6. 6 AASB Key Decisions Early adoption BIG BANG approach Piecemeal adoption is prohibited except for: AASB 1020 “Income Taxes” Share Based payments

7. 7 Financial Instruments IASB objective: Recognition and measurement of all risks associated with financial instruments, i.e. interest rate, FX, credit risk Outcome: Prescriptive accounting rules based on designation of instrument. All derivatives on balance sheet. No new risks: Australian banks already manage and report the risks addressed by this standard

8. 8 Four categories of financial instruments are identified, based on intention 1. Trading - Valuation method - fair value - Treatment consistent with current practice 2. Loans originated - Valuation method - cost - Most lending assets (including Interbank Receivables) will quality as this category - Treatment consistent with current practice Financial Instruments (continued)

9. 9 3. Held to maturity - Valuation method - cost - Held to maturity have strict criteria to qualify. No sales, no hedging 4. Available for sale - “Available for sale” is a new category - Valuation method - fair value - Allows flexibility to sell assets - Movements in value transferred to new Equity Reserve - Profits on sale transferred from reserve to profit - Hedging permitted

10. 10 Hedges/Derivatives All hedges are fair valued and brought on balance sheet All hedges must be dealt with external market Two types of hedges defined, with different accounting implications 1. Fair Value Hedges (fixed rates hedged into floating) - FV both derivative and hedged item - Correlation of hedges to be measured at least six monthly (80-125% effectiveness range) - Ineffective portion of hedge to P&L

11. 11 Hedges/Derivatives (continued) 2. Cash Flow Hedges (floating rates hedged into fixed) - FV derivatives but not underlying instrument - FV changes taken to Equity Reserve, then recycled to P&L when hedged item impacts P&L - Ineffective portion of hedge to P&L

12. 12 Equity Rules regarding definition of equity are more rigid - must be able to avoid redemption to be equity Less scope for hybrid instruments. Potential for technical breaches of debt covenants by some corporates APRA treatment not yet defined

13. 13 Issues to be Addressed Available for Sale category “Trading” option Cash flow hedges easier to identify and maintain effectiveness Fair value hedges used where high degree of correlation ‘Macro hedging’ now permitted Prepayment risk causes hedge ineffectiveness

14. 14 Other Financial Instrument Issues Effective yield includes capitalised external costs Derecognition of assets - securitisation Loan impairment provisions Embedded derivatives, e.g. debt instrument return linked to ASX equity index movement Systems requirements

15. 15 Business Combinations & Intangible Assets Identifiable intangible assets on acquisition, e.g. core deposits, brand names - Finite or indefinite life No amortisation of goodwill Assess goodwill for impairment on “cash generating unit” / segment basis

16. 16 Pension Accounting Defined benefit plans Recognise prepaid pension cost or fund surplus as asset Fluctuations in surplus / deficit taken to profit

17. 17 Insurance Contracts Phase 1- 2005, Phase 2 - 2007 Insurance contract - exposure to significant insurance risk - Apply existing Australian GAAP Unit linked products - no exposure to risk - Apply IAS 39 - investment contracts - Only capitalise external costs or market value business

18. 18 Performance Reporting Early stages of development Greater categorisation of “profit” - Financial - Non-financial All value movements through P&L - e.g. property revaluations Profit before re-measurements Re-measurements - e.g. increases in existing provisions, property revaluations, equity investments
