[1] "All other" revenue relates to royalty income that was not allocated to MP or IDP for fiscal 2018. As a result of the adoption of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," income related to a right-to-use license of intellectual property was recognized at a point-in-time and, therefore, was included as a transition adjustment impacting retained earnings.
