List Of Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies The principal accounting policies applied in the preparation of these financial statements are set out below. These accounting policies have been consistently applied to all the years presented, unless otherwise stated. 2.1 Basis of preparation The annual financial statements of the Group for the year ended March 31, 2018 have been prepared in accordance with: • International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”); • IFRS Interpretations Committee (“IFRIC”) interpretations applicable to companies reporting under IFRS; • SAICA Financial Reporting guides as issued by the Accounting Practices Committee; • Financial Pronouncements as issued by the Financial Reporting Standards Council (“FRSC”); • the requirements of the South African Companies Act, No. 71 of 2008; and • the JSE Listings Requirements. The financial statements have been prepared in thousands of Rand (R’000) under the historical cost convention except for certain financial instruments that have been measured at fair value. The preparation of financial statements in accordance with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions or estimates are significant to the financial statements, are disclosed in note 4. 2.1.1 Changes in accounting policy and disclosures 2.1.1.1 New standards, amendments and interpretations adopted by the Group Standards, amendments and interpretations which are effective for the financial year beginning on or after April 1, 2017 did not have a material impact on the Group. 2.1.1.2 New standards, amendments and interpretations not yet effective Certain new accounting standards and interpretations have been published that are not mandatory for the March 31, 2018 reporting period and have not been early adopted by the Group in fiscal 2018. The effect of adopting IFRS 9, IFRS 15 and IFRS 16 is set out below. Management is in the final stages of its project to adopt IFRS 9, IFRS 15 and IFRS 16 and as such the figures mentioned below represent our current expectations of the impact from these standards. Standards and amendments Executive summary IFRS 9 Financial Instruments (“IFRS 9”) IFRS 9 addresses classification and measurement of financial assets and replaces the multiple classification and measurement models in IAS 39 Financial Instruments: Recognition and Measurement with a single model that has only two classification categories: amortized cost and fair value. IFRS 9 also introduces a new impairment model and aligns hedge accounting more closely with an entity’s risk management. The standard is effective for the Group from April 1, 2018. The most relevant change to the Group is the requirement to use an expected loss model instead of the incurred loss model, which is currently being used, when assessing the recoverability of trade and other receivables. Based on the expected loss model contained in IFRS 9, the expected increase in the provision for doubtful debts at April 1, 2018 is between R2.0 million and R4.0 million. IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) IFRS 15 replaces IAS 18 Revenue and IAS 11 Construction Contracts . It is a single, comprehensive revenue recognition model for all contracts with customers and has the objective of achieving greater consistency in the recognition and presentation of revenue. In terms of the new standard, revenue is recognized based on the satisfaction of performance obligations, which occurs when control of goods or services transfers to a customer. The revenue standard is effective for annual periods beginning on or after January 1, 2018 and therefore is applicable for the Group from April 1, 2018. The standard permits a modified retrospective cumulative catch-up approach for the adoption, which the Group has decided to apply. Under this approach the Group will recognize transitional adjustments in retained earnings on the date of initial application (i.e. April 1, 2018), without restating the comparative period. Under the practical expedient, the new requirements only need to be applied to contracts that are not completed as of April 1, 2018. The Group has assessed the impact of applying IFRS 15 on its financial statements and has identified the following areas that will be affected: Costs incurred in obtaining a contract : Commissions incurred to acquire contracts need to be capitalized and amortized, unless the amortization period is 12 months or less. Currently, the Group expenses commissions. Under IFRS 15, the amortization expense reflects the settlement of the related performance obligations, which, depending on the specific contract, may include hardware, installation, training and/or service. To the extent commission capitalized is commensurate, the commission attributable to service will be amortized over the minimum contractual period or, if shorter, the expected life of the contract. To the extent it is not commensurate, the commission capitalized that is attributable to service will be amortized over the expected life of the contract. The expected impact on the Group at April 1, 2018 is as follows: — Capitalized commission asset with a net book value of between R43.0 million and R48.0 million; and — Additional recurring commission liability of between R6.0 million and R8.0 million. Recurring commission is commission which is payable for each month the customer remains with the Group. Since the commission relates to acquiring a customer contract, as part of the adoption of IFRS 15, a recurring commission liability will be recognized at the date on which the contract is acquired. The measurement will reflect the total commission payable over the minimum contractual period or, if shorter, the expected life of the contract, together with the effect of the time value of money, where significant. Under current accounting the recurring commissions are accrued for on a monthly basis. Amortization expense of external commissions capitalized under IFRS 15 will be recognized in cost of sales, while that of internal commissions will be recognized in sales and marketing costs. Commissions not capitalized under the 12-month practical expedient will also be classified in the same manner. This is in line with the current income statement presentation of the commission expense. The impact of IFRS 15 on both cost of sales and sales and marketing costs for fiscal 2019 is not expected to be material based on current forecasts. Standards and amendments Executive summary IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) Significant financing: In respect of contracts for which the Group receives payment more than 12 months in advance, interest expense will need to be accrued on the income received in advance liability. This will result in the revenue being measured at a higher amount when it is recognized, compared to current accounting. At April 1, 2018, it is expected that the income received in advance liability (which will be disclosed as ‘liabilities related to contracts with customers’) will be between R1.0 million and R3.0 million higher than the balance at March 31, 2018. Fixed escalations: Fixed escalations will need to be spread evenly over the contract period resulting in the related revenue being different to what is actually billed. In the earlier part of the contract, revenue will be higher than the amount billed, while in the latter part it will be lower. Currently, the Group recognizes the increase in revenue due to fixed escalations only once the escalations are effective. A contract asset of between R1.0 million and R2.0 million is expected to be recognized on April 1, 2018, reflecting the amount by which revenue should have been higher under IFRS 15 in periods prior to March 31, 2018 as a result of straight-lining the fixed escalations. IFRS 16 Leases (“IFRS 16”) IFRS 16 replaces IAS 17 Leases and addresses the accounting and disclosures for leases. IFRS 16 applies to annual reporting periods beginning on or after January 1, 2019, but can be early adopted. Given that the Group will be applying IFRS 15 from April 1, 2018, the Group decided to also adopt IFRS 16 from this date. The Group has chosen to apply the ‘simplified approach’ on adoption of IFRS 16 that includes certain relief related to the measurement of the right-of-use asset and the lease liability at April 1, 2018, rather than full retrospective application. Furthermore, the ‘simplified approach’ does not require a restatement of comparatives. The Group leases land and buildings, office equipment and vehicles which are currently treated as operating leases. The expected impact on the Group at April 1, 2018 is as follows: — Right-of-use asset with a net book value of between R29.0 million and R32.0 million; and — Lease liability (net of accruals/prepayments already recognized) of between R31.0 million and R35.0 million. Summary of the expected impact at April 1, 2018 of adopting IFRS 9, IFRS 15 and IFRS 16: IFRS 9 assets (R2.0 million to R4.0 million) IFRS 15 assets R44.0 million to R50.0 million IFRS 16 assets R29.0 million to R32.0 million Total assets R71.0 million to R78.0 million IFRS 15 liabilities R7.0 million to R11.0 million IFRS 16 liabilities R31.0 million to R35.0 million Deferred tax liabilities R6.0 million to R10.0 million Total liabilities R44.0 million to R56.0 million Net increase in retained income R22.0 million to R27.0 million Summary of the expected impact on fiscal 2019 results of adopting IFRS 9, IFRS 15 & IFRS 16: The impact on profit after tax for fiscal 2019 is not expected to be material. 2.2 Consolidation (a) Subsidiaries Subsidiaries are all entities (including structured entities) over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the relevant activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. Inter-company transactions, balances and unrealized gains on transactions between Group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Group. Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated income statement, statement of comprehensive income, statement of changes in equity and statement of financial position, respectively. (b) Business combinations The acquisition method of accounting is used to account for all business combinations, regardless of whether equity instruments or other assets are acquired. The consideration transferred for the acquisition of a subsidiary comprises the: • fair values of the assets transferred; • liabilities incurred to the former owners of the acquired business; • equity interests issued by the Group; • fair value of any asset or liability resulting from a contingent consideration arrangement; and • fair value of any pre-existing equity interest in the subsidiary. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are, with limited exceptions, measured initially at their fair values at the acquisition date. The Group recognizes any non-controlling interest in the acquired entity on an acquisition-by-acquisition basis either at fair value or at the non-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. Acquisition-related costs are expensed as incurred, except if related to the issue of equity securities, in which case these costs are also included in equity. The excess of the: • consideration transferred; • amount of any non-controlling interest in the acquired entity; and • acquisition-date fair value of any previous equity interest in the acquired entity over the fair value of the net identifiable assets acquired is recorded as goodwill. If those amounts are less than the fair value of the net identifiable assets of the subsidiary acquired, the difference is recognized directly in the income statement as a bargain purchase gain. Where settlement of any part of cash consideration is deferred, the amounts payable in the future are discounted to their present value as at the date of acquisition. The discount rate used is the entity’s incremental borrowing rate, being the rate at which a similar borrowing could be obtained from an independent financier under comparable terms and conditions. Unwinding of the interest element is recognized in the income statement. Contingent consideration is measured at fair value on acquisition date and classified either as equity or a financial liability. Amounts classified as a financial liability are subsequently remeasured to fair value with changes in fair value recognized in the income statement. (c) Changes in ownership interests in subsidiaries without a change of control The Group treats transactions with non-controlling interests that do not result in a loss of control as transactions with equity owners of the Group, that is, transactions with the owners in their capacity as owners. For purchases from non-controlling interests, the difference between the fair value of any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity. 2.3 Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (“CODM”). The CODM, who is responsible for allocating resources and assessing performance of the operating segments, has been identified collectively as the executive committee and the Chief Executive Officer who make strategic decisions. S ales between segments are carried out at cost plus a margin. 2.4 Foreign currency translation (a) Functional and presentation currency Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in South African Rand (“R”), which is the Group’s presentation currency. (b) Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year-end exchange rates are recognized in the income statement. Foreign exchange gains/(losses) are classified as “Finance income/(cost) — net”. Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation differences on non-monetary financial assets and liabilities such as equities classified as available-for-sale, are included in other comprehensive income. (c) Group companies The results and financial position of foreign operations (none of which has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows: (i) Assets and liabilities for each statement of financial position presented are translated at the closing rate at the date of that statement of financial position; (ii) Income and expenses for each income statement presented are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions); (iii) All resulting exchange differences are recognized in other comprehensive income; and (iv) Equity items are measured at historical cost at the time of recording, translated at the rate on the date of the recording and are not retranslated to closing rates at reporting dates. On consolidation, exchange differences arising from the translation of net investments in foreign operations are recognized in other comprehensive income. When a foreign operation is fully disposed of or sold (i.e., control is lost), exchange differences that were recorded in equity are recognized in the income statement as part of the gain or loss on sale. A repayment/capitalization of a net investment loan therefore does not result in any exchange differences being transferred from equity to the income statement unless it is part of a transaction resulting in a loss of control. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing rate. Exchange differences are recognized in other comprehensive income. 2.5 Property, plant and equipment Property, plant and equipment is stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes all expenditure directly attributable to the acquisition of the items. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of any component accounted for as a separate asset is derecognized when replaced. Repairs and maintenance are charged to the income statement in the reporting period in which they are incurred. The cost of in-vehicle devices installed in vehicles (including installation and shipping costs) as well as the cost of uninstalled in-vehicle devices, is capitalized as property, plant and equipment. The Group depreciates installed in-vehicle devices on a straight-line basis over their expected useful lives, commencing upon installation, whereas uninstalled in-vehicle devices are not depreciated until installed. The related depreciation expense is recorded as part of cost of sales in the income statement. Land is not depreciated. Depreciation on other assets is calculated using the straight-line method to reduce their cost to their residual values over their estimated useful life, as follows: Property: Buildings 50 years Plant and equipment 3 — 20 years Motor vehicles 3 — 7 years Other: Furniture, fittings and equipment 1 — 10 years Computer and radio equipment 2 — 6 years In-vehicle devices installed 1 — 5 years The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period. An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount (note 2.7). Gains and losses on disposal of an asset are determined by comparing the proceeds with the carrying amount and are recognized within “Other income/(expenses) — net” in the income statement. 2.6 Intangible assets (a) Goodwill Goodwill arises on the acquisition of businesses and represents the excess of consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the acquirer’s interest in the net fair value of the net assets acquired. Goodwill on acquisition of businesses is included in intangible assets. Gains and losses on the disposal of an entity include the carrying amount of the goodwill relating to the entity sold. Goodwill is not amortized but is tested annually for impairment, or more frequently if events or changes in circumstances indicate a potential impairment, and is carried at cost less accumulated impairment losses. Goodwill is allocated to cash-generating units (“CGUs”) for the purpose of impairment testing. The allocation is made to those CGUs or groups of CGUs that are expected to benefit from the business combination in which the goodwill arose. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal management purposes. Goodwill is monitored at the operating segment level. The carrying amount of the CGU containing the goodwill is compared to the recoverable amount, which is the higher of value-in-use and the fair value less costs to sell. Impairment losses recognized as an expense in relation to goodwill are not subsequently reversed. (b) Patents and trademarks Separately acquired patents and trademarks are shown at historical cost. Patents and trademarks acquired in a business combination are recognized at fair value at the acquisition date. Patents and trademarks have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. Amortization is calculated using the straight-line method to allocate the cost of patents and trademarks over their estimated useful lives ( three to 20 years ). (c) Customer relationships Customer relationships acquired in a business combination are recognized at fair value at the acquisition date. Customer relationships have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. Amortization is calculated over the expected useful life of the customer relationship ( two to 15.5 years ) and reflects the pattern in which future economic benefits of the customer relationship are expected to be consumed. The useful life principally reflects management’s view of the average economic life of the customer base and is assessed by reference to factors such as customer churn rates. (d) Computer software, technology, in-house software and product development costs Acquired computer software licenses are capitalized on the basis of costs incurred to acquire and bring the software into use. The acquired computer software licenses have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. These costs are amortized over their estimated useful lives ( two to five years ). In-house software and product development costs that are directly attributable to the design, testing and development of identifiable and unique software and products, controlled by the Group, are recognized as intangible assets when the following criteria are met: • It is technically feasible to complete the software or product so that it will be available for use; • Management intends to complete the software or product and use or sell it; • There is an ability to use or sell the software or product; • It can be demonstrated how the software or product will generate probable future economic benefits; • Adequate technical, financial and other resources to complete the development and use or sell the software or product are available; and • The expenditure attributable to the software or product during its development can be reliably measured. Directly attributable costs that are capitalized as part of the intangible assets include software and product development employee costs and an appropriate portion of relevant overheads. Other development expenditures that do not meet the criteria are recognized as an expense as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period if the criteria are subsequently met. Costs, including annual licenses, associated with maintaining computer software programs are recognized as an expense as incurred. Technology, in-house software and product development costs are capitalized on the basis of costs incurred to acquire and bring them into use. The recognized assets have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. In addition, they are amortized over their estimated useful lives ( one to 15 years ). 2.7 Impairment of non-financial assets Assets that have an indefinite useful life, goodwill and intangible assets that are not ready to use are not subject to amortization but are tested annually for impairment or more frequently if events or changes in circumstances indicate that they might be impaired. Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less cost to sell, and value-in-use. In assessing the value-in-use, the estimated future cash flows are discounted to their present value using the pre-tax discount rate that reflects current market assessments on the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (CGUs, i.e. operating segments). Non-financial assets other than goodwill that have suffered impairment are reviewed for possible reversal of the impairment at each reporting date. 2.8 Financial assets 2.8.1 Classification The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition. Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for those with maturities greater than 12 months after the end of the reporting period, which are classified as non-current assets. The Group’s loans and receivables comprise trade and other receivables, finance lease receivables, restricted cash and cash and cash equivalents in the statement of financial position. 2.8.2 Recognition and derecognition Regular way purchases and sales of financial assets are recognized on the trade date (the date on which the Group commits to purchase or sell the asset). Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. 2.8.3 Measurement Financial assets are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Loans and receivables Loans and receivables are subsequently carried at amortized cost using the effective interest method, less any impairment losses. 2.8.4 Impairment of financial assets The Group assesses, at the end of each reporting period, whether there is objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated. Loans and receivables Evidence of impairment may include indications that the debtors or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization and where observable data indicates that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults. For the loans and receivables category, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred), discounted at the financial asset’s original effective interest rate. The asset’s carrying amount is reduced and the amount of the loss is recognized in the income statement. If a loan has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the reversal of the previously recognized impairment loss is recognized in the income statement. 2.9 Fair value Fair value is determined in accordance with IFRS 13 Fair Value Measurement and is categorized as follows: • Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices); and • Level 3: Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs). The carrying amounts for cash and cash equivalents, restricted cash, trade and other receivables (excluding pre-payments), trade and other payables (excluding leave pay) and the current portion of leases approximate fair value due to their short-term nature. 2.10 Offsetting financial instruments Financial assets and liabilities are offset and the net amount reported in the statement of financial position when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis, or realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the Group or the counterparty. 2.11 Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined on a first-in, first-out (“FIFO”), actual cost or weighted average cost basis, depending on the nature of the Group entity in which it is held. The cost of finished goods includes the cost of manufacturing as charged by third parties. It excludes borrowing costs. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs necessary to make the sale. 2.12 Trade receivables Trade receivables are amounts due from customers for goods sold or services performed in the ordinary course of business. If collection is expected in one year or less they are classified as current assets. If not, they are presented as non-current assets. Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less provision for impairment. 2.13 Net cash and cash equivalents Net cash and cash equivalents included in the statement of cash flows include cash on hand, deposits held on call with banks and bank overdrafts; all of which are available for use by the Group and have an original maturity of less than three months. Bank overdrafts are included within current liabilities on the statement of financial position. 2.14 Restricted cash Restricted cash includes short-term deposits and amounts held that are not highly liquid and is accounted for as loans and receivables. 2.15 Stated capital Ordinary shares are classified as equity. Incremental external costs directly attributable to the issue of new shares or the exercise of share options are shown in equity as a deduction, net of ta

