Accounting for revenue Revenue recognition Revenue is recognized at an amount that reflects the consideration to which the Group expects to be entitled in exchange for transferring goods or services to a customer. Post-paid connection fees are derived from the payment of a non-refundable / one-time fee charged to customer to connect to the network (e.g. connection / installation fee). Usually, it does not represent a distinct good or service, and therefore does not give rise to a separate performance obligation and revenue is recognized over the minimum contract duration. However, if the fee is paid by a customer to get the right to receive goods or services without having to pay this fee again over his tenure with the Group (e.g. the customer can readily extend his contract without having to pay the same fee again), it is accounted for as a material right and revenue should be recognized over the customer retention period. Post-paid mobile / cable subscription fees are recognized over the relevant enforceable/subscribed service period (recurring monthly access fees that do not vary based on usage). The service provision is usually considered as a series of distinct services that have the same pattern of transfer to the customer. Remaining unrecognized subscription fees, which are not refunded to the customers, are fully recognized once the customer has been disconnected. Prepaid scratch / SIM cards are services where customers purchase a specified amount of airtime or other credit in advance. Revenue is recognized as the credit is used. Unused credit is carried in the statement of financial position as a contract liability. Upon expiration of the validity period, the portion of the contract liability relating to the expiring credit is recognized as revenue, since there is no longer an obligation to provide those services. Telephone and equipment sales are recognized as revenue once the customer obtains control of the good. That criteria is fulfilled when the customer has the ability to direct the use and obtain substantially all of the remaining benefits from that good. Revenue from provision of Mobile Financial Services (MFS) is recognized once the primary service has been provided to the customer. Customer premise equipment (CPE) are provided to customers as a prerequisite to receive the subscribed Home services and shall be returned at the end of the contract duration. Since CPEs provided over the contract term do not provide benefit to the customer on their own, they do not give rise to separate performance obligations and therefore are accounted for as part of the service provided to the customers. Bundled offers are considered arrangements with multiple deliverables or elements, which can lead to the identification of separate performance obligations. Revenue is recognized in accordance with the transfer of goods or services to customers in an amount that reflects the relative standalone selling price of the performance obligation (e.g. sale of telecom services, revenue over time + sale of handset, revenue at a point in time). Principal-Agent, some arrangements involve two or more unrelated parties that contribute to providing a specified good or service to a customer. In these instances, the Group determines whether it has promised to provide the specified good or service itself (as a principal) or to arrange for those specified goods or services to be provided by another party (as an agent). For example, performance obligations relating to services provided by third-party content providers (i.e., mobile Value Added Services or “VAS”) or service providers (i.e., wholesale international traffic) where the Group neither controls a right to the provider’s service nor controls the underlying service itself are presented net because the Group is acting as an agent. The Group generally acts as a principal for other types of services where the Group is the primary obligor of the arrangement. In cases the Group determines that it acts as a principal, revenue is recognized in the gross amount, whereas in cases the Group acts as an agent revenue is recognized in the net amount. Revenue from the sale of cables, fiber, wavelength or capacity contracts, when part of the ordinary activities of the operation, is recognized as recurring revenue. Revenue is recognized when the cable, fiber, wavelength or capacity has been delivered to the customer, based on the amount expected to be received from the customer. Revenue from operating lease of tower space is recognized over the period of the underlying lease contracts. Finance leases revenue is apportioned between lease of tower space and interest income.

Accounting for cost of sales and operating expenses Cost of sales Cost of sales is recorded on an accrual basis. Customer acquisition costs Specific customer acquisition costs, including dealer commissions and handset subsidies, are charged to marketing expenses when the customer is activated. Operating leases Operating leases are all leases that do not qualify as finance leases. Operating lease payments are recognized as expenses in the consolidated statement of income on a straight-line basis over the lease term. Segmental information Management determines operating and reportable segments based on information used by the chief operating decision maker (CODM) to make strategic and operational decisions from both a business and geographic perspective. The Group’s risks and rates of return are predominantly affected by operating in different geographical regions. The Group has businesses in two main regions: Latin America ("Latam") and Africa. The Latam figures below include Honduras and Guatemala as if they are fully consolidated by the Group, as this reflects the way management reviews and uses internally reported information to make decisions. Honduras and Guatemala are shown under the Latam segment. The joint venture in Ghana is not reported as if fully consolidated. As from January 1, 2018, segment EBITDA includes inter-company management fees and incentive compensation paid to local management teams. These items, were previously included in unallocated corporate costs. This change in presentation has no impact on Group EBITDA. Accordingly, 2017 and 2016 have been represented. Revenue, operating profit (loss), EBITDA and other segment information for the years ended December 31, 2018, 2017 and 2016, were as follows:

Share-based compensation Millicom shares granted to management and key employees includes share-based compensation in the form of long-term share incentive plans. Up until 2015, Millicom had two types of annual plan, a future performance plan and a deferred share plan. In 2015, Millicom issued four different types of plans; a deferred share plan, a performance share plan, an executive share plan and the sign-on CEO share plan (a one-off plan). Since 2016, Millicom has two types of annual plans, a performance share plan and a deferred share plan. The different plans are further detailed below. Cost of share based compensation

