Conn. Gen. Stat. § 38a-898

If any insurer fails, by reason of insolvency, to pay any assessment, the fund shall cause the reimbursement ratios, computed under subsection (a) of section 38a-896 , to be immediately recalculated, excluding therefrom the amount of the insolvent insurer's assessment determined by the Insurance Commissioner to be uncollectible, so that such uncollectible amount is, in effect, assumed and redistributed among the remaining insurers. In any such event, the remaining insurers shall increase the additional premium charges made under section 38a-897 proportionately such that over the remainder of the three-year period the aggregate of the increases of additional premium charges shall be equal to the uncollectible assessment so assumed and redistributed to the remaining insurers.
