Date published: 09/10/17
Effective as of: 11/10/17
Last updated: 09/10/17

This Notice is being issued to provide Participants with further information on the Adjustment implication for WOR ETOs.

ASX Participants and ASX Clear (ASXCL) Participants are advised that WorleyParsons Limited (ASX Code: WOR) has announced an accelerated Non-Renounceable entitlement offer on 09 October 2017. The terms of the issue are 1 for 10 at $13.00 per ordinary share. The new shares will rank equally with existing shares on issue.  Participants are advised to refer to all announcements by WOR for details and the full timetables for the institutional and retail offer tranches. 

Implied Market Value of Accelerated Non-Renounceable Entitlement Offer

Participants are advised that the ETO adjustment will be based on the market value of the rights (whether positive or negative) as determined by ASX with reference to the VWAP for ex-entitlement shares and the entitlement price to subscribe for the new shares, and any dividend difference between the new shares and existing shares. 

The indicative timetable (from the ETO’s perspective) is:

WOR announcement of offer during commencement of trading halt

ETOs exercise restriction effective from

09 October 2017, pending adjustment

Monday, 09 October 2017

WOR shares resume trading, ex-entitlement basis

Wednesday, 11 October 2017

ETOs resume trading on an under adjustment “UA” basis (* see notes below)

ETOs exercise restriction lifted effective from 11 October 2017

Wednesday, 11 October 2017

ETOs trading on an Ex basis in line with the underlying

Wednesday, 11 October 2017


  • Participants may wish to consider making their clients, especially retail traders, aware of the issues relating to rights-style ETO adjustment for entitlement issues in relation to trading or exercise of ETOs on the ex-entitlement day. 

  • As with any rights-style adjustment that relies on market valuation, Participants are strongly advised that the adjustment to ETOs becomes effective on the commencement of ex-entitlement trading of the underlying securities. However, while any ETO trades entered into after the resumption of trading will be on an adjusted basis (“UA” Under Adjustment flag), the full extent of the adjustments will only be confirmed after VWAP and published by ASX after trading close on that day. Traders can estimate indicative adjustments when the market opens or during the course of the day.

Adjustment to ASX ETOs

ASX has consulted with ASXCL on the implications for WOR ETOs in relation to the entitlement offer. ASX will determine the following adjustment under ASX Operating Rule [2230] Adjustments, Appendix 2230 Procedure 10 Alternative Adjustments as follows:

New contract size is calculated as follows:

NC = OC + n*r/S 


NC       = new contract size

OC       = old contract size (currently 100)

n          = the number of entitlements or rights attributed to each OC determined by the issue ratio (1/10 *100)

r           = the market value (whether positive or negative value) of the each entitlement or right as determined by ASX, calculated as: S - d - C where: 

S  VWAP ex-entitlement of existing shares on the first day of trading ex-entitlement that the ETOs have also resumed trading (Wednesday, 11 October 2017), using the volume-weighted average price on ASX market.

d = ordinary dividend and special dividend for which the new shares are not entitled to (d=$0)

C = consideration paid to exercise the implied rights (i.e. offer entitlement price) (C=$13.00)

Participants should be aware that there are certain market conditions that can lead to a negative value for ‘r’.  A negative ‘r’ used in the calculation above will create an adjustment where the contract size is adjusted downwards and the exercise price is adjusted upwards.  Please see the recent example of Arrium Limited “ARI”.

The new strikes are calculated as follows:

New Strike = Old Strike * OC/NC


For the strike calculations, the new contract size used by ASX is rounded to 4 decimal places, and the strike factor (OC/NC) is rounded to 6 decimal places.

The strike factor (Old Contract Size/ New Contract Size) for all contract sizes will be based on the result calculated for the standard 100 contract size.

ETO Cash Equalisation Adjustment Payments for Contract Size Roundings

Participants should refer to Derivatives Notices 050/13 dated 14 August 2013, 042/13 dated 15 July 2013 and update 045/13 dated 17 July 2013 “ETO Cash Equalisation Adjustments for Contract Size Roundings” This is applied for all adjustment events effective 26 August 2013.

The cash adjustment payments will be posted by ASXCL as close as practicable to the effective adjustment date. For clarity, ETOs are LEPOs and non-LEPOs (ordinary options, American or European). Takers will be credited and writers debited a cash equalization payment for any contract size rounding calculations. (For share consolidations, it is possible for a LEPO taker to be debited if the LEPO strike is standardized back to 1 cent after initial rounding).

Where the old contract size of a series before an adjustment is 100, ASX will apply a standardizing “TMC threshold” so that if the calculated new contract size falls between 100 and to up to but not including 102, the new contract size will be truncated to the standard 100, and a cash equalisation adjustment payment made. 

OTC series (where any)

Clearing Participants are advised that any OTC series cleared by ASXCL under the ASX Equity OTC Clear service will be adjusted using the same formula as the ETOs as shown in this Derivatives Notice.

OTC series will be adjusted along with ETO adjustments on the night however, to maintain anonymity; the adjusted OTC series details will not be published in the Derivatives Notice but will be available to CPs the following morning via their own clearing systems.

ETO exercise restrictions (where any) in relation to an adjustment may occur during the period of 10 business days prior to and including expiry, will also apply to OTC series. However such exercise restrictions will not apply on expiry day of an OTC. 

Specific Cover

Participants are advised that as the contract size is changing, arrangements may need to be made for additional lodgement of underlying shares to account for any collateral denoted as specific cover. 

What do I need to do by when?

Participants should be aware of the content of this Notice as it sets out the treatment of the accelerated Non-Renounceable entitlement offer with respect to open positions in ASX WOR ETO contracts.

Exercises Restricted Pending ETO Adjustment

An exercise restriction was applied immediately to WOR ETOs after the announcement of the entitlement offer and the restriction will be lifted effective on the day trading resumes on an ex-entitlement (or ex-rights) basis

Effective Date

A further notice will be issued after the close of business following the resumption of trading of the underlying securities on an ex-entitlement basis, Wednesday, 11 October 2017. The notice will detail the adjusted contract size and adjusted strikes. Participants are reminded that trading on the ex-entitlement day will be on an “under adjustment” basis (UA trading) and effective that day, notwithstanding the adjusted specifications are published by ASX only after close of trading.
