C.R.S. § 15-1.1-107
OFFICIAL COMMENT
Wasting beneficiaries' money is imprudent. In devising and implementing strategies for the investment and management of trust assets, trustees are obliged to minimize costs.
The language of Section 7 derives from Restatement of Trusts 2d § 188 (1959). The Restatement of Trusts 3d says: "Concerns over compensation and other charges are not an obstacle to a reasonable course of action using mutual funds and other pooling arrangements, but they do require special attention by a trustee. . . . [I]t is important for trustees to make careful cost comparisons, particularly among similar products of a specific type being considered for a trust portfolio." Restatement of Trusts 3d: Prudent Investor Rule § 227, comment m, at 58 (1992).
