Sale Leaseback Transaction, Lease Terms	The leases for the Columbus, OH and Montgomery, AL distribution centers each have an initial term of 15 years and multiple five-year extension options. The leases for the Durant, OK and Tremont, PA distribution centers each have an initial term of 20 years and multiple five-year extension options. At lease commencement, we determined that none of the extension options were reasonably certain to be exercised. Therefore, none of the extension options were included in the computation of the operating lease liabilities and operating lease right-of-use assets. At commencement of the leases, we recorded aggregate operating lease liabilities of $466.1 million and aggregate operating lease right-of-use assets of $466.1 million. The weighted average discount rate for the leases was 6.2%. All of the leases are absolute net. Additionally, all of the leases include a right of first refusal beginning after the fifth year of the initial term which allows us to purchase the leased property if the buyer-lessor receives a bona fide purchase offer from a third-party. In connection with our entrance into the sale and leaseback transactions, we agreed to repay all borrowings outstanding under the 2018 Credit Agreement and restrict our borrowings under the 2018 Credit Agreement for 90 days following closing of the transactions.
