2. MATERIAL ACCOUNTING POLICY INFORMATION (CONTINUED) Exchange differences arising from the translation of any net investment in foreign entities, and of borrowings and other currency instruments designated as hedges of such investments, are taken to a separate component of equity. The foreign currency reserve is recognised in profit or loss when the foreign operation or net investment is disposed of. Revenue NZ IFRS 15 establishes a five-step model to account for revenue arising from contracts with customers and requires that revenue be recognised at an amount that reflects the consideration to which an entity expects to be entitled in exchange for licensing rights and intellectual property access to a customer. The five-step process is as follows: – identify the contract(s) with a customer; – identify the performance obligations in the contract(s); – determine the transaction price; – allocate the transaction price to the performance obligations in the contract(s); and – recognise revenue when (or as) the performance obligations are satisfied. Licence revenue Licence revenues in connection with licensing of the Group’s intellectual property to customers are recognised as a right to use the entity’s intellectual property as it exists at the point in time at which the licence is granted. This is because the contracts for the licence of intellectual property are distinct and do not require, nor does the customer reasonably expect, that the Group will undertake further activities that significantly affect the intellectual property to which the customer has rights. Although the Group is entitled to sales-based royalties from sales of goods and services to third parties using the intellectual property transferred, these royalty arrangements do not of themselves indicate that the customer would reasonably expect the Group to undertake such activities, and no such activities are undertaken or contracted in practice. Accordingly, the promise to provide rights to the Group’s intellectual property is accounted for as a performance obligation satisfied at a point in time. The following consideration is received in exchange for licences of intellectual property: (i) Up-front payments – These are fixed amounts and are recognised at the point in time when the Group transfers the intellectual property to the customer. (ii) Milestone payments – This is variable consideration that is contingent on the customer reaching certain clinical, regulatory or commercial targets in relation to the intellectual property licenced. Variable consideration is estimated using the most likely amount method, variable consideration is constrained such that amounts are only recognised when it is highly probable that a significant reversal in the amount of cumulative revenue recognised will not occur when the uncertainty associated with the variable consideration (that is, the customer meeting the conditions) is subsequently resolved. Milestone payments that are not in control of the Group, such as regulatory approvals, are not considered highly probable of being achieved until those approvals are received. (iii) Sales-based royalties – Licenses of intellectual property include royalties, which are variable consideration that are based on the sale of products that are produced using the intellectual property. The specific exception to the general requirements of estimating variable consideration for sales or usage-based royalties promised in a licence of intellectual property is applied. The exception requires such revenue to be recognised at the later of when (a) subsequent sales or usage occurs and (b) the performance obligation to which some or all of the sales-based or usage-based royalty has been allocated is satisfied (or partially satisfied). (iv) Rare Disease priority review voucher – This is variable consideration, that is contingent on the customer selling or using a Rare Disease priority review voucher from the Food and Drug Administration (FDA) on approval of an New Drug Application (NDA). Variable consideration is estimated using the most likely amount method, variable consideration is constrained such that amounts are only recognised when it is highly probable that a significant reversal in the amount of cumulative revenue recognised will not occur when the uncertainty associated with the variable consideration (that is, the customer meeting the conditions) is subsequently resolved. Sale or use of the Rare Disease priority review voucher is not in control of the Group, and is not considered highly probable of being achieved until it is sold or used. Interest income Interest income is recognised as it is earned using the effective interest method. Research and development Research costs include direct and directly attributable overhead expenses for drug discovery, research and pre-clinical and clinical trials. Research costs are expensed as incurred. Income tax The income tax expense or benefit for the period is the tax payable on the period’s taxable income or loss using tax rates enacted or substantively enacted at the reporting date, adjusted by changes in deferred tax assets and liabilities attributable to temporary differences and unused tax losses.
