BC105. Under IAS 39, investments in equity instruments that are classified as available for sale and investments in unquoted equity instruments whose fair value cannot be reliably measured are subject to an impairment assessment. The original IAS 39 did not include guidance about impairment indicators that are specific to investments in equity instruments. Questions were raised about when in practice such investments become impaired.
BC106. The Board agreed that for marketable investments in equity instruments any impairment trigger other than a decline in fair value below cost is likely to be arbitrary to some extent. If markets are reasonably efficient, today's market price is the best estimate of the discounted value of the future market price. However, the Board also concluded that it is important to provide guidance to address the questions raised in practice.
BC107. The revised IAS 39 includes impairment triggers that the Board concluded were reasonable in the case of investments in equity instruments (paragraph 61). They apply in addition to those specified in paragraph 59, which focus on the assessment of impairment in debt instruments.
Incurred versus expected losses
BC108. Some respondents to the Exposure Draft were confused about whether the Exposure Draft reflected an 'incurred loss' model or an 'expected loss' model. Others expressed concern about the extent to which 'future losses' could be recognised as impairment losses. They suggested that losses should be recognised only when they are incurred (ie a deterioration in the credit quality of an asset or a group of assets after their initial recognition). Other respondents favoured the use of an expected loss approach. They suggested that expected future losses should be considered in the determination of the impairment loss for a group of assets even if the credit quality of a group of assets has not deteriorated from original expectations.
BC109. In considering these comments, the Board decided that impairment losses should be recognised only if they have been incurred. The Board reasoned that it was inconsistent with an amortised cost model to recognise impairment on the basis of expected future transactions and events. The Board also decided that guidance should be provided about what 'incurred' means when assessing whether impairment exists in a group of financial assets. The Board was concerned that, in the absence of such guidance, there could be a range of interpretations about when a loss is incurred or what events cause a loss to be incurred in a group of assets.
BC110. Therefore, the Board included guidance in IAS 39 that specifies that for a loss to be incurred, an event that provides objective evidence of impairment must have occurred after the initial recognition of the financial asset, and IAS 39 now identifies types of such events. Possible or expected future trends that may lead to a loss in the future (eg an expectation that unemployment will rise or a recession will occur) do not provide objective evidence of impairment. In addition, the loss event must have a reliably measurable effect on the present value of estimated future cash flows and be supported by current observable data.
Assets assessed individually and found not to be impaired
(paragraphs 59(f) and 64)
BC111. It was not clear in the original IAS 39 whether loans and receivables and some other financial assets, when reviewed for impairment and determined not to be impaired, could or should subsequently be included in the assessment of impairment for a group of financial assets with similar characteristics.
BC112. The Exposure Draft proposed that a loan asset or other financial asset that is measured at amortised cost and has been individually assessed for impairment and found not to be impaired should be included in a collective assessment of impairment. The Exposure Draft also included proposed guidance about how to evaluate impairment inherent in a group of financial assets.
BC113. The comment letters received on the Exposure Draft indicated considerable support for the proposal to include in a collective evaluation of impairment an individually assessed financial asset that is found not to be impaired.
BC114. The Board noted the following arguments in favour of an additional portfolio assessment for individually assessed assets that are found not to be impaired.

