10. POST-RETIREMENT BENEFITS

Effective

January 1, 1992,

we adopted the Outside Directors

’ Retirement Plan which provides that each non-employee director, upon resignation from the Board of Directors after reaching the age of

65,

will receive a cash payment equal to

$5,000

for each full year of service as a director of the Company (and its predecessors and successors) up to

$50,000.

The plan was terminated in

2011.

At

December 31, 2017

and

2016,

we have accrued

$50,000,

which is included in other current liabilities in the Consolidated Balance Sheets, for future payments that were earned under the plan before it was terminated.
