The Insurance (Prudential Supervision) Act 2010 requires all New Zealand health insurers to be given a Financial Strength Rating.

AM Best has assessed Union Medical Benefits Society Limited (UniMed) as having A (Excellent) Financial Strength Rating.

AM Best’s Financial Strength ratings are as follows:

Secure: A++, A+ (Superior), A, A- (Excellent), B++, B+ (Good)

Vulnerable: B, B- (Fair), C++, C+ (Marginal), C, C- (Weak), D (Poor), E (Under Regulatory Supervision), F (In Liquidation), S (Suspended)

A condition of being a licensed insurer is that UniMed is subject to the solvency margin requirements of the Solvency Standard for non-life insurance businesses as issued by the RBNZ. This standard requires UniMed to retain a solvency margin of greater than zero, meaning that the actual solvency capital position exceeds the minimum required under the standard.

UniMed complies with all externally imposed capital requirements.

As at 31 December 2019

Actual solvency capital: $137,405,821
Minimum solvency capital: $25,144,205
Solvency margin: $112,261,617
Solvency coverage ratio: 546%

The solvency ratio is the actual solvency capital divided by minimum solvency capital required.
