Disclosure Of Corporate Information [Abstract]
Corporate information	1. Corporate information Farfetch Limited (the “Company”) is an exempted company incorporated with limited liability under the Companies Law (2018 Revision) of the Cayman Islands, as amended and restated from time to time (the “Companies Law”). The principal place of business is The Bower, 211 Old Street, London, EC1V 9NR, United Kingdom. Farfetch Limited and its subsidiary undertakings (the “Group”) is principally engaged in the following: • providing an online marketplace at Farfetch.com (and related suffixes) as well as the Farfetch app for retailers and brands to be able to offer their products for sale to the public (including associated services such as ‘production’, logistics, customer services and payment processing); • web design, build, development and retail distribution for retailers and brands to enable them to offer their products to the public; and • operating the Company-owned (Browns, New Guards, Stadium Goods) and the branded stores (Off-White). Summary of impact of Group restructure and Initial Public Offering (IPO) On September 21, 2018, the Company commenced trading its shares on the New York Stock Exchange. In preparation for this IPO, the Group was restructured. The steps to restructure the Group had the effect of Farfetch Limited being inserted above Farfetch.com Limited as the holder of the Farfetch.com Limited share capital. The reorganization transactions have been treated as a capital reorganization. In accordance with International Financial Reporting Standards, historic earnings per share calculations and the balance sheet as of December 31, 2017 have been restated retrospectively to reflect the capital structure of the new parent rather than that of the former parent, Farfetch.com Limited. The Group is presented as if Farfetch Limited has always owned Farfetch.com Limited. The comparative statement of operations and statement of financial position are presented in line with the previously presented Farfetch.com Limited position. The comparative and current period consolidated reserves of the Group are adjusted to reflect the statutory share capital and share premium of Farfetch Limited. A merger reserve arose as a result of the restructuring of the Group and represents the difference between the equity of the acquired company (Farfetch.com Limited) and the investment by the acquiring company (Farfetch Limited). The steps taken to restructure the Group were as follows. On September 18, 2018, all holders of warrants over Farfetch.com shares, except a holder of 189,995 warrants, exercised their warrants into the applicable class of shares and the outstanding shares of Farfetch.com and were exchanged for shares of Farfetch Limited with equivalent rights. Following the exchange, the £0.10 British Pound Sterling denominated ordinary shares and the preference shares held by the shareholders of Farfetch Limited were converted into U.S. dollar denominated $0.20 ordinary shares of Farfetch Limited and subsequently exchanged, one for five, for $0.04 Class A ordinary shares and Class B ordinary shares, as applicable. Outstanding options of Farfetch.com were released in exchange for the grant of options with equivalent rights over Class A ordinary shares of Farfetch Limited.

Disclosure Of Accounting Policies [Abstract]
Significant accounting policies	2. 2.1. The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The Directors have made an assessment of the Group’s ability to continue in operational existence for the foreseeable future and are satisfied that it is appropriate to continue to adopt the going concern basis of accounting in preparing the consolidated financial statements. The consolidated financial statements have been prepared under the historical cost convention unless otherwise stated. The consolidated financial statements are presented in United States dollars (“U.S. dollars” or “USD” or “$”). All values are rounded to the nearest thousand dollars, except where indicated. The tables in these notes are shown in USD thousands, except where indicated. In January 2019, the functional currency of Farfetch UK Limited, the Group’s primary trading entity, changed from pound sterling to U.S dollars. This was a result of a gradual change in the primary economic environment in which Farfetch UK Limited operates driven by the growth of consumers where the Group receives U.S. dollars in settlement. This is combined with an increase in costs influenced by movements in the U.S dollar. The Group’s corporate treasury function continually monitors the Group’s exposure to foreign currency movements. Farfetch UK Limited is exposed to movements in several key currencies including the U.S dollar, euro and pound sterling. Following review of Farfetch UK Limited’s expected receipts and expenses, the Group determined that U.S dollars had become the dominant currency from January 2019. As a result this has triggered a change in functional currency. Effective January 1, 2019, we adopted the requirements of IFRS 16, Leases, (“IFRS 16”) as discussed below. The consolidated financial statements provide comparative information in respect of the previous periods. 2.2. The consolidated financial statements comprise the consolidated financial statements of the Group and its subsidiaries. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including: • The contractual arrangement with the other vote holders of the investee; • Rights arising from other contractual arrangements; and • The Group’s voting rights and potential voting rights. The Group re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Group gains control until the date control ceases. Profit or loss and each component of other comprehensive income (“OCI”) are attributed to the equity holders of the parent of the Group and to the non-controlling interests. When necessary, adjustments are made to the consolidated financial statements of subsidiaries to bring their accounting policies into line with the Group’s accounting policies. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation. A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. 2.3. a) Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred measured at acquisition date fair value and the amount of any non-controlling interests in the acquiree. For each business combination, the Group measures the non-controlling interests in the acquiree at the proportionate share of the acquiree’s identifiable net assets. When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. Any contingent consideration to be transferred by the Group is recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and is measured at fair value with changes in fair value recognized in profit or loss. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interests over the net identifiable assets acquired and liabilities assumed which are measured at fair value at the date of acquisition. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units (“CGU”) that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Annual impairment testing is performed at every reporting date being December 31. Refer to Note 2.3m) for the Group’s policy on the impairment of non-financial assets. b) The Group recognizes an associate when the Group has a significant influence over that entity. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies. The Group’s investment in its associate, Farfetch Finance Limited, is accounted for using the equity method. Under the equity method of accounting, the investments are initially recognized at cost and adjusted thereafter to recognize the Group’s share of the post-acquisition profits or losses of the investee in profit or loss, and the Group’s share of movements in other comprehensive income of the investee in other comprehensive income. c) The Group presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset is current when it is: • Expected to be realized or intended to be sold or consumed in the normal operating cycle; • Held primarily for the purpose of trading; • Expected to be realized within twelve months after the reporting period; or • Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as non-current. A liability is current when: • It is expected to be settled in the normal operating cycle; • It is held primarily for the purpose of trading; • It is due to be settled within twelve months after the reporting period; or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period. The Group classifies all other liabilities as non-current. d) This section outlines the Group policies applicable to financial instruments that are recognized and measured at fair value in the consolidated financial statements. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • In the principal market for the asset or liability; or • In the absence of a principal market, in the most advantageous market for the asset or liability. The principal or the most advantageous market must be accessible by the Group. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data is available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: • Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities • Level 2: Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable • Level 3: Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable For assets and liabilities that are recognized in the consolidated financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period. e) Revenue is recognized in accordance with the five-step model under IFRS 15, which was early adopted by the Group on January 1, 2017 on a fully retrospective basis: 1. identifying the contracts with customers; 2. identifying the separate performance obligations; 3. determining the transaction price; 4. allocating the transaction price to the separate performance obligations; and 5. recognizing revenue when each performance obligation is satisfied. Retailing of goods Revenue, where the Group acts as a principal, is recognized when the performance obligation is satisfied which is when the goods are received by the consumer. Included within sales of goods is a provision for expected returns, discounts and rebates. Where these are not known, the Group uses historical data and patterns to calculate an estimate. Rendering of services The Group primarily acts as a commercial intermediary between sellers, being the brands and retailers, and end consumers and earns a commission for this service. For these arrangements, the sellers determine the transaction price of the goods sold on the website, being the purchase price paid by the consumer, with the Group acting as an agent for the sellers and the related revenue is recognized on a net basis. The Group also charges fees to sellers for activities related to providing this service, such as packaging, credit card processing, settlement of duties, and other transaction processing activities. These activities are not considered separate promises to the consumer, and the related fees are therefore recognized concurrently with commissions at the time the performance obligation to facilitate the transaction between the seller and end consumer is satisfied, which is when the goods are dispatched to the end consumer by the seller. A provision is made for commissions that would be refunded if the end consumer returns the goods, and the Group uses historical data and patterns to estimate its return provision. There are no significant payment terms with the Group taking payment in full from the consumer’s chosen payment method at the time the goods are dispatched by the seller. The Group also provides delivery services to end consumers, with the Group setting the transaction price, for goods purchased on its platform. For these services, the Group acts as the principal and recognizes as revenue amounts charged to end consumers net of any promotional incentives and discounts. Revenue for these services is recognized on delivery of goods to the end consumer, which represents the point in time at which the Group’s performance obligation is satisfied. No provision for returns is made as delivery revenue is not subject to refund. Promotional incentives, which include basket promo-code discounts, may periodically be offered to end consumers. These are treated as a deduction to revenue. Cash is collected by the Group from the end consumer using payment service providers. Within two months of the transactions, this is remitted to the relevant seller (net of commission and recoveries). Such amounts are presented within trade and other payables, unless the relevant seller is in a net receivable position and is therefore classified within trade and other receivables. f) Current tax is the expected tax payable based on the taxable profit for the period, and the tax laws that have been enacted or substantively enacted by the reporting date. 