(b)

The board of retirement and, if applicable, the board of investments, may, with the agreement of the county or district, act as one or more of the following for that employer-established trust: trustee, third-party administrator, or investment manager. The board of retirement and, if applicable, the board of investments, may enter a trust agreement, third-party administrative services agreement, investment manager agreement, or other appropriate agreement with the county or district, which shall establish the respective roles and responsibilities of the parties with respect to the administration and investment of the employer-established trust. That agreement shall provide for the manner and method of payment for the reasonable costs related to investment expenses for, and administration of, the employer-established trust. Those expenses shall not be deemed to be an investment or administrative expense of a retirement system under this chapter.

Contributions to the employer-established trust may include the proceeds of debt issued by the county or district solely for the purpose of funding post-employment health, life, or other welfare benefits.
