  Our financial instruments that are not re-measured at fair value include accounts receivable, financing receivables, other 
  
  receivables, digital assets, accounts payable, accrued liabilities, customer deposits and debt. The carrying values of these 
  financial instruments materially approximate their fair values, other than our 2.00% Convertible Senior Notes due in 2024 
  (“2024 Notes”), which matured in the second quarter of 2024, and digital assets. 
  
  We estimated the fair value of the 2024 Notes using commonly accepted valuation methodologies and market-based risk 
  measurements that are indirectly observable, such as credit risk (Level II). In addition, we estimate the fair values of our digital

  carrying values (in millions):
