[1] No new leases were entered into during the nine months ended September 30, 2019.  Amounts shown are due to the adoption of ASC 842 and one lease modification during the three months ended September 30, 2019 that resulted in a noncash remeasurement of the related right-of-use asset and operating lease liability. Amount shown for the three months ended September 30, 2019 reflects the change in balance resulting from such lease modification. Amounts shown for the nine months ended September 30, 2019 reflect balances as of January 1, 2019 for the Healthcare segment (adjusted for lease modification) and as of March 8, 2019 for the Nutrition segment (i.e., the date of our acquisition of Nutrisystem).