List Of Accounting Policies [Abstract]
Financial risk management	Financial risk management 3.1 Financial risk factors The Group’s activities expose it to a variety of financial risks: market risk (including foreign exchange risk, interest rate risk, and price risk), credit risk, and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets as it relates to financial risks and seeks to minimize potential adverse effects on the Group’s financial performance. Risk management is carried out under policies approved by the Board of Directors. The Board has provided approved formal policies covering specific areas, such as foreign exchange risk as well as cash management and banking facilities. (a) Market risk (i) Foreign exchange risk The Group operates internationally and is exposed to foreign exchange risk arising from various currencies, primarily with respect to the United States Dollar, the South African Rand, the Euro, the Australian Dollar, the Brazilian Real and the British Pound. Foreign exchange risk arises when future commercial transactions or recognized assets and liabilities and net investments in foreign operations are denominated in a currency that is not the entity’s functional currency. The Group has implemented a foreign currency hedging policy to limit the Group’s exposure to fluctuations in foreign currencies. The foreign currency policy reduces exchange rate risk on certain recognized assets and liabilities based on economic hedging principles as opposed to using derivative financial instruments. The Group has certain investments in foreign operations, whose net assets are exposed to foreign currency translation risk. Currency exposure arising from the assets of the Group’s foreign operations is reduced as a result of assets and liabilities being denominated in the same foreign currencies. As a result of our cash reserves being held in multiple currencies, the Group has significant foreign currency exposure. A financial risk sensitivity analysis is presented in note 36. (ii) Interest rate risk Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Group’s cash flow interest rate risk arises from restricted cash, cash and cash equivalents and the bank overdraft. Bank overdrafts issued at variable rates expose the Group to cash flow interest rate risk, which is partly offset by financial assets held at variable rates (i.e. cash and cash equivalents and restricted cash). At March 31, 2018 and 2017 the Group had no interest-bearing borrowings. The Group is not exposed to fair value interest rate risk as the Group does not have any fixed rate interest-bearing financial instruments carried at fair value. Interest rates are constantly monitored and appropriate steps are taken to ensure that the Group’s exposure to interest rate fluctuations is limited. This includes obtaining approval from the Board for all changes to and new borrowing facilities entered into. Refer to note 36 for an interest rate risk sensitivity analysis. (iii) Price risk Currently the Group does not have significant price risk. The Group is not exposed to commodity price risk. (b) Credit risk Credit risk is the risk that a counterparty to a financial instrument will fail to discharge an obligation and cause the Group to incur a financial loss. Credit risk arises from restricted cash, cash and cash equivalents as well as credit exposures to customers. The maximum exposure to credit risk is represented by the carrying amount of each financial asset in the statement of financial position, net of impairment losses where relevant. Credit risk relating to accounts receivable balances is managed by each local entity which is responsible for managing and analyzing the credit risk for each of their new clients before standard payment and delivery terms and conditions are offered. The Group has a policy in place governing the allowance for credit losses. Cash investments are only placed with reputable financial institutions rated BB and above (note 12). All changes in or new banking arrangements entered into are in line with the Board’s approval framework. Refer to note 10 for further disclosure on credit risk. (c) Liquidity risk Liquidity risk is the risk that there will be insufficient funds available to settle obligations when they are due. The Group has limited liquidity risk due to surplus cash balances and the recurring nature of its income, which generates strong cash inflows. The level of cash balances in the Group is monitored weekly and cash generated from operations is reviewed against planned cash flows on a monthly basis. In addition, working capital reviews are performed monthly. Surplus cash is invested in interest-bearing current accounts and time deposits that are expected to readily generate cash inflows for managing liquidity risk. In addition, the Group maintains headroom on its undrawn borrowing facilities to ensure that the Group does not breach borrowing limits on its borrowing facilities. Refer to note 37 for further disclosure on liquidity risk. 3.2 Capital risk management The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern while enhancing the returns for shareholders and ensuring benefits for other stakeholders. The Board of Directors monitors capital by reviewing the net cash position. The Company currently has no long-term borrowings and none of its overdraft facilities, as set out in note 15, were subject to any financial covenants during fiscal 2018 and fiscal 2017. In order to maintain the capital structure, the Group may return capital to shareholders, issue new shares or sell assets to reduce debt, where applicable.

