The provision for income taxes differs from the amount computed by applying the Federal statutory income tax rate before the provision for income taxes.

The reconciliation of the Federal statutory income tax rate to the effective income tax rate is as follows:

	Three Months Ended				Nine Months Ended
	September 30, 2022		September 30, 2021		September 30, 2022		September 30, 2021
Federal statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State income taxes, net of Federal benefit	5.0		3.4		4.7		3.0
Excess tax benefits	(1.5)		(2.2)		(1.6)		(6.0)
Return to provision adjustments	(0.4)		0.6		(0.5)		—
Other	(0.8)		(0.3)		(1.7)		(0.4)
Effective tax rate	23.3	%	22.5	%	21.9	%	17.6	%

On May 21, 2021, the State of Oklahoma enacted House Bill 2960, effectively reducing the corporate income tax rate in Oklahoma from 6% to 4%. This resulted in an overall reduction of our effective state income tax rate for the three and nine months ended September 30, 2021, net of Federal benefit.

During the nine months ended September 30, 2022, the Company recorded an excess tax benefit of $1.3 million as compared to $3.8 million during the same period in 2021, a decrease of 67%. The decrease was primarily due to timing of stock option exercises as a result of our high stock price during the nine months ended September 30, 2021.

We earn investment tax credits from the state of Oklahoma’s manufacturing property investment program. We use the flow-through method to account for investment tax credits earned on eligible tangible asset expenditures. Under this method, the investment tax credits are recognized as a reduction to our Oklahoma income tax expense in the year they are used. As of September 30, 2022, we have investment tax credit carryforwards of approximately $4.4 million. These credits have estimated expirations from the year 2038 through 2042.

The Company's estimated annual 2022 effective tax rate, excluding discrete events, is approximately 25%. We file income tax returns in the U.S., state and foreign income tax returns jurisdictions. We are subject to U.S. income tax examinations for tax years 2018 to present, and to non-U.S. income tax examinations for the tax years 2017 to present. In addition, we are subject to state and local income tax examinations for the tax years 2017 to present. The Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be recognized as a component of income tax expense.
