We enter into lease agreements for certain retail stores, warehouses, distribution centers, office space and land as well as service contracts that are considered leases.

Our leases have remaining lease terms, including renewals reasonably certain to be exercised, of less than one year to approximately 38 years. Most of our leases include one or more options to extend the lease, for periods ranging from one year to 30 years or more.

Historical failed sale leasebacks that were assumed through acquisitions and do not qualify for sale leaseback accounting continue to be accounted for as financing obligations. As of March 28, 2020, net assets of $4.5 million and liabilities of $7.5 million due to failed sale leaseback arrangements were included with finance lease assets and liabilities, respectively, on the Consolidated Balance Sheet.
