At December 31, 2018, we had $375.0 million in principal amount of publicly-traded, senior unsecured notes (the “Senior Notes”). The Senior Notes were issued in 2012 at a price of 99.843% of the principal amount with an annual interest rate of 4.75%, payable semi-annually in arrears on January 15 and July 15, and are scheduled to mature on July 15, 2022. As of December 31, 2018, we were in compliance with the covenants of the Senior Notes. No events of default occurred on the Senior Notes during the year ended December 31, 2018.

As unsecured senior obligations, the Senior Notes rank equally in right of payment with all existing and future unsubordinated indebtedness and senior to all existing and future subordinated indebtedness of the Parent Company. The Senior Notes are structurally subordinated in right of payment to all existing and future liabilities of our subsidiaries. In addition, the Senior Notes contain covenants that restrict our ability to, among other things, create or incur any indebtedness that is secured by a lien on the capital stock of certain of our subsidiaries, and merge, consolidate or sell all or substantially all of our properties and assets.

Surplus Note. At December 31, 2018, the principal amount outstanding on the Surplus Note issued by Vidalia Re was $970.4 million, which is equal to the principal amount of the LLC Note. The principal amount of both the Surplus Note and the LLC Note will fluctuate over time to coincide with the amount of policy reserves being contractually supported under the Vidalia Re Coinsurance Agreement. Both the LLC Note and the Surplus Note mature on December 31, 2030 and bear interest at an annual interest rate of 4.50%. Based on the estimated reserves for policies issued in 2011 through 2017 that have been ceded under the Vidalia Re Coinsurance Agreement, the principal amounts of the Surplus Note and the LLC Note are expected to reach $1.5 billion each. This financing arrangement is non-recourse to the Parent Company and Primerica Life, meaning that neither of these companies has guaranteed the Surplus Note or is otherwise liable for reimbursement for any payments triggered by the LLC Note’s credit enhancement feature. The Parent Company has agreed to support Vidalia Re’s obligation to pay the credit enhancement fee incurred on the LLC Note. See Note 4 (Investments) for more information on the LLC Note.

Revolving Credit Facility. We maintain an unsecured $200.0 million revolving credit facility ("Revolving Credit Facility") with a syndicate of commercial banks that has a scheduled termination date of December 19, 2022. Amounts outstanding under the Revolving Credit Facility bear interest at a periodic rate equal to LIBOR or the base rate, plus in either case an applicable margin. The Revolving Credit Facility also permits the issuance of letters of credit. The applicable margins are based on our debt rating with such margins for LIBOR rate loans and letters of credit ranging from 1.125% to 1.625% per annum and for base rate loans ranging from 0.125% to 0.625% per annum. Under the Revolving Credit Facility, we incur a commitment fee that is payable quarterly in arrears and is determined by our debt rating. This commitment fee ranges from 0.125% to 0.225% per annum of the aggregate $200.0 million commitment of the lenders under the Revolving Credit Facility. As of December 31, 2018, no amounts have been drawn under the Revolving Credit Facility and we were in compliance with its covenants. Furthermore, no events of default have occurred under the Revolving Credit Facility during the year ended December 31, 2018.
