The commissioner shall make, or cause to be made by the insurance authority of the State where the insurer is organized, an examination of the books and records of the insurer. If, upon such examination, he finds that the insurer has no outstanding liabilities to residents of this State and no policies in favor of the residents of this State uncanceled or the primary liabilities under which have not been reinsured and assumed by another admitted insurer, as required by Section 1071.5, he shall cancel the insurer's certificates of authority, if unexpired, and he shall permit the insurer to withdraw. The commissioner may, in his discretion, waive any or all of the above requirements if, after such examination, he finds it to be in a solvent condition. The cost and expense of all such examinations shall be paid as prescribed in Section 736.
