Structure of cover is also very relevant to stability. Bundling of flood with other perils facilitates economies of scale and
lowers the ratio of maximum loss to premium income, thereby reducing demands on capital reserves. Single peril schemes
may exhibit correlated losses and induce insolvency. Bundling can also contribute to affordability and availability as
climate change may not have such a large impact on the totality of hazard cover as it does on flood risk. Add-on or single
peril schemes, by making subsidies transparent, are more likely to be actuarially priced and less affordable for those at
most risk. Conversely, bundling sometimes results in populations that cannot afford flood cover becoming exposed to
other perils.
