A signatory document is?

• A. A budget approval form
• B. A non-binding memo
• C. A legally binding agreement between a producer and a union or guild committing to abide by the union's collective bargaining agreement.
• D. A film distribution contract

Answer: (C)

The key idea is that a signatory document is the formal instrument by which a producer (or company) agrees to be bound by a union’s collective bargaining agreement. It creates a legal relationship in which the producer commits to the terms negotiated in the CBA—wages, hours, working conditions, benefits, grievance procedures, and other obligations that apply when hiring union members. This makes the producer a “signatory” to the union’s agreement and ensures enforceable compliance with the union’s rules on that work.

That's why the correct option describes a legally binding agreement between a producer and a union or guild committing to abide by the union's collective bargaining agreement. The other options don’t fit because they concern administrative forms, non-binding memos, or contracts unrelated to the union’s binding terms.
