[1] Pension benefit payments in fiscal 2015 includes $10,000 of lump sum distributions that were made to certain terminated vested employees as a settlement of the employees' pension obligations. These distributions did not meet the threshold to qualify as a settlement under U.S. GAAP and therefore, no unamortized actuarial loss was recognized in the Statement of Income upon completion of the lump sum distributions.
