Cal. Ins. Code § 12372.5
Notwithstanding the provisions of Section 12372, where a title plant is not being currently maintained, the asset value of such plant shall not exceed its asset value as of the last annual statement date preceding the first month such plant is not currently maintained, less 1/10th thereof for each succeeding year or part thereof that such plant is not being currently maintained. For the purposes of this section, a title plant shall be deemed currently maintained so long as it is used in the normal conduct of the business of title insurance, and (1) the owner thereof continues regularly to obtain and index title record data to such plant or to a continuation thereof in a format other than that previously used, including, but not limited to, computerization of such data, or (2) the owner thereof is a participant, in an arrangement for joint use of a title plant system regularly maintained in any format, provided such owner is contractually entitled to receive a copy of the title record data contained in such jointly used title plant system during the period of such owner's participation therein, either periodically or upon termination of such participation, at a cost not to exceed the actual cost of duplication of such title record data.
