Which of the following must be true for deposits in employee benefit accounts to be compliant?

For deposits in employee benefit accounts to be compliant, it is essential that they align with the plan's investment objectives. This requirement ensures that the investments made are consistent with the overall goals of the employee benefit plan, which may include factors such as risk tolerance, liquidity needs, and the target returns expected for the plan participants. Compliance with the investment objectives reflects a fiduciary responsibility to act in the best interests of the participants and beneficiaries of the plan.

In this context, investment objectives are crucial as they guide the selection of appropriate investment strategies and asset allocations. If deposits do not adhere to these objectives, it could jeopardize the financial security of the employees' benefits and potentially violate regulatory standards regarding proper fund management.

The other options, while they may relate to best practices in investment management, do not address this fundamental compliance criterion. Therefore, ensuring that deposits comply with the plan’s investment objectives is a primary requirement for their compliance.
