Critical accounting judgements, estimates and assumptions	Note 3. Critical accounting judgements, estimates and assumptions The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the financial statements. Management continually evaluates its judgements and estimates in relation to assets, liabilities, contingent liabilities, revenue and expenses. Management bases its judgements, estimates and assumptions on historical experience and on other various factors, including expectations of future events, management believes to be reasonable under the circumstances. The resulting accounting judgements and estimates will seldom equal the related actual results. The judgements, estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities (refer to the respective notes) within the next financial year are discussed as follows: Research and development expenses The Directors do not consider the development programs to be sufficiently advanced to reliably determine the economic benefits and technical feasibility to justify capitalisation of development costs. These costs have been recognised as an expense when incurred. Research and development expenses relate primarily to the cost of conducting human clinical and pre-clinical trials. Clinical development costs are a significant component of research and development expenses. Estimates have been used in determining the expense liability under certain clinical trial contracts where services have been performed but not yet invoiced. Generally the costs, and therefore estimates, associated with clinical trial contracts are based on the number of patients, drug administration cycles, the type of treatment and the outcome being measured. The length of time before actual amounts can be determined will vary depending on length of the patient cycles and the timing of the invoices by the clinical trial partners. Revenue recognition The consolidated entity applies judgement in determining whether contracts entered into fall within the scope of IFRS 15 Revenue from Contracts with Customers. In doing so, management considers the commercial substance of the transaction and how risks and benefits of the contract accrue to the various parties to the contract. In determining the accounting treatment of the contracts with each customer, management assessed that the contracts were within the scope of IFRS 15 ‘Revenue from Contracts with Customers’. Management has also made the judgement in each case that the grant of the licence and transfer of associated know-how and materials are accounted for as one performance obligation as they are not considered to be distinct; they are highly interrelated and could not provide benefits to the customer independently from each other. Judgements were also made in relation to the transfer of the licence and know-how in each case, and whether this should be recognised over time or a point in time. The point in time has been determined with regard to the point at which the transfer of know-how has substantially been completed and the customer has control of the asset and the ability to direct the use of and receive substantially all of the remaining benefits. Clinical trial expenses The timing of payment for work conducted under clinical trials often bears little relation to the timing of the work effort. Detailed estimates are made to determine the amount of work effort expended during a reporting period in order to determine the appropriate expense to be recognised, with the resulting prepayments or un-invoiced amounts being recognised as a prepayment or an accrual respectively. Share-based payment transactions The consolidated entity measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the date at which they are granted. The fair value is determined by using the Black-Scholes option pricing model taking into account the terms and conditions upon which the instruments were granted. The accounting estimates and assumptions relating to equity-settled share-based payments would have no impact on the carrying amounts of assets and liabilities within the next annual reporting period but may impact profit or loss and equity. Acquisition of intangible assets The consolidated entity has applied judgement in determining the accounting treatment for the acquisition of the License agreement for EVT801. The License agreement has been determined to be a stand alone transaction, independent from any other agreements which have been or may be entered into with Evotec (France) SAS. Management has also made the decision to account for the cost of the asset conferred by the License agreement on the basis of the milestones that are probable of being payable, that is, those for which there is judged to be a probability of greater than 50% that the milestone will be triggered. Contingent consideration Contingent consideration relates to the intangible assets acquired, and the fair value of contingent consideration is dependent on the key assumptions used in accounting for the acquisition of those intangible assets. These assumptions include the probability of milestones occurring, and can also include the anticipated timing of settlement and discount rates used. In the case where contingent consideration is recognised on the basis that the liability is probable of occurring, judgement is used in determining which milestones are considered probable of being triggered. Intangible assets available for use The consolidated entity has exercised judgement in determining that its intangible assets, being license agreements, have a finite life and are available for use once acquired. As the business model is to acquire such assets and then develop them to generate returns from future license transactions or other means, management have determined that the assets are available for use from the time that they are acquired. In each case the prima facie useful life is the remaining life of the patent over the asset, unless other factors over-ride this assessment. Impairment of non-financial assets other than goodwill and other indefinite life intangible assets T he consolidated entity assesses impairment of non-financial assets other than goodwill and other indefinite life intangible assets at each reporting date by evaluating conditions specific to the consolidated entity and to the particular asset that may lead to impairment. Judgement is used to determine whether any indicators of impairment exist, and reference is made to the considerations included in IAS 36 Impairment of Assets in this assessment. If an impairment trigger is found to exist, the recoverable amount of the asset is determined .
