4.	DEBT AND CAPITAL LEASE OBLIGATIONS

Debt

During the six months ended June 30, 2018, the following activity occurred:

•

We issued in a public offering $750 million aggregate principal amount of our 4.35 percent Senior Notes due June 1, 2028. Gross proceeds from this debt issuance were $749 million before deducting the underwriting discount and other debt issuance costs totaling $7 million. The proceeds were used to redeem our 9.375 percent Senior Notes due March 15, 2019 (9.375 percent Senior Notes) for $787 million, which includes an early redemption fee of $37 million that was charged to other income (expense), net.

•

VLP issued in a public offering $500 million aggregate principal amount of its 4.5 percent Senior Notes due March 15, 2028. Gross proceeds from this debt issuance were $498 million before deducting the underwriting discount and other debt issuance costs totaling $5 million. The proceeds are available only to the operations of VLP and were used to repay the outstanding balance of $410 million on VLP’s $750 million senior unsecured revolving credit facility (the VLP Revolver) and $85 million of its notes payable to us, which is eliminated in consolidation.

•

Central Mexico Terminals, which is the name used by us to refer to one of our consolidated variable interest entities (VIEs) and which is further described and defined in Note 7, entered into a combined $340 million unsecured revolving credit facility (IEnova Revolver) with IEnova (defined in Note 7). Central Mexico Terminals borrowed $56 million and had no repayments under the IEnova Revolver. The IEnova Revolver matures in February 2028. However, IEnova may terminate the IEnova Revolver at any time and demand repayment of all outstanding amounts; therefore, such amounts are reflected in current portion of debt. The IEnova Revolver is available only to the operations of Central Mexico Terminals, and the creditors of Central Mexico Terminals do not have recourse against Valero.

Outstanding borrowings under the IEnova Revolver bear interest at the three-month LIBO rate for the applicable interest period in effect from time to time plus the applicable margin. The interest rate under the IEnova Revolver is subject to adjustment, with agreement by both parties, based upon changes in market conditions. As of June 30, 2018, the variable rate was 5.958 percent.
