(1) Realized gain (loss) on available for sale securities is reported in the Interest income and miscellaneous expense line of the Consolidated
Statements of Income for fiscal 2018.
(2) Amortization (gain) of defined benefit plan items are reported in the Interest income and miscellaneous expense line of our Consolidated Statements of Income.
(3) The effective portion of gain or loss on net debt designated as non-derivative net investment hedging instruments is recognized in Accumulated Other Comprehensive Income and is reclassified to income in the same period when a gain or loss related to the net investment is included in income.
(4) As a result of the adoption of ASC 2016-01 we recorded a cumulative effect adjustment to our opening fiscal 2019 retained earnings balance that increased retained earnings and decreased accumulated other comprehensive income. See Note 1 titled, "Nature of Operations and Summary of Significant Accounting Policies" for further details.
