A variable quota share treaty applies different cession percentages to different sub-classes, sub-portfolios or risk bands within the same overall reinsurance treaty. It allows the cedant to optimise its net retention across heterogeneous portfolios while retaining the simplicity of a single treaty placement.

In a variable quota share treaty, the cession percentage varies according to specified parameters defined in the slip. Typical variation parameters include: sub-class of business (a UK motor treaty might cede 40 per cent of private car and 25 per cent of fleet); risk size band (50 per cent of policies under £5,000 premium and 30 per cent above); jurisdiction; or risk attribute (e.g. 40 per cent of new business and 25 per cent of renewals).
The structure allows the cedant to manage net retention more precisely by reference to the relative attractiveness of each sub-class, while avoiding the placement complexity of multiple separate treaties.
The variable quota share is documented in the Market Reform Contract with a cession matrix or schedule specifying the applicable percentage for each sub-class. The underlying legal framework is identical to that of a standard quota share.
In practice the cedant’s cession bordereau identifies the sub-class of each policy and applies the corresponding cession rate. The cedant must therefore maintain robust systems to identify and segment the underlying business correctly. Errors in classification can produce disputes about the appropriate cession rate.
Variable quota share treaties are valuable for cedants with heterogeneous portfolios where a single cession rate would be too high for some segments and too low for others. They allow the cedant to retain more of profitable segments and cede more of segments where the reinsurer’s pricing is more competitive.
An illustrative example: a UK SME insurer writes commercial property, BI and liability under a single composite treaty. The variable quota share cedes 25 per cent of property, 30 per cent of BI and 50 per cent of liability, reflecting the cedant’s different retention appetite by class. The overall blended cession rate, weighted by premium, is 32 per cent.
