REINSURANCE

In the normal course of business, NSFC seeks to reduce the loss that may arise from catastrophes or other events that cause unfavorable underwriting results by reinsuring certain levels of risk in various areas of exposure with other insurance enterprises or reinsurers.  NSFC maintains a catastrophe reinsurance agreement to cover losses from catastrophic events, primarily hurricanes.
 
Under the catastrophe reinsurance program, the Company retains the first $4,000,000 in losses from each event.  Reinsurance is maintained in four layers as follows:

Layer
Reinsurers' Limits of Liability
First Layer
95% of  $6,000,000 in excess of $4,000,000
Second Layer
95% of  $7,500,000 in excess of $10,000,000
Third Layer
100% of  $25,000,000 in excess of $17,500,000
Fourth Layer
100% of  $30,000,000 in excess of $42,500,000


Layers 1-4 cover events occurring from January 1-December 31 of the contract year.  All significant reinsurers under the program carry A.M. Best ratings of A- (Excellent) or higher, or equivalent ratings.

Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policy.  Amounts paid for prospective reinsurance contracts are reported as prepaid reinsurance premiums and amortized over the remaining contract period.

In the normal course of business, NSIC seeks to limit its exposure to loss on any single insured and to recover a portion of benefits paid by ceding reinsurance to other insurance enterprises or reinsurers under excess coverage contracts.  NSIC retains a maximum of $50,000 of coverage per individual life.  The cost of reinsurance is amortized over the contract period of the reinsurance.
