In some markets, however, the definition of a claim for many of the diseases and conditions have become standardised, thus all insurers would use the same claims definition. The standardisation of the claims definitions may serve many purposes including increased clarity of cover for policyholders and greater comparability of policies from different life offices. For example, in the UK the Association of British Insurers (ABI) has issued a Statement of Best Practise which includes a number of standard definitions for common critical illnesses.
