DEFINITIONS & ADDITIONAL INFORMATION LIBERTY LATIN AMERICA ADJUSTED OIBDA MARGIN Calculated by dividing Adjusted OIBDA by total revenue for the applicable period. FMC Fixed-Mobile Convergence. FULLY-SWAPPED BORROWING COST Represents the weighted average interest rate on our debt (excluding finance leases and including vendor financing obligations), including the effects of derivative instruments, original issue premiums or discounts, which includes a discount on the convertible notes issued by Liberty Latin America associated with a conversion option feature, and commitment fees, but excluding the impact of financing costs. INTERNET (BROADBAND) RGU A home, residential multiple dwelling unit or commercial unit that receives internet services over our network. MOBILE SUBSCRIBERS Our mobile subscriber count represents the number of active subscriber identification module ("SIM") cards in service rather than services provided. For example, if a mobile subscriber has both a data and voice plan on a smartphone this would equate to one mobile subscriber. Alternatively, a subscriber who has a voice and data plan for a mobile handset and a data plan for a laptop (via a dongle) would be counted as two mobile subscribers. Customers who do not pay a recurring monthly fee are excluded from our mobile telephony subscriber counts after periods of inactivity ranging from 30 to 90 days, based on industry standards within the respective country. In a number of countries, our mobile subscribers receive mobile services pursuant to prepaid contracts. Our Liberty Puerto Rico segment prepaid subscriber count includes mobile reseller subscribers, which represent organizations that purchase minutes and data at wholesale prices and subsequently resell it under the purchaser's brand name. These reseller subscribers result in a significantly lower ARPU than the remaining subscribers included in our prepaid balance. Additionally, our Liberty Puerto Rico segment postpaid subscriber count includes CRUS, which represent an individual receiving mobile services through an organization that has entered into a contract for mobile services with us and where the organization is responsible for the payment of the CRU's mobile services. REVENUE GENERATING UNIT ("RGU") RGU is separately a video RGU, internet RGU or telephony RGU. A home, residential multiple dwelling unit, or commercial unit may contain one or more RGUS. For example, if a residential customer in Puerto Rico subscribed to our video service, fixed-line telephony service and broadband internet service, the customer would constitute three RGUS. RGUS are generally counted on a unique premises basis such that a given premises does not count as more than one RGU for any given service. On the other hand, if an individual receives one of our services in two premises (e.g., a primary home and a vacation home), that individual will count as two RGUS for that service. Each bundled video, internet or telephony service is counted as a separate RGU regardless of the nature of any bundling discount or promotion. Non-paying subscribers are counted as RGUS during their free promotional service period. Some of these subscribers may choose to disconnect after their free service period. Services offered without charge on a long-term basis (e.g., VIP subscribers or free service to employees) generally are not counted as RGUS. We do not include subscriptions to mobile services in our externally reported RGU counts. In this regard, our RGU counts exclude our separately reported postpaid and prepaid mobile subscribers. U.S. GAAP Generally accepted accounting principles in the United States. LIBERTY LATIN AMERICA | MAY 2023 223