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 recognized on differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit, and is accounted for using the balance sheet liability method. Deferred tax liabilities are generally recognized for all taxable temporary differences and deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit. Current and deferred tax is charged or credited in the statement of operations, except when it relates to items charged or credited directly to equity, in which case the current or deferred tax is also recognized directly in equity. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates and in accordance with laws that are expected to apply in the period/jurisdiction when/where the liability is settled, or the asset is realized. Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities and where there is an intention to settle the balances on a net basis. g) The Group’s consolidated financial statements are presented in U.S. dollars. For each entity the Group determines the functional currency and items included in the consolidated financial statements of each entity are measured using that functional currency. The functional currency of the Company is U.S. dollars. h) Transactions in foreign currencies are initially recorded by the Group’s entities at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rates of exchange at the reporting date. Differences arising on settlement or translation of monetary items are recognized in profit or loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined. The gain or loss arising on translation of non-monetary items measured at fair value is treated in line with the recognition of the gain or loss on the change in fair value of the item (i.e., translation differences on items whose fair value gain or loss is recognized in OCI or profit or loss are also recognized in OCI or profit or loss, respectively). On consolidation, the assets and liabilities of foreign operations are translated into U.S. dollars at the rate of exchange prevailing at the reporting date and their statements of profit or loss are translated at average exchange rates. The exchange differences arising on translation for consolidation are recognized in OCI. i) Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. All repair and maintenance costs are recognized in profit or loss as incurred. Items of property, plant and equipment are depreciated with an expense recognized in depreciation and amortization expense on a straight-line basis over their useful life. The useful lives of these items are assessed as follows: Leasehold improvements Shorter of the life of the lease or useful life Fixtures and fittings Three to ten years Motor vehicles Four to eight years Plant, machinery and equipment Leased plant and equipment Three to ten years Three to eight years The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate. The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement. j) Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Internally generated intangibles, excluding capitalized development costs, are not capitalized and the related expenditure is reflected in profit or loss in the period in which the expenditure is incurred. The useful lives of intangible assets are assessed as either finite or indefinite. Intangible assets with finite lives are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of operations in the expense category that is consistent with the function of the intangible assets. Other than goodwill, there are no intangible assets with indefinite useful lives. Goodwill is not amortized but is reviewed for impairment at least annually. For the purpose of impairment testing, goodwill is allocated to the relevant CGUs which are tested for impairment annually. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro-rata on the basis of the carrying amount of each asset in the unit. On disposal of a cash-generating unit, the attributable amount of goodwill is included in the determination of the profit or loss on disposal. Refer to Note 2.3m) for the Group’s policy on the impairment of non-financial assets. Research and development costs Research costs are expensed as incurred. Development expenditures on an individual project are recognized as an intangible asset when the Group can demonstrate: • The technical feasibility of completing the intangible asset so that the asset will be available for use or sale; • Its intention to complete and its ability and intention to use or sell the asset; • How the asset will generate future economic benefits; • The availability of resources to complete the asset; and • The ability to measure reliably the expenditure during development. Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortization and accumulated impairment losses. Amortization of the asset begins when development is complete and the asset is available for use. It is amortized over the period of expected future benefit. Amortization is recorded in administrative expenses. Development intangible assets under the course of construction are tested for impairment annually or more frequently if events or changes in circumstance indicate that they might be impaired. Once placed into service the asset is tested for impairment whenever events or changes in circumstance indicate that the carrying amount may not be recoverable. Subsequent costs Subsequent costs are only capitalized when there is an increase in the anticipated future economic benefit attributable to the assets in question. All other subsequent costs are recorded in the statement of operations for the year in which they are incurred. Amortization Amortization is charged to depreciation and amortization expense on a straight-line basis over the estimated useful life of the intangible assets, from the time that the assets are available for use. The useful lives of these items are assessed as follows: Development costs Three years Brand, trademarks & domain names Five to sixteen years Customer relationships Three to five years k) Inventories are carried at the lower of cost and the net realizable value based on market performance, including the relative ancillary selling costs. The cost of inventories, calculated according to the weighted average cost method for each category of goods, includes purchase costs and costs incurred to bring the inventories to their present location and condition. In order to represent the value of inventories appropriately in the statement of financial position, and to take into account impairment losses due to obsolete materials and slow inventory movement, obsolescence provisions have been directly deducted from the carrying amount of the inventories. l) A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets The Groups financial assets comprise cash and cash equivalents, receivables and derivative financial instruments. Derivative financial instruments are comprised of forward exchange contracts, which are measured at fair value through profit or loss, unless they are formally designated and measured as cash flow hedges. Trade receivables are generally accounted for at amortized cost. The Group assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized cost. Financial assets through profit or loss are measured initially at fair value with transaction costs taken directly to the consolidated statement of operations. Subsequently, the financial assets are remeasured, and gains and losses are recognized in the consolidated statement of operations. Financial liabilities The Group’s financial liabilities comprise trade and other payables, interest bearing loans and borrowings, contingent consideration and foreign exchange contracts. Trade and other payables are held at amortized cost. All interest bearing loans and borrowings are initially recognized at fair value net of issue costs associated with the borrowing. After initial recognition, interest bearing loans and borrowings are subsequently measured at amortized cost using the effective interest rate method. Contingent consideration and foreign exchange contracts are measured initially at fair value through profit or loss with transaction costs taken directly to the consolidated statement of operations. Subsequently, the fair values are remeasured and gains and losses from changes therein are recognized in the consolidated statement of operations. Derivatives and hedging activities Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. Where the derivative is not designated as a cash-flow hedge, subsequent changes in the fair value are recognized in profit or loss. Such derivatives are classified as a current asset or liability. The group designates certain derivatives as cash flow hedges to hedge particular risks associated with the cash flows of recognized assets and liabilities and highly probable forecast transactions. At inception of the hedge relationship, the Group documents the economic relationship between hedging instruments and hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the cash flows of hedged items. The Group documents its risk management objective and strategy for undertaking its hedge transactions. Currently the Group has only designated cash flow hedges. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the cash flow hedge reserve within equity. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss. When a hedging instrument matures, any gains or losses held in the cash flow hedge reserve are recycled to the statement of operations or inventory on the balance sheet when the related hedged item is recognized in the statement of operations or inventory on the balance sheet. If a hedge no longer meets the criteria for hedge accounting, or the forecast transaction is no longer likely to occur, the cumulative gain or loss reported in equity is immediately reclassified to profit or loss. m) The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s, CGU’s or group of CGU’s fair value less costs of disposal and its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less costs of disposal, recent market transactions are taken into account. The Group bases its impairment calculation on detailed budgets which are prepared separately for each of the Group’s CGUs to which the individual assets are allocated. These budgets and forecast calculations cover a period of five to ten years, according to the nature and maturity of each CGU. Impairment losses of continuing operations, are recognized in the statement of operations in expense categories consistent with the function of the impaired asset. For assets excluding goodwill, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, the Group estimates the asset’s or CGU’s recoverable amount. Goodwill and intangible assets are tested for impairment annually as at December 31 and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. When the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods. n) Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. o) Employees (including senior executives) of the Group receive remuneration in the form of share based payments, whereby employees render services as consideration. The consideration is either equity or cash settled depending on the scheme. Equity-settled transactions The cost of equity-settled transactions is determined by the fair value at the date when the grant is made using an appropriate valuation model. That cost is recognized, together with a corresponding increase in other capital reserves in equity, over the period in which the performance and/or service conditions are fulfilled in employee benefits expense. