16 Pa. Stat. § 5509-A
All moneys of any Authority, from whatever source derived, shall be paid to the treasurer of the Authority. Said moneys shall be deposited in the first instance by the treasurer in one or more banks or trust companies, in one or more special accounts, and each of such special accounts, to the extent the same is not insured, shall be continuously secured by a pledge of direct obligations of the United States of America, of the Commonwealth or of the county or city creating the Authority, having an aggregate market value, exclusive of accrued interest, at all times at least equal to the balance on deposit in such account. Such securities shall either be deposited with the treasurer or be held by a trustee or agent satisfactory to the Authority. All banks and trust companies are authorized to give such security for such deposits. The moneys in said accounts shall be paid out on the warrant or other order of the chairman of the Authority or of such other person or persons as the Authority may authorize to execute such warrants or orders. Every Authority shall have at least an annual examination of its books, accounts and records by a certified public accountant. A copy of such audit shall be delivered to the county or city creating the Authority. A concise financial statement shall be published annually at least once in a newspaper of general circulation in the county or city where the principal office of the Authority is located. If such publication is not made by the Authority, the county or city shall publish such statement at the expense of the Authority. If the Authority fails to make such an audit, then the controller, auditors or accountant designated by the county or city is hereby authorized and empowered from time to time to examine, at the expense of the Authority, the accounts and books of the Authority, including its receipts, disbursements, contracts, leases, sinking funds, investments and any other matters relating to its finances, operation and affairs. The Attorney General shall have the right to examine the books, accounts and records of any Authority.
