The following tables provide information by level for the retirement benefit plan assets that are measured at fair value, as defined by U.S. GAAP. See Note 1 for discussion of the fair value measurement terms of Levels 1, 2, and 3. In accordance with authoritative guidance adopted in fiscal year 2017, certain investments for which the fair value is measured using the net asset value per share (or its equivalent) practical expedient are not presented within the fair value hierarchy. The fair value amounts presented for these investments are intended to permit reconciliation to the total fair value of plan assets at April 28, 2017 and April 29, 2016. The revised presentation has been applied retrospectively and fiscal year 2016 values have been reclassified to conform to classifications used in the current year. U.S. Pension Benefits
