+Added: (a) Change in Presentation.
+Added: The Company has changed its Consolidated Statements of Operations to separately present (income) loss from investments held in employee deferred compensation trusts.
+Added: Under the Company’s employee deferred compensation plans, employees direct the investment of their account balances, and the Company invests amounts held in the associated investment trusts consistent with these directions.
+Added: As realized and unrealized investment gains and losses occur, the Company’s deferred compensation obligation to employees changes accordingly.
+Added: However, the value of the related investment trust assets also changes by an equal and offsetting amount, leaving no net cost to the Company.
+Added: Under the new presentation, changes in the Company’s employee deferred compensation obligations remain in selling, general and administrative expenses or, in the case of risk consulting and internal audit services, costs of services.
+Added: However, the offsetting changes in the investment trust assets will be presented separately below selling, general and administrative expenses.
+Added: This does not change the previously reported levels of pre-tax or after-tax income or cash flow.
Compared sentence by sentence after normalising whitespace, quotation marks, case and digits, so re-formatting and restated figures do not read as changed language. Wording changes appear as one removal and one addition. The current filing and the prior one are authoritative.
