Commitments and Contingencies

Leases. We have various operating leases for buildings and land on which some of our operations are located as well as trucks utilized for deliveries in certain branches. Future minimum lease payments due under operating leases with an initial term of one year or more at April 1, 2018 are as follows:



(In thousands)	2019		2020		2021		2022		2023		Thereafter
Minimum lease payment	$	2,699	$	2,493	$	2,058	$	1,127	$	564	$	2,434

Total rental expense for fiscal years 2018, 2017 and 2016 was as follows:



	2018		2017		2016
(In thousands)
Minimum rentals	$	2,959	$	3,283	$	2,890
Contingent rentals	26		28		21
Total rental expense	$	2,985	$	3,311	$	2,911

Litigation. As of April 1, 2018, there were no material pending legal proceedings, other than ordinary routine litigation incidental to the business, to which we or any of our subsidiaries are a party or of which any of our property is the subject. Legal fees associated with such matters are expensed as incurred.

Environmental Remediation: During fiscal 2018, we recorded a liability of $0.6 million related to estimated remediation expenses associated with existing trichloroethylene contamination at our Minneapolis facility. The liability is not discounted as management expects to incur these expenses during fiscal 2019. Given the many uncertainties involved in assessing environmental claims, our reserves may prove to be insufficient. While it is possible that additional expenses related to remediation will be incurred in future periods if currently unknown issues arise, we are unable to estimate the extent of any further financial impact.

Asset Retirement Obligations. We have three leases of land which contain terms that state that at the end of the lease term, we have a specified amount of time to remove the property and buildings. These leases expire in 2023, 2028 and 2034. At that time, anything that remains on the land becomes the property of the lessor, and the lessor has the option to either maintain the property or remove the property at our expense. We have not been able to reasonably estimate the fair value of the asset retirement obligations, primarily due to the combination of the following factors: The leases do not expire in the near future; we have a history of extending the leases with the lessors and currently intend to do so at expiration of the lease periods; the lessors do not have a history of terminating leases with their tenants; and because it is more likely than not that the buildings will have value at the end of the lease life and therefore, may not be removed by either the lessee or the lessor. Therefore, in accordance with accounting guidance related to asset retirement and environmental obligations, we have not recorded an asset retirement obligation as of April 1, 2018. We will continue to monitor the factors surrounding the requirement to record an asset retirement obligation and will recognize the fair value of a liability in the period in which it is incurred and a reasonable estimate can be made.
