FX options make up an element of many companies fx risk management strategies. FX options lock in the certainty of worst case exchange rate outcomes while allowing participation in favourable rate movements. In my experience, companies are often reluctant to write out a cheque for the premium so for many the preferred strategy is collar options. A collar option involves writing, or selling, an fx option simultaneously as buying the fx option in order to reduce premium, often to zero.
After transacting the fx option, the challenge comes for those that are hedge accounting and the requirement to split the valuation of the fx option into time value and intrinsic value. IAS 39 allows the intrinsic value of an fx option to be designated in a hedge relationship and can therefore remain on the balance sheet. The time value of the fx option is recognised through profit or loss.
The intrinsic value of an fx option is the difference between the prevailing market forward rate for the expiry of the fx option versus the strike price. We can use an Australian based exporter to the US as an example. In our example the exporter forward hedged US$1 million of export receipts six months ago (the USD income is due to be received in three months’ time). At the time of hedging the AUD/USD rate was 0.8750 and the nine month forward rate was 0.8580. The company chose to hedge with a nine month zero cost collar (ZCC). Six months’ ago the ZCC might have been as follows:
- Option 1: Bought USD Put / AUD Call at a strike of 0.9000
- Option 2: Sold AUD Put / USD Call expiring at a strike of 0.8000
The intrinsic value of each leg of the collar will be determined by the difference in the forward rate at valuation date versus the strike rates. For option 1, the bought option, if the forward rate is above the strike of 0.9000 then the fx option will have positive intrinsic value i.e. it is “in-the-money”. It is important to note that the intrinsic value of a bought fx option cannot be negative. The purchaser, or holder, of the fx option has all of the rights and would not choose to exercise the fx option if the market rate was below the strike price. They would simply choose to walk away from the fx option, let it expire worthless, and transact at the lower market rate.
For the sold fx option the opposite is true. If the forward rate is below the strike price (less than 0.8000 in our example) then the exporter, as the writer of the option, will be exercised upon and the difference between the market rate and the strike rate will be negative intrinsic value. Intrinsic value of a sold fx option cannot be positive.
The time value of an fx option is the difference between the overall fx option valuation and the intrinsic value. By definition, time value is a function of the time left to the expiry of the fx option. The longer the time to expiry, the higher the time value as there is a greater probability of the fx option being exercised. A purchased fx option begins life with positive time value that decays over time to zero. A sold fx option begins life with negative time value and tends to zero by expiry date.
When hedge accounting for fx options the splitting of intrinsic value (balance sheet) and time value (P&L) does not have to be a time consuming exercise. At Hedgebook we like to make life easy so as part of the FX Options Held Report the valuations are automatically split by intrinsic value and time value. The screen shot below shows the HedgebookPro output using our Aussie exporter example. With the significant weakening of the AUD in the last six months we see the zero intrinsic value of the bought option at a strike of 0.9000 and very little time value as there is little chance of the AUD strengthening to above 0.9000 by the time the option expires by 30 June. The sold fx option has a large, negative intrinsic value. The exporter will be exercised upon and have to convert the US$1 million of receipts at AUD/USD 0.8000 versus a market rate of closer to 0.7600. There is a small amount of negative time value.
HedgebookPro FX Options Held Report
HedgebookPro’s easy to use Treasury Management System calculates fx option valuations split into intrinsic and time value. This simplifies life for those that already use fx options and hedge account, whilst removing obstacles to hedge accounting for those that perceive the accounting requirements as too hard.
The IASB is looking to remove the requirement to split fx option valuations into intrinsic and time components which will simplify the hedge accounting process further, however, currently this appears to be a 2018 story, unless companies choose to adopt early. In the meantime, HedgebookPro provides an easy to use system to ease the pain of hedge accounting fx options.
 Premium received from the sold option offsets the premium paid on the bought option.
