[1] During the first quarter of fiscal 2019, the Company adopted a comprehensive new revenue recognition standard using a modified retrospective method that does not restate prior periods to be comparable to the current period presentation. The adoption of this guidance primarily impacted the presentation of advertising contributions received from the Company’s licensees and the related advertising expenditures incurred by the Company. The adoption of this guidance resulted in an increase in net royalty revenue within the Company’s Licensing segment of $2.1 million, as well as an increase in SG&A expenses in our Americas Retail, Americas Wholesale and Licensing segments as well as corporate overhead of $0.5 million, $0.2 million, $0.2 million and $0.5 million, respectively, during the three months ended August 4, 2018 compared to the same prior-year period. The net favorable impact on earnings from operations was approximately $0.6 million during the three months ended August 4, 2018 compared to the same prior-year period. During the six months ended August 4, 2018, the adoption of this guidance resulted in an increase in net royalty revenue within the Company’s Licensing segment of $4.4 million, as well as an increase in SG&A expenses in our Americas Retail, Americas Wholesale and Licensing segments as well as corporate overhead of $2.3 million, $0.9 million, $0.4 million and $1.1 million, respectively, during the six months ended August 4, 2018 compared to the same prior-year period. The net unfavorable impact on earnings from operations was approximately $0.4 million during the six months ended August 4, 2018 compared to the same prior-year period. Refer to Note 1 for more information regarding the impact from the adoption of this new standard.

[2] During the fourth quarter of fiscal 2018, the Company reclassified net royalties received on the Company’s inventory purchases of licensed product from net revenue to cost of product sales to reflect its treatment as a reduction of the cost of such licensed product. Accordingly, net revenue for the three and six months ended July 29, 2017 has been adjusted to conform to the current period presentation. This reclassification had no impact on previously reported earnings (loss) from operations.

[3] During the first quarter of fiscal 2019, the Company adopted new authoritative guidance which requires that the non-service components of net periodic defined benefit pension cost be presented outside of earnings (loss) from operations. Accordingly, earnings (loss) from operations and segment results for the three and six months ended July 29, 2017 have been adjusted to conform to the current period presentation.
