Before approving amendments to the plan language governing its common trust fund, what should the board of directors ensure does not result from this amendment?

When considering amendments to the plan governing a common trust fund, it is essential for the board of directors to ensure that the costs associated with making those amendments are not charged to the fund itself. The primary reason for this is that the fiduciary duty requires the bank to act in the best interests of the fund’s beneficiaries. Charging the costs of amending the plan to the fund could negatively impact the beneficiaries' returns and overall fund performance.

By ensuring that these costs are absorbed by the bank instead, the board protects the integrity and financial interests of the fund. This action not only aligns with fiduciary standards but also promotes transparency and fairness in the management of the trust fund.

The other options do not address the direct concerns related to fiduciary responsibilities regarding the costs incurred from amending the plan. While they may touch on other important considerations, they do not focus on the critical issue of ensuring that beneficiaries are not unfairly burdened with the costs of the amendments.