(a) Impairment that cannot be identified with an individual loan may be identifiable on a portfolio basis. The Frameworkstates that for a large population of receivables, some degree of non-payment is normally regarded as probable. In that case, an expense representing the expected reduction in economic benefits is recognised (Framework, paragraph 85). For example, a lender may have some concerns about identified loans with similar characteristics, but not have sufficient evidence to conclude that an impairment loss has occurred on any of those loans on the basis of an individual assessment. Experience may indicate that some of those loans are impaired even though an individual assessment may not reveal this. The amount of loss in a large population of items can be estimated on the basis of experience and other factors by weighing all possible outcomes by their associated probabilities.
(b) Some time may elapse between an event that affects the ability of a borrower to repay a loan and actual default of the borrower. For example, if the market forward price for wheat decreases by 10 per cent, experience may indicate that the estimated payments from borrowers that are wheat farmers will decrease by 1 per cent over a one-year period. When the forward price decreases, there may be no objective evidence that any individual wheat farmer will default on an individually significant loan. On a portfolio basis, however, the decrease in the forward price may provide objective evidence that the estimated future cash flows on loans to wheat farmers have decreased by 1 per cent over a one-year period.
(c) Under IAS 39, impairment of loans is measured on the basis of the present value of estimated future cash flows. Estimations of future cash flows may change because of economic factors affecting a group of loans, such as country and industry factors, even if there is no objective evidence of impairment of an individual loan. For example, if unemployment increases by 10 per cent in a quarter in a particular region, the estimated future cash flows from loans to borrowers in that region for the next quarters may have decreased even though no objective evidence of impairment exists that is based on an individual assessment of loans to borrowers in that region. In that case, objective evidence of impairment exists for the group of financial assets, even though it does not exist for an individual asset. A requirement for objective evidence to exist to recognise and measure impairment in individually significant loans might result in delayed recognition of loan impairment that has already occurred.
(d) Accepted accounting practice in some countries is to establish a provision to cover impairment losses that, although not specifically identified to individual assets, are known from experience to exist in a loan portfolio as of the balance sheet date.
(e) If assets that are individually not significant are collectively assessed for impairment and assets that are individually significant are not, assets will not be measured on a consistent basis because impairment losses are more difficult to identify asset by asset.
(f) What is an individually significant loan that is assessed on its own will differ from one entity to another. Thus, identical exposures will be evaluated on different bases (individually or collectively), depending on their significance to the entity holding them. If a collective evaluation were not to be required, an entity that wishes to minimise its recognised impairment losses could elect to assess all loans individually. Requiring a collective assessment of impairment for all exposures judged not to be impaired individually enhances consistency between entities rather than reduces it.

BC115. Arguments against an additional portfolio assessment for individually assessed loans that are found not to be impaired are as follows.
(a) It appears illogical to make an impairment provision on a group of loans that have been assessed for impairment on an individual basis and have been found not to be impaired.
(b) The measurement of impairment should not depend on whether a lender has only one loan or a group of similar loans. If the measurement of impairment is affected by whether the lender has groups of similar loans, identical loans may be measured differently by different lenders. To ensure consistent measurement of identical loans, impairment in individually significant financial assets should be recognised and measured asset by asset.
(c) The Framework specifies that financial statements are prepared on the accrual basis of accounting, according to which the effects of transactions and events are recognised when they occur and are recognised in the financial statements in the periods to which they relate. Financial statements should reflect the outcome of events that took place before the balance sheet date and should not reflect events that have not yet occurred. If an impairment loss cannot be attributed to a specifically identified financial asset or a group of financial assets that are not individually significant, it is questionable whether an event has occurred that justifies the recognition of impairment. Even though the risk of loss may have increased, a loss has not yet materialised.
(d) The Framework, paragraph 94, requires an expense to be recognised only if it can be measured reliably. The process of estimating impairment in a group of loans that have been individually assessed for impairment but found not to be impaired may involve a significant degree of subjectivity. There may be a wide range of reasonable estimates of impairment. In practice, the establishment of general loan loss provisions is sometimes viewed as more of an art than a science. This portfolio approach should be applied only if it is necessary on practical grounds and not to override an assessment made on an individual loan, which must provide a better determination of whether an allowance is necessary.
(e) IAS 39 requires impairment to be measured on a present value basis using the original effective interest rate. Mechanically, it may not be obvious how to do this for a group of loans with similar characteristics that have different effective interest rates. In addition, measurement of impairment in a group of loans based on the present value of estimated cash flows discounted using the original effective interest rate may result in double-counting of losses that were expected on a portfolio basis when the loans were originated because the lender included compensation for those losses in the contractual interest rate charged. As a result, a portfolio assessment of impairment may result in the recognition of a loss almost as soon as a loan is issued. (This question arises also in measuring impairment on a portfolio basis for loans that are not individually assessed for impairment under IAS 39.)

