expenditures, distributions and repurchases; and increased flexibility and capacity for permitted investments and acquisitions by the  Company. The principal amount, maturity and amortization terms of the term loan were not changed by the amendments, with the  exception of amounts required to be paid with defined excess cash flow. The LIBOR floor of 1.25% represents an embedded interest rate derivative that requires bifurcation, where the bifurcated amount is carried  at fair value  (note 22) . Under the term facility, the Company made a required mandatory prepayment in the first quarter of 2013 of its defined excess cash flow  relating to fiscal 2012. The agreement requires the prepayment to be applied in the direct order of maturity of the remaining repayments  due for the twenty-four months following the relevant mandatory prepayment event, and thereafter, ratably to the remaining repayments.  Accordingly, there is no current portion of the term debt due as no payments are required in the next twelve months. The principal payments required on long-term debt and finance leases are as follows: For the fifty-two weeks ended December 28, 2013 and December 29, 2012, the expected return on plan assets was calculated using the  same interest rate as applied for the purpose of discounting the defined benefit obligation. The amended standard  (note 3)  increased the  estimated fiscal 2013 net benefit expense to $1.7 million. The adjustment required for the fifty-two weeks ended December 29, 2012, was  nominal. In Canada, the Company maintains a defined contribution plan and two active defined benefit pension plans covering all Canadian  employees. With respect to U.S. employees, the Company’s subsidiary maintains a defined contribution plan (401(k)) that covers all U.S. employees. In Canada, the Company also sponsors a non-pension benefit plan for employees hired before May 19, 1993. This benefit is a paid-up life  insurance policy or a lump sum payment based on the employee’s final earnings at retirement. Effective December 31, 1999, the Company introduced a new defined contribution pension plan for all Canadian salaried employees  including new Named Executive Officers (“NEOs”). In the U.S., the Company maintains a defined contribution savings plan under the provisions of the Employment Retirement Income  Security Act of 1974 (a 401(k) plan), which covers substantially all employees of the Company’s U.S. subsidiary, including U.S. NEOs. In  fiscal 2013, NEOs were permitted to contribute up to 20% of their base pay, to a maximum of $16.5 thousand (employees over 50 years of age  could contribute an additional $5.5 thousand). The Company also makes a safe harbor matching contribution equal to 100% of their salary  deferrals (contributions to the plan) that do not exceed 3% of their compensation plus 50% of salary deferrals between 3% and 5% of their  salary compensation.
