(1) Estimates and Assumptions: The preparation of financial statements in conformity with GAAP requires us to make various estimates and assumptions that affect the reporting of net periodic benefit cost, plan assets and plan obligations for each plan at the date of the financial statements. Actual results could differ from these estimates. One significant estimate relates to the calculation of the benefit obligation for each plan. We annually establish the discount rate, which is an estimate of the interest rate at which these benefits could be effectively settled, that is used to determine the present value of the respective plan's benefit obligations as of December 31.