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The statement of operations expense or credit for a period represents the movement in cumulative expense recognized as at the beginning and end of that period. No expense is recognized for awards that do not ultimately vest. Cash-settled transactions For cash-settled share based payments, a liability is recognized for the goods or services acquired, measured initially at the fair value of the liability. At each balance sheet date until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with any changes in fair value recognized in profit or loss for the year. Employment related taxes Where the Group has an obligation to settle employment related taxes on share based payments received by employees, these are provided for based on the intrinsic value of the vested share options at the end of the reporting period. p) For the purpose of presentation in the statement of cash flows, cash and cash equivalents includes cash on hand, deposits held at call with financial institutions, other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and bank overdrafts. The Group has classified amounts held in money market funds as cash equivalents because those funds are short term in nature, highly liquid, readily convertible to known amounts of cash, and subject to an insignificant risk of changes in value. The Group has determined this classification is appropriate because each of these EU-regulated funds have the highest credit rating available. 2.4. Amendments to IFRSs that are mandatorily effective for the current year In the year ended December 31, 2019, the Group has applied the below amendments to IFRS’s issued by the IASB that are mandatorily effective for an accounting period that began on or after January 1, 2019. IFRS 16 Leases The Group has adopted IFRS 16 in accordance with the modified retrospective transitional approach in the current year. The application of the standard has resulted in almost all leases being recognized on the balance sheet as the distinction between operating and finance leases has been removed. Under the new standard, a right of use asset and a financial liability to pay

Disclosure Of Accounting Judgments And Estimates [Abstract]
Critical accounting judgments and key sources of estimation uncertainty	3. Critical accounting judgments and key sources of estimation uncertainty Certain accounting policies are considered to be critical to the Group. An accounting policy is considered to be critical if, in the Directors’ judgement, its selection or application materially affects the Group’s financial position or results. The application of the Group’s accounting policies also requires the use of estimates and assumptions that affect the Group’s financial position or results. Below is a summary of areas in which estimation is applied primarily in the context of applying critical accounting judgements. Critical judgements in applying group accounting policies Intangible assets – development costs capitalization Assessing whether assets meet the required criteria for initial capitalization requires judgement. This requires an assessment of the expected future benefits from the projects to be capitalized, technical feasibility and commercial viability. In particular, internally generated intangible assets must be assessed during the development phase to identify whether the Group has the ability and intention to complete the development successfully. Determining the costs of assets to be capitalized also requires judgement. Specifically, judgement and estimation is required in determining the directly attributable costs to be allocated to the asset to enable the asset to be capable of operating in the manner intended by management. Recognition of a deferred tax asset The Group has accumulated significant unutilized trading tax losses (Note 27). A deferred tax asset in respect of these losses can only be recognized when it is probable that future taxable profits will be available to utilize these against. The Group reviews this assessment on an annual basis Farfetch UK Limited functional currency change – date of change As disclosed on Note 2.1, in January 2019 the functional currency of Farfetch UK Limited, the Group’s primary trading entity, changed from pound sterling to U.S dollar. While the trigger for the change was based on a factual assessment as described in the aforementioned Note 2.1, the determination of the date of change required judgement given the gradual change in the primary economic and business environment in which Farfetch UK Limited operates. This was driven by the growth of consumers where the Group receives U.S. dollars in settlement, as well as an increase in costs influenced by movements in the U.S dollar, throughout 2018 and crystalizing in Q4 2018. Guidance requires a change in functional currency to be reported as of the date it is determined there has been a change and it is generally accepted practice that the change is made at start of the most recent period. Noting that in accordance with IAS 21:35, when there is a change in an entity’s functional currency, the entity applies the translation procedures applicable to the new functional currency prospectively from the date of the change, management determined to enact this change effectively on January 1, 2019. Key sources of estimation uncertainty Business combinations We use our best estimates and assumptions to accurately assign fair value to the intangible assets acquired at the acquisition date. The estimation is primarily due to the judgmental nature of the inputs to the valuation models used to measure the fair value of these intangible asset, as well as the sensitivity of the respective fair values to the underlying significant assumptions. We use a discounted cash flow method of the income approach to measure the fair value of these intangible assets and use specialists to develop certain estimates and assumptions. The significant estimates and assumptions used are in respect to (i) expected future revenue growth rates; (ii) anticipated operating margins; (iii) the useful lives of the acquired brand names; and (iv) the discount rates to be applied to the estimated future cash flows. During the measurement period, which may be up to one year from the date of acquisition, the Group may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. The Group continues to collect information and reevaluates these estimates and assumptions as deemed reasonable by management. The Group records any adjustments to these estimates and assumptions against goodwill provided they arise within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statement of operations. We also use our best estimates and assumptions to accurately account for the value of put options over non-controlling interests, when applicable: i) a liability is recognized in the accounts when then non-controlling shareholders have a put option over NCI; ii) NCI is recognized at the time of acquisition when it is considered that the risk and rewards associated NCI rests with non-controlling shareholders and not recognized if it is considered that the risks and rewards rest with Farfetch. For details of business combinations, please refer to Note 5. Impairment of non-financial assets Impairment exists when the carrying value of an asset CGU or group of CGU exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs for disposing of the asset. The value in use calculation is based on a discounted cash flow (“DCF”) model. The cash flows are Intangible assets and property, plant and equipment – useful lives The assessment of the useful economic lives and the method of amortizing these assets requires judgement. Depreciation and amortization are charged to the consolidated statement of operations based on the useful economic life selected, which requires an estimation of the period and profile over which the Group expects to consume the future economic benefits embodied in the asset. The Group reviews its useful economic lives at the reporting date.

Commission revenue is recognized on a net basis in the statement of operations because the Group acts as an agent in these arrangements. The Group primarily acts as a commercial intermediary between sellers and end consumers and earns a commission for this service. Revenue in relation to these obligations within Digital Platform Services Revenue which have not been satisfied at the end of the 2019 reporting period is $691,000 (2018: 1,651,000, 2017: $1,067,000). In 2019, $1,651,000 (2018: $1,067,000, 2017: $330,000) of revenue deferred in 2018 (2017, 2016) was recognized as revenue. In first-party sales arrangements, the Group sells its own goods on the platform where the Group is the principal, and therefore related revenues are recognised on a gross basis. Revenue on the sale of these goods is recognised when the goods are received by the end customer. For finished goods that have been ordered on the platform but not yet delivered to the end consumer at the end of the reporting period, revenue is deferred until delivery. At December 31, 2019, these deferred amounts were $1,766,000 (2018: $2,015,000, 2017: $1,135,000), which the Group expects to recognize within 30 days of period end. In 2019, $2,015,000 (2018: $1,135,000, 2017: $741,000) of revenue deferred in 2018 (2017, 2016) was recognized as revenue. Digital Platform Service Revenue also includes fees charged to sellers for other activities, such as packaging, credit card processing, and other transaction processing activities. At checkout, end consumers are charged for delivery, if applicable, in addition to the price of goods in their basket (refer to Digital Platform Fulfilment Revenue below for a discussion of delivery services). The Group is responsible for the collection of cash from end consumers with payment typically taken in advance of completing its performance obligations. In arrangements where the Group acts as an agent, cash collections are remitted net to the sellers generally within two months of collection. Digital Platform Fulfilment Revenue The Group also provides delivery services for products sold on the platform, for which revenues are recognized when the products are delivered to the end consumers. Revenues for delivery services are stated net of promotional incentives and discounts. Digital Platform Fulfilment Revenue also includes fees charged to sellers for the settlement of duties which are recognized concurrently with commissions. As discussed above, the promise with respect to delivery services is satisfied only when the goods are delivered. Within Digital Platform Fulfilment Revenue, where the delivery performance obligation has not been satisfied at the end of the reporting period, revenue of $851,000 (2018: $479,000, 2017: $436,000) has been deferred and is expected to be recognized in under 90 days from the end of the reporting period. The transaction price for this performance obligation is the delivery costs charged to the consumer as described above. In 2019 $479,000 (2018: $436,000, 2017: $407,000) of revenue deferred in 2018 (2017, 2016) was recognized as revenue. As at the end of the reporting period there were receivables from contracts with customers for the amount of $nil. (2018 and 2017: none). Digital Platform Fulfilment Revenue has previously been referred to as Platform Fulfilment Revenue. Further detail can be found in Note 2.3 e) to the consolidated financial statements. Brand Platform Revenue Brand Platform Revenue includes revenue generated by New Guards operations less revenue from New Guards’: (i) owned e-commerce websites, (ii) direct-to-consumer channel via Farfetch marketplaces and (iii) directly operated stores. Sales are made in the form of first-party sales arrangements to wholesalers, and therefore related revenues are recognized on a gross basis. Wholesale revenue is recognized when the goods are transferred to the wholesaler. For finished goods that have been ordered, but not yet delivered to the wholesaler at the end of the reporting period, revenue is deferred until delivery. At December 31, 2019, these deferred amounts were $26,507,000 (2018: $nil). In-store The Group has a single performance obligation in respect to In-Store Revenue, which is the sale of finished goods.