List Of Accounting Policies [Abstract]
Critical accounting estimates and judgements	Critical accounting estimates and judgements Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have significant risk of causing a material adjustment to the carrying amounts of assets and liabilities during fiscal 2018 are outlined below: (a) Warranty claims The Group generally offers warranties on its hardware units. Management estimates the related provision for future warranty claims based on historical warranty claim information, as well as recent trends that might suggest that past cost information may differ from future claims. (b) Maintenance provision The Group, in some instances, offers maintenance services as part of its revenue contracts. Management estimates the related provision for maintenance costs per vehicle when the obligation to repair occurs. (c) Current and deferred income taxes The Group is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the worldwide provision for income taxes. Where applicable tax legislation is subject to interpretation, management makes assessments, based on expert tax advice, of the relevant tax that is likely to be paid and provides accordingly. When the final outcome is determined and there is a difference, this is recognized in the period in which the final outcome is determined. Determining how much tax to recognize when an uncertain tax position exists requires judgement. The Group applies the measurement principle in IAS 12 Income Taxes , when measuring the amount of tax to recognize related to an uncertain tax position. Therefore, the Group measures uncertain tax positions based on a weighted average estimate, taking into account all of the tax uncertainties related to the tax position taken. The Company's interests in subsidiaries include certain loans denominated in foreign currencies which are repayable by agreement of both parties. Realization of such loans will result in taxable foreign exchange differences in accordance with prevailing legislation in South Africa. Although the Company controls the timing of the reversal of these temporary differences, given the volatility of the South African Rand and based on the Group's current assessment, it is not considered probable that the temporary difference relating to a loan between the Company and a South Africa subsidiary will not reverse in the foreseeable future. Hence, a deferred tax liability has been recognized in respect of these temporary differences (note 18). The Group applies judgement when recognizing deferred tax assets in respect of tax losses. Deferred tax assets in respect of tax losses are recognized for the carry forward of unused tax losses to the extent that it is probable that future taxable profit will be available against which the unused tax losses can be utilized. In determining the level of future taxable profit that will be available the Group considers both an entity's historical profitability and estimates of future profitability and recognizes deferred tax for the whole or the part of the temporary difference that is more likely than not to be recovered. Where an entity has incurred historical losses, deferred tax assets are only recognized when the particular entity has shown a reasonable period of starting to return to profitability. (d) Impairment estimates The Group tests annually whether goodwill has suffered any impairment in accordance with the accounting policy stated in note 2.7. Other assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. For the purposes of assessing impairment, assets are grouped into CGUs at the lowest levels for which there are separately identifiable cash flows. The recoverable amount is based on the CGU’s value-in-use. These calculations require the use of estimates (see notes 6 and 7). (e) Customer relationships T he useful life applied principally reflects management’s view of the average economic life of the customer base and is assessed by reference to factors such as customer churn rates. An increase in churn rates may lead to a reduction in the estimated useful life. (f) Product development cost Product development cost directly attributable to the design and testing of identifiable and unique software products controlled by the Group are recorded as intangible assets by the Group when the criteria in note 2.6 have been met. The assessment as to when these criteria have been met is subjective and capitalization has been based on management’s best judgement of facts and circumstances in existence at year-end. The useful lives of development costs capitalized are reviewed on an at least annual basis. The useful life estimates are based on historical experience with similar assets as well as anticipation of future events such as technological changes, which may impact the useful life. The residual values of product development costs are estimated to be zero. (g) Provision for impairment of trade receivables The provision for impairment of trade receivables reflects the Group’s estimates of losses arising from the failure or inability of the Group’s customers to make required payments. The provision is based on the ageing of customer accounts, customer creditworthiness and the Group’s historical write-off experience. Changes to the allowance may be required if the financial condition of the Group’s customers improves or deteriorates. An improvement in financial condition may result in lower actual write-offs. Historically, changes to the estimate of losses have not been material to the Group’s financial position and results. (h) Allocation between in-vehicle devices and inventory The allocation between in-vehicle devices and inventory reflects the Group’s estimates of how units are expected to be sold, thereby it is a significant area of judgement for the Group.

Operating Segments [Abstract]
Segment Information	Segment information Our operating segments are based on the geographical location of our Regional Sales Offices (“RSOs”) and also include our Central Services Organization (“CSO”). CSO is our central services organization that wholesales our products and services to our RSOs who, in turn, interface with our end-customers, distributors and dealers. CSO is also responsible for the development of our hardware and software platforms and provides common marketing, product management, technical and distribution support to each of our other operating segments. The chief operating decision maker (“CODM”) reviews the segment results on an integral margin basis as defined by management. The CODM, who is responsible for allocating resources and assessing performance of the operating segments, has been identified collectively as the executive committee and the Chief Executive Officer who make strategic decisions. In respect of revenue, this method of measurement entails reviewing the segmental results based on external revenue only. In respect of Adjusted EBITDA (the profit measure identified by the CODM), the margin generated by CSO, net of any unrealized intercompany profit, is allocated to the geographic region where the external revenue is recorded by our RSOs. The costs remaining in CSO relate mainly to research and development of hardware and software platforms, common marketing, product management and technical and distribution support to each of the RSOs. CSO is a reportable segment of the Group because it produces discrete financial information which is reviewed by the CODM and has the ability to generate external revenues. Each RSO's results therefore reflect the external revenue earned, as well as the Adjusted EBITDA earned (or loss incurred) by each operating segment before the remaining CSO and corporate costs allocations. Segment assets are not disclosed as segment information is not reviewed on such a basis by the CODM. The Group’s CODM assesses the performance of the operating segments based on Adjusted EBITDA. Adjusted EBITDA is defined as the profit for the period before income taxes, net finance income/(costs) including foreign exchange gains/(losses), depreciation of property, plant and equipment including capitalized customer in-vehicle devices, amortization of intangible assets including capitalized in-house development costs and intangible assets identified as part of a business combination, share-based compensation costs, transaction costs arising from the acquisition of a business or investigating strategic alternatives, restructuring costs, profits/(losses) on the disposal or impairments of assets or subsidiaries, insurance reimbursements relating to impaired assets and certain litigation costs.

During fiscal 2017, a reversal of impairment of R0.8 million in respect of in-vehicle devices which were impaired in fiscal 2016 was recognized in profit or loss by the Brazil segment. The improvement in trading conditions in the Brazil segment resulted in the reassessment of its recoverable amount in fiscal 2017. I n fiscal 2017 the assessment indicated that the recoverable amount was higher than its carrying value which led to the aforementioned impairment reversal. Assets classified as held for sale The assets classified as held for sale relate to the property held by the CSO segment. No impairment loss was recognized on reclassification of the property as held for sale as the fair value (estimated based on the recent market prices of similar properties in similar locations) less costs to sell is higher than the carrying amount.

In fiscal 2018, staff costs of R46.4 million (2017: R54.6 million , 2016: R45.2 million ) have been capitalized to product development costs. In fiscal 2018, no staff costs were capitalized to in-house software (2017: R1.6 million , 2016: R1.3 million ). Additions of R94.6 million were made during fiscal 2018. In addition, R1.9 million relating to capitalized development costs and R3.1 million related to computer software, technology, in-house software and other intangibles were paid in the current fiscal year which were accrued and accounted for as non-cash additions in 2017. Additions of R119.4 million made during 2017 included non-cash additions of R5.0 million as described above. R0.9 million relating to capitalized development costs were paid in fiscal 2017 which were accrued and accounted for as non-cash additions in 2016. Amortization expense of R44.1 million (2017: R30.1 million , 2016: R24.9 million ) has been charged to cost of sales. The remainder has been included in administration and other charges in the income statement. During fiscal 2018, impairments to capitalized product development costs of R0.4 million within the CSO segment and R2.3 million within the Africa segment were recognized in profit or loss. During fiscal 2017, impairments to capitalized product development costs of R0.5 million within the CSO segment and R2.6 million within the Africa segment were recognized in profit or loss. The impairment losses have been included in administration and other charges in the income statement. Included in product development costs is product development assets in progress with a net book amount of R32.1 million (2017: R51.1 million , 2016: R43.6 million ). Computer software, technology, in-house software and other included no internally generated in-house software in progress (2017: R42.8 million , 2016: R18.3 million ). Change in estimate of useful lives of product development costs capitalized During fiscal 2018, the CSO segment reassessed the useful lives of certain projects where, on average, the useful lives were increased from 5.0 years to 6.5 years . The reassessment of the useful lives resulted in a R4.5 million reduction in the product development amortization expense relative to what it would have been in fiscal 2018 had the change not occurred. The a mortization reduction expected to be charged to the income statement over the future fiscal years is as follows: Year ended March 31, 2019 2020 2021 2022 2023 2024 2025 2026 2027 2028 R’000 1,694 611 748 457 334 303 158 106 106 27 Impairment tests for goodwill Goodwill is allocated to the Group’s CGUs identified within its operating segments. It should be noted that, as disclosed in note 5, while CSO is reported as a reportable segment excluding any inter-company revenue and related costs, it remains a CGU, as there remains an active market for the output produced by CSO. The impairment tests for goodwill have been performed on the same basis as the previous financial years. A summary of the goodwill at operating segment level is presented below: March 31, 2017 R’000 Foreign currency translation differences R'000 March 31, 2018 R’000 Central Services Organization 103,119 — 103,119 Europe 109,610 (986 ) 108,624 Middle East and Australasia 53,131 (6,280 ) 46,851 Africa 353,050 — 353,050 Total 618,910 (7,266 ) 611,644 The recoverable amounts of all CGUs are determined based on value-in-use calculations, which use pre-tax cash flow projections based on approved financial budgets covering a three to five -year period. A five -year period was used to ensure that in respect of the Europe and Middle East and Australasia segments, stable cash flows are used for purposes of calculating terminal values included in the value-in-use calculations. These cash flows are based on the current market conditions and near-term expectations. The key assumptions used for the value-in-use calculations are as follows : 2018 Central Services Organization Africa Europe Middle Discount rate – pre-tax discount rate applied to the cash flow projections (%) 17.1 17.3 9.2 13.3 Growth rate – growth rate used to extrapolate cash flow beyond the budget period (%) 5.4 5.4 2.2 2.9 2017 Central Services Organization Africa Europe Middle Discount rate – pre-tax discount rate applied to the cash flow projections (%) 17.6 18.6 9.8 16.0 Growth rate – growth rate used to extrapolate cash flow beyond the budget period (%) 5.5 5.5 2.3 2.5 The discount rates were calculated using the capital asset pricing model. These rates reflect specific risks relating to the relevant CGUs. The growth rate has been determined based on the expected long-term inflation outlook . Goodwill sensitivity Given the significant headroom that exists in the CGUs, management believes that a reasonable change in assumptions would not result in any goodwill impairments.

The terms of the leases varied between 24 and 36 months and the leases were denominated in Euro. The unguaranteed residual values of the assets leased under finance lease were considered negligible. At March 31, 2017 the finance lease receivables were neither past due nor impaired and were fully settled at March 31, 2018. In determining the recoverability of the finance lease receivables, the Group considered any change in the credit quality of the finance lease receivable from the date the leases were initially entered into until the end of the fiscal 2017 reporting year.

In determining the recoverability of a receivable, the Group considers any change in the credit quality of the receivable from the date credit was initially granted until the end of the reporting year. Amounts provided for are generally written off when there is no expectation of recovering the amount. A single sundry debtor of R4.6 million which was past due and fully impaired in fiscal 2017 was recovered in fiscal 2018. Trade receivables of R17.9 million (2017: R11.1 million ) are pledged as security for the Group’s overdraft facilities (note 12, 15). The maximum exposure to credit risk at the reporting date is the carrying value of each class of receivable mentioned above. Other than 11% of the gross receivable balance relating to two debtors at the end of fiscal 2018 (2017: 11% of the gross receivable balance relating to two debtors), the Group has no significant concentration of credit risk, due to its spread of customers across various operations and geographical locations. The Group does not hold any collateral as security.

All issued shares are fully paid up and carry one vote per share and the right to dividends. There were no changes to the authorized number of ordinary shares during the current or prior financial year. In terms of a special resolution approved in fiscal 2014 a new class of no par value shares, consisting of 100 million preference shares, was created. No preference shares have been issued to date. Share repurchases Fiscal 2018 On May 23, 2017, the MiX Telematics Board of Directors approved a share repurchase program of up to R270 million under which the Company may repurchase its ordinary shares, including American Depositary Shares (“ADSs”). The Company may repurchase its shares from time to time at its discretion through open market transactions and block trades, based on ongoing assessments of the capital needs of the Company, the market price of its securities and general market conditions. This share repurchase program may be discontinued at any time by the Board of Directors, and the Company has no obligation to repurchase any amount of its securities under the program. The repurchase program will be funded out of existing cash resources.

