Employee Benefit Plans	The Company adopted the Schmitt Industries, Inc. 401(k) Profit Sharing Plan & Trust effective June 1, 1996. Employees must meet certain age and service requirements to be eligible. Participants may contribute up to 15% of their eligible compensation which may be partially matched by the Company. The Company may make further contributions in the form of a profit-sharing contribution or a discretionary contribution. The Company made matching contributions in conjunction with employee contributions to the plan totaling $5,710 and $40,336 during the years ended May 31, 2020 and 2019, respectively.

The entire disclosure for postemployment benefits, which may include supplemental unemployment benefits, obligations recognized for all types of benefits provided to former or inactive employees, their beneficiaries, and covered dependents after employment but before retirement. Disclosure may also include discussion that an obligation for postemployment benefits is not accrued in accordance with regulation only because the amount cannot be reasonably estimated.
