# Provisions

A liability or provision is recognised when there is 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. A provision is made using best estimates of the amount required in settlement and where the effect of the time value of money is material, the amount recognised is the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognised as interest expense. Changes in estimates are reflected in profit or loss in the reporting year they occur.

# 2C. Critical judgements, assumptions and estimation uncertainties

The critical judgements made in the process of applying the accounting policies that have the most significant effect on the amounts recognised in the financial statements and the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting year, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities currently or within the next reporting year are discussed below. These estimates and assumptions are periodically monitored to ensure they incorporate all relevant information available at the date when financial statements are prepared. However, this does not prevent actual figures differing from estimates.

# Net realisable value of inventories:

A review is made on inventory for excess inventory and declines in net realisable value below cost and an allowance is recorded against the inventory balance for any such declines. The review requires management to consider the price protection and other return policies with suppliers and future demand for the products. In any case the realisable value represents the best estimate of the recoverable amount and is based on the acceptable evidence available at the end of the reporting year and inherently involves estimates regarding the future expected realisable value. The usual considerations for determining the amount of allowance or write-down include ageing analysis, technical assessment and subsequent events. In general, such an evaluation process requires significant judgement and materially affects the carrying amount of inventories at the end of the reporting year. Possible changes in these estimates could result in revisions to the stated value of the inventories. The carrying amount of inventories at the end of the reporting year is disclosed in Note 18 on inventories.

# Customer loyalty programme:

The Group operates the (a) ValueClub, Challenger membership scheme and (b) Hachi membership scheme.

The Group allocates the consideration received from the sale of goods to the goods sold and the points issued under its ValueClub Reward Points Customer Loyalty Programme (the “Programme”). The consideration allocated to the points issued is measured at their fair values. Fair values are determined by considering, among others, the following factors: the range of products available to the customers, the prices at which the Group sells the products which can be redeemed and the changing patterns in the redemption rates.

The Group awards Hachi rebates based on a percentage of the product purchased by the customer under its Hachi Dollar Rebate Programme (the “Programme”). The fair value of the rebates is based on the actual amount the customer will be able to utilise to offset against their next purchase. The estimated redemption rate used to determine the carrying value of the rebates based on historical customer’s redemption.

The carrying amount of the Group’s deferred revenue in relation to the Programme at the end of the reporting year is disclosed in Note 25C on other liabilities.

Useful lives of property, plant and equipment:

The estimates for the useful lives and related depreciation charges for property, plant and equipment are based on commercial and other factors which could change significantly as a result of innovations and in response to market conditions. The depreciation charge is increased where useful lives are less than previously estimated lives, or the carrying amounts written off or written down for technically obsolete items or assets that have been abandoned. It is impracticable to disclose the extent of the possible effects. It is reasonably possible, based on existing knowledge, that outcomes within the next reporting year that are different from assumptions could require a material adjustment to the carrying amount of the balances affected. The carrying amount of the specific asset or class of assets at the end of the reporting year affected by the assumption is disclosed in Note 14 on property, plant and equipment.
