|Income Tax Disclosure [Abstract]
We are subject to U.S. federal, state and international income taxes. We are generally no longer subject to federal, state, or international income tax examinations by tax authorities for years before 2019 with a few exceptions. Due to the potential for resolution of state and foreign examinations, and the expiration of various statutes of limitations, it is reasonably possible that our gross unrecognized tax benefit balance may change within the next twelve months by a range of $0 to $8.4 million.
Effective Tax Rate
Our effective income tax rate was 13.9% for the three months ended September 30, 2023, compared to 24.0% for the three months ended September 30, 2022. Our effective income tax rate was 22.0% for the nine months ended September 30, 2023, compared to 25.0% for the nine months ended September 30, 2022. Our effective tax rate was lower for the third quarter and the first nine months of 2023 as compared to the same periods in 2022 due to the write off of a deferred tax liability related to our original investment in BVS which was no longer necessary given the acquisition of the company in the third quarter of 2023, partially offset by the tax impact of the penalty associated with resolution of the investigation of the 2017 cybersecurity incident by the U.K. FCA which is not tax deductible.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