Acquisition-related costs of $557,000 are included in selling, general and administrative expenses. These costs were recorded in the year ending December 31, 2017. Revenue and profit contribution of acquisitions made in 2017 The results of operations for each of the acquisitions have been included in the Group’s consolidated statements of operations since the respective dates of acquisitions. Actual and pro forma revenue and results of operations for the acquisitions have not been presented because they do not have a material impact to the consolidated revenue and results of operations, either individually or in aggregate. Acquisitions in 2018 There were no business combinations in 2018. Acquisitions in 2019 Stadium Goods On January 4, 2019, Farfetch Limited completed the acquisition of 100% of the outstanding shares of Stadium Goods, the sneaker and streetwear marketplace for total consideration of $230,900,000. The Group expects to benefit from Stadium Goods’ brand, access to supply, and a team who have joined the Group, bringing with them a strong passion for, and knowledge of, luxury streetwear, further enhancing the company’s marketplace and stores offering. The consideration payable by the Group was in the form of cash consideration and Farfetch Limited shares. The consideration payable was split as $150,200,000 of cash, and 4,641,554 Class A Ordinary Shares with a value of $80,700,000 based on the Farfetch Limited share price as at the acquisition date. The transaction is accounted for as a business combination under IFRS 3 and the purchase price allocation accounting has been finalized. Of the $80,700,000 share consideration, $52,100,000 includes a service condition for certain members of the Stadium Goods management team remaining with the Group over a four-year period. This does not satisfy the IFRS 3 definition of consideration and will be recognized as an expense in the statement of operations over the four-year service period as a share based payment expense. Therefore, under IFRS 3, the consideration is $178,800,000 consisting of $150,200,000 cash consideration and $28,600,000 share consideration, none of which is contingent on future performance or service conditions. Details of the purchase consideration, the assets acquired and goodwill are as follows (in thousands): 2019 Cash consideration $ 150,200 Ordinary shares issued 28,600 Total purchase consideration $ 178,800 2019 Net cash outflow arising on acquisition Cash and cash equivalent balances acquired $ 1,678 Cash consideration (150,200 ) Net cash outflow $ (148,522 ) The ordinary shares issued are non-cash investing activities. The Group finalized its purchase price allocation in the first quarter 2019. The Group recognized the following assets and liabilities upon acquisition of Stadium Goods (in thousands): 2019 Intangible assets $ 2,049 Brand name 117,300 Tangible assets 319 Right-of-use assets 2,802 Other non-current assets 243 Inventory 541 Net working capital (excluding inventory) (3,642 ) Non-current liabilities (14,465 ) Total net identified assets acquired 105,147 Goodwill 73,653 Net assets acquired $ 178,800 Goodwill consists of expected synergies to be achieved by combining the operations of Stadium Goods with the Group, as well as other intangible assets that do not qualify for separate recognition under IFRS 3. Goodwill is expected to be deductible for tax purposes. No deferred tax has been recognized however on the basis that management did not consider there to be sufficient evidence at the time of the acquisition that suitable taxable profits were expected to arise to support recognition. As the transaction has been treated as an asset purchase for tax purposes, no deferred tax has been recognized in respect of the brand name as there is no difference between the tax base and carrying amount at acquisition as it is expected that the brand name will be deductible for tax purposes. Acquisition-related costs of $3,987,000 were recorded in 2019, and comprised $2,493,000, which are included in selling, general and administrative expenses, and $1,494,000, which are included in the merger relief reserve. Toplife On May 28, 2019, Farfetch (Shanghai) E-commerce Co., Ltd, a wholly owned subsidiary of Farfetch Limited, acquired 100% of the business of Toplife, a luxury e-commerce platform, from JD Group. The transaction is being treated as a business combination. The primary reason for the acquisition was for the Group to leverage the JD App Level 1 Access Button (Farfetch has replaced the Toplife JD Store with level 1 access being a prominent position on JD App’s homepage) to further enhance the Group’s marketplace business. Details of the purchase consideration, the assets acquired, and goodwill are as follows (in thousands): 2019 Cash consideration $ 48,503 Ordinary shares issued - Total purchase consideration $ 48,503 No cash or cash equivalents were acquired. The Group has performed its preliminary purchase price allocation. Owing to the timing and terms of the transaction, the Group is still refining its valuation assessment, mainly on account of TopLife inventory sales and of shutdown costs to be borne by Farfetch, and is expecting these to be finalized in the first quarter of 2020.

Actual and pro forma revenue and results of operations for the acquisitions of Stadium Goods, Curiosity China and Toplife have not been presented because they do not have a material impact to the consolidated revenue and results of operations, either individually or in aggregate. Actual revenue and results of operations for the acquisition of New Guards for the period since acquisition date were $182,989,000 and $23,142,000 respectively. Pro forma revenue and results of operations for the acquisition of New Guards as though the acquisition date had been the beginning of the year is impracticable because of the lack of financial information at the end of the reporting periods as the acquired entity’s reporting periods were misaligned with Farfetch's reporting periods.

Disclosure Of Operating Segments [Abstract]
Segmental and geographical information	6. Segmental and geographical information Segmental information The Group has identified three reportable operating segments. This assessment is based on information reported to the Group’s Chief Operating Decision Maker, which is deemed to be the Chief Executive Officer, for the purpose of assessing segmental performance and resource allocation. Following the acquisition of New Guards, in the fourth quarter of 2019, we realigned our operating segments to reflect the manner in which the business had become organized and how performance had become internally evaluated. Prior to this realignment, we had one reportable operating segment resulting from the aggregation of four operating segments: (1) Farfetch Marketplace, (2) Farfetch Black and White, (3) Farfetch Store of the Future and (4) Browns stores. As of December 31, 2019, we have three reportable operating segments (A) Digital Platform, (B) Brand Platform and (C) In-Store. Historical periods presented in this Annual Report reflect in these three reportable operating segments. There are no intersegment transactions that require elimination. Order Contribution is used to assess the performance and allocate resources between the segments. The results of our three reportable operating segments is as follows (in thousands): 2017 2018 2019 Digital Platform Services Revenue $ 296,350 $ 488,995 $ 701,246 Fulfilment Revenue 74,182 97,794 127,960 Revenue 370,532 586,789 829,206 Less: Cost of revenue (173,951 ) (295,083 ) (457,293 ) Gross profit 196,581 291,706 371,913 Less: Demand generation expense (69,202 ) (97,295 ) (151,350 ) Order contribution $ 127,379 $ 194,411 $ 220,563 2017 2018 2019 Brand Platform Revenue n/a n/a 164,210 Less: Cost of revenue n/a n/a (89,203 ) Gross profit or order contribution $ - $ - $ 75,007 2017 2018 2019 In-Stores: Revenue $ 15,434 $ 15,595 $ 27,621 Less: Cost of revenue (7,249 ) (8,851 ) (14,695 ) Gross profit or order contribution $ 8,185 $ 6,744 $ 12,926 Geographical information The Group believes it is relevant to disclose geographical revenue information on both a supply basis, determined by location of the Farfetch contracting entity, and on a demand basis, determined by location of consumer. The Group’s UK revenue, based on location of the Farfetch contracting entity, was $619,326,000 (2018: $492,495,000, 2017: $335,345,000). The Group’s revenue from external consumers, based on consumer billing location, and information about its segment assets by geographical location are detailed below (in thousands): 2017 2018 2019 Revenue from external consumers Americas $ 111,349 $ 175,060 $ 277,712 Europe, Middle East and Africa 156,507 240,662 377,944 Asia Pacific 118,110 186,662 365,381 Total Revenue $ 385,966 $ 602,384 $ 1,021,037 2018 2019 Non-current assets Americas $ 6,089 $ 506,130 United Kingdom 118,374 214,213 Europe, Middle East and Africa 21,500 796,974 Asia Pacific 6,020 65,232 Total Non-current assets $ 151,983 $ 1,582,549 In 2018, the Group revised its methodology for determining the geographical location of revenue from being based on consumer shipping location to consumer billing location. In addition, the Group previously disclosed first-party sales based on the location of the seller. In 2018, the Group revised this to being based on the consumer billing location which is consistent with third-party based sales. Revenue by geographical location for the year ended December 31, 2017 was also revised to reflect this change in methodology. No single consumer amounted for more than 10% of Group revenues (2018: none, 2017: none).

Therefore, the leases disclosed in the table above as an expense in profit or loss, arise from payments associated with short-term leases and leases of low-value assets, recognized in profit and loss on a straight-line basis. Short-term leases are leases with a lease term of 12 months or less, while low-value assets comprise IT-equipment and small items of office furniture.

The Group has used a tax rate of 19.00% for the 2019 financial year. The Finance Act 2016 has set the CT rate for the 2020 tax year as 17%. In November 2019, the Prime Minister announced that he intended to cancel the future reduction in corporate tax rate from 19% to 17%. This announcement does not constitute substantive enactment and therefore unrecognized deferred taxes at the balance sheet date continue to be tracked at the enacted tax rate of 17%. However, it is possible that the corporation tax rate remains at 19% after 1 April 2020. There is no income tax relating to the components presented within other comprehensive loss.

Amortization of this will commence once they have been brought into use. Development costs relate to capitalized development expenses relating to development of internal software and developments of the Farfetch websites. Additions to goodwill, brands, trademarks & domain names and customer relationships in 2019 arose due to the business combinations described in Note 5, and the incorporation of $1.9 million of brands, trademark and domain names from the acquisition of New Guards. Amortization for all intangible assets is recorded in selling, general and administrative expenses. Goodwill reflects the amount of consideration in excess of the fair value of net assets of business combinations. The Group tests goodwill annually for impairment, or more frequently if there are indications that goodwill might be impaired. Goodwill has been allocated to the following CGUs or group of CGUs. For details regarding additions to goodwill refer to Note 5. The goodwill amounts for each CGU or group of CGU consists of the following at December 31 (in thousands): 2018 2019 CGU Marketplace $ 16,368 $ 130,993 Browns – Platform 19,675 19,015 CuriosityChina - 3,039 New Guards - 188,020 Total Goodwill $ 36,043 $ 341,067 The recoverable amounts of the CGUs are determined from value in use calculations. The key assumptions for the value in use include (i) expected future revenue growth rates, including the terminal growth rate; (ii) anticipated operating margins; and (iii) the discount rates to be applied to the estimated future cash flows The Group prepares cash flow forecasts derived from the most recent financial budgets approved by management for the next five to ten years, according to the nature and maturity of each CGU. The Group believes this period range is appropriate to capture the high growth rates seen in the markets in which our CGUs operate. The key assumptions for the value in use calculations are the long term growth rate applied to year five or ten onwards and the pre-tax discount rates. The Group extrapolates the cash flows in the fifth or tenth year based on an estimated growth rate of 2% (2018: 2%). This rate does not exceed the average long-term growth rate for the relevant markets. The pre-tax discount rate used to discount the forecast cash flows ranges from 7.7% to 11.7% (2018: 9.7% to 11.8%). The pre-tax discount rate applied is derived from a market participant’s estimated weighted average cost of capital.

