Senior Notes On May 16, 2016, the Company issued $400 million of unsecured 3.75% Senior Notes (3.75% Notes) that mature on May 15, 2046. The 3.75% 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, 2016. Prior to November 15, 2045, the Company may redeem the 3.75% Notes in whole at any time or in part from time to time 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 3.75% Notes plus 20 basis points, together with accrued and unpaid interest, if any, to 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 3.75% Notes at 101% of their principal amount plus accrued and unpaid interest, if any, to the date of purchase. On or after November 15, 2045, the Company may redeem the 3.75% Notes in whole at any time or in part from time to time at 100% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. Costs and discounts of approximately $7 million associated with the issuance of the 3.75% 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 3.75% Notes. The fair value of the 3.75% Notes was approximately $371 million as of December 31, 2016. On June 11, 2015, the Company issued $1 billion of unsecured 4.60% Senior Notes (4.60% Notes) that mature on June 15, 2045. The 4.60% Notes require no principal payments until the maturity date and interest is payable semi-annually on June 15 and December 15, beginning on December 31, 2015. Prior to December 15, 2044, the Company may redeem the 4.60% Notes in whole at any time or in part from time to time 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 4.60% Notes plus 25 basis points, together with accrued and unpaid interest, if any, to 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 4.60% Notes at 101% of their principal amount plus accrued and unpaid interest, if any, to the date of purchase. On or after December 15, 2044, the Company may redeem the 4.60% Notes in whole at any time or in part from time to time at 100% of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. Costs and discounts of approximately $11 million associated with the issuance of the 4.60% 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 4.60% Notes. The fair value of the 4.60% Notes was approximately $1.1 billion and $1 billion as of December 31, 2016 and 2015, respectively. The estimated fair value of the Company’s 3.75% Notes and 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 carrying value of other long-term debt approximates fair value due to the variable interest rates. U.S. Dollar Term Loan In January 2016, the Company exercised its option to prepay the U.S. dollar loan and paid off the remaining balance of the loan. British Pound Term Loan and Revolving Credit Facility On August 26, 2015, the Company entered into an unsecured credit facilities agreement providing for a five-year term loan of £160 million and revolving credit facility of £20 million. Proceeds of the term loan were used to partially fund the acquisition of Cromwell and to pay certain costs related to the acquisition. Under the agreement, the principal amount of the term loan will be repaid semiannually in installments of £4 million beginning February 2016 through February 2020 with the remaining outstanding amount due August 2020. At the election of the Company, the term loan bears interest at the London Interbank Offered Rate (LIBOR) Rate plus the Applicable Margin as defined within the term loan agreement. At December 31, 2016, the Company had elected a one-month LIBOR Interest Period. The weighted average interest rate was 1.17% and 1.26% for the years ended December 31, 2016 and 2015, respectively. The Company has the right to obtain advances under the revolving credit facility, which will be used for general corporate and working capital purposes. Pursuant to the credit agreement, there is a commitment fee of 0.26% as of December 31, 2016. There is no balance outstanding on the revolving credit facility as of December 31, 2016. Euro Term Loan and Revolving Credit Facility On August 31, 2016, the Company entered into an agreement for a five year term loan of €110 million and a revolving credit facility of up to €20 million. The proceeds from the term loan were used to pay in full €102.5M of a term loan that matured in August 2016, which was entered into to partially fund the acquisition of Fabory in 2011. Under the agreement, no principal amount of the loan will be required to be paid until the loan becomes due on August 31, 2021, at which time the loan will be required to be paid in full. The Company, at its option, may prepay this term loan in whole or in part at the end of any interest period without penalty. The loan bears interest at the Euro Interbank Offered Rate (EURIBOR) plus a margin of 45 basis points. If EURIBOR is less than zero, then EURIBOR will be deemed to be zero. The interest rate at December 31, 2016, was 0.45%. Costs of approximately €0.5 million associated with the issuance of the term loan, representing arrangement fees and other expenses, have been recorded as a contra-liability within Long-term debt and will be amortized to interest expense over the life of the term loan. The revolving credit facility must generally be paid at the conclusion of each interest period as defined in the facility agreement. This facility will bear interest at EURIBOR plus a margin of 35 basis points. The Company has the right to obtain advances under the revolving credit facility, which will be used for general corporate and working capital purposes. Pursuant to the credit agreement, there is a commitment fee of 0.1225% as of December 31, 2016. There is €5M outstanding on the revolving credit facility as of December 31, 2016. The interest rate on the outstanding amount at December 31, 2016, was 0.35%. Canadian Dollar Revolving Credit Facility In September 2014, the Company entered into an unsecured revolving credit facility with a maximum availability of C$175 million. Pursuant to the credit agreement, there is a commitment fee of 0.07% as of December 31, 2016, and the facility matures on September 24, 2019. As of December 31, 2016 and 2015, the Company had drawn C$135 million and C$150 million, respectively, under the facility for the purpose of repaying an intercompany loan and to fund general working capital needs. The weighted average interest rate during the year on this outstanding amount was 1.59%. No principal payments are required on the credit facility until the maturity date. The scheduled aggregate principal payments related to long-term debt, excluding debt issuance costs, are due as follows (in thousands of dollars):
Year |  | Payment Amount |
2017 |  | $ | 19,966 |
2018 |  | 29,339 |
