South32 Corporation Limited USD $0.03 Special Dividend – Adjustment implications for ETOs

ASX Notice No. 0930.22.09 dated 1 September 2022 outlined the adjustment method to be applied to ETOs over South32 Limited (ASX Code: S32) due to the USD $0.03 special dividend and an ordinary dividend of USD $0.14 both having an ex-dividend date of 15 September 2022.

Lifting of Exercise Restriction

Please be advised that further to ASX Notice No. 0998.22.09 exercise restriction has been lifted for South32 Limited (S32) Wednesday 14 September 2022.  

Effective Date

The effective date of this adjustment is Thursday, 15 September 2022, when the underlying security commences trading on an ex-dividend basis.

ASX determined that the last cum-dividend VWAP based on trading on ASX markets on Wednesday, 14 September 2022 was $4.2827 and determined that the applicable AUD/USD exchange rate realised by ASXCL was 0.677838.

Standard Method of Adjustment

For an old contract size of 100 shares, the new contract size will be adjusted, using TMC threshold truncation.

Theoretical New Contract Size = Old Contract Size + (total special dividend paid per Old Contract Size/FX)/(S – OD/FX – SD/FX)

Theoretical New Contract Size = 100 + ($0.03/0.677838*100)/($4.2827-$0.14/0.677838-$0.03/0.677838)

=101.0977 truncated to 100 where the difference of 1.0977 will be cash adjusted based on the below formula.

Strike Factor = Old Contract Size/Theoretical New Contract Size

Strike Factor = 100/101.0977

                                                       = 0.989142

Please note that this is a non-rights style adjustment.

Cash Equalisation Adjustment Payments for Contract Size Roundings

The cash adjustment is calculated by taking the difference between the contract value of the option before and after the adjustment.  Variants to the formula apply for rights style adjustments and when the adjustment occurs on the day of the option’s expiry.

Cash adjustment = (BOP * BUV) – (AOP * AUV)

Where

BUV =Before (adjustment) Unit Value = BP * BU rounded to nearest cent

AUV =After (adjustment) Unit Value = AP * AU rounded to nearest cent

BU = units per lot (multiplier) before the adjustment (old traded entity)

AU = units per lot (multiplier) after the adjustment (old traded entity)

BP = for rights style, =SP/Adjustment Factor, for non-rights style=SP.

AP = for rights style, =SP, for non-rights style=SP * Adjustment Factor.

SP = settlement price of the option if not the options expiry day, otherwise the intrinsic price (underlying price-strike price for calls, strike-underlying price for puts) if on expiry date.  Refer Notes 1 and 2 below

BOP =pre-adjusted open position Refer Notes 1 and 3 below

AOP =post-adjusted open position Refer Notes 1 and 3 below

Note:

1. Cash adjustments on expiry will apply to exercised positions only.

2. The intrinsic price used for exercised positions on expiry is based on the adjusted strike price for rights style adjustments and the pre-adjusted strike price for non-rights style adjustments.  Set negative intrinsic prices to zero i.e. if an out of the money is exercised, the intrinsic price and hence cash adjustment is zero.

3. Pre and post adjusted positions will be the same unless there is a position adjustment factor applied to the open position associated with the adjustment.  For rights style use the start of day position (i.e. exclude any UA trading activity), for non-rights style use the (end-of-day) position prior to the adjustment.

4. Cash adjustments will also apply to LEPO positions.

5. For short positions, the result of the cash adjustment formula should have its sign reversed (multiply by -1). For non-LEPO positions the truncation approach ensures that the seller (writer) is always debited and the buyer (taker) is credited.  Because the LEPO strike is usually returned to 1c after the adjustment, the holder of a short LEPO position may be credited and long position may be debited.
