Terms explained

Cost base, reduced cost base and acquisition date

Your CGT records for your ABB Grain shares should show your cost base and acquisition date (the date you got your shares) for each parcel of ABB Grain shares. Generally, the cost base of shares is the purchase price and any incidental costs, such as transfer fees and stamp duties, and fees charged by consultants, accountants, lawyers or brokers.

If you have to work out a capital loss, you use your reduced cost base rather than cost base. Your reduced cost base does not include indexation or certain other expenditure.

For most people, your reduced cost base is the same as your cost base.


If you acquired ABB Grain shares when the Australian Barley Board privatised on 1 July 1999 or when ABB Grain merged with AusBulk Ltd and United Grower Holdings Ltd on 27 September 2004 and need to know the acquisition date or cost of those shares, refer to the ABB Grain website or the Viterra website.

Discounted capital gain

If you work out your capital gain using the 'discount method', you reduce (or discount) the capital gain using the 'CGT discount'. The result is referred to as a 'discounted capital gain'. If you use the discount method to work out your capital gain, you do not index the cost base.

The discount percentage is the percentage by which you discount your capital gain after you have applied all the capital losses for the income year and any unapplied net capital losses from earlier years.

The discount percentage is 50% for individuals and trusts, and 33% for complying superannuation entities and eligible life insurance companies.

Parcel of shares

If you acquire more than one share on a particular date for a particular price, we refer to those shares as a parcel of shares. For example, you may have bought ABB Grain shares on two occasions on the Australian Securities Exchange (ASX). Each of these acquisitions is a separate parcel.

Although each share is a separate CGT asset, it is usually more convenient to work out the CGT consequences for each parcel of shares.


Using the worksheet will be easier if you enter your parcels of shares in the order you acquired them, starting with the oldest.

End of attention

Scrip-for-scrip rollover

Rollover allows you to defer your CGT obligation until a later CGT event happens to your shares or CDIs. If you received shares or CDIs plus cash for your ABB Grain shares, you are only eligible for partial rollover. If you received only cash you are not eligible for any rollover.
