Starting in the first quarter of 2020, we have updated our product category revenue reporting format.  These changes are designed to further align with our recent reorganization.  Product category sales include the following changes:

• Surgical products, previously reported in the S.E.T. (Sports Medicine, Extremities and Trauma) product category, are included in the Other product category;

• Dental products are combined with Spine and CMF (Craniomaxillofacial) products into one product category;

• The CMF product category name has been changed to CMFT (Craniomaxillofacial and Thoracic), to reflect the Thoracic business, which is included in that category; and

• Other immaterial adjustments related to brand alignment within product categories in the Asia Pacific region have been made.

Prior period product category sales have been reclassified to conform to the current presentation.
