What this fund is
Objective, as filed

The investment objective of the Portfolio is to realize as high a level of total return as is consistent with reasonable investment risk through appreciation and income.

Strategy, summarised

The fund operates as a fund of funds, investing in a combination of actively managed and passive underlying portfolios and exchange-traded funds to allocate assets across equities, fixed income, and cash equivalents according to a balanced target allocation. The adviser adjusts allocations among underlying funds in response to changing market conditions and may concentrate more than 25% of assets in a single underlying fund or ETF. Because underlying portfolios or ETFs may themselves be non-diversified or invest heavily in single issuers, sectors, or geographic regions, the fund's returns depend on the adviser's selection and weighting of those underlying vehicles.

The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.
