A test that is undertaken annually to ensure that members of the Society have sufficient eligible assets to meet their underwriting liabilities. The test is undertaken at member level and also on an aggregate basis for all members taking in account the centrally held assets of the Society such as the New Central Fund. Any member that fails the solvency test at member level will be required to provide additional funds or cease underwriting. The centrally held assets of the Society must be sufficient to cover any shortfall of assets at member level.
