[1] | Purchase price and land allocation include $0.9 million related to the acquisition of a land parcel adjacent to an existing site which was subsequently combined with the existing site into a single property upon redevelopment of the existing site. In addition, as part of larger sale-leaseback transactions that included certain of the express tunnel car washes referenced above, we acquired 13 properties that were under construction for $40.0 million and committed to provide additional funding to our tenant during the construction period to complete the development of these assets. These 13 properties did not meet the criteria for sale-leaseback accounting and are accounted for as finance receivables. Accordingly, this initial investment and all subsequent fundings made during the construction period are recorded within notes and mortgages receivable on our consolidated balance sheets, and rental payments resulting from these investments are recorded within interest on notes and mortgages receivable on our consolidated statements of operations. At the end of the construction period, we will recognize the purchase of the assets, remove the finance receivables from our consolidated balance sheets, and begin to record rental income from the operating lease. As of September 30, 2023, we had advanced an additional $4.2 million and, in total, had funded $44.2 million related to these 13 properties.