Fiscal 2017 On April 29, 2016, the Company entered into an agreement (the “share repurchase agreement”) with Imperial Holdings Limited (“Imperial Holdings”) and Imperial Corporate Services Proprietary Limited (“Imperial Corporate Services”), a wholly owned subsidiary of Imperial Holdings, to repurchase all 200,828,260 of the Company’s shares held by Imperial Corporate Services (the “repurchase shares”) at R2.36 per repurchase share, for an aggregate repurchase consideration of R474.0 million (the “repurchase”). At the general meeting held on August 1, 2016, shareholders of the Company approved the repurchase in terms of the JSE Listings Requirements and the South African Companies Act, No. 71 of 2008, at which point the transaction was accounted for in terms of IFRS. The repurchase was implemented on August 29, 2016. Subsequent to the repurchase, the shares were delisted and now form part of the authorized unissued share capital of the Company. In fiscal 2017, the financial effect of the transaction was as follows: R’000 Aggregate repurchase consideration 473,955 Impact of discounting related to the fiscal 2017 share repurchase transaction (note 25) (3,222 ) Transaction costs capitalized 2,949 Total share repurchase costs 473,682 Equity incentive plans The Group has issued share incentives under two equity incentive plans, the TeliMatrix Group Executive Incentive Scheme and the MiX Telematics Long-Term Incentive Plan (“LTIP”), to directors and certain key employees within the Group. With the introduction of the LTIP, which was approved by shareholders in terms of an ordinary resolution during 2014, no further awards will be made in terms of the TeliMatrix Group Limited Executive Incentive Scheme going forward. The LTIP is now being used to issue share incentives to employees and executive members within the Group. The LTIP provides for three types of grants to be issued, namely performance shares, retention shares or share appreciation rights (“SARs”). To date only SARs have been issued. The table below indicates the total number of awards under the LTIP which are available for issue: Number of awards Reconciliation of number of awards available for issue under the LTIP Maximum number of awards that may be issued during the life of the LTIP 120,000,000 Issued in fiscal 2015 (2,900,000 ) Number of awards available for issue as at March 31, 2015 117,100,000 Issued in fiscal 2016 (11,835,000 ) Number of awards available for issue as at March 31, 2016 105,265,000 Issued in fiscal 2017 (13,950,000 ) Number of awards available for issue as at March 31, 2017 91,315,000 Issued in fiscal 2018 (10,000,000 ) Number of awards available for issue as at March 31, 2018 81,315,000 Both equity incentive plans are discussed in further detail in the sections that follow. Share options under the TeliMatrix Group Executive Incentive Scheme Share options have been granted to directors and certain key employees within the Group. The exercise price of the options granted is equal to the weighted average market value of ordinary shares for the 20 days preceding the date of the grant. The options vest in tranches of 25% per annum, commencing on the second anniversary of the grant date and expire 6 years after the grant date. In addition to these vesting periods, the vesting of the share options granted are conditional on certain performance conditions being met, namely the share price on the associated measurement date being in excess of the target, after being reduced by the aggregate amount of dividends paid, or an annual total shareholder return in excess of 10% and 5% , taking into account any dividends paid during the vesting period, being achieved. The Group has no legal or constructive obligation to repurchase or settle the options in cash. Movements in the total number of share options outstanding and their related weighted average exercise prices are as follows: Weighted average exercise price 2018 cents per share Number of options 2018 000s Weighted Number of Outstanding at the beginning of the year 266 14,613 235 28,913 Exercised 195 (5,513 ) 138 (5,125 ) Forfeited — — 312 (5,875 ) Expired — — 112 (3,300 ) Outstanding at the end of the year 309 9,100 266 14,613 Exercisable at the end of the year 285 7,350 217 8,825 The weighted average remaining contractual life on share options outstanding at year-end is 1.31 years (2017: 1.87 years ). Options exercised in 2018 resulted in 5,512,500 shares (2017: 5,125,000 shares) being issued at a weighted average exercise price of 195 cents per share (2017: 138 cents per share). The related weighted average share price at the time of exercise was 608 cents per share (2017: 307 cents per share). Refer to note 23 for the total expense recognized in fiscal year 2018 in respect of equity-settled instruments granted to employees and directors.

Share appreciation rights Under the LTIP, SARs may be issued to certain directors and key employees. The award price of the SARs granted is equal to the closing market value of ordinary shares on the day preceding the date of the grant. The SARs granted vest in tranches of 25% per annum, commencing on the second anniversary of the grant date and expire six years after the grant date. In addition to these vesting periods, the vesting of the SARs granted are conditional on a performance condition of an annual total shareholder return in excess of 10% , taking into account any dividends paid during the vesting period, being achieved. Upon exercise of the SARs by participants, the Group will settle the value of the difference between the award and grant price by delivering shares, alternatively as a fall back provision only, by settling the value in cash. Movements in the total number of SARs outstanding and their related weighted average award prices are as follows: Weighted Number of 000s Weighted Number of 000s Outstanding at the beginning of the year 309 20,810 311 14,435 Granted on May 30, 2016 — — 294 9,950 Granted on November 24, 2016 — — 328 4,000 Granted on May 30, 2017 346 10,000 — — Exercised 310 (1,709 ) — — Forfeited 314 (1,062 ) 303 (7,575 ) Outstanding at the end of the year 322 28,039 309 20,810 Exercisable at the end of the year 313 1,306 305 725 The weighted average remaining contractual life on SARs outstanding at year-end is 4.38 years (2017: 4.88 ).

The related weighted average share price at the time of exercise was 464 cents per award (2017: nil ). No SARs were exercised by Group executives during fiscal 2018 and fiscal 2017. SARs outstanding at the end of the fiscal year have the following award prices: March 31, 2018 March 31, 2017 Annual shareholder return Grant date Expiry date Award price 10% December 16, 2014 December 16, 2020 305 — 725 10% August 31, 2015 August 31, 2021 313 7,764 9,160 10% May 30, 2016 May 30, 2022 294 6,525 6,925 10% November 24, 2016 November 24, 2022 328 4,000 4,000 10% May 30, 2017 May 30, 2023 346 9,750 — 28,039 20,810 The weighted average fair value of SARs granted during fiscal 2018 and fiscal 2017 was determined using a combination of the Monte Carlo Simulation option pricing model and the Binomial Tree option pricing model.

The movement in deferred tax assets and liabilities during the year, prior to taking into account the offsetting of deferred tax balances within the same tax jurisdiction, is as follows: March 31, 2017 Charged/ (credited) to the income statement (note 28) Charged/ (credited) directly to equity (note 14) Foreign March 31, 2018 R’000 R’000 R’000 R’000 R’000 Deferred tax liabilities Capital allowances for tax purposes 33,616 9,185 — 27 42,828 Intangible assets 49,807 7,279 — (2 ) 57,084 Pre-payments 2,815 68 — (26 ) 2,857 Deferred foreign currency gains 61,616 (28,318 ) 237 323 33,858 Other 1,106 105 — (324 ) 887 148,960 (11,681 ) 237 (2 ) 137,514 Deferred tax assets Revenue received in advance (14,304 ) (1,426 ) — — (15,730 ) Capital allowances for tax purposes (22,107 ) (8,503 ) — 54 (30,556 ) Provisions, accruals and lease straight-lining (28,731 ) (5,572 ) — 393 (33,910 ) Assessable losses (10,736 ) 4,713 — 131 (5,892 ) Share-based payments — (2,354 ) (5,833 ) — (8,187 ) Other (1,145 ) (155 ) — 2 (1,298 ) (77,023 ) (13,297 ) (5,833 ) 580 (95,573 ) Net deferred tax liability 71,937 (24,978 ) (5,596 ) 578 41,941 The movement in deferred tax assets and liabilities during the prior year, prior to taking into account the offsetting of deferred tax balances within the same tax jurisdiction, is as follows: March 31, 2016 Charged/ (credited) to the income statement (note 28) Charged/ (credited) directly to equity (note 14) Foreign March 31, 2017 R’000 R’000 R’000 R’000 R’000 Deferred tax liabilities Capital allowances for tax purposes 27,603 6,013 — — 33,616 Intangible assets 39,088 10,721 — (2 ) 49,807 Pre-payments 1,970 845 — — 2,815 Deferred foreign currency gains 87,878 (25,834 ) (428 ) — 61,616 Other 1,268 (163 ) — 1 1,106 157,807 (8,418 ) (428 ) (1 ) 148,960 Deferred tax assets Revenue received in advance (13,166 ) (1,138 ) — — (14,304 ) Capital allowances for tax purposes (25,609 ) 3,478 — 24 (22,107 ) Provisions, accruals and lease straight-lining (25,617 ) (3,495 ) — 381 (28,731 ) Assessable losses (1,043 ) (10,178 ) — 485 (10,736 ) Deferred foreign currency losses (487 ) — 487 — — Other (909 ) (225 ) — (11 ) (1,145 ) (66,831 ) (11,558 ) 487 879 (77,023 ) Net deferred tax liability 90,976 (19,976 ) 59 878 71,937

Share-Based Payment Arrangements [Abstract]
Share-based payment liability	Share-based payment liability March 31, 2018 March 31, 2017 Movement in share-based payment liability for the year Opening balance — — Share-based payment expense recognized during the year 1,352 1,064 Payment made in settlement of the share-based payment liability (1,353 ) (1,064 ) Foreign currency translation differences 1 — Closing balance — — MiX Brazil In June 2014, the Group entered into a quotaholders agreement with Edge, whereby Edge was granted a 5% holding in the equity interest of MiX Brazil. Prior to this quotaholders agreement Edge held a non-controlling interest in MiX Brazil of 0.0025% . Edge is a Brazilian-based investment company controlled by Luiz Munhoz, the Managing Director of MiX Brazil. The increase in the equity interests granted to Edge was in respect of services provided by Luiz Munhoz to MiX Brazil, in his role as Managing Director of MiX Brazil. In terms of the quotaholders agreement, Edge had an option to transfer its interest in MiX Brazil back to the Group at fair value. The quotaholders agreement with Edge represented a cash-settled share-based payment. In September 2017, Edge exercised the put option in the quotaholders agreement. In terms of the subsequent sale agreement MiX Investments (Proprietary) Limited acquired Edge’s 5% equity interest in MiX Brazil for R1.4 million which increased the Group's interest in MiX Brazil to 100% . As a result, the Group recognized a cash-settled share-based payment expense and liability of R1.4 million , which was subsequently settled. The non-controlling interest related to MiX Brazil of R1.5 million was also transferred to other reserves within equity (note 14). At March 31, 2017, the share-based payment liability was valued using discounted cash flow analysis. The fair value was determined by the use of cash flow projections based on approved budgets covering a five-year period. These cash flows were based on the current market conditions and near-term expectations. On a stand-alone basis at the end of fiscal 2017, the cash flow projections including debt revealed that the liability was unlikely to result in a cash outflow for the Group and as such its carrying amount was zero. The key assumptions used in the discounted cash flow analysis in fiscal 2017 were: March 31, 2017 Discount rate – pre-tax discount rate applied to the cash flow projections (%) 21.0 Growth rate – growth rate used to extrapolate cash flow beyond the budget period (%) 4.5 MiX Fleet Support Trust The cash-settled share-based payment expense incurred in 2017 was in respect of the sale of the MiX Telematics Fleet Support Trust's 51% interest in MiX Telematics Fleet Support Services Proprietary Limited to MiX Telematics Africa Proprietary Limited. The proceeds from this transaction were distributed to certain employees who are beneficiaries of the trust. The Group has no further obligations in respect of this transaction.

