"Jackson EMC is a not-for-profit cooperative. The board of directors is able to return a portion of the revenue left over after all the bills are paid, funds which we refer to as 'margins', to our members at the end of each year," noted board Chairman Otis Jones. "After this December's refund, Jackson EMC will have returned more than $96 million in margin refunds to its owner/members since the cooperative was founded in 1938."
The action was taken at the EMC's recent annual meeting which also celebrated Jackson EMC's 75th anniversary.