Presentation Of Leases For Lessee [Abstract]
Right-of-use assets and lease liabilities	17. This note explains the impact of the adoption of IFRS 16 Leases on the Group’s consolidated financial statements and discloses the new accounting policies that have been applied from January 1, 2019. The Group has adopted IFRS 16 retrospectively from January 1, 2019 but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and adjustments arising from the new leasing rules are therefore recognized in the opening balance sheet on January 1, 2019. The Group's leasing activities and how these are accounted for: The Group leases various offices, retail stores and cars. Lease contracts are typically made for fixed periods of 3 to 8 years but may have extension options. Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. Until financial year 2018, leases of property, plant and equipment were classified as either finance or operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease. From January 1, 2019, leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the group. Each lease payment is allocated between the capital borrowed and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis. Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments: - fixed payments (including in-substance fixed payments), less any lease incentives receivable; - variable lease payments that are based on an index or a rate; - amounts expected to be payable by the lessee under residual value guarantees; - the exercise price of a purchase option if the lessee is reasonably certain to exercise that option; and - payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option. Where it can be determined lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions. Right-of-use assets are measured at cost comprising the following: - the initial measurement of the lease liability; - any lease payments made at or before the commencement date less any lease incentives received; - any initial direct costs; and - restoration costs. Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less. Low-value assets comprise IT-equipment and small items of office furniture. Adjustments recognized on adoption of IFRS 16 On adoption of IFRS 16, the Group recognized lease liabilities in relation to leases which had previously been classified as ‘operating leases’ under the principles of IAS 17 Leases. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as of January 1, 2019. The lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 3.8% on average. For leases previously classified as finance leases the Group recognized the carrying amount of the lease asset and lease liability immediately before transition as the carrying amount of the right of use asset and the lease liability at the date of initial application. The measurement principles of IFRS 16 are only applied after that date. See below details (in thousands): 2019 Operating lease commitments disclosed as at December 31, 2018 $ 103,034 Discounted using the lessee’s incremental borrowing rate of at the date of initial application 78,937 Less short-term leases recognized on a straight-line basis as expense (1,552 ) Less Lease committed to at December 31, 2018 but not commenced at January 1, 2019 (8,074 ) Lease liability recognized as at January 1, 2019 69,311 Of which: Current lease liabilities 12,655 Non-current lease liabilities 56,656 Lease liability recognized as at January 1, 2019 $ 69,311 The associated right-of-use assets were measured at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments relating to that lease recognized on the balance sheet as at December 31, 2018. The Group have used the practical expedient in IFRS 16 that allows a lessee to determine whether a right-of-use asset is impaired through performing an IAS 37 onerous lease assessment. There were no onerous lease contracts that would have required an adjustment to the right-of-use assets at the date of initial application. The recognized right-of-use assets & liabilities relate to the following types as at the transition date and December 31, 2019 (in thousands): January 1, 2019 December 31, 2019 Properties $ 67,272 $ 114,618 Vehicles 469 558 Total right-of-use assets $ 67,741 $ 115,176 Properties $ 68,842 $ 118,760 Vehicles 469 558 Total right-of-use liabilities $ 69,311 $ 119,318 In the year ended December 31, 2019, a depreciation charge of $19,564,000 was recognized in relation to the right-of-use assets. In the year ended December 31, 2019, a finance cost of $3,472,000 was recognized in relation to right-of-use liabilities. In year ended December 31, 2019, cash outflow relating to leases was $19,127,000. Additions to right of use assets in the year ended December 31, 2019 was $41,397,000. During the year end December 31,2019, a charge of $9,449,000 was recognized in relation to short-term and low value leases. In applying IFRS 16 for the first time, the Group has used the practical expedients permitted by the standard: - the accounting for operating leases with a remaining lease term of less than 12 months as at January 1,2019 as short-term leases; and - the exclusion of initial direct costs for the measurement of the right-of-use asset at the date of initial application. The Group has also elected not to reassess whether a contract is, or contains, a lease at the date of initial application. Instead, for contracts entered into before the transition date, the Group relied on its assessment made in applying IAS 17 Leases and IFRIC 4 Determining whether an Arrangement contains a Lease.

Based on a detailed analysis the Group has estimated a liability of $3,352,000 (2018: $2,515,000). In estimating the liability the Group has made assumptions which are based on past experience. Assuming the leases are not extended, the Group expects the economic outflows to match the contractual end date of the leases. The leases have an average lease term of seven years with an average of four years remaining. The share based payments employment taxes provision reflects the best estimate of the cost to settle employment related taxes on the Group share based payments based on the most recent share price and the number of share options expected to vest where the Group has an obligation to settle employment related taxes. The Group has estimated a liability of $7,979,000 (2018: $10,947,000).When a share option is exercised, the liability for employment related taxes crystalizes. During 2019, $5,729,000 (2018: $2,182,000) was transferred from provisions to trade and other payables. As at December 31, 2019, nil amounts transferred to trade and other payables were utilized (2018: $nil). We expect the provision to be fully utilized in 9.79 years (2018: 9.54 years) being the weighted average remaining contracted life of options outstanding at year end. It is likely that this provision will be utilized over a shorter period. However, this is dependent on when the option holder exercises which the Group is not in control of.

Disclosure Of Financial Instruments [Abstract]
Financial instruments and financial risk management	30 . Financial instruments and financial risk management The Group manages its capital to ensure that entities in the Group will be able to continue as going concerns. At December 31, 2018 and December 31 2019, the capital structure consisted solely of equity and the Group was not subject to any externally imposed capital requirements. The Group has identified two principal risks being market risk (foreign exchange) and liquidity risk. Details of the significant accounting policies and methods adopted (including the criteria for recognition, the basis of measurement and the bases for recognition of income and expenses) for each class of financial asset, financial liability and equity instrument are disclosed in Note 2. Categories of financial instruments Financial assets (in thousands) Amortized cost Amortized cost 2018 2019 Current Trade and other receivables $ 48,285 $ 154,813 Cash and cash equivalents 1,044,786 322,429 Non-current Other receivables 10,458 12,388 Total $ 1,103,529 $ 489,630 2018 2019 Foreign currency forwards - held at FVTPL $ 255 $ 587 Foreign currency forwards - held as cash flow hedges 436 2,437 Derivative financial assets $ 691 $ 3,024 Financial liabilities (in thousands) Amortized cost Amortized cost 2018 2019 Trade payables $ 96,176 $ 180,270 Other payables 350 11,062 Total $ 96,526 $ 191,332 2018 2019 Foreign currency forwards - held at FVTPL $ - $ 255 Foreign currency forwards - held as cash flow hedges - 5,346 Derivative financial liabilities $ - $ 5,601 Fair value through profit or loss Fair value through profit or loss 2018 2019 Contingent consideration $ - $ 62,386 Total contingent consideration $ - $ 62,386 Financial risk management objectives The Group’s Corporate Treasury function provides services to the business, co-ordinates access to domestic and international financial markets and monitors and manages the financial risks relating to the operations of the Group through internal risk reports which analyze exposures by degree and magnitude of risks. These risks include market risk (including currency risk, interest rate risk and price risk), credit risk, liquidity risk and cash flow interest rate risk. The Group seeks to minimize the effects of these risks, where appropriate, by using derivative financial instruments to hedge these risk exposures. The use of financial derivatives is governed by the Group’s policies approved by the board of directors, which provide written principles on foreign exchange risk, interest rate risk, credit risk and the use of derivatives. The Group does not enter into or trade financial instruments, including derivative financial instruments, for speculative purposes. Market risk The Group’s activities expose it primarily to the financial risk of changes in foreign currency exchange rates (see table below, in thousands). The Group enters into derivative financial instruments to manage its exposure to foreign currency risk. Foreign currency risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates. The Group uses forward currency contracts to hedge its foreign currency risks. Where the criteria for hedge accounting are not met, derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value with movements recorded to the statement of operations. