Concentrations of Credit Risk [Abstract]

Concentrations of Credit Risk

19.Concentrations of Credit Risk:

We maintain cash and cash equivalents in accounts with four financial institutions in excess of the amount insured by the Federal Deposit Insurance Corporation. We monitor the financial stability of the depository institutions regularly and do not believe excessive risk of depository institution failure existed at December 31, 2018.

We are also subject to credit risk with respect to reinsurers to whom we have ceded underwriting risk. Although a reinsurer is liable for losses to the extent of the coverage it assumes, we remain obligated to our policyholders in the event that the reinsurers do not meet their obligations under the reinsurance agreements. In order to mitigate credit risk to reinsurance companies, we monitor the financial condition of reinsurers on an ongoing basis and review our reinsurance arrangements periodically. Most of our reinsurance recoverable balances as of December 31, 2018 were with reinsurers that had an A.M. Best rating of “A-” or better. We also mitigate our credit risk for the remaining reinsurance recoverable by obtaining letters of credit.
