This accrual consisted of (a) $11.4 million, which was our estimate of reasonably estimable environmental remediation liability, including obligations to remove USTs for which we are responsible, net of estimated recoveries and (b) $36.2 million for future environmental liabilities related to preexisting unknown contamination. 43 Environmental liabilities are accreted for the change in present value due to the passage of time and, accordingly, $1.3 million, $1.7 million and $1.8 million of net accretion expense was recorded for the years ended December 31, 2022, 2021 and 2020, respectively, which is included in environmental expenses.
Environmental liabilities are accreted for the change in present value due to the passage of time and, accordingly, $0.6 million, $1.3 million and $1.7 million of net accretion expense was recorded for the years ended December 31, 2023, 2022 and 2021, respectively, which is included in environmental expenses.
We believe that the redeveloped properties can be leased or sold at higher values than their current use. During the years ended December 31, 2022 and 2021, rent commenced on two and five completed redevelopment projects, respectively, that were placed back into service in our net lease portfolio.
We believe that the redeveloped properties can be leased or sold at higher values than their prior use. During the year ended December 31, 2023, rent commenced on three completed redevelopments and increased rent commenced on two revenue-enhancing capex projects for expanded convenience stores. During the year ended December 31, 2022, new rent commenced on two completed redevelopment projects.
Accordingly, we removed $23.5 million of unknown reserve liabilities which had previously been accrued for these properties. This resulted in a net credit of $22.2 million being recorded to environmental expense for the year ended December 31, 2022. In addition, during the year ended December 31, 2022, there was a decrease in environmental litigation accruals of $1.6 million.

We believe that conforming to this market practice for calculating AFFO improves the comparability of this measure of performance to other net lease REITs. FFO and AFFO are generally considered by analysts and investors to be appropriate supplemental non-GAAP measures of the performance of REITs.
In addition to measurements defined by GAAP, we also focus on Funds From Operations (“FFO”) and Adjusted Funds From Operations (“AFFO”) to measure our performance. FFO and AFFO are generally considered by analysts and investors to be appropriate supplemental non-GAAP measures of the performance of REITs.
Impairment Charges Impairment charges are recorded when the carrying value of a property is reduced to fair value.
The increase in property costs was primarily due to an increase in reimbursable real estate taxes, partially offset by lower rent expense and non-reimbursable real estate taxes. Impairment Charges Impairment charges are recorded when the carrying value of a property is reduced to fair value.
