40 Pa. Stat. § 183
Upon request of any company, association, or exchange, organized under the laws of this Commonwealth, making the deposit, the Insurance Commissioner may authorize the State Treasurer to return to such company, association, or exchange the whole, or any portion, of the securities held by him on deposit, if the Insurance Commissioner shall be satisfied that the securities so asked to be returned are subject to no liability, and are not required to be longer held by any provision of law, or for the purpose of the original deposit. He may, in like manner, return to the trustees, or other representatives authorized for that purpose, of an insurance company or association of a foreign government, any deposit made by such company, if it shall appear that such company or association has ceased to do business in this Commonwealth, and is under no obligation to policyholders or other persons in this Commonwealth or in the United States, for whose benefit such deposit was made. No deposit, when once made, shall be wholly withdrawn or diminished so long as any liability to policyholders remains unsatisfied, except in case of dissolution by a court or judge of any company, association, or exchange making the deposit, in which case the State Treasurer shall, upon the written order of said court or judge, assign and transfer to the receiver duly appointed all securities or funds in his possession belonging to the company, association, or exchange.
