Letter of Credit. Peach Re maintains a Credit Facility Agreement with Deutsche Bank (the “Credit Facility Agreement”) to support certain obligations for a portion of the reserves (commonly referred to as Regulation XXX reserves) related to level premium term life insurance policies ceded to Peach Re from Primerica Life under the Peach Re Coinsurance Agreement.

Under the Credit Facility Agreement, Deutsche Bank issued a letter of credit in the initial amount of $450.0 million with a term expiring on December 31, 2025 (the “LOC”) for the benefit of Primerica Life, the direct parent of Peach Re. Subject to certain conditions, the amount of the LOC periodically increased up to a maximum amount of approximately $507.0 million, which was reached in 2014. As of December 31, 2018, the amount outstanding under the LOC was $299.6 million. This amount will continue to decline over the remaining term of the LOC to correspond with declines in the Regulation XXX reserve. Pursuant to the terms of the Credit Facility Agreement, in the event amounts are drawn under the LOC by Primerica Life, Peach Re will be obligated, subject to certain limited conditions, to reimburse Deutsche Bank for the amount of any draws and interest thereon. Peach Re has collateralized its obligations to Deutsche Bank by granting it a security interest in all of its assets with the exception of amounts held in a special account established to meet minimum asset thresholds required by state regulatory authorities. As of December 31, 2018, the Company was in compliance with all financial covenants under the Credit Facility Agreement.

Contingent Liabilities. The Company is involved from time to time in legal disputes, regulatory inquiries and arbitration proceedings in the normal course of business. These disputes are subject to uncertainties, including the large and/or indeterminate amounts sought in certain of these matters and the inherent unpredictability of litigation. As such, the Company is unable to estimate the possible loss or range of loss that may result from these matters unless otherwise indicated.

The Company is currently undergoing multi-state unclaimed property audits by 30 jurisdictions, currently focusing on the life insurance claims paying practices of its subsidiaries, Primerica Life and NBLIC. Other jurisdictions may pursue similar audits. The potential outcome of such audits is difficult to predict but could subject the Company to adverse consequences, including, but not limited to, settlement payments, additional payments to beneficiaries and additional escheatment of funds deemed abandoned under state laws. At this time, the Company cannot reasonably estimate the likelihood or the impact of additional costs or liabilities that could result from the resolution of these matters.
