On May 22, 2017, the Company issued $400 million of unsecured 4.20% Senior Notes (4.20% Notes) that mature on May 15, 2047. The 4.20% Notes require no principal payments until the maturity date and interest is payable semi-annually on May 15 and November 15, beginning on November 15, 2017. Prior to November 15, 2046, the Company may redeem the 4.20% Notes in whole at any time or gradually at a “make-whole” redemption price. This redemption price is calculated by reference to the then-current yield on a U.S. treasury security with a maturity comparable to the remaining term of the 4.20% Notes plus 20 basis points, together with accrued and unpaid interest, if any, at the redemption date. Additionally, if the Company experiences specific kinds of changes in control, it will be required to make an offer to purchase the 4.20% Notes at 101% of their principal amount plus accrued and unpaid interest, if any, at the date of purchase. Costs and discounts of approximately $5.8 million associated with the issuance of the 4.20% Notes, representing underwriting fees and other expenses, have been recorded as a contra-liability within Long-term debt and will be amortized to interest expense over the term of the 4.20% Notes.

The estimated fair value of the Company’s 4.20% Notes, 3.75% Senior Notes due 2046 (3.75% Notes) and 4.60% Senior Notes due 2045 (4.60% Notes) was based on available external pricing data and current market rates for similar debt instruments, among other factors, which are classified as level 2 inputs within the fair value hierarchy. The fair value of the 4.20% Notes was approximately $410 million as of June 30, 2017. The fair value of the 3.75% Notes was approximately $384 million and $371 million as of June 30, 2017 and December 31, 2016, respectively. The fair value of the 4.60% Notes was approximately $1.1 billion as of June 30, 2017 and December 31, 2016, respectively. The carrying value of other long-term debt approximates fair value due to their variable interest rates.