Deferred share plan (unchanged since 2014) For the deferred awards plan, participants are granted shares based on past performance, with 16.5% of the shares vesting on January 1 of each of year one and two, and the remaining 67% on 1 January of year three. Vesting is conditional upon the participant remaining employed with Millicom at each vesting date. The cost of this long-term incentive plan, which is not conditional on performance conditions, is calculated as follows: Fair value (share price) of Millicom’s shares at grant date x number of shares expected to vest. Sign-on CEO share plan (issued in 2015 – one off) As part of his employment contract Millicom CEO (from April 1, 2015) received a sign-on grant of 77,344 shares. Vesting is conditional, among other conditions, on the CEO not being dismissed for cause. The cost of this long-term incentive plan, which is not conditional on market conditions, is calculated in the same way as the deferred share plan above. The expense for this plan has been taken in full during 2015. Performance share plan (issued in 2015) Under this plan, shares granted did vest in full in 2018, subject to performance conditions, 62.5% based on Absolute Total Shareholder Return (TSR) and 37.5% based on actual vs budgeted EBITDA minus CAPEX minus Change in Working Capital (Free Cash Flow). As the TSR measure is a market condition, the fair value of the shares in the performance share plan requires consideration of potential adjustments for future market-based conditions at grant date. For this, a specific valuation had been performed at grant date based on the probability of the TSR conditions being met (and to which extent) and the expected payout based upon leaving conditions. The Free Cash Flows (FCF) condition is a non-market measure which had been considered together with the leaving estimate and based initially on a 100% fulfillment expectation. The reference share price for 2015 performance share plan is the same share price as the share price for the deferred share plan. Executive share plan (issued in 2015 – one off) Under this plan, shares were granted to the CEO and CFO based on an allocated holding of 3,333 (CEO) and 2,000 (CFO) shares for which vesting occurs based on three components at multipliers based on market conditions (a TSR for component A and B) and performance conditions (on actual vs budgeted FCF for component C). The maximum number of shares that could vest under the plan was 26,664 (CEO) and 14,000 (CFO). The plan vested in 2018 at the end of a three-year period. Similarly to the performance share plan, a specific valuation had been performed based on the probability of the TSR conditions being met (and to which extent) and the expected payout based upon leaving conditions. The FCF condition being a non-market measure, it had been considered together with the leaving estimate and based initially on a 100% fulfillment expectation. Therefore, the reference share price is the share price on the date that the CEO and the CFO agreed to the executive share plan. Performance share plan (for plans issued in 2016 and 2017) Shares granted under this performance share plan vest at the end of the three-year period, subject to performance conditions, 25% based on Positive Absolute Total Shareholder Return (Absolute TSR), 25% based on Relative Total Shareholder Return (Relative TSR) and 50% based on budgeted Earnings Before Interest Tax Depreciation and Amortization (EBITDA) minus Capital Expenditure (Capex) minus Change in Working Capital (CWC) (Free Cash Flow). This performance share plan is measured similarly to the performance share plan issued in 2015, see above. Performance share plan (for plan issued in 2018) Shares granted under this performance share plan vest at the end of the three-year period, subject to performance conditions, 25% based on Relative Total Shareholder Return (“Relative TSR”), 25% based on the achievement of the Service Revenue target measured on a 3-year CAGRs from years 2018 to 2020 (“Service Revenue”) and 50% based on the achievement of the Operating Free Cash Flow (“Operating Free Cash Flow”) target measured on a 3-year CAGRs from years 2018 to 2020. For the performance share plans and the executive share plan, and in order to calculate the fair value of the TSR portion of those plans, it is necessary to make a number of assumptions which are set out below. The assumptions have been set based on an analysis of historical data as at grant date. Assumptions and fair value of the shares under the TSR portion

The cost of the long-term incentive plans which are conditional on market conditions is calculated as follows: Fair value (market value) of shares at grant date (as calculated above) x number of shares expected to vest. The cost of these plans is recognized, together with a corresponding increase in equity (share compensation reserve), over the period in which the performance and/or employment conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award. Adjustments are made to the expense recorded for forfeitures, mainly due to management and employees leaving Millicom. Non-market performance conditions are not taken into account when determining the grant date fair value of awards, but the likelihood of the conditions being met is assessed as part of the Group’s best estimate of the number of equity instruments that will ultimately vest. No expense is recognized for awards that do not ultimately vest, except for awards where vesting is conditional upon a market condition. These are treated as vested, regardless of whether or not the market conditions are satisfied, provided that all other performance conditions are satisfied. Where the terms of an equity-settled award are modified, as a minimum an expense is recognized as if the terms had not been modified. In addition, an expense is recognized for any modification that increases the total fair value of the share based payment arrangement, or is otherwise beneficial to the employee as measured at the date of modification.