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative. Where all relevant criteria are met, hedge accounting is applied to minimize earnings volatility. Fair value through profit or loss Asset Liability 2018 2019 2018 2019 Forward foreign exchange contracts $ 255 $ 587 $ - $ 255 Cashflow hedges Asset Liability 2018 2019 2018 2019 Forward foreign exchange contracts $ 436 $ 2,437 $ - $ 5,346 Liquidity risk The Group monitors its liquidity risk to maintain a balance between continuity of funding and flexibility. This helps the Group achieve timely fulfilment of its obligations while sustaining the growth of the business. The table below (in thousands) analyses the Group’s financial liabilities into relevant groupings based on the remaining period from the reporting date to the contractual maturity date. Amounts due within 12 months equal their carrying balances, as the impact of discounting is not significant. Less than one year Less than one year 2018 2019 Trade and other payables $ 96,526 $ 191,332 Contingent consideration - 1,118 Total current $ 96,526 $ 192,450 More than one year More than one year 2018 2019 Contingent consideration $ - $ 61,268 Borrowings - - Total non-current $ - $ 61,268 All derivative financial instruments included in trade and other payables have a maturity of less than 12 months. The contingent consideration is the liability associated with the non-controlling interests arising from the transactions with CuriosityChina and Chalhoub. The non-current contingent consideration is comprised of $1.1 million and $60.2 million expected to mature by the end of 2021 and 2022, respectively. See Note 23 for further information. Credit risk Credit risk is the risk that financial loss arises from the failure of a consumer to meet its obligations under a contract. Due to the nature of operations the Group does not have significant exposure to credit risk. The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. The Group applies a loss allowance to trade and other receivables. As at December 31, 2019 all trade and other receivables were considered current being due within 30 days. The expected loss rate the Group applies for trade and other receivables is 0.5%. The expected loss rates are based on the payment profiles of sales over a period of 36 months before December 31, 2019 or January 1, 2019 respectively and the corresponding historical credit losses experienced within this period which were not significant. The historical loss rates are adjusted to reflect current and forward looking information on macroeconomic factors affecting the ability of the consumers to settle the receivables. The Group has identified the GDP and the unemployment rate of the countries in which it sells its goods and services to be the most relevant factors, and accordingly adjusts the historical loss rates based on expected changes in these factors. The majority of the Group’s cash and cash equivalents balance is held in money market funds which are regulated by securities and market authorities. These consist of AAA rated mutual investment funds which are permitted to diversify portfolio investments through high quality debt securities meeting regulatory mandated requirements. As such, the Group is not exposed to any material credit risk in relation to the cash and cash equivalents balance. Capital risk management The Group’s objective when managing capital is to safeguard the Group’s ability to provide returns for members and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. At December 31, 2019, the Group holds restricted cash of $12.5 million (2018: $nil). The Group is not subject to any externally imposed capital requirements. The capital structure is as follows (in thousands): 2018 2019 Total borrowings $ - $ - Less: cash and cash equivalents (1,044,786 ) (322,429 ) Net cash (1,044,786 ) (322,429 ) Total equity 1,128,431 1,337,832 Total $ 83,645 $ 1,015,403 The main purpose of the Group’s financial instruments is to finance the Group’s operations. The main risks from the Group’s financial instruments are currency risk and liquidity risk. The Board reviews and approves policies, which have remained substantially unchanged for the year under review, for managing these risks. Hedge accounting classification and impact The Group designates certain forward foreign exchange contracts as cash flow hedges of forecast foreign currency revenue and costs. During the current year, losses of $7.9m (2018: $nil) were removed from the cash flow hedge reserve. A gain of $0.5m (2018: $nil) was taken to revenue, a loss of $0.2m (2018: $nil) was taken to cost of revenue and a loss of $8.1m (2018: nil) was taken to selling, general and administration expenses. A loss of $0.1m (2018: $nil) was added to inventories in the statement of financial position. The Group uses a qualitative method for assessing hedge effectiveness. The hedge is assessed at inception and throughout the life of the hedge. Effectiveness between the hedged item and hedging instrument is tested by comparing the critical terms of both items and concluding that they are offsetting. Fair value hierarchy The Group recognizes the following financial instruments at fair value: • derivative financial instruments, measured using a Level 2 valuation method; and • contingent consideration, measured using a Level 2 valuation method. In the year ended December 31, 2019, all contingent consideration was settled through the issue of shares. The valuation of contingent consideration was based upon the share price of the Group, which is deemed to be observable. There have been no significant changes in the measurement and valuation techniques, or transfers between levels of the fair value hierarchy used in measuring the fair value of financial instruments, or changes in the classification of financial assets and liabilities. The carrying amount of the Group’s financial assets and financial liabilities are the same as their fair value. Contingent consideration The Group records contingent consideration arrangements at fair value based on the present-value of probability-weighted future cash flows related to the performance criteria and the fair value of our common stock at each reporting date. We classify our contingent consideration liability in connection with investment related activity in 2019 within Level 2 of the fair value hierarchy as the lowest level inputs used to develop the estimated fair value are directly or indirectly observable. The estimated fair value of our contingent consideration liability is based on the present-value of probability-weighted future cash flows related to the performance criteria and the fair value of our common stock at each reporting date. Changes in the fair value of the contingent consideration liability subsequent to the acquisition date, such as changes in the probability assessment and the fair value of our common stock, are recognized in earnings in the period when the change in the estimated fair value occurs. During the year ended December 31, 2019, we recognized initially contingent consideration liabilities of $105,586,000. Subsequently we recognized a decrease in the fair value of our contingent consideration liability of $43,200,000, in gains on items held at fair value in our consolidated statement of operations, primarily due to a decrease in the fair value of our common stock. Financial instruments sensitivity analysis In managing currency risk the Group aims to reduce the impact of short term fluctuations on its earnings. At the end of each reporting year, the effects of hypothetical changes in currency are as follows. Foreign exchange rate sensitivity analysis The table below (in thousands) shows the Group’s sensitivity to U.S. dollars strengthening/weakening by 10%: Increase/ (decrease) in profit or loss Increase/ (decrease) in profit or loss 2018 2019 10% appreciation of United States dollars $ 29,169 $ (21,661 ) 10% depreciation of United States dollars $ (35,651 ) $ 26,475 This analysis reflects the impact on the statement of operations due to financial assets and liabilities held at the balance sheet date and is based on foreign currency exchange rate variances that the Group considers to be reasonably possible at the end of the reporting year. The analysis assumes that all other variables, in particular interest rates, remain constant.

In 2019, as part of the New Guard’s acquisition, we recorded a $12,139,000 liability for equity settled awards. b. Cash settled Since 2016 the Group issues to certain employees share appreciation rights (“SAR”s) that require the Group to pay the intrinsic value of the SAR to the employee at the date of exercise. The Group has recorded liabilities of $3,120,000 in 2019 ($15,342,000 in 2018) through the grant of 137,000 SARs (2018: 769,000 SARs). The fair value of the SARs is determined by using the Black Scholes model using the same assumptions noted in the above table for the Group’s equity-settled share based payments. The fair value of the liability is then reassessed at each reporting date. Included in the 2019 expense of $10,675,000 (2018: $10,355,000, 2017: $3,807,000), is a revaluation loss of $2,161,000 (2018: gain of $6,079,000).

Basis of preparation	2.1. The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The Directors have made an assessment of the Group’s ability to continue in operational existence for the foreseeable future and are satisfied that it is appropriate to continue to adopt the going concern basis of accounting in preparing the consolidated financial statements. The consolidated financial statements have been prepared under the historical cost convention unless otherwise stated. The consolidated financial statements are presented in United States dollars (“U.S. dollars” or “USD” or “$”). All values are rounded to the nearest thousand dollars, except where indicated. The tables in these notes are shown in USD thousands, except where indicated. In January 2019, the functional currency of Farfetch UK Limited, the Group’s primary trading entity, changed from pound sterling to U.S dollars. This was a result of a gradual change in the primary economic environment in which Farfetch UK Limited operates driven by the growth of consumers where the Group receives U.S. dollars in settlement. This is combined with an increase in costs influenced by movements in the U.S dollar. The Group’s corporate treasury function continually monitors the Group’s exposure to foreign currency movements. Farfetch UK Limited is exposed to movements in several key currencies including the U.S dollar, euro and pound sterling. Following review of Farfetch UK Limited’s expected receipts and expenses, the Group determined that U.S dollars had become the dominant currency from January 2019. As a result this has triggered a change in functional currency. Effective January 1, 2019, we adopted the requirements of IFRS 16, Leases, (“IFRS 16”) as discussed below. The consolidated financial statements provide comparative information in respect of the previous periods.
Basis of consolidation	2.2. The consolidated financial statements comprise the consolidated financial statements of the Group and its subsidiaries. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including: • The contractual arrangement with the other vote holders of the investee; • Rights arising from other contractual arrangements; and • The Group’s voting rights and potential voting rights. The Group re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Group gains control until the date control ceases. Profit or loss and each component of other comprehensive income (“OCI”) are attributed to the equity holders of the parent of the Group and to the non-controlling interests. When necessary, adjustments are made to the consolidated financial statements of subsidiaries to bring their accounting policies into line with the Group’s accounting policies. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation. A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction.
