The Modern Portfolio Theory
In my blog yesterday, I introduced the prudent investor rule as the standard of care for trustees when investing assets that are held in a trust. Today, I will address how a trustee’s investment performance may be assessed.
Prior to July 1999, trustees were required to make investments pursuant to the “statutory legal list” provided for in the Trustee Act. This had the effect of holding trustees accountable for each particular investment, rather then the investment portfolio as a whole. The principle was further illuminated by the anti-netting rule, which stated that a trustee, who committed a breach of trust, was not entitled to set off a gain in one transaction against a loss in another. However, through recent amendments to the Trustee Act, the statutory legal list was repealed and replaced with the Prudent Investor Rule.
The Prudent Investor Rule reflects the modern portfolio approach to investments, the emphasis being on the prudence of the portfolio as a whole as opposed to each particular component. This theory is captured in Section 27(5) of the Trustee Act. Section 27(5) requires “a trustee to consider … the role that each investment plays within the overall trust portfolio”. Furthermore, under section 27(6) “a trustee is required to diversify the investments of the trust property. It appears that under the modern portfolio approach, a trustee would not be breaching the standard of care, should he or she invest a substantial amount of trust assets into a single security. As described above, section 27(6) requires that the trustee consider diversifying the portfolio, which is necessary if the Prudent Investor Rule is to be followed. To conclude my topic, tomorrow I will consider the liability of a trustee with respect to the investment of trust assets.
