On December 17, 2018, as approved by the independent conflicts committee of the Board, we entered into an Asset Exchange Agreement (the “Asset Exchange Agreement”) with Circle K. Pursuant to the Asset Exchange Agreement, the parties agreed to exchange (i) certain assets of CrossAmerica related to 56 convenience and fuel retail stores previously leased and operated by Circle K pursuant to a master lease that CrossAmerica previously purchased jointly with or from CST (the “master lease properties”), and 17 convenience and fuel retail stores previously owned and operated by CrossAmerica located in the U.S. Upper Midwest (collectively, including the master lease properties, the “CAPL Properties”), having an aggregate fair value of approximately $184.5 million, for (ii) certain assets of Circle K related to 192 (162 fee and 30 leased) company-operated convenience and fuel retail stores (the “CK Properties”), having an aggregate fair value of approximately $184.5 million. The existing fuel supply arrangements for the 56 master lease properties remained unchanged.

The assets exchanged by CrossAmerica included (i) its fee simple title to all land and other real property and related improvements owned by CrossAmerica at the CAPL Properties, (ii) all buildings and other improvements located on the CAPL Properties, (iii) all tangible personal property owned by CrossAmerica and primarily used in connection with the operation of the CAPL Properties, including all underground storage tanks located on such properties and owned by CrossAmerica, (iv) CrossAmerica’s rights under certain contracts related to the CAPL Properties, (v) all in-store cash, inventory owned by CrossAmerica and assignable permits owned or held by CrossAmerica at the 17 convenience store sites owned and operated by CrossAmerica, (vi) all real estate records and related registrations and reports relating exclusively to the CAPL Properties, and (vii) all goodwill and other intangible assets associated with the foregoing assets (collectively, the “CAPL Assets”). The assets exchanged by Circle K included (a) its fee simple title to all land and other real property and related improvements owned by Circle K at the CK Properties, (b) all buildings and other improvements located on the CK Properties, (c) all tangible personal property owned by Circle K and primarily used in connection with the operation of the CK Properties, including all underground storage tanks located on such properties and owned by Circle K, (d) Circle K’s rights under the dealer agreements and agent agreements to be entered into and assigned to CrossAmerica relating to each CK Property that will be dealerized as contemplated by the Asset Exchange Agreement, (e) Circle K’s rights under certain contracts related to the CK Properties, (f) all real estate records and related registrations and reports relating exclusively to the CK Properties, and (g) all goodwill and other intangible assets associated with the foregoing assets (collectively, the “CK Assets”). CrossAmerica will also assume certain liabilities associated with the CK Assets, and Circle K assumed certain liabilities associated with the CAPL Assets.

The CK Properties were assigned to CrossAmerica in multiple tranches after Circle K executed a dealer agreement or agent agreement, as applicable, with respect to each CK Property to be included in a tranche and the applicable dealer or agent assumed possession and operating control of such property. As a result, the exchange of assets pursuant to the Asset Exchange Agreement occurred in a series of separate tranche closings as Circle K entered into such dealer agreements or agent agreements. At each separate closing, CK Properties and related CK Assets were exchanged for CAPL Properties and related CAPL Assets of approximately equivalent value.

Each separate closing was subject to the satisfaction or waiver of customary closing conditions. The Asset Exchange Agreement contains customary representations, warranties, agreements and obligations of the parties. CrossAmerica and Circle K have generally agreed to indemnify each other for breaches of the representations, warranties and covenants contained in the Asset Exchange Agreement for a period of 18 months after the date of the final closing (or for certain specified losses, until the expiration of the applicable statute of limitations). Except for such specified losses, the respective indemnification obligations of each of CrossAmerica and Circle K to the other will not apply to the first $1.845 million of losses and the aggregate indemnification obligations will not exceed $39.9 million.

In connection with the execution of the Asset Exchange Agreement, CrossAmerica and Circle K also entered into an Environmental Responsibility Agreement (the “ERA”), which agreement sets forth the parties’ respective liabilities and obligations with respect to environmental matters relating to the CAPL Properties and the CK Properties. Generally, (i) each party retained liability for known contamination at the sites it transferred to the other party and (ii) each party assumed liability for unknown contamination at the sites it received from the other party, except that the ERA does not affect any liability that Circle K currently has under the existing master lease of the master lease properties.

In the first asset exchange, which closed on May 21, 2019, Circle K transferred to the Partnership 60 (52 fee; 8 leased) U.S. company operated convenience and fuel retail stores (“CK Properties”) having an aggregate fair value of approximately $58.1 million, and the Partnership transferred to Circle K all 17 of the Upper Midwest properties and the real property for eight of the master lease properties (“CAPL Properties”) having an aggregate fair value of approximately $58.3 million.

In the second asset exchange, which closed on September 5, 2019, Circle K transferred to the Partnership 56 (51 fee; 5 leased) CK Properties having an aggregate fair value of approximately $50.2 million, and the Partnership transferred to Circle K the real property for 19 CAPL Properties having an aggregate fair value of approximately $51.4 million.

In the third asset exchange, which closed on February 25, 2020, Circle K transferred to the Partnership ten (all fee) CK Properties having an aggregate fair value of approximately $11.0 million, and the Partnership transferred to Circle K the real property for five CAPL Properties having an aggregate fair value of approximately $10.3 million.

In the fourth asset exchange, which closed April 7, 2020. Circle K transferred to the Partnership 13 (11 fee: 2 leased) CK Properties having an aggregate fair value of approximately $13.1 million, and the Partnership transferred to Circle K the real property for seven CAPL Properties having an aggregate fair value of approximately $12.8 million.

In the fifth asset exchange, which closed May 5, 2020, Circle K transferred to the Partnership 29 (22 fee; 7 leased) CK Properties having an aggregate fair value of approximately $31.5 million, and the Partnership transferred to Circle K the real property for 13 CAPL Properties having an aggregate fair value of approximately $31.7 million.

In the sixth and final asset exchange, which closed September 15, 2020, Circle K transferred to the Partnership 23 (17 fee; 6 leased) CK Properties having an aggregate fair value of approximately $20.4 million, and the Partnership transferred to Circle K the real property for four CAPL Properties having an aggregate fair value of approximately $20.0 million. Because the sixth asset exchange represents the final closing contemplated by the Asset Exchange Agreement, Circle K also transferred a $6.7 million cash payment to the Partnership in connection with the closing, in accordance with the terms of the Asset Exchange Agreement, which included the $0.4 million cumulative deficit in the fair value of the CK Properties we acquired compared with the fair value of the CAPL Properties we divested.

We accounted for the first two tranches of the asset exchanged (that closed in 2019) as transactions between entities under common control as our General Partner was owned by Circle K at the time of the closing of those transactions. As such, the sites divested were recorded as a charge against equity. The sites acquired were recorded at carryover book basis from Circle K’s balance sheet as a contribution to equity.

Since our General Partner was acquired by the Topper Group in November 2019, the Partnership and Circle K were not entities under common control at the time of closing on the third, fourth, fifth and sixth asset exchanges. In connection with these asset exchanges, we recognized gains on the sales of the CAPL Properties, including the proceeds mentioned above, totaling $19.3 million in 2020, representing the fair value of assets and cash consideration received less the carrying value of assets transferred to Circle K. Additionally, we recorded the following to reflect the acquisition of the CK Properties in these asset exchanges (in thousands):
