As per Standard Life 2005, an amount of approximately GBP19.8 million may have been paid on about 342 critical illness claims. More precisely, a sum of around GBP 58,000 may have been disbursed per claim. Furthermore, during the year 2005, around 82 percent of critical illness claims may have been awarded in contrast to nearly 80 percent of the previous year. Moreover, 18 percent of claims may have been declined. Not meeting policy definitions may have accounted for around 10 percent of critical illness claims being turned down. On the other hand non disclosure may have brought around 8 percent of declined cases.

Additionally, Skandia, one of the leaders in the critical illness market has pulled the curtain on its report about critical illness claims as from February 2007. They affirm having paid around 1920 claims summing up to an amount of around GBP182 million. They also revealed that the average age of claimants may have been more likely to be 46. However, the most common critical illness claims may have been cancer, around 58 percent, heart attack, around 15 percent, heart surgery around 8 percent and stroke around 7 percent. More statistics show that the most common forms of cancer more likely claimed for may have been: breast cancer, around GBP23million, lower intestine nearly GBP11 million, malignant melanoma about GBP9 million and prostate approximately GBP7 million. In addition to, they may have paid around 88 percent of claims while the remaining 12 percent could have been rejected as they did not match policy criteria or non disclosure.

Furthermore, as per Munich Re, if reinsurance is carried out on a surplus basis, it may be advisable to fix only a retention for the life risk. The critical illness risk may then be reinsured in the same proportion as the corresponding life risk. For example, the insurer might want to retain all life risks up to an amount of USD 50,000. A policy with USD 200,000 life sum insured and 50 percent prepayment in the case of critical illness would be reinsured as follows: The excess of USD 150,000 over the life risk retention, i.e. 75 percent of the total sum, could be assumed by the reinsurer. The critical illness risk may then be reinsured in the same proportion. In the case of a critical illness claim, the reinsurer may pay out USD 75,000 (75 percent of 50 percent of USD 200,000) and another USD 75,000 (75 percent of [USD 200,000?USD 100,000]) on subsequent death, or USD 150,000 (75 percent of USD 200,000) if death occurs first

One aspect of critical illness cover may be the quota share reinsurance. For example, the insurer might reinsure 30 percent of its life and prepayment critical illness business. In case of a reinsured policy with USD 200,000 life sum insured and a critical illness acceleration benefit of 50 percent, the reinsurer may pay USD 30,000 (30 percent of 50 percent of USD 200,000) upon critical illness and another USD 30,000 (30 percent of [USD 200,000?USD 100,000]) succeeding death, or USD 60,000 (30 percent of USD 200,000) if death occurred first.
