Gov. Code, § 6509.7

(a) Notwithstanding any other provision of law, two or more public agencies that have the authority to invest funds in their treasuries may, by agreement, jointly exercise that common power. Funds invested pursuant to an agreement entered into under this section may be invested in securities and obligations as described by subdivision (p) of Section 53601. A joint powers authority formed pursuant to this section may issue shares of beneficial interest to participating public agencies. Each share shall represent an equal proportionate interest in the underlying pool of securities owned by the joint powers authority. To be eligible under this section, the joint powers authority issuing the shares of beneficial interest shall have retained an investment adviser that meets all of the following criteria:

(1) The adviser is registered or exempt from registration with the Securities and Exchange Commission.

(2) The adviser has not less than five years of experience investing in the securities and obligations authorized in subdivisions (a) to (o), inclusive, of Section 53601.

(3) The adviser has assets under management in excess of five hundred million dollars ($500,000,000).

(b) As used in this section, “public agency” includes a nonprofit corporation whose membership is confined to public agencies or public officials, in addition to those agencies listed in Section 6500.

(c) A joint powers authority formed pursuant to this section is authorized to establish the terms and conditions pursuant to which agencies may participate and invest in pool shares. Consistent with its status as a public agency as provided under Section 6500, a federally recognized Indian tribe is eligible to participate in a joint powers authority formed under this section or otherwise invest in pool shares consistent with the terms and conditions established by the joint powers authority.