Business combinations and goodwill	a) Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred measured at acquisition date fair value and the amount of any non-controlling interests in the acquiree. For each business combination, the Group measures the non-controlling interests in the acquiree at the proportionate share of the acquiree’s identifiable net assets. When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. Any contingent consideration to be transferred by the Group is recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and is measured at fair value with changes in fair value recognized in profit or loss. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interests over the net identifiable assets acquired and liabilities assumed which are measured at fair value at the date of acquisition. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units (“CGU”) that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Annual impairment testing is performed at every reporting date being December 31. Refer to Note 2.3m) for the Group’s policy on the impairment of non-financial assets. Business combinations We use our best estimates and assumptions to accurately assign fair value to the intangible assets acquired at the acquisition date. The estimation is primarily due to the judgmental nature of the inputs to the valuation models used to measure the fair value of these intangible asset, as well as the sensitivity of the respective fair values to the underlying significant assumptions. We use a discounted cash flow method of the income approach to measure the fair value of these intangible assets and use specialists to develop certain estimates and assumptions. The significant estimates and assumptions used are in respect to (i) expected future revenue growth rates; (ii) anticipated operating margins; (iii) the useful lives of the acquired brand names; and (iv) the discount rates to be applied to the estimated future cash flows. During the measurement period, which may be up to one year from the date of acquisition, the Group may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. The Group continues to collect information and reevaluates these estimates and assumptions as deemed reasonable by management. The Group records any adjustments to these estimates and assumptions against goodwill provided they arise within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statement of operations. We also use our best estimates and assumptions to accurately account for the value of put options over non-controlling interests, when applicable: i) a liability is recognized in the accounts when then non-controlling shareholders have a put option over NCI; ii) NCI is recognized at the time of acquisition when it is considered that the risk and rewards associated NCI rests with non-controlling shareholders and not recognized if it is considered that the risks and rewards rest with Farfetch. For details of business combinations, please refer to Note 5.
Investment in associates	b) The Group recognizes an associate when the Group has a significant influence over that entity. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies. The Group’s investment in its associate, Farfetch Finance Limited, is accounted for using the equity method. Under the equity method of accounting, the investments are initially recognized at cost and adjusted thereafter to recognize the Group’s share of the post-acquisition profits or losses of the investee in profit or loss, and the Group’s share of movements in other comprehensive income of the investee in other comprehensive income.
Current versus non-current classification	c) The Group presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset is current when it is: • Expected to be realized or intended to be sold or consumed in the normal operating cycle; • Held primarily for the purpose of trading; • Expected to be realized within twelve months after the reporting period; or • Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as non-current. A liability is current when: • It is expected to be settled in the normal operating cycle; • It is held primarily for the purpose of trading; • It is due to be settled within twelve months after the reporting period; or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period. The Group classifies all other liabilities as non-current.
Fair value measurement	d) This section outlines the Group policies applicable to financial instruments that are recognized and measured at fair value in the consolidated financial statements. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • In the principal market for the asset or liability; or • In the absence of a principal market, in the most advantageous market for the asset or liability. The principal or the most advantageous market must be accessible by the Group. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data is available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: • Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities • Level 2: Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable • Level 3: Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable For assets and liabilities that are recognized in the consolidated financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.
Revenue recognition	e) Revenue is recognized in accordance with the five-step model under IFRS 15, which was early adopted by the Group on January 1, 2017 on a fully retrospective basis: 1. identifying the contracts with customers; 2. identifying the separate performance obligations; 3. determining the transaction price; 4. allocating the transaction price to the separate performance obligations; and 5. recognizing revenue when each performance obligation is satisfied. Retailing of goods Revenue, where the Group acts as a principal, is recognized when the performance obligation is satisfied which is when the goods are received by the consumer. Included within sales of goods is a provision for expected returns, discounts and rebates. Where these are not known, the Group uses historical data and patterns to calculate an estimate. Rendering of services The Group primarily acts as a commercial intermediary between sellers, being the brands and retailers, and end consumers and earns a commission for this service. For these arrangements, the sellers determine the transaction price of the goods sold on the website, being the purchase price paid by the consumer, with the Group acting as an agent for the sellers and the related revenue is recognized on a net basis. The Group also charges fees to sellers for activities related to providing this service, such as packaging, credit card processing, settlement of duties, and other transaction processing activities. These activities are not considered separate promises to the consumer, and the related fees are therefore recognized concurrently with commissions at the time the performance obligation to facilitate the transaction between the seller and end consumer is satisfied, which is when the goods are dispatched to the end consumer by the seller. A provision is made for commissions that would be refunded if the end consumer returns the goods, and the Group uses historical data and patterns to estimate its return provision. There are no significant payment terms with the Group taking payment in full from the consumer’s chosen payment method at the time the goods are dispatched by the seller. The Group also provides delivery services to end consumers, with the Group setting the transaction price, for goods purchased on its platform. For these services, the Group acts as the principal and recognizes as revenue amounts charged to end consumers net of any promotional incentives and discounts. Revenue for these services is recognized on delivery of goods to the end consumer, which represents the point in time at which the Group’s performance obligation is satisfied. No provision for returns is made as delivery revenue is not subject to refund. Promotional incentives, which include basket promo-code discounts, may periodically be offered to end consumers. These are treated as a deduction to revenue. Cash is collected by the Group from the end consumer using payment service providers. Within two months of the transactions, this is remitted to the relevant seller (net of commission and recoveries). Such amounts are presented within trade and other payables, unless the relevant seller is in a net receivable position and is therefore classified within trade and other receivables.
Current and deferred tax	f) Current tax is the expected tax payable based on the taxable profit for the period, and the tax laws that have been enacted or substantively enacted by the reporting date. 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 recognized on differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit, and is accounted for using the balance sheet liability method. Deferred tax liabilities are generally recognized for all taxable temporary differences and deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit. Current and deferred tax is charged or credited in the statement of operations, except when it relates to items charged or credited directly to equity, in which case the current or deferred tax is also recognized directly in equity. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates and in accordance with laws that are expected to apply in the period/jurisdiction when/where the liability is settled, or the asset is realized. Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities and where there is an intention to settle the balances on a net basis.
Foreign currency translation	g) The Group’s consolidated financial statements are presented in U.S. dollars. For each entity the Group determines the functional currency and items included in the consolidated financial statements of each entity are measured using that functional currency. The functional currency of the Company is U.S. dollars. h) Transactions in foreign currencies are initially recorded by the Group’s entities at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rates of exchange at the reporting date. Differences arising on settlement or translation of monetary items are recognized in profit or loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined. The gain or loss arising on translation of non-monetary items measured at fair value is treated in line with the recognition of the gain or loss on the change in fair value of the item (i.e., translation differences on items whose fair value gain or loss is recognized in OCI or profit or loss are also recognized in OCI or profit or loss, respectively). On consolidation, the assets and liabilities of foreign operations are translated into U.S. dollars at the rate of exchange prevailing at the reporting date and their statements of profit or loss are translated at average exchange rates. The exchange differences arising on translation for consolidation are recognized in OCI.
Property, plant and equipment	i) Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. All repair and maintenance costs are recognized in profit or loss as incurred. Items of property, plant and equipment are depreciated with an expense recognized in depreciation and amortization expense on a straight-line basis over their useful life. The useful lives of these items are assessed as follows: Leasehold improvements Shorter of the life of the lease or useful life Fixtures and fittings Three to ten years Motor vehicles Four to eight years Plant, machinery and equipment Leased plant and equipment Three to ten years Three to eight years The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate. The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.
Intangible assets	j) Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Internally generated intangibles, excluding capitalized development costs, are not capitalized and the related expenditure is reflected in profit or loss in the period in which the expenditure is incurred. The useful lives of intangible assets are assessed as either finite or indefinite. Intangible assets with finite lives are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of operations in the expense category that is consistent with the function of the intangible assets. Other than goodwill, there are no intangible assets with indefinite useful lives. Goodwill is not amortized but is reviewed for impairment at least annually. For the purpose of impairment testing, goodwill is allocated to the relevant CGUs which are tested for impairment annually. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro-rata on the basis of the carrying amount of each asset in the unit. On disposal of a cash-generating unit, the attributable amount of goodwill is included in the determination of the profit or loss on disposal. Refer to Note 2.3m) for the Group’s policy on the impairment of non-financial assets. Research and development costs Research costs are expensed as incurred. Development expenditures on an individual project are recognized as an intangible asset when the Group can demonstrate: • The technical feasibility of completing the intangible asset so that the asset will be available for use or sale; • Its intention to complete and its ability and intention to use or sell the asset; • How the asset will generate future economic benefits; • The availability of resources to complete the asset; and • The ability to measure reliably the expenditure during development. Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortization and accumulated impairment losses. Amortization of the asset begins when development is complete and the asset is available for use. It is amortized over the period of expected future benefit. Amortization is recorded in administrative expenses. Development intangible assets under the course of construction are tested for impairment annually or more frequently if events or changes in circumstance indicate that they might be impaired. Once placed into service the asset is tested for impairment whenever events or changes in circumstance indicate that the carrying amount may not be recoverable. Subsequent costs Subsequent costs are only capitalized when there is an increase in the anticipated future economic benefit attributable to the assets in question. All other subsequent costs are recorded in the statement of operations for the year in which they are incurred. Amortization Amortization is charged to depreciation and amortization expense on a straight-line basis over the estimated useful life of the intangible assets, from the time that the assets are available for use. The useful lives of these items are assessed as follows: Development costs Three years Brand, trademarks & domain names Five to sixteen years Customer relationships Three to five years
Inventories	k) Inventories are carried at the lower of cost and the net realizable value based on market performance, including the relative ancillary selling costs. The cost of inventories, calculated according to the weighted average cost method for each category of goods, includes purchase costs and costs incurred to bring the inventories to their present location and condition. In order to represent the value of inventories appropriately in the statement of financial position, and to take into account impairment losses due to obsolete materials and slow inventory movement, obsolescence provisions have been directly deducted from the carrying amount of the inventories.
