Senate Bill 1370 provides for conditions under which a supplier may terminate a distributor relationship in the absence of good cause with sixty days’ notice and provided that “irrevocable loss” (defined as the loss of volume of such brand or brands accounting for more than ten per centum of the entire liquid volume of malt or brewed beverages or gross sales amount distributed by the importing distributor in the twelve months preceding the written notice, whichever is less) to the distributor does not result from the termination.