BC116. The Board was persuaded by the arguments in favour of a portfolio assessment for individually assessed assets that are found not to be impaired and decided to confirm that a loan or other financial asset measured at amortised cost that is individually assessed for impairment and found not to be impaired should be included in a group of similar financial assets that are assessed for impairment on a portfolio basis. This is to reflect that, in the light of the law of large numbers, impairment may be evident in a group of assets, but not yet meet the threshold for recognition when any individual asset in that group is assessed. The Board also confirmed that it is important to provide guidance about how to assess impairment on a portfolio basis to introduce discipline into a portfolio assessment. Such guidance promotes consistency in practice and comparability of information across entities. It should also mitigate concerns that collective assessments of impairment should not be used to conceal changes in asset values or as a cushion for potential future losses.
BC117. Some respondents expressed concerns about some of the detailed guidance proposed in the Exposure Draft, such as the guidance about adjusting the discount rate for expected losses. Many entities indicated that they do not have the data and systems necessary to implement the proposed approach. The Board decided to eliminate some of the detailed application guidance (eg whether to make an adjustment of the discount rate for originally expected losses and an illustration of the application of the guidance).
Assets that are assessed individually and found to be impaired
(paragraph 64)
BC118. In making a portfolio assessment of impairment, one issue that arises is whether the collective assessment should include assets that have been individually evaluated and identified as impaired.
BC119. One view is that methods used to estimate impairment losses on a portfolio basis are equally valid whether or not an asset has been specifically identified as impaired. Those who support this view note that the law of large numbers applies equally whether or not an asset has been individually identified as impaired and that a portfolio assessment may enable a more accurate prediction to be made of estimated future cash flows.

BC120. Another view is that there should be no need to complement an individual assessment of impairment for an asset that is specifically identified as impaired by an additional portfolio assessment, because objective evidence of impairment exists on an individual basis and expectations of losses can be incorporated in the measurement of impairment for the individual assets. Double-counting of losses in terms of estimated future cash flows should not be permitted. Moreover, recognition of impairment losses for groups of assets should not be a substitute for the recognition of impairment losses on individual assets.
BC121. The Board decided that assets that are individually assessed for impairment and identified as impaired should be excluded from a portfolio assessment of impairment. Excluding assets that are individually identified as impaired from a portfolio assessment of impairment is consistent with the view that collective evaluation of impairment is an interim step pending the identification of impairment losses on individual assets. A collective evaluation identifies losses that have been incurred on a group basis as of the balance sheet date, but cannot yet be identified with individual assets. As soon as information is available to identify losses on individually impaired assets, those assets are removed from the group that is collectively assessed for impairment.
Grouping of assets that are collectively evaluated for impairment
(paragraphs 64 and AG87)
BC122. The Board considered how assets that are collectively assessed for impairment should be grouped for the purpose of assessing impairment on a portfolio basis. In practice, different methods are conceivable for grouping assets for the purposes of assessing impairment and computing historical and expected loss rates. For example, assets may be grouped on the basis of one or more of the following characteristics:
(a) estimated default probabilities or credit risk grades;
(b) type (for example, mortgage loans or credit card loans);
(c) geographical location;
(d) collateral type;
(e) counterparty type (for example, consumer, commercial or sovereign);
(f) past-due status; and
(g) maturity.
More sophisticated credit risk models or methodologies for estimating expected future cash flows may combine several factors, for example, a credit risk evaluation or grading process that considers asset type, industry, geographical location, collateral type, past-due status, and other relevant characteristics of the assets being evaluated and associated loss data.

BC123. The Board decided that for the purpose of assessing impairment on a portfolio basis, the method employed for grouping assets should, as a minimum, ensure that individual assets are allocated to groups of assets that share similar credit risk characteristics. It also decided to clarify that when assets that are assessed individually and found not to be impaired are grouped with assets with similar credit risk characteristics that are assessed only on a collective basis, the loss probabilities and other loss statistics differ between the two types of asset with the result that a different amount of impairment may be required.
Estimates of future cash flows in groups
(paragraphs AG89-AG92)
BC124. The Board decided that to promote consistency in the estimation of impairment on groups of financial assets that are collectively evaluated for impairment, guidance should be provided about the process for estimating future cash flows in such groups. It identified the following elements as critical to an adequate process:
(a) Historical loss experience should provide the basis for estimating future cash flows in a group of financial assets that are collectively assessed for impairment.
(b) Entities that have no loss experience of their own or insufficient experience should use peer group experience for comparable groups of financial assets.
(c) Historical loss experience should be adjusted, on the basis of observable data, to reflect the effects of current conditions that did not affect the period on which the historical loss experience is based and to remove the effects of conditions in the historical period that do not exist currently.
(d) Changes in estimates of future cash flows should be directionally consistent with changes in underlying observable data.
(e) Estimation methods should be adjusted to reduce differences between estimates of future cash flows and actual cash flows.
Impairment of investments in available-for-sale financial assets
(paragraphs 67-70)

