Contributions
We expect to contribute approximately $10.0 million to our Pension Plans and $8.2 million to our Post-retirement Plans in 2022. As of September 30, 2022, we have contributed $10.0 million and $5.1 million of the annual contribution to the Pension Plans and Post-retirement Plans, respectively.
14. INCOME TAXES
Our unrecognized tax benefits as of September 30, 2022 and December 31, 2021 were $4.9 million. The net amount of unrecognized tax benefits that, if recognized, would result in an impact to the effective tax rate is $4.7 million as of September 30, 2022 and December 31, 2021. We do not expect any material change in our unrecognized tax benefits during the remainder of 2022.
Our practice is to recognize interest and penalties related to income tax matters in interest expense and selling, general and administrative expenses, respectively. As of September 30, 2022, we did not have a material liability for interest or penalties and had no material interest or penalty expense.
The periods subject to examination for our federal return are years 2018 through 2021. The periods subject to examination for our state returns are years 2017 through 2021. In addition, prior tax years may be subject to examination by federal or state taxing authorities if the Company’s net operating loss carryovers from those prior years are utilized in the future. We are currently under examination by certain state taxing authorities. We do not expect any settlement or payment that may result from the examination to have a material effect on our results or cash flows.
Our effective tax rate was 11.9% and (24.2)% for the quarters ended September 30, 2022 and 2021, respectively, and 11.5% and 1.3% for the nine-month periods ended September 30, 2022 and 2021, respectively.
On March 2, 2022, we entered into a definitive agreement to sell substantially all the assets of our Kansas City operations. On September 22, 2021, we entered into a definitive agreement to sell substantially all of the assets of our non-core, rural ILEC business located in Ohio (the “Ohio transaction”). The Ohio transaction closed on January 31, 2022. As a result of the Kansas City and Ohio transactions, we recorded an increase of $1.9 million and $23.2 million to our current tax expense for the quarter and nine months ended September 30, 2022, respectively, related to the writedown of noncash goodwill included in the transactions that is not deductible for tax purposes. For the Ohio transaction, we recorded an increase to our current tax expense of $1.5 million for the quarter and nine-month period ended September 30, 2021 related to the writedown of noncash goodwill in 2021. The Company does not consider these sales transactions and related goodwill adjustments unusual or infrequent and therefore the corresponding tax impact is recorded through continuing operations.
The investment made by Searchlight in 2020 is treated as a contribution of equity for federal tax purposes. Accordingly, the impact of the non-cash PIK interest expense, discount and issuance costs, and fair value adjustments on the CPR are not recognized for federal income tax purposes, resulting in an increase to our current tax expense of $3.6 million and $34.7 million for the quarter and nine months ended September 30, 2021, respectively.
For the quarter and nine months ended September 30, 2021, the Company utilized the discrete effective tax rate method, as allowed by ASC 740-270-30-18, “Income Taxes – Interim Reporting,” to calculate its interim income tax provision. The Company applied the discrete method, at that time, because the application of the estimated annual effective tax rate method (i) was not reliable due to the high degree of uncertainty in estimating annual pretax earnings and (ii) would result in small changes to the projected ordinary annual income causing significant changes in the estimated annual effective rate.
Exclusive of the discrete effective tax rate method and permanent income tax impact related to the Kansas City, Ohio, and Searchlight transactions, our effective tax rate for the quarters ended September 30, 2022 and 2021 would have been approximately 28.2% and 23.9%, respectively, and approximately 26.1% and 25.6% for the nine months ended September 30, 2022 and 2021, respectively. The effective tax rate differed from the federal and state statutory rates primarily due to permanent income tax differences related to the Kansas City, Ohio, and Searchlight transactions, recurring permanent tax differences, and differences in allocable income for the Company’s state tax filings.
