(1) The increases in the allowances and accruals for cooperative marketing arrangements, customer incentive programs, pricing programs as of March 31, 2018 compared with March 31, 2017 were primarily the result of increases in pricing programs and incentive and marketing activities.

(2) The increase in deferred tax assets was primarily due to the adoption of ASU 2016-09 effective April 1, 2017, partially offset by the remeasurement of federal and state deferred tax assets in fiscal year 2018 as a result of the enactment of the Tax Act on December 22, 2017.