Financial instruments-initial recognition and subsequent measurement	l) A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets The Groups financial assets comprise cash and cash equivalents, receivables and derivative financial instruments. Derivative financial instruments are comprised of forward exchange contracts, which are measured at fair value through profit or loss, unless they are formally designated and measured as cash flow hedges. Trade receivables are generally accounted for at amortized cost. The Group assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized cost. Financial assets through profit or loss are measured initially at fair value with transaction costs taken directly to the consolidated statement of operations. Subsequently, the financial assets are remeasured, and gains and losses are recognized in the consolidated statement of operations. Financial liabilities The Group’s financial liabilities comprise trade and other payables, interest bearing loans and borrowings, contingent consideration and foreign exchange contracts. Trade and other payables are held at amortized cost. All interest bearing loans and borrowings are initially recognized at fair value net of issue costs associated with the borrowing. After initial recognition, interest bearing loans and borrowings are subsequently measured at amortized cost using the effective interest rate method. Contingent consideration and foreign exchange contracts are measured initially at fair value through profit or loss with transaction costs taken directly to the consolidated statement of operations. Subsequently, the fair values are remeasured and gains and losses from changes therein are recognized in the consolidated statement of operations. Derivatives and hedging activities Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. Where the derivative is not designated as a cash-flow hedge, subsequent changes in the fair value are recognized in profit or loss. Such derivatives are classified as a current asset or liability. The group designates certain derivatives as cash flow hedges to hedge particular risks associated with the cash flows of recognized assets and liabilities and highly probable forecast transactions. At inception of the hedge relationship, the Group documents the economic relationship between hedging instruments and hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the cash flows of hedged items. The Group documents its risk management objective and strategy for undertaking its hedge transactions. Currently the Group has only designated cash flow hedges. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the cash flow hedge reserve within equity. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss. When a hedging instrument matures, any gains or losses held in the cash flow hedge reserve are recycled to the statement of operations or inventory on the balance sheet when the related hedged item is recognized in the statement of operations or inventory on the balance sheet. If a hedge no longer meets the criteria for hedge accounting, or the forecast transaction is no longer likely to occur, the cumulative gain or loss reported in equity is immediately reclassified to profit or loss.
Impairment of non-financial assets	m) The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s, CGU’s or group of CGU’s fair value less costs of disposal and its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less costs of disposal, recent market transactions are taken into account. The Group bases its impairment calculation on detailed budgets which are prepared separately for each of the Group’s CGUs to which the individual assets are allocated. These budgets and forecast calculations cover a period of five to ten years, according to the nature and maturity of each CGU. Impairment losses of continuing operations, are recognized in the statement of operations in expense categories consistent with the function of the impaired asset. For assets excluding goodwill, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, the Group estimates the asset’s or CGU’s recoverable amount. Goodwill and intangible assets are tested for impairment annually as at December 31 and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. When the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods. Impairment of non-financial assets Impairment exists when the carrying value of an asset CGU or group of CGU exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs for disposing of the asset. The value in use calculation is based on a discounted cash flow (“DCF”) model. The cash flows are
Provisions	n) Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.
Share-based payments	o) Employees (including senior executives) of the Group receive remuneration in the form of share based payments, whereby employees render services as consideration. The consideration is either equity or cash settled depending on the scheme. Equity-settled transactions The cost of equity-settled transactions is determined by the fair value at the date when the grant is made using an appropriate valuation model. That cost is recognized, together with a corresponding increase in other capital reserves in equity, over the period in which the performance and/or service conditions are fulfilled in employee benefits expense. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The statement of operations expense or credit for a period represents the movement in cumulative expense recognized as at the beginning and end of that period. No expense is recognized for awards that do not ultimately vest. Cash-settled transactions For cash-settled share based payments, a liability is recognized for the goods or services acquired, measured initially at the fair value of the liability. At each balance sheet date until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with any changes in fair value recognized in profit or loss for the year. Employment related taxes Where the Group has an obligation to settle employment related taxes on share based payments received by employees, these are provided for based on the intrinsic value of the vested share options at the end of the reporting period.
Cash and cash equivalents	p) For the purpose of presentation in the statement of cash flows, cash and cash equivalents includes cash on hand, deposits held at call with financial institutions, other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and bank overdrafts. The Group has classified amounts held in money market funds as cash equivalents because those funds are short term in nature, highly liquid, readily convertible to known amounts of cash, and subject to an insignificant risk of changes in value. The Group has determined this classification is appropriate because each of these EU-regulated funds have the highest credit rating available.
Changes in accounting policies and disclosures	2.4. Amendments to IFRSs that are mandatorily effective for the current year In the year ended December 31, 2019, the Group has applied the below amendments to IFRS’s issued by the IASB that are mandatorily effective for an accounting period that began on or after January 1, 2019. IFRS 16 Leases The Group has adopted IFRS 16 in accordance with the modified retrospective transitional approach in the current year. The application of the standard has resulted in almost all leases being recognized on the balance sheet as the distinction between operating and finance leases has been removed. Under the new standard, a right of use asset and a financial liability to pay lease rentals are recognized. The only exceptions are short-term and low-value leases in accordance with the practical expedient allowed under the standard. For more information, see Note 17. New and revised IFRSs in issue but not yet effective At the date of authorization of these consolidated financial statements, the Group has not applied the following new and revised IFRSs that have been issued but are not yet effective: IFRS 3 Business Combinations (effective January 1, 2020) ‘Definition of a Business (Amendments to IFRS 3)’ clarifies the definition and application guidance for when an entity assesses whether it has acquired a business or a group of assets. The amendments are effective for business combinations for which the acquisition date is on or after the beginning of the first reporting period beginning on or after January 1, 2020.
Intangible assets—development costs	Intangible assets – development costs capitalization Assessing whether assets meet the required criteria for initial capitalization requires judgement. This requires an assessment of the expected future benefits from the projects to be capitalized, technical feasibility and commercial viability. In particular, internally generated intangible assets must be assessed during the development phase to identify whether the Group has the ability and intention to complete the development successfully. Determining the costs of assets to be capitalized also requires judgement. Specifically, judgement and estimation is required in determining the directly attributable costs to be allocated to the asset to enable the asset to be capable of operating in the manner intended by management.
Recognition of a deferred tax asset	Recognition of a deferred tax asset The Group has accumulated significant unutilized trading tax losses (Note 27). A deferred tax asset in respect of these losses can only be recognized when it is probable that future taxable profits will be available to utilize these against. The Group reviews this assessment on an annual basis
Farfetch UK Limited functional currency change – date of change	Farfetch UK Limited functional currency change – date of change As disclosed on Note 2.1, in January 2019 the functional currency of Farfetch UK Limited, the Group’s primary trading entity, changed from pound sterling to U.S dollar. While the trigger for the change was based on a factual assessment as described in the aforementioned Note 2.1, the determination of the date of change required judgement given the gradual change in the primary economic and business environment in which Farfetch UK Limited operates. This was driven by the growth of consumers where the Group receives U.S. dollars in settlement, as well as an increase in costs influenced by movements in the U.S dollar, throughout 2018 and crystalizing in Q4 2018. Guidance requires a change in functional currency to be reported as of the date it is determined there has been a change and it is generally accepted practice that the change is made at start of the most recent period. Noting that in accordance with IAS 21:35, when there is a change in an entity’s functional currency, the entity applies the translation procedures applicable to the new functional currency prospectively from the date of the change, management determined to enact this change effectively on January 1, 2019.
Intangible assets and property, plant and equipment – useful lives	Intangible assets and property, plant and equipment – useful lives The assessment of the useful economic lives and the method of amortizing these assets requires judgement. Depreciation and amortization are charged to the consolidated statement of operations based on the useful economic life selected, which requires an estimation of the period and profile over which the Group expects to consume the future economic benefits embodied in the asset. The Group reviews its useful economic lives at the reporting date.
