(Implementation Guidance on Financial Instruments 143(2),146,156,158)
If the main provisions of the hedging instrument and the hedged item are the same and changes in market
rates or cash flows are expected to perfectly offset, the hedge effectiveness assessment may be abbreviated.
If an initial test shows that the hedge is highly effective and even if a subsequent test shows it to be ineffective, if the range of fluctuations is small and are expected to be temporary, hedge accounting may be continued.
For hedges which fix cash flows, if the cumulative change in the cash flows of the hedging instrument and
the hedged item are highly correlated, they are accepted as effective.
