Step-by-step explanation:
Investment reviews do not necessarily need to be performed on all trust accounts annually. The need for investment reviews depends on various factors such as the size and complexity of the trust, the terms of the trust agreement, and the regulations governing trust accounts in a particular jurisdiction.
For larger and more complex trusts, it is common practice to conduct annual investment reviews to ensure that the investments are performing well and align with the trust's objectives and risk tolerance. However, for smaller and less complex trusts, investment reviews may be conducted less frequently, such as every three to five years.
Ultimately, the decision to perform investment reviews and the frequency of those reviews is determined by the trustee and should be guided by fiduciary responsibilities and best practices in trust management.
