Cloud Services & Digital Media Metrics (includes Consensus and Divested Assets)

1. Cloud Services revenue includes IP Licensing revenue; Q3 2020 Cloud Services Revenue excludes projected September revenues and EBITDA for the divested Voice ANZ asset; all periods include the B2B Backup and UK Voice businesses
2. Cloud Services Customers are defined as paying DIDs for Fax & Voice services and direct and resellers' accounts for other services
3. Quarterly Average Revenue per Customer is calculated using our standard convention of applying the average of the quarter's beginning and ending customer base to the total revenue of the quarter; Q2 2019 assumes NetProtect acquisition closed on March 31, instead of April 2, 2019
4. User cancel rate, also called user churn, is defined as cancellation of service by Cloud Business customers with greater than four months of continuous service (continuous service includes Cloud Business customers that are administratively cancelled and reactivated within the same calendar month). User cancel rate is calculated monthly and expressed here as an average over the three months of the quarter
5. Digital Media Traffic figures based on Google Analytics & Partner Platforms; To more accurately reflect customer activity at Ookla, we have shifted to using tests as the basis instead of Google Analytics, resulting in pro-forma adjustments to data from Q4

2019 through Q4 2020
