On April 19, 2018, the Company entered into an amended and restated credit agreement with a syndicate of banks to provide a multi-currency senior unsecured revolving credit facility (the “Revolving Credit Facility”) of $1,000,000. The Revolving Credit Facility has a 5 -year term ending April 30, 2023 and bears interest at an applicable margin of 1.25% to 2.50% over floating reference rates, depending on financial leverage ratios. The weighted average interest rate for 2018 was 3.0% ( 2017 – 2.9% ). The Revolving Credit Facility had $562,386 of available un-drawn credit as at December 31, 2018. As of December 31, 2018, letters of credit in the amount of $7,624 were outstanding ( $10,307 as at December 31, 2017). The Revolving Credit Facility requires a commitment fee of 0.25% to 0.5% of the unused portion, depending on certain leverage ratios. At any time during the term, the Company has the right to increase the Revolving Credit Facility by up to $250,000 on the same terms and conditions. On May 17, 2018, the Company entered into a note purchase agreement with a group of institutional investors to issue €210,000 of senior unsecured notes with a fixed interest rate of 2.23% (the “Senior Notes”). The proceeds from the Senior Notes were received on May 30, 2018 and were used to repay indebtedness under the Facility. The Senior Notes have a 10 -year term ending May 30, 2028. The Revolving Credit Facility and the Senior Notes rank equally in terms of seniority and have similar financial covenants. The Company is required to maintain financial covenants including leverage and interest coverage. The Company was in compliance with these covenants as of December 31, 2018. The Company is limited from undertaking certain mergers, acquisitions and dispositions without prior approval. The effective interest rate on the Company’s long-term debt for the year ended December 31, 2018 was 3.3% ( 2017 – 3.1% ). The estimated aggregate amount of principal repayments on long-term debt required in each of the next five years ending December 31 and thereafter to meet the retirement provisions are as follows :
| 2019 |  | $ | 1,834 |  |
| 2020 |  |  | 348 |  |
| 2021 |  |  | 198 |  |
| 2022 |  |  | - |  |
| 2023 and thereafter |  |  | 669,743 |  |
