have a taxable presence in any foreign jurisdiction.