(2) The (non-taxable)/non-deductible foreign exchange movements arise as a result of the Group’s internal loan structures. (3) The utilization of assessed losses arises mainly in Europe, the Americas and Brazil where historical assessed losses are being utilized, as these entities are now generating taxable profits. During prior years, deferred tax assets have not been recorded for assessed losses in the Americas and Brazil. (4) The foreign tax paid relates primarily to withholding taxes on revenue earned in jurisdictions where the Group does not have a legal entity. (5) The tax incentives relate mainly to the section 11D allowance detailed below. The Group’s weighted average tax rate is 15.7% (2017: 18.1% , 2016: 36.9% ). Section 11D allowances relating to tax assets recognized MiX Telematics International Proprietary Limited (“MiX International”), a subsidiary of the Group, historically claimed a 150% allowance for research and development spend in terms of section 11D (“S11D”) of the South African Income Tax Act No. 58 of 1962 (“the Act”). As of October 1, 2012, the legislation relating to the allowance was amended. The amendment requires pre-approval of development project expenditure on a project specific basis by the South African Department of Science and Technology (“DST”) in order to claim a deduction of the additional 50% over and above the expenditure incurred (150% allowance). Since the amendments to S11D of the Act, MiX International had been claiming the 150% deduction resulting in a recognized tax benefit. MiX International has complied with the amended legislation by submitting all required documentation to the DST in a timely manner, commencing in October 2012. In June 2014, correspondence was received from the DST indicating that the research and development expenditure on certain projects for which the 150% allowance was claimed in fiscal 2013 and fiscal 2014 did not, in the DST’s opinion, constitute qualifying expenditure in terms of the Act. MiX International, through due legal process, had formally requested a review of the DST’s decision not to approve this expenditure. While approvals were obtained for a portion of this project expenditure as a result of a further review performed by the DST in February 2017, we continue to seek approval for the remaining projects and as such the legal process is ongoing. In addition to the approvals that were subject to the legal process, further approvals have been obtained for certain project expenditure, relating to both current and prior financial years. However, at period end, an uncertain tax position remains in relation to S11D deductions in respect of which approvals remain pending. Since the introduction of the DST pre-approval process, the Group has recognized in the income statement cumulative tax incentives in addition to the incurred cost of R20.5 million in respect of S11D deductions, of which R2.3 million was recognized in the current financial year. R17.7 million relates to deductions in respect of development project expenditure which has been approved by the DST. R2.8 million relates to an uncertain tax position in respect of projects where approvals have not yet been received from the DST. If the Group is unsuccessful in this regard, the Group will not recover the R2.8 million raised at March 31, 2018. The taxation receivable includes amounts due of R17.7 million in respect of S11D tax incentives at March 31, 2018 (2017: R14.9 million ).

Financial risk sensitivity analysis	Financial risk sensitivity analysis Interest rate sensitivity A change in the interest rate at the reporting date of 100 basis points for ZAR denominated instruments and 10 basis points for USD denominated instruments would have increased/(decreased) profit or loss before tax by the amounts shown below. This analysis assumes that all other variables remain constant. The analysis is performed on the same basis for the year ended March 31, 2017. March 31, 2018 March 31, 2017 USD denominated instruments Increase of 10 basis points * 143 Decrease of 10 basis points * (143 ) ZAR denominated instruments Increase of 100 basis points 1,811 1,000 Decrease of 100 basis points (1,811 ) (1,000 ) * Amount less than R 1,000 . Foreign currency sensitivity The Group has used a sensitivity analysis technique that measures the estimated change to profit or loss and equity of an instantaneous 5% strengthening or weakening in the functional currency against all other currencies, from the rate applicable at March 31, 2018, for each class of financial instrument with all other variables remaining constant. This analysis is for illustrative purposes only as, in practice, market rates rarely change in isolation. The Group is exposed mainly to fluctuations in foreign exchange rates in respect of the South African Rand, Australian Dollar, United States Dollar, the British Pound, the Brazilian Real and the Euro. This analysis considers the impact of changes in foreign exchange rates on profit or loss. A change in the foreign exchange rates to which the Group is exposed at the reporting date would have increased/(decreased) profit before taxation by the amounts shown below. The analysis has been performed on the basis of the change occurring at the end of the reporting period.

