According to Mr. Gabelli's employment contract with Gamco, he is required to spend "the substantial majority of his working time" operating that business. Mr. Gabelli's generous compensation poses a particular problem for Mr. Mancheski and Mr. Perlmutter. Both contend that as minority shareholders in G.G.C.P., they can only watch helplessly as Mr. Gabelli has paid himself handsomely with what they say is at least partly their money. While Mr. Mancheski accepts that he had agreed to Mr. Gabelli's initial pay formula, he questions its suitability for the leader of a company that has grown so large. "If I had been advised in 1977 that Mr. Gabelli would pay himself 40 percent of gross revenues generated by him and 20 percent of the company's pretax revenue regardless of how successful the company became, how many additional executives and employees were hired, or how much money that formula produced in any one year, I would not have invested," Mr. Mancheski said in an affidavit.
