California Code, Insurance Code - INS § 1595

Whenever an admitted alien insurer is required or permitted to deposit assets with a trustee for the benefit and security of its policyholders, or of its policyholders and creditors, in the United States, the trustee of any such trust hereafter created shall be a solvent bank or trust company in the United States acceptable to the commissioner and authorized to act as such trustee by the laws of any State or of the United States. All trusteed assets shall be continuously kept within the United States. Any such trust heretofore created and now existing and any such trust hereafter created and existing when such alien insurer seeks to be admitted, shall be continued in accordance with the terms of the instrument creating it, unless inconsistent with the provisions of this article, in which case said instrument shall, after reasonable notice to and hearing of the alien insurer by the commissioner, be amended to conform to the requirements of this article. No amendment of any deed of trust, whether heretofore or hereafter created, shall be effective unless approved in writing by the commissioner. If the trustees of any such trust heretofore created are natural persons, and if the number of such trustees is reduced, by death, resignation, or from any other cause, to less than three, then the commissioner shall require the substitution for such trustees of a solvent bank or trust company in the United States acceptable to him and authorized to act as such trustee by the laws of any State or of the United States. The commissioner may from time to time approve modifications of, or variations in, any deed of trust, which in his judgment are not prejudicial to the interests of the people of this State.