List Of Accounting Policies [Abstract]
Basis of presentation	Basis of preparation The annual financial statements of the Group for the year ended March 31, 2018 have been prepared in accordance with: • International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”); • IFRS Interpretations Committee (“IFRIC”) interpretations applicable to companies reporting under IFRS; • SAICA Financial Reporting guides as issued by the Accounting Practices Committee; • Financial Pronouncements as issued by the Financial Reporting Standards Council (“FRSC”); • the requirements of the South African Companies Act, No. 71 of 2008; and • the JSE Listings Requirements. The financial statements have been prepared in thousands of Rand (R’000) under the historical cost convention except for certain financial instruments that have been measured at fair value. The preparation of financial statements in accordance with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions or estimates are significant to the financial statements, are disclosed in note 4.
Changes in accounting policy and disclosures	Changes in accounting policy and disclosures 2.1.1.1 New standards, amendments and interpretations adopted by the Group Standards, amendments and interpretations which are effective for the financial year beginning on or after April 1, 2017 did not have a material impact on the Group. 2.1.1.2 New standards, amendments and interpretations not yet effective Certain new accounting standards and interpretations have been published that are not mandatory for the March 31, 2018 reporting period and have not been early adopted by the Group in fiscal 2018. The effect of adopting IFRS 9, IFRS 15 and IFRS 16 is set out below. Management is in the final stages of its project to adopt IFRS 9, IFRS 15 and IFRS 16 and as such the figures mentioned below represent our current expectations of the impact from these standards. Standards and amendments Executive summary IFRS 9 Financial Instruments (“IFRS 9”) IFRS 9 addresses classification and measurement of financial assets and replaces the multiple classification and measurement models in IAS 39 Financial Instruments: Recognition and Measurement with a single model that has only two classification categories: amortized cost and fair value. IFRS 9 also introduces a new impairment model and aligns hedge accounting more closely with an entity’s risk management. The standard is effective for the Group from April 1, 2018. The most relevant change to the Group is the requirement to use an expected loss model instead of the incurred loss model, which is currently being used, when assessing the recoverability of trade and other receivables. Based on the expected loss model contained in IFRS 9, the expected increase in the provision for doubtful debts at April 1, 2018 is between R2.0 million and R4.0 million. IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) IFRS 15 replaces IAS 18 Revenue and IAS 11 Construction Contracts . It is a single, comprehensive revenue recognition model for all contracts with customers and has the objective of achieving greater consistency in the recognition and presentation of revenue. In terms of the new standard, revenue is recognized based on the satisfaction of performance obligations, which occurs when control of goods or services transfers to a customer. The revenue standard is effective for annual periods beginning on or after January 1, 2018 and therefore is applicable for the Group from April 1, 2018. The standard permits a modified retrospective cumulative catch-up approach for the adoption, which the Group has decided to apply. Under this approach the Group will recognize transitional adjustments in retained earnings on the date of initial application (i.e. April 1, 2018), without restating the comparative period. Under the practical expedient, the new requirements only need to be applied to contracts that are not completed as of April 1, 2018. The Group has assessed the impact of applying IFRS 15 on its financial statements and has identified the following areas that will be affected: Costs incurred in obtaining a contract : Commissions incurred to acquire contracts need to be capitalized and amortized, unless the amortization period is 12 months or less. Currently, the Group expenses commissions. Under IFRS 15, the amortization expense reflects the settlement of the related performance obligations, which, depending on the specific contract, may include hardware, installation, training and/or service. To the extent commission capitalized is commensurate, the commission attributable to service will be amortized over the minimum contractual period or, if shorter, the expected life of the contract. To the extent it is not commensurate, the commission capitalized that is attributable to service will be amortized over the expected life of the contract. The expected impact on the Group at April 1, 2018 is as follows: — Capitalized commission asset with a net book value of between R43.0 million and R48.0 million; and — Additional recurring commission liability of between R6.0 million and R8.0 million. Recurring commission is commission which is payable for each month the customer remains with the Group. Since the commission relates to acquiring a customer contract, as part of the adoption of IFRS 15, a recurring commission liability will be recognized at the date on which the contract is acquired. The measurement will reflect the total commission payable over the minimum contractual period or, if shorter, the expected life of the contract, together with the effect of the time value of money, where significant. Under current accounting the recurring commissions are accrued for on a monthly basis. Amortization expense of external commissions capitalized under IFRS 15 will be recognized in cost of sales, while that of internal commissions will be recognized in sales and marketing costs. Commissions not capitalized under the 12-month practical expedient will also be classified in the same manner. This is in line with the current income statement presentation of the commission expense. The impact of IFRS 15 on both cost of sales and sales and marketing costs for fiscal 2019 is not expected to be material based on current forecasts. Standards and amendments Executive summary IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) Significant financing: In respect of contracts for which the Group receives payment more than 12 months in advance, interest expense will need to be accrued on the income received in advance liability. This will result in the revenue being measured at a higher amount when it is recognized, compared to current accounting. At April 1, 2018, it is expected that the income received in advance liability (which will be disclosed as ‘liabilities related to contracts with customers’) will be between R1.0 million and R3.0 million higher than the balance at March 31, 2018. Fixed escalations: Fixed escalations will need to be spread evenly over the contract period resulting in the related revenue being different to what is actually billed. In the earlier part of the contract, revenue will be higher than the amount billed, while in the latter part it will be lower. Currently, the Group recognizes the increase in revenue due to fixed escalations only once the escalations are effective. A contract asset of between R1.0 million and R2.0 million is expected to be recognized on April 1, 2018, reflecting the amount by which revenue should have been higher under IFRS 15 in periods prior to March 31, 2018 as a result of straight-lining the fixed escalations. IFRS 16 Leases (“IFRS 16”) IFRS 16 replaces IAS 17 Leases and addresses the accounting and disclosures for leases. IFRS 16 applies to annual reporting periods beginning on or after January 1, 2019, but can be early adopted. Given that the Group will be applying IFRS 15 from April 1, 2018, the Group decided to also adopt IFRS 16 from this date. The Group has chosen to apply the ‘simplified approach’ on adoption of IFRS 16 that includes certain relief related to the measurement of the right-of-use asset and the lease liability at April 1, 2018, rather than full retrospective application. Furthermore, the ‘simplified approach’ does not require a restatement of comparatives. The Group leases land and buildings, office equipment and vehicles which are currently treated as operating leases. The expected impact on the Group at April 1, 2018 is as follows: — Right-of-use asset with a net book value of between R29.0 million and R32.0 million; and — Lease liability (net of accruals/prepayments already recognized) of between R31.0 million and R35.0 million.
Business combinations	Business combinations The acquisition method of accounting is used to account for all business combinations, regardless of whether equity instruments or other assets are acquired. The consideration transferred for the acquisition of a subsidiary comprises the: • fair values of the assets transferred; • liabilities incurred to the former owners of the acquired business; • equity interests issued by the Group; • fair value of any asset or liability resulting from a contingent consideration arrangement; and • fair value of any pre-existing equity interest in the subsidiary. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are, with limited exceptions, measured initially at their fair values at the acquisition date. The Group recognizes any non-controlling interest in the acquired entity on an acquisition-by-acquisition basis either at fair value or at the non-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. Acquisition-related costs are expensed as incurred, except if related to the issue of equity securities, in which case these costs are also included in equity. The excess of the: • consideration transferred; • amount of any non-controlling interest in the acquired entity; and • acquisition-date fair value of any previous equity interest in the acquired entity over the fair value of the net identifiable assets acquired is recorded as goodwill. If those amounts are less than the fair value of the net identifiable assets of the subsidiary acquired, the difference is recognized directly in the income statement as a bargain purchase gain. Where settlement of any part of cash consideration is deferred, the amounts payable in the future are discounted to their present value as at the date of acquisition. The discount rate used is the entity’s incremental borrowing rate, being the rate at which a similar borrowing could be obtained from an independent financier under comparable terms and conditions. Unwinding of the interest element is recognized in the income statement. Contingent consideration is measured at fair value on acquisition date and classified either as equity or a financial liability. Amounts classified as a financial liability are subsequently remeasured to fair value with changes in fair value recognized in the income statement.
Changes in ownership interests in subsidiaries without a change of control	Subsidiaries Subsidiaries are all entities (including structured entities) over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the relevant activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. Inter-company transactions, balances and unrealized gains on transactions between Group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Group. Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated income statement, statement of comprehensive income, statement of changes in equity and statement of financial position, respectively. Changes in ownership interests in subsidiaries without a change of control The Group treats transactions with non-controlling interests that do not result in a loss of control as transactions with equity owners of the Group, that is, transactions with the owners in their capacity as owners. For purchases from non-controlling interests, the difference between the fair value of any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.
Segment reporting	Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (“CODM”). The CODM, who is responsible for allocating resources and assessing performance of the operating segments, has been identified collectively as the executive committee and the Chief Executive Officer who make strategic decisions. S ales between segments are carried out at cost plus a margin.
Functional and presentation currency	Functional and presentation currency Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in South African Rand (“R”), which is the Group’s presentation currency.
Transactions and balances and group companies	Group companies The results and financial position of foreign operations (none of which has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows: (i) Assets and liabilities for each statement of financial position presented are translated at the closing rate at the date of that statement of financial position; (ii) Income and expenses for each income statement presented are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions); (iii) All resulting exchange differences are recognized in other comprehensive income; and (iv) Equity items are measured at historical cost at the time of recording, translated at the rate on the date of the recording and are not retranslated to closing rates at reporting dates. On consolidation, exchange differences arising from the translation of net investments in foreign operations are recognized in other comprehensive income. When a foreign operation is fully disposed of or sold (i.e., control is lost), exchange differences that were recorded in equity are recognized in the income statement as part of the gain or loss on sale. A repayment/capitalization of a net investment loan therefore does not result in any exchange differences being transferred from equity to the income statement unless it is part of a transaction resulting in a loss of control. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing rate. Exchange differences are recognized in other comprehensive income. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year-end exchange rates are recognized in the income statement. Foreign exchange gains/(losses) are classified as “Finance income/(cost) — net”. Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation differences on non-monetary financial assets and liabilities such as equities classified as available-for-sale, are included in other comprehensive income.
Property, plant and equipment	Property, plant and equipment Property, plant and equipment is stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes all expenditure directly attributable to the acquisition of the items. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of any component accounted for as a separate asset is derecognized when replaced. Repairs and maintenance are charged to the income statement in the reporting period in which they are incurred. The cost of in-vehicle devices installed in vehicles (including installation and shipping costs) as well as the cost of uninstalled in-vehicle devices, is capitalized as property, plant and equipment. The Group depreciates installed in-vehicle devices on a straight-line basis over their expected useful lives, commencing upon installation, whereas uninstalled in-vehicle devices are not depreciated until installed. The related depreciation expense is recorded as part of cost of sales in the income statement. Land is not depreciated. Depreciation on other assets is calculated using the straight-line method to reduce their cost to their residual values over their estimated useful life, as follows: Property: Buildings 50 years Plant and equipment 3 — 20 years Motor vehicles 3 — 7 years Other: Furniture, fittings and equipment 1 — 10 years Computer and radio equipment 2 — 6 years In-vehicle devices installed 1 — 5 years The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period. An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount (note 2.7). Gains and losses on disposal of an asset are determined by comparing the proceeds with the carrying amount and are recognized within “Other income/(expenses) — net” in the income statement.
Intangible assets	Intangible assets (a) Goodwill Goodwill arises on the acquisition of businesses and represents the excess of consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the acquirer’s interest in the net fair value of the net assets acquired. Goodwill on acquisition of businesses is included in intangible assets. Gains and losses on the disposal of an entity include the carrying amount of the goodwill relating to the entity sold. Goodwill is not amortized but is tested annually for impairment, or more frequently if events or changes in circumstances indicate a potential impairment, and is carried at cost less accumulated impairment losses. Goodwill is allocated to cash-generating units (“CGUs”) for the purpose of impairment testing. The allocation is made to those CGUs or groups of CGUs that are expected to benefit from the business combination in which the goodwill arose. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal management purposes. Goodwill is monitored at the operating segment level. The carrying amount of the CGU containing the goodwill is compared to the recoverable amount, which is the higher of value-in-use and the fair value less costs to sell. Impairment losses recognized as an expense in relation to goodwill are not subsequently reversed. (b) Patents and trademarks Separately acquired patents and trademarks are shown at historical cost. Patents and trademarks acquired in a business combination are recognized at fair value at the acquisition date. Patents and trademarks have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. Amortization is calculated using the straight-line method to allocate the cost of patents and trademarks over their estimated useful lives ( three to 20 years ). (c) Customer relationships Customer relationships acquired in a business combination are recognized at fair value at the acquisition date. Customer relationships have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. Amortization is calculated over the expected useful life of the customer relationship ( two to 15.5 years ) and reflects the pattern in which future economic benefits of the customer relationship are expected to be consumed. The useful life principally reflects management’s view of the average economic life of the customer base and is assessed by reference to factors such as customer churn rates. (d) Computer software, technology, in-house software and product development costs Acquired computer software licenses are capitalized on the basis of costs incurred to acquire and bring the software into use. The acquired computer software licenses have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. These costs are amortized over their estimated useful lives ( two to five years ). In-house software and product development costs that are directly attributable to the design, testing and development of identifiable and unique software and products, controlled by the Group, are recognized as intangible assets when the following criteria are met: • It is technically feasible to complete the software or product so that it will be available for use; • Management intends to complete the software or product and use or sell it; • There is an ability to use or sell the software or product; • It can be demonstrated how the software or product will generate probable future economic benefits; • Adequate technical, financial and other resources to complete the development and use or sell the software or product are available; and • The expenditure attributable to the software or product during its development can be reliably measured. Directly attributable costs that are capitalized as part of the intangible assets include software and product development employee costs and an appropriate portion of relevant overheads. Other development expenditures that do not meet the criteria are recognized as an expense as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period if the criteria are subsequently met. Costs, including annual licenses, associated with maintaining computer software programs are recognized as an expense as incurred. Technology, in-house software and product development costs are capitalized on the basis of costs incurred to acquire and bring them into use. The recognized assets have a finite useful life and are subsequently carried at cost less accumulated amortization and accumulated impairment losses. In addition, they are amortized over their estimated useful lives ( one to 15 years ).
Impairment of non-financial assets	Impairment of non-financial assets Assets that have an indefinite useful life, goodwill and intangible assets that are not ready to use are not subject to amortization but are tested annually for impairment or more frequently if events or changes in circumstances indicate that they might be impaired. Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less cost to sell, and value-in-use. In assessing the value-in-use, the estimated future cash flows are discounted to their present value using the pre-tax discount rate that reflects current market assessments on the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (CGUs, i.e. operating segments). Non-financial assets other than goodwill that have suffered impairment are reviewed for possible reversal of the impairment at each reporting date.
Financial assets	Financial assets 2.8.1 Classification The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition. Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for those with maturities greater than 12 months after the end of the reporting period, which are classified as non-current assets. The Group’s loans and receivables comprise trade and other receivables, finance lease receivables, restricted cash and cash and cash equivalents in the statement of financial position. 2.8.2 Recognition and derecognition Regular way purchases and sales of financial assets are recognized on the trade date (the date on which the Group commits to purchase or sell the asset). Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. 2.8.3 Measurement Financial assets are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Loans and receivables Loans and receivables are subsequently carried at amortized cost using the effective interest method, less any impairment losses.
Impairment of financial assets	Impairment of financial assets The Group assesses, at the end of each reporting period, whether there is objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated. Loans and receivables Evidence of impairment may include indications that the debtors or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization and where observable data indicates that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults. For the loans and receivables category, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred), discounted at the financial asset’s original effective interest rate. The asset’s carrying amount is reduced and the amount of the loss is recognized in the income statement. If a loan has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the reversal of the previously recognized impairment loss is recognized in the income statement.
Fair value	Fair value Fair value is determined in accordance with IFRS 13 Fair Value Measurement and is categorized as follows: • Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices); and • Level 3: Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs). The carrying amounts for cash and cash equivalents, restricted cash, trade and other receivables (excluding pre-payments), trade and other payables (excluding leave pay) and the current portion of leases approximate fair value due to their short-term nature.
Offsetting financial instruments	Offsetting financial instruments Financial assets and liabilities are offset and the net amount reported in the statement of financial position when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis, or realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the Group or the counterparty.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined on a first-in, first-out (“FIFO”), actual cost or weighted average cost basis, depending on the nature of the Group entity in which it is held. The cost of finished goods includes the cost of manufacturing as charged by third parties. It excludes borrowing costs. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs necessary to make the sale.
Trade receivables	Trade receivables Trade receivables are amounts due from customers for goods sold or services performed in the ordinary course of business. If collection is expected in one year or less they are classified as current assets. If not, they are presented as non-current assets. Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less provision for impairment.
Net cash and cash equivalents	Net cash and cash equivalents Net cash and cash equivalents included in the statement of cash flows include cash on hand, deposits held on call with banks and bank overdrafts; all of which are available for use by the Group and have an original maturity of less than three months. Bank overdrafts are included within current liabilities on the statement of financial position.
Restricted cash	Restricted cash Restricted cash includes short-term deposits and amounts held that are not highly liquid and is accounted for as loans and receivables.
Stated capital	Stated capital Ordinary shares are classified as equity. Incremental external costs directly attributable to the issue of new shares or the exercise of share options are shown in equity as a deduction, net of tax, from the proceeds. Where any Group company purchases the Company’s equity instruments (treasury shares), the consideration paid, including any directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the owners of the parent as treasury shares until the shares are canceled or reissued. Where such ordinary shares are subsequently reissued, any consideration received, net of any directly attributable incremental transaction costs and the related income tax effects, is included in equity attributable to the owners of the parent.
Trade and other payables	Trade and other payables Trade and other payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade and other payables are initially recognized at fair value and are subsequently measured at amortized cost using the effective interest method.
Non-current assets held for sale	Non-current assets held for sale Non-current assets are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use and a sale is considered highly probable. They are measured at the lower of their carrying amount and fair value less costs to sell, except for assets such as deferred tax assets, assets arising from employee benefits, and financial assets, which are specifically exempt from this requirement. An impairment loss is recognized for any initial or subsequent write-down of the asset to fair value less costs to sell. A gain is recognized for any subsequent increases in fair value less costs to sell of an asset, but not in excess of any cumulative impairment loss previously recognized. A gain or loss not previously recognized by the date of the sale of the non-current asset is recognized at the date of derecognition. Non-current assets are not depreciated or amortized while they are classified as held for sale. Interest and other expenses attributable to the liabilities of a disposal group classified as held for sale continue to be recognized. Non-current assets classified as held for sale are presented separately from the other assets in the statement of financial position.
Taxation	Taxation 2.18.1. Current and deferred income taxes The tax expense for the year comprises current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively. In addition, to the extent the tax deduction in respect of equity-settled share-based payments exceeds the cumulative share-based payment expense, the tax is recognized directly in equity. The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period in the countries where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill; and neither are deferred tax liabilities nor deferred tax assets accounted for if they arise from the initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the deductible temporary differences can be utilized. Deferred tax (‘outside basis’ deferred tax) relating to temporary differences arising from investments in subsidiaries is considered as follows: • Deferred tax liabilities are recognized, except to the extent that the Group is able to control the timing of the reversal of the temporary differences, and it is probable that they will not reverse in the foreseeable future. • Deferred tax assets are recognized only to the extent that it is probable the temporary differences will reverse in the foreseeable future and there is sufficient taxable profit available against which the temporary differences can be utilized. Temporary differences arising from investments in subsidiaries in the consolidated financial statements are different from those arising in the Company financial statements. This is because in the Company financial statements, an investment in a subsidiary is carried at cost; whereas the carrying amount in the consolidated financial statements is the consolidated net assets of the subsidiary. Deferred tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the end of the reporting period and are expected to apply when the related deferred tax asset is realized or the deferred tax liability is settled. Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and when the deferred tax balances relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.
Dividend tax	Dividends tax Dividend withholding tax is currently payable at a rate of 20% (a rate of 15% was applicable for dividends paid before February 22, 2017) on dividends distributed to shareholders. This tax is not attributable to the Company but rather paid to the tax authorities on behalf of the shareholders through use of regulatory intermediaries, with only the net amount of the dividend being remitted to the shareholder.
Employee benefits	Employee benefits (a) Short-term benefits Remuneration to employees in respect of services rendered during a reporting period is recognized as an expense in that reporting period. Provision is made for accumulated leave and for short-term benefits when there is no realistic alternative other than to settle the liability, and there is a formal plan and the amounts to be paid are determined before the time of issuing the financial statements. (b) Defined contribution plan The Group operates defined contribution plans. A defined contribution plan is one under which the Group pays a fixed percentage of employees’ remuneration as contributions into a separate fund, and the Group will have no further legal or constructive obligations to pay additional contributions if the fund does not hold sufficient assets to pay all employee benefits relating to employee service in the current and prior periods. Contributions to defined contribution plans in respect of services rendered during a period are recognized as staff costs when they are due. (c) Short-term incentives — bonus plans The Group recognizes a liability and an expense for bonuses based on the achievement of defined key performance criteria. An accrual is recognized where the Group is contractually obliged or where there is a past practice that has created a constructive obligation. (d) Termination benefits Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognizes termination benefits at the earlier of the following dates: (a) when the Group can no longer withdraw the offer of those benefits; and (b) when the entity recognizes costs for a restructuring that is within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets , and involves payment of termination benefits. In the case of an offer made to encourage voluntary redundancy, the termination benefits are measured based on the number of employees expected to accept the offer. Benefits falling due more than 12 months after the end of the reporting period are discounted to their present value.
Share-based payments	Share-based payments Equity-settled The Group operates equity-settled share-based compensation plans, under which the entity receives services from employees as consideration for equity instruments of the Company. The equity instruments that may be issued in terms of the plans include share options, retention shares, performance shares and share appreciation rights. The fair value, determined at grant date, of the employee services received in exchange for the grant of equity instruments is recognized as an expense at Group level with a corresponding credit to equity. The total amount to be expensed is determined by reference to the grant date fair value of the equity instruments granted: • Including any market performance conditions; • Excluding the impact of any service and non-market performance vesting conditions (for example, remaining an employee of the entity over a specified time period); and • Including the impact of any non-vesting conditions. Non-market performance and service conditions are included in the assumptions about the number of equity instruments that are expected to vest. The total expense is recognized over the vesting period, which is the period over which all of the specified vesting conditions are to be satisfied. At the end of each reporting period, the Group revises its estimates of the number of equity instruments that are expected to vest based on the non-market vesting and service conditions. It recognizes the impact of the revision to original estimates, if any, in the income statement, with a corresponding entry to equity. When equity-settled instruments are exercised, the Company may elect to issue new shares or use treasury shares to settle its resultant obligations. For share options, the proceeds received, net of any directly attributable transaction costs, are credited to stated capital (as there are no par value shares). The grant by the Company of equity-settled instruments to the employees of subsidiary undertakings in the Group is treated as a capital contribution to those subsidiaries. The fair value of employee services received, measured by reference to the grant date fair value, is recognized over the vesting period as an increase to investment in subsidiary undertakings, with a corresponding credit to equity in the parent entity financial statements. During fiscal 2018, the Company implemented a recharge agreement with its South African subsidiaries, whereby the Company will recharge the relevant subsidiary an amount equal to the market value, at exercise date, of the shares issued to the participants of the plan upon exercise. A recharge asset is recognized in the parent entity financial statements from grant date of the equity-settled instruments for the expected recharge amount based on the proportion of the vesting period that has passed. The expected recharge amount reflects expected attrition and the current share price. The contra entry to the recharge asset is recognized against the relevant investment in subsidiary undertakings as it is considered a return of the afore-mentioned capital contribution. Once the carrying value of an investment in subsidiary undertakings has been reduced to nil, further recharges from that subsidiary are recognized in profit or loss as distributions. The Group classifies awards issued with settlement alternatives as equity-settled when the Group holds the choice of settlement and there is no past practice of settling in cash. If the counterparty holds the choice of settlement, the award is classified as cash-settled. Cash-settled For cash-settled share-based payment transactions, the Group measures goods or services acquired and the liability incurred at the fair value of the liability. Until the liability is settled, the Group shall remeasure the fair value of the liability at each reporting date and at the date of settlement, with any changes in fair value recognized in the income statement.
Provisions	Provisions Provisions are recognized when the Group has a present legal or constructive obligation as a result of a past event for which it is probable that an outflow of resources will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Provisions are not recognized for future operating losses. Provisions which are expected to be settled in a period greater than 12 months are discounted to their present value using a pre-tax discount rate that reflects current market assessment of the time value of money and the risks specific to the obligation. The increase in the provision due to the passage of time is recognized as an interest expense. Provision for the estimated liability on all products under warranty is made on the basis of claims experience. Provision for the estimated liability for maintenance costs is made on a per unit basis when the obligation to repair occurs. Provision for the anticipated costs associated with the restoration of leasehold property (decommissioning provision) is based on the Group’s best estimate of those costs required to restore the property to its original condition. Restructuring provisions are recognized when the Group has developed a detailed formal plan for restructuring and has raised a valid expectation that it will carry out the restructuring by starting to implement the plan or announcing its main features to those affected by it. The measurement of a restructuring provision includes only the direct expenditures arising from the restructuring and is recorded in administration and other charges in the income statement.
Revenue recognition	Revenue recognition Revenue is measured at the fair value of the consideration received or receivable for the sale of goods or services in the ordinary course of the Group’s activities. Revenue mainly includes amounts earned on the sale of hardware units, subscription service sales to customers and installation revenue. Revenue is shown net of discounts, value added tax, returns and after eliminating sales within the Group. The Group offers certain arrangements whereby the customer can purchase a combination of the products and services as referred to above. Where such multiple element arrangements exist, the amount of revenue allocated to each element is based on the relative fair values of the various elements offered in the arrangement. When applying the relative fair value approach, the fair values of each element are determined based on the current market price of each of the elements when sold separately. The Group recognizes revenue when the amount of revenue can be measured reliably and it is probable that future economic benefits will flow to the entity and specific criteria have been met for each of the Group’s activities, as outlined below. The Group bases its estimates on historical results, taking into consideration the type of customer, the type of transaction and the specifics of each arrangement. Invoicing for the various products and services, when sold separately or as part of a multiple element revenue arrangement, occurs based on the specific contractual terms and conditions. The Group distributes products to certain small fleet operators and consumers through distributors. Distributors act as agents and hardware revenue is only recognized when the distributor sells the hardware unit to the end customer. Once a unit is sold to a customer, the customer enters into a service agreement directly with the Group for the product. The obligation to supply the service and the credit risk rests with the Group. The service revenue is recognized when the service is rendered (i.e. on a monthly basis). The Group also sells hardware to motor vehicle dealerships for fitment into their vehicle trading stock. These dealerships purchase the hardware from the Group and are considered principals because they obtain title to the hardware and bear the risks and rewards of ownership. The buyer of the vehicle then enters into a service-only contract with the Group. Revenue is recognized upon sale of the hardware to the dealership and subscription revenue is recognized as the services are provided to the customer. The Group distributes products to enterprise fleet customers through dealers. Dealers are considered principals in respect of the sale of hardware and revenue is recognized upon sale of the hardware unit to the dealer. Similar to the relationship with consumers and small fleet customers originated through distributors, the responsibility for providing services rests with the Group and revenue is recognized as the service is rendered. (a) Subscription revenue Subscription revenue is recognized over the term of the agreement as it is earned. When contracted services are performed through a number of repetitive acts over the contract period, revenue is recognized on a straight-line basis over the contract period. (b) Hardware sales All hardware has value on a standalone basis. Revenue from hardware sales is recognized once the risks and rewards of ownership have transferred. (c) Driver training and other services Revenue is recognized at the contractual hourly/daily rate as the training is performed. (d) Rental revenue Where hardware is provided as part of a service contract the risk and rewards of ownership do not transfer and service revenue from the rental unit is recognized over the period of the service and included in subscription revenue. (e) Installation revenue Revenue earned from the installation of hardware in customer vehicles is recognized once the installation has been completed. (f) Repair services Revenue in respect of repair services, which forms part of the monthly subscription, is recognized on a monthly basis over the period of the service arrangement.
Interest income	Interest income Interest income is recognized on a time-proportion basis with reference to the principal amount receivable and the effective interest rate applicable.
Dividend income	Dividend income Dividend income is recognized when the right to receive payment is established.
Leases	Leases Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases. 2.25.1. The Group as a lessor When assets are leased out under a finance lease, the present value of the minimum lease payments is recognized as a receivable. The difference between the gross receivable and the present value of the receivable is recognized as unearned finance income. The method for allocating gross earnings is referred to as the actuarial method. The actuarial method allocates rentals between finance income and repayment of capital in each accounting period in such a way that finance income will emerge as a constant rate of return on the lessor’s net investment in the lease. Assets leased under operating leases are included under the appropriate category of assets in the statement of financial position. Lease income on operating leases is recognized over the term of the lease on a straight-line basis. 2.25.2. The Group as a lessee Payments made under operating leases are charged to the income statement on a straight-line basis over the term of the lease.
Dividend distribution	Dividend distribution Any dividend distribution to the Company’s shareholders is recognized as a liability in the financial statements in the period in which the dividends are approved by the Company’s Board of Directors.
Financial risk management	Financial risk management 3.1 Financial risk factors The Group’s activities expose it to a variety of financial risks: market risk (including foreign exchange risk, interest rate risk, and price risk), credit risk, and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets as it relates to financial risks and seeks to minimize potential adverse effects on the Group’s financial performance. Risk management is carried out under policies approved by the Board of Directors. The Board has provided approved formal policies covering specific areas, such as foreign exchange risk as well as cash management and banking facilities. (a) Market risk (i) Foreign exchange risk The Group operates internationally and is exposed to foreign exchange risk arising from various currencies, primarily with respect to the United States Dollar, the South African Rand, the Euro, the Australian Dollar, the Brazilian Real and the British Pound. Foreign exchange risk arises when future commercial transactions or recognized assets and liabilities and net investments in foreign operations are denominated in a currency that is not the entity’s functional currency. The Group has implemented a foreign currency hedging policy to limit the Group’s exposure to fluctuations in foreign currencies. The foreign currency policy reduces exchange rate risk on certain recognized assets and liabilities based on economic hedging principles as opposed to using derivative financial instruments. The Group has certain investments in foreign operations, whose net assets are exposed to foreign currency translation risk. Currency exposure arising from the assets of the Group’s foreign operations is reduced as a result of assets and liabilities being denominated in the same foreign currencies. As a result of our cash reserves being held in multiple currencies, the Group has significant foreign currency exposure. A financial risk sensitivity analysis is presented in note 36. (ii) Interest rate risk Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Group’s cash flow interest rate risk arises from restricted cash, cash and cash equivalents and the bank overdraft. Bank overdrafts issued at variable rates expose the Group to cash flow interest rate risk, which is partly offset by financial assets held at variable rates (i.e. cash and cash equivalents and restricted cash). At March 31, 2018 and 2017 the Group had no interest-bearing borrowings. The Group is not exposed to fair value interest rate risk as the Group does not have any fixed rate interest-bearing financial instruments carried at fair value. Interest rates are constantly monitored and appropriate steps are taken to ensure that the Group’s exposure to interest rate fluctuations is limited. This includes obtaining approval from the Board for all changes to and new borrowing facilities entered into. Refer to note 36 for an interest rate risk sensitivity analysis. (iii) Price risk Currently the Group does not have significant price risk. The Group is not exposed to commodity price risk. (b) Credit risk Credit risk is the risk that a counterparty to a financial instrument will fail to discharge an obligation and cause the Group to incur a financial loss. Credit risk arises from restricted cash, cash and cash equivalents as well as credit exposures to customers. The maximum exposure to credit risk is represented by the carrying amount of each financial asset in the statement of financial position, net of impairment losses where relevant. Credit risk relating to accounts receivable balances is managed by each local entity which is responsible for managing and analyzing the credit risk for each of their new clients before standard payment and delivery terms and conditions are offered. The Group has a policy in place governing the allowance for credit losses. Cash investments are only placed with reputable financial institutions rated BB and above (note 12). All changes in or new banking arrangements entered into are in line with the Board’s approval framework. Refer to note 10 for further disclosure on credit risk. (c) Liquidity risk Liquidity risk is the risk that there will be insufficient funds available to settle obligations when they are due. The Group has limited liquidity risk due to surplus cash balances and the recurring nature of its income, which generates strong cash inflows. The level of cash balances in the Group is monitored weekly and cash generated from operations is reviewed against planned cash flows on a monthly basis. In addition, working capital reviews are performed monthly. Surplus cash is invested in interest-bearing current accounts and time deposits that are expected to readily generate cash inflows for managing liquidity risk. In addition, the Group maintains headroom on its undrawn borrowing facilities to ensure that the Group does not breach borrowing limits on its borrowing facilities. Refer to note 37 for further disclosure on liquidity risk.
Capital risk management	Capital risk management The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern while enhancing the returns for shareholders and ensuring benefits for other stakeholders. The Board of Directors monitors capital by reviewing the net cash position. The Company currently has no long-term borrowings and none of its overdraft facilities, as set out in note 15, were subject to any financial covenants during fiscal 2018 and fiscal 2017. In order to maintain the capital structure, the Group may return capital to shareholders, issue new shares or sell assets to reduce debt, where applicable.
Critical accounting estimates and judgements	Critical accounting estimates and judgements Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have significant risk of causing a material adjustment to the carrying amounts of assets and liabilities during fiscal 2018 are outlined below: (a) Warranty claims The Group generally offers warranties on its hardware units. Management estimates the related provision for future warranty claims based on historical warranty claim information, as well as recent trends that might suggest that past cost information may differ from future claims. (b) Maintenance provision The Group, in some instances, offers maintenance services as part of its revenue contracts. Management estimates the related provision for maintenance costs per vehicle when the obligation to repair occurs. (c) Current and deferred income taxes The Group is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the worldwide provision for income taxes. Where applicable tax legislation is subject to interpretation, management makes assessments, based on expert tax advice, of the relevant tax that is likely to be paid and provides accordingly. When the final outcome is determined and there is a difference, this is recognized in the period in which the final outcome is determined. Determining how much tax to recognize when an uncertain tax position exists requires judgement. The Group applies the measurement principle in IAS 12 Income Taxes , when measuring the amount of tax to recognize related to an uncertain tax position. Therefore, the Group measures uncertain tax positions based on a weighted average estimate, taking into account all of the tax uncertainties related to the tax position taken. The Company's interests in subsidiaries include certain loans denominated in foreign currencies which are repayable by agreement of both parties. Realization of such loans will result in taxable foreign exchange differences in accordance with prevailing legislation in South Africa. Although the Company controls the timing of the reversal of these temporary differences, given the volatility of the South African Rand and based on the Group's current assessment, it is not considered probable that the temporary difference relating to a loan between the Company and a South Africa subsidiary will not reverse in the foreseeable future. Hence, a deferred tax liability has been recognized in respect of these temporary differences (note 18). The Group applies judgement when recognizing deferred tax assets in respect of tax losses. Deferred tax assets in respect of tax losses are recognized for the carry forward of unused tax losses to the extent that it is probable that future taxable profit will be available against which the unused tax losses can be utilized. In determining the level of future taxable profit that will be available the Group considers both an entity's historical profitability and estimates of future profitability and recognizes deferred tax for the whole or the part of the temporary difference that is more likely than not to be recovered. Where an entity has incurred historical losses, deferred tax assets are only recognized when the particular entity has shown a reasonable period of starting to return to profitability. (d) Impairment estimates The Group tests annually whether goodwill has suffered any impairment in accordance with the accounting policy stated in note 2.7. Other assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. For the purposes of assessing impairment, assets are grouped into CGUs at the lowest levels for which there are separately identifiable cash flows. The recoverable amount is based on the CGU’s value-in-use. These calculations require the use of estimates (see notes 6 and 7). (e) Customer relationships T he useful life applied principally reflects management’s view of the average economic life of the customer base and is assessed by reference to factors such as customer churn rates. An increase in churn rates may lead to a reduction in the estimated useful life. (f) Product development cost Product development cost directly attributable to the design and testing of identifiable and unique software products controlled by the Group are recorded as intangible assets by the Group when the criteria in note 2.6 have been met. The assessment as to when these criteria have been met is subjective and capitalization has been based on management’s best judgement of facts and circumstances in existence at year-end. The useful lives of development costs capitalized are reviewed on an at least annual basis. The useful life estimates are based on historical experience with similar assets as well as anticipation of future events such as technological changes, which may impact the useful life. The residual values of product development costs are estimated to be zero. (g) Provision for impairment of trade receivables The provision for impairment of trade receivables reflects the Group’s estimates of losses arising from the failure or inability of the Group’s customers to make required payments. The provision is based on the ageing of customer accounts, customer creditworthiness and the Group’s historical write-off experience. Changes to the allowance may be required if the financial condition of the Group’s customers improves or deteriorates. An improvement in financial condition may result in lower actual write-offs. Historically, changes to the estimate of losses have not been material to the Group’s financial position and results. (h) Allocation between in-vehicle devices and inventory The allocation between in-vehicle devices and inventory reflects the Group’s estimates of how units are expected to be sold, thereby it is a significant area of judgement for the Group.

