10 — Income Taxes
For the three and nine months ended September 30, 2023, we recorded a provision for income tax expense of $1,341,352 and $3,403,523, respectively. Our effective tax rate was 20.9 percent and 21.2 percent, respectively, and differed from the U.S. Federal statutory rate primarily due to U.S. state income tax expense, partially offset by benefits from research and development tax credits.
For the three and nine months ended September 30, 2022, we recorded a provision for income tax expense of $810,375 and $2,322,301 respectively. Our effective tax rate was 19.1 percent and 20.2 percent respectively and differed from the U.S. Federal statutory rate primarily due to U.S. Federal income tax expense, partially offset by benefits from foreign derived intangible income and research and development tax credits.
As of September 30, 2023 and December 31, 2022, we had not identified or accrued for any uncertain tax positions. We are currently unaware of any uncertain tax positions that could result in significant payments, accruals, or other material deviations in this estimate over the next 12 months. We believe that our tax positions comply in all material respects with applicable tax law. However, tax law is subject to interpretation, and interpretations by taxing authorities could be different from ours, which could result in the imposition of additional taxes and penalties.
We file tax returns in the United States Federal jurisdiction and many U.S. state jurisdictions. Our returns are not currently under examination by the Internal Revenue Service. The Company remains subject to income tax examinations for our United States Federal and certain U.S. state income taxes for 2019 and subsequent years.
11 — Leases
We have entered into operating lease contracts for our manufacturing plant, office space, and various office equipment with one material lease contract outstanding.
In January 2014, we entered into a non-cancelable operating lease, commencing July 1, 2014, for our manufacturing and headquarters facility in Winter Springs, Florida owned by Susi, LLC, an entity controlled by our President, Chief Executive Officer, and Chairman of the Board, Roger Susi. Pursuant to the terms of our lease for this property, the monthly base rent is $34,133, adjusted annually for changes in the consumer price index. The Company paid Susi, LLC $127,817 for the three months ended September 30, 2023 and 2022. For the nine months ended September 30, 2023 and 2022, the Company paid Susi, LLC $386,958 and $364,825 respectively. For the year ended December 31, 2022, the Company paid Susi, LLC $492,643 related to this lease. Under the terms of the lease, we are responsible for insurance and maintenance expenses. Prior to May 31, 2019, the expiration date of the initial lease term, and pursuant to the terms of the lease contract, we renewed the lease for an additional five years, resulting in a new lease expiration date of May 31, 2024. Unless advance written notice of termination is timely provided, the lease will automatically renew for one additional successive term of five years beginning in 2024, and thereafter, will be renewed for successive terms of one year each. At the time we adopted ASU 2016-02, Leases (Topic 842), we concluded that we would exercise the remaining five-year option, resulting in a remaining lease term of 6.5 years as of September 30, 2023. This lease agreement does not contain any residual value guarantee or material restrictive covenants.
In February 2023, we entered into two, two-year, non-cancelable operating leases with non-related parties for additional office space in Winter Springs, Florida. Pursuant to the lease terms the total monthly base rent is $10,055. For the three months ended September 30, 2023 and 2022, the Company paid $30,165 and $0 respectively. For the nine months ended September 30, 2023 and 2022, the Company paid $83,140 and $0 respectively. Under the terms of the leases, we are responsible for insurance and maintenance expenses. Pursuant to the contract terms, the leases will expire February 2025 and do not contain any residual value guarantee or material restrictive covenants.
We will reassess the lease accounting terms and assumptions once the details regarding completion of a new manufacturing facility and planned departure of the current primary facility is finalized.