Pension and other long-term employee benefit plans Pension plans The pension plans apply to employees who meet certain criteria (including years of service, age and participation in collective agreements). Pension and other similar employee related obligations can result from either defined contribution plans or defined benefit plans. A defined contribution plan is a pension plan under which the Group pays fixed contributions into a separate entity. No further payment obligations exist once the contributions have been paid. The contributions are recognized as employee benefit expenses when they are due. Prepaid contributions are recognized as assets to the extent that a cash refund or a reduction in future payments is available. Defined benefit pension plans define an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation. The liability recognized in the statement of financial position in respect of the defined benefit pension plan is the present value of the defined benefit obligation at the statement of financial position date less the fair value of plan assets, together with adjustments for unrecognized actuarial gains or losses and past service costs. The defined benefit obligation is calculated annually by independent actuaries. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows, using an appropriate discount rate based on maturities of the related pension liability. Re-measurement of net defined benefit liabilities are recognized in other comprehensive income and not reclassified to the statement of income in subsequent years. Past service costs are recognized in the statement of income on the earlier of the date of the plan amendment or curtailment, and the date that the Group recognizes related restructuring costs. Net interest is calculated by applying the discount rate to the net defined benefit asset/liability. Long-service plans Long-service plans apply for Colombian subsidiary UNE employees with more than five years of service whereby additional bonuses are paid to employees that reach each incremental length of service milestone (from five to 40 years). Termination plans In addition, UNE has a number of employee defined benefit plans. The level of benefits provided under the plans depends on collective employment agreements and Colombian labor regulations. There are no defined assets related to the plans, and UNE make payments to settle obligations under the plans out of available cash balances. At December 31, 2018, the defined benefit obligation liability amounted to $60 million (2017: $66 million) and payments expected in the plans in future years totals $111 million (2017: $87 million). The average duration of the defined benefit obligation at December 31, 2018 is 7 years (2017: 7 years). The termination plans apply to employees that joined UNE prior to December 30, 1996. The level of payments depends on the number of years in which the employee has worked before retirement or termination of their contract with UNE. Except for the UNE pension plan described above, there are no other significant defined benefits plans in the Group. Directors and executive management The remuneration of the members of the Board of Directors comprises an annual fee and shares.

Foreign exchange gains and losses Transactions denominated in a currency other than the functional currency are translated into the functional currency using exchange rates prevailing at the transaction dates. Foreign exchange gains and losses resulting from the settlement of such transactions, and on translation of monetary assets and liabilities denominated in currencies other than the functional currency at year-end exchange rates, are recognized in the consolidated statement of income, except when deferred in equity as qualifying cash flow hedges. Taxation Income tax expense Tax mainly comprises income taxes of subsidiaries and withholding taxes on intragroup dividends and royalties for use of Millicom trademarks and brands. Millicom operations are in jurisdictions with income tax rates of 10% to 40% levied on either revenue or profit before income tax (2017: 10% to 40%; 2016: 10% to 40%).

Current tax assets and liabilities Current tax assets and liabilities for current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rate and tax laws used to compute the amount are those enacted or substantively enacted by the statement of financial position date. Deferred tax Deferred tax is calculated using the liability method on temporary differences at the statement of financial position date between the tax base of assets and liabilities and their carrying amount for financial reporting purposes. Deferred tax liabilities are recognized for all taxable temporary differences, except where the deferred tax liability arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting, nor taxable profit or loss. Deferred tax assets are recognized for all temporary differences including unused tax credits and tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences can be utilized, except where the deferred tax assets relate to deductible temporary differences from initial recognition of an asset or liability in a transaction that is not a business combination, and, at the time of the transaction, affects neither accounting, nor taxable profit or loss. It is probable that taxable profit will be available when there are sufficient taxable temporary differences relating to the same tax authority and the same taxable entity which are expected to reverse in the same period as the expected reversal of the deductible temporary difference. The carrying amount of deferred tax assets is reviewed at each statement of financial position date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to utilize them. Unrecognized deferred tax assets are reassessed at each statement of financial position date and are recognized to the extent it is probable that future taxable profit will enable the asset to be recovered. Deferred tax assets and liabilities are measured at the tax rate expected to apply in the year when the assets are realized or liabilities settled, based on tax rates and tax laws that have been enacted or substantively enacted at the statement of financial position date. Deferred tax assets and deferred tax liabilities are offset where legally enforceable set off rights exist and the deferred taxes relate to the same taxable entity and the same taxation authority.

At December 31, 2018, Millicom had $584 million of unremitted earnings of Millicom operating subsidiaries for which no deferred tax liabilities were recognized (2017: $842 million; 2016: $873 million). Except for intragroup dividends to be paid out of 2018 profits in 2019 for which deferred tax of $34 million (2017: $32 million; 2016 $32 million) has been provided, it is anticipated that intragroup dividends paid in future periods will be made out of profits of future periods.