List Of Accounting Policies [Abstract]
Impact of new standards, amendments, and interpretations not yet effective	Certain new accounting standards and interpretations have been published that are not mandatory for the March 31, 2018 reporting period and have not been early adopted by the Group in fiscal 2018. The effect of adopting IFRS 9, IFRS 15 and IFRS 16 is set out below. Management is in the final stages of its project to adopt IFRS 9, IFRS 15 and IFRS 16 and as such the figures mentioned below represent our current expectations of the impact from these standards. Standards and amendments Executive summary IFRS 9 Financial Instruments (“IFRS 9”) IFRS 9 addresses classification and measurement of financial assets and replaces the multiple classification and measurement models in IAS 39 Financial Instruments: Recognition and Measurement with a single model that has only two classification categories: amortized cost and fair value. IFRS 9 also introduces a new impairment model and aligns hedge accounting more closely with an entity’s risk management. The standard is effective for the Group from April 1, 2018. The most relevant change to the Group is the requirement to use an expected loss model instead of the incurred loss model, which is currently being used, when assessing the recoverability of trade and other receivables. Based on the expected loss model contained in IFRS 9, the expected increase in the provision for doubtful debts at April 1, 2018 is between R2.0 million and R4.0 million. IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) IFRS 15 replaces IAS 18 Revenue and IAS 11 Construction Contracts . It is a single, comprehensive revenue recognition model for all contracts with customers and has the objective of achieving greater consistency in the recognition and presentation of revenue. In terms of the new standard, revenue is recognized based on the satisfaction of performance obligations, which occurs when control of goods or services transfers to a customer. The revenue standard is effective for annual periods beginning on or after January 1, 2018 and therefore is applicable for the Group from April 1, 2018. The standard permits a modified retrospective cumulative catch-up approach for the adoption, which the Group has decided to apply. Under this approach the Group will recognize transitional adjustments in retained earnings on the date of initial application (i.e. April 1, 2018), without restating the comparative period. Under the practical expedient, the new requirements only need to be applied to contracts that are not completed as of April 1, 2018. The Group has assessed the impact of applying IFRS 15 on its financial statements and has identified the following areas that will be affected: Costs incurred in obtaining a contract : Commissions incurred to acquire contracts need to be capitalized and amortized, unless the amortization period is 12 months or less. Currently, the Group expenses commissions. Under IFRS 15, the amortization expense reflects the settlement of the related performance obligations, which, depending on the specific contract, may include hardware, installation, training and/or service. To the extent commission capitalized is commensurate, the commission attributable to service will be amortized over the minimum contractual period or, if shorter, the expected life of the contract. To the extent it is not commensurate, the commission capitalized that is attributable to service will be amortized over the expected life of the contract. The expected impact on the Group at April 1, 2018 is as follows: — Capitalized commission asset with a net book value of between R43.0 million and R48.0 million; and — Additional recurring commission liability of between R6.0 million and R8.0 million. Recurring commission is commission which is payable for each month the customer remains with the Group. Since the commission relates to acquiring a customer contract, as part of the adoption of IFRS 15, a recurring commission liability will be recognized at the date on which the contract is acquired. The measurement will reflect the total commission payable over the minimum contractual period or, if shorter, the expected life of the contract, together with the effect of the time value of money, where significant. Under current accounting the recurring commissions are accrued for on a monthly basis. Amortization expense of external commissions capitalized under IFRS 15 will be recognized in cost of sales, while that of internal commissions will be recognized in sales and marketing costs. Commissions not capitalized under the 12-month practical expedient will also be classified in the same manner. This is in line with the current income statement presentation of the commission expense. The impact of IFRS 15 on both cost of sales and sales and marketing costs for fiscal 2019 is not expected to be material based on current forecasts. Standards and amendments Executive summary IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) Significant financing: In respect of contracts for which the Group receives payment more than 12 months in advance, interest expense will need to be accrued on the income received in advance liability. This will result in the revenue being measured at a higher amount when it is recognized, compared to current accounting. At April 1, 2018, it is expected that the income received in advance liability (which will be disclosed as ‘liabilities related to contracts with customers’) will be between R1.0 million and R3.0 million higher than the balance at March 31, 2018. Fixed escalations: Fixed escalations will need to be spread evenly over the contract period resulting in the related revenue being different to what is actually billed. In the earlier part of the contract, revenue will be higher than the amount billed, while in the latter part it will be lower. Currently, the Group recognizes the increase in revenue due to fixed escalations only once the escalations are effective. A contract asset of between R1.0 million and R2.0 million is expected to be recognized on April 1, 2018, reflecting the amount by which revenue should have been higher under IFRS 15 in periods prior to March 31, 2018 as a result of straight-lining the fixed escalations. IFRS 16 Leases (“IFRS 16”) IFRS 16 replaces IAS 17 Leases and addresses the accounting and disclosures for leases. IFRS 16 applies to annual reporting periods beginning on or after January 1, 2019, but can be early adopted. Given that the Group will be applying IFRS 15 from April 1, 2018, the Group decided to also adopt IFRS 16 from this date. The Group has chosen to apply the ‘simplified approach’ on adoption of IFRS 16 that includes certain relief related to the measurement of the right-of-use asset and the lease liability at April 1, 2018, rather than full retrospective application. Furthermore, the ‘simplified approach’ does not require a restatement of comparatives. The Group leases land and buildings, office equipment and vehicles which are currently treated as operating leases.