BC125. In the Exposure Draft, the Board proposed that impairment losses on debt and equity instruments classified as available for sale should not be reversed through profit or loss if conditions changed after the recognition of the impairment loss. The Board arrived at this decision because of the difficulties in determining objectively when impairment losses on debt and equity instruments classified as available for sale have been recovered and hence of distinguishing a reversal of an impairment (recognised in profit or loss) from other increases in value (recognised in equity). Accordingly, the Board proposed that any increase in the fair value of an available-for-sale financial asset would be recognised directly in equity even though the entity had previously recognised an impairment loss on that asset. The Board noted that this was consistent with the recognition of changes in the fair value of available-for-sale financial assets directly in equity (see paragraph 55(b)).
BC126. The Board considered the comments received on its proposal to preclude reversals of impairment on available-for-sale financial assets. It concluded that available-for-sale debt instruments and available-for-sale equity instruments should be treated differently.
Reversals of impairment on available-for-sale debt instruments
(paragraph 70)

BC127. For available-for-sale debt instruments, the Board decided that impairment should be reversed through profit or loss when fair value increases and the increase can be objectively related to an event occurring after the loss was recognised.
BC128. The Board noted that (a) other Standards require the reversal of impairment losses if circumstances change (eg IAS 2 Inventories, IAS 16 Property, Plant and Equipment and IAS 38 Intangible Assets); (b) the decision provides consistency with the requirement to reverse impairment losses on loans and receivables, and on assets classified as held to maturity; and (c) reversals of impairment in debt instruments (ie determining an increase in fair value attributable to an improvement in credit standing) are more objectively determinable than those in equity instruments.
Reversals of impairment on available-for-sale equity instruments
(paragraph 69)
BC129. For available-for-sale equity instruments, the Board concluded that if impairment is recognised, and the fair value subsequently increases, the increase in value should be recognised in equity (and not as a reversal of the impairment loss through profit or loss).

BC130. The Board could not find an acceptable way to distinguish reversals of impairment losses from other increases in fair value. Therefore, it decided that precluding reversals of impairment on available-for-sale equity instruments was the only appropriate solution. In its deliberations, the Board considered:
(a) limiting reversals to those cases in which specific facts that caused the original impairment reverse. However, the Board questioned the operationality of applying this approach (ie how to decide whether the same event that caused the impairment caused the reversal).
(b) recognising all changes in fair value below cost as impairments and reversals of impairment through profit or loss, ie all changes in fair value below cost would be recognised in profit or loss, and all changes above cost would be recognised in equity. Although this approach achieves consistency with IAS 16 and IAS 38, and eliminates any subjectivity involved in determining what constitutes impairment or reversal of impairment, the Board noted that it would significantly change the notion of 'available for sale' in practice. The Board believed that introducing such a change to the available-for-sale category was not appropriate at this time.
Hedging

BC131. The Exposure Draft proposed few changes to the hedge accounting guidance in the original IAS 39. The comments on the Exposure Draft raised several issues in the area of hedge accounting suggesting that the Board should consider these issues in the revised IAS 39. The Board's decisions with regard to these issues are presented in the following paragraphs.
Consideration of the Shortcut Method in SFAS 133
BC132. SFAS 133 Accounting for Derivative Instruments and Hedging Activitiesissued by the FASB allows an entity to assume no ineffectiveness in a hedge of interest rate risk using an interest rate swap as the hedging instrument, provided specified criteria are met (the 'shortcut method').
BC133. The original IAS 39 and the Exposure Draft precluded the use of the shortcut method. Many comments received on the Exposure Draft argued that IAS 39 should permit use of the shortcut method. The Board considered the issue in developing the Exposure Draft, and discussed it in the roundtable discussions that were held in the process of finalising IAS 39.
BC134. The Board noted that, if the shortcut method were permitted, an exception would have to be made to the principle in IAS 39 that ineffectiveness in a hedging relationship is measured and recognised in profit or loss. The Board agreed that no exception to this principle should be made, and therefore concluded that IAS 39 should not permit the shortcut method.
BC135. Additionally, IAS 39 permits the hedging of portions of financial assets and financial liabilities in cases when US GAAP does not. The Board noted that under IAS 39 an entity may hedge a portion of a financial instrument (eg interest rate risk or credit risk), and that if the critical terms of the hedging instrument and the hedged item are the same, the entity would, in many cases, recognise no ineffectiveness.
Hedges of Portions of Financial Assets and Financial Liabilities
