Long-Lived Assets	Long-Lived Assets: Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the assets may not be recoverable. In order to determine if an asset has been impaired, assets are grouped and tested at the lowest level for which identifiable, independent cash flows are available. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decrease in the market price of a long-lived asset; a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition; a significant adverse change in legal factors or in the business climate; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset; past, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset; and a current expectation that a long-lived asset will be sold or disposed significantly before the end of its previously estimated useful life. Any adverse change in these factors could have a significant impact on the recoverability of these assets and could have a material impact on the unaudited condensed consolidated financial statements. We concluded no indicators of impairment existed during the first three months of 2023 and 2022, respectively. We based our conclusions on our financial performance projections, as well as an updated analysis of macroeconomic and industry-specific conditions. On June 27, 2022, the Partnership sold the land at California's Great America for a cash purchase price of $310 million, subject to customary prorations, which resulted in a $155.3 million gain recorded, net of transaction costs, within "Gain on sale of assets" in the unaudited condensed consolidated statement of operations and comprehensive income during the third quarter of 2022. Concurrently with the sale, we entered into a lease contract that allows us to operate the park during a six-year term, see below. As a result, we changed the estimated useful lives of the remaining property and equipment at California's Great America to an approximate 5.5-year period, or through December 31, 2027. We expect this to result in an approximate $8 million increase in annual depreciation expense over the 5.5-year period. We may dispose of the remaining property and equipment at California's Great America significantly before the end of their previously estimated useful lives if the assets are not sold to a third party or transferred for an alternate use. As a result, we tested the long-lived assets at California's Great America for impairment during the second quarter of 2022, which resulted in no impairment. The fair value of the long-lived assets was determined using a replacement cost approach. Under the lease contract entered into in connection with selling the land at California's Great America, we can continue to operate the park during a six-year term, and we have an option to extend the term for an additional five years. The lease is subject to early termination by the buyer with at least two years' prior notice. Upon termination of the lease, we will close existing park operations and remove the rides and attractions from the land. The annual base rent under the lease initially was $12.2 million and will increase by 2.5% per year. Upon commencement of the lease, we recognized a right-of-use asset and lease liability equal to the annual base rent for the initial six-year term and estimated lease payments totaling $12.8 million to dismantle and remove rides and attractions upon termination of the lease. The discount rate used to determine the present value of the future lease payments was our incremental borrowing rate.