Refer to note 18 for details about deferred taxes recognized for related temporary differences. ** During fiscal 2008, the Group acquired a non-controlling equity interest held by a minority shareholder in one of its subsidiaries in exchange for a share consideration. R137.9 million (2017: R137.9 million ) of the reserve represents the difference between the consideration paid and the Group’s share in the net asset value of the subsidiary acquired which has been recorded in equity. The reserve on transaction with non-controlling interests represented the transfer of Edge Gestao Empresarial Ltda's ( “ Edge ” ) share of the historical losses of MiX Telematics Servicos De Tlematria E Rastremento De Veiculos Do Brazil Limitada (“MiX Brazil”) from distributable reserves to non-controlling interests. R0.5 million , representing a reduction of the reserve, relates to the transaction with Edge in fiscal 2015, whereby Edge increased its non-controlling interest in MiX Brazil from 0.0025% to 5.0% . R1.5 million of the non-controlling interest relates to the acquisition of Edge's 5% interest in MiX Brazil by MiX Investments (Proprietary) Limited (“MiX Investments”) during fiscal 2018 (note 20).

During prior years, deferred tax assets have not been recorded for assessed losses in the Americas and Brazil. (4) The foreign tax paid relates primarily to withholding taxes on revenue earned in jurisdictions where the Group does not have a legal entity. (5) The tax incentives relate mainly to the section 11D allowance detailed below.
