(a) A licensee shall maintain at all times permissible investments that have a market value computed in accordance with generally accepted accounting principles or international financial reporting standards of not less than the aggregate amount of all of its outstanding payment instruments and stored value and prepaid access obligations issued or sold in all states and money transmitted from all states by the licensee.
(b) The commissioner, with respect to any licensees, may limit the extent to which a type of investment within a class of permissible investments may be considered a permissible investment, except for money and certificates of deposit issued by a bank. The commissioner by rule may prescribe or by order allow other types of investments that the commissioner determines to have a safety substantially equivalent to other permissible investments.
(c) Permissible investments, even if commingled with other assets of the licensee, are held in trust for the benefit of the purchasers and holders of the licensee's outstanding payment instruments and stored value and prepaid access obligations in the event of bankruptcy or receivership of the licensee.
