Cal. Rev. & Tax. Code § 4703.3
Notwithstanding any other provision of law, general, special, or local, if Orange County sells or assigns obligations arising out of delinquent assessments or taxes on the secured roll to a joint powers agency pursuant to Section 26220.5 of the Government Code, the Orange County Board of Supervisors may elect to transfer its tax losses reserve fund to the joint powers agency. The tax losses reserve fund shall be maintained by the joint powers agency according to Section 4703 or 4703.2, whichever is applicable, except that the tax losses reserve fund may both be used to cover losses that may occur in the amount of tax liens as a result of special sales of tax-defaulted property and, subject to agreements with bondholders, be pledged as a reserve for bonds issued by the joint powers agency to purchase the obligations arising out of delinquent assessments or taxes on the secured roll.
