Final answer:
There has been a significant change in management contracts due to increased competition among operators and the more active role of owners in managing their investments.
Step-by-step explanation:
The statement 'There has been a significant change in management contracts due to increased competition among operators and the more active role of owners in managing their investments.' is True.
The increased competition among operators and the more active role of owners in managing their investments have indeed led to significant changes in management contracts. With more competition, operators have had to revise their contracts to stay relevant and competitive. Additionally, owners taking a more active role in managing their investments means they have a greater say in how the contracts are structured and managed.
