In the first quarter of 2021, we updated our product category revenue reporting.  Product category sales include the following changes:

• Orthopedic robotic capital sales and services, previously reported in the Knee product category, are included in the Other product category;

• Disposable products used in computer-assisted surgeries, previously reported in the Other product category, are included in the Knees product category;

• CMFT (Craniomaxillofacial and Thoracic) products, previously reported in the Dental, Spine & CMFT category, are included in the S.E.T. (Sports Medicine, Extremities and Trauma) product category;

• CMFT has been removed from the Dental, Spine & CMFT product category and the name has been changed to Dental & Spine to reflect the revenue related to the spin off of SpinCo;

• Office based technologies products, previously reported in the Other product category, are included in the Dental & Spine product category;

• Other immaterial adjustments across product categories related to brand alignment.

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