“An enhancement deal, conventionally, is when a commercial producer pays money to a nonprofit theater to help subsidize a production. If a theater decides to stage a big musical, for example, a commercial producer may throw in a few hundred thousand dollars — or a couple million in some cases — to raise the show’s production values and get a sense of how it would look in a bigger theater… Some theaters still fear that widespread knowledge of enhancement could jeopardize their reputations, their donations or even their nonprofit status. But as money has become increasingly scarce, the enhancement system has become accepted. In fact it is all but essential, even in Off Broadway’s small and midsize theaters.”
