The Trust provides investors with the opportunity to invest in high quality office properties. The Trust seeks to optimise returns to investors through ongoing active management of its property investments, the acquisition of further property investments as opportunities arise, and the sale of property investments where this is judged to be in the interests of its investors.

While the Trust will sell its property investments where appropriate, it is not intended that the Trust will be an active trader. Property investments are generally held with the intention of long term ownership. In considering future acquisitions, the key criteria will be the enhancement of risk adjusted returns to investors. Both initial and expected future returns are considered. Potential benefits to investors which are considered include the potential to increase distributions, additional diversification of the Trust's portfolio or other factors such as extension to lease expiry profiles, which may lower the Trust's investment risk.

The principal focus of the Trust's investment activities is office assets which meet the following investment criteria:
     
 
A single-tenant or multi-tenant stabilised office building located in a prime central business district or an associated suburban market;
 
Properties which are not expected to require significant development or redevelopment efforts but may require material capital improvements in connection with re-leasing as current leases expire; and
 
Properties which are expected to be substantially leased to tenants for at least the three year period following the acquisition.
     

In the future, the Trust will actively consider acquisition opportunities in markets outside the US.
