The Trust is managed to invest in a broadly diversified portfolio of eligible intermediate term domestic and global fixed interest and moneymarket securities. Within portfolio constraints, including controls on portfolio maturity, security maturity, credit quality and diversification,and adjusted to take into account certain Sustainability Considerations, the objective of the Trust is to maximise the return of the portfolio.

Dimensional takes into account certain labour standards or environmental, social, ethical or governance considerations ('Sustainability Considerations') when selecting, retaining or realising investments of the Sustainability Trusts. Specifically, Dimensional applies an assessment of a number of non-financial Sustainability Considerations it believes may be important to investors when making investment decisions for each of the Sustainability Trusts.

Sustainability Considerations taken into account for the Sustainability Trusts are based on available data, either actual or estimated, and our interpretation of the data. Definitions of the metrics 'revenue', ‘carbon intensity' and ‘potential emissions from reserves' used as part of applying the Sustainability Considerations are outlined in theAdditional Information Guide under the heading ‘Data definitions’ on page 12.

Each of the Sustainability Trusts has a carbon footprint reduction goal. Specifically, the Sustainability Trusts aim to have a reduction in weighted average carbon intensity, and reduction in weighted average potential emissions from reserves, relative to a particular benchmark index (‘Carbon Footprint Reduction Goal’) as detailed in the table below. For any Sustainability Trust that invests in other funds managed by Dimensional, such as the Dimensional Sustainability World Allocation 70/30 Trust and the Dimensional Sustainability World Equity Trust, the Carbon Footprint Reduction Goal is for each of the underlying Sustainability Trusts it is invested in to meet their respective Carbon Footprint Reduction Goals. There is no guarantee that a Sustainability Trust will meet its Carbon Footprint Reduction Goal. For more information, please refer to the Carbon Footprint Reduction Goals for the Sustainability Trusts in the Additional Information Guide on page 9.

Dimensional intends to achieve the Carbon Footprint Reduction Goal for each Sustainability Trust by ranking companies at a portfolio and sector level on metrics described below. Specifically, these metrics relate to carbon emissions and are applied to increase exposure (i.e. overweighting) to companies with lower emission profiles and decrease exposure (i.e. by underweighting or excluding) to companies with higher emission profiles.

For the Sustainability Trusts that are Fixed Interest Trusts:

Portfolio level

From a portfolio level, securities with higher emission profiles are treated in the following manner:

·          Generally, based on Sustainability Score, corporate bonds of companies ranking in the worst 10% of a Sustainability Trust’s eligible universe by market value will be excluded;

·          Generally, securities of corporate, agency and supranational issuers with relatively high potential emissions from reserves will be excluded; and

·          Generally, securities of agency and supranational issuers whose carbon intensity is higher than the worst 10% of the corporate universe by market value will be excluded.

Sector level

Corporate issuers in each sector are ranked by carbon intensity and categorized as a low, medium or high carbon intensity issuer. The Sustainability Trusts that are Fixed Interest Trusts will generally overweight the group of issuers with lower carbon intensity, and underweight the group of issuers with higher carbon intensity.

For the Sustainability Trusts that are Equity Trusts and Fixed Interest Trusts, in relation to the Carbon Footprint Reduction Goal, the above processes mean that individual securities are evaluated relative to the broad universe of securities and against sector peers rather than against strict individual sustainability targets, such as absolute maximum emissions criteria or minimum scoring criteria. Also, because the Carbon Footprint Reduction Goal is applied at the portfolio level, the Sustainability Trusts may overweight a security which has a worse Sustainability Score compared to sector peers or other eligible securities where doing so still achieves the Carbon Footprint Reduction Goal.

Inaddition to the Carbon Footprint Reduction Goal, as part of the screeningprocess the Sustainability Trusts generally exclude companies which meetcertain involvement criteria (which include revenue thresholds) in thefollowing business practices: coal, factory farming, palm oil, controversialweapons, nuclear weapons components, systems and support services, tobacco,child labour, alcohol, gambling, adult entertainment, and personal firearms.
