Sec. 13. POLICYHOLDER ASSESSMENT. (a) Each policyholder of the association has a contingent liability for a proportionate share of any assessment of policyholders made under this article.
(b) If a deficit as calculated under the plan of operation is sustained by the association in any year, the board of directors shall levy an assessment only on those policyholders who had policies in force at any time during the two most recently completed calendar years in which the association issued policies preceding the date on which the assessment is levied.
(c) The aggregate amount of the assessment shall be equal to that part of the deficit that is not paid from the policyholder stabilization reserve fund.
(d) The maximum aggregate assessment for each policyholder may not exceed the annual premium for the liability policy from the association most recently in effect.
(e) Subject to the limitation provided by Subsection (d) of this section, each policyholder shall be assessed for that portion of the deficit that reflects the proportion that the earned premium on the policies of the policyholder bears to the total earned premium for all policies of the association in the two most recently completed calendar years.
