What is the duty of a trustee to keep the beneficiaries of a trust reasonably informed of the trust and its administration?

The Pacific parties cite section 16060 for the proposition that the trustee has a duty to keep the beneficiaries of the trust reasonably informed of the trust and its administration. The information provided pursuant to section 16060 must be the information reasonably necessary to enable the beneficiary to enforce the beneficiary's rights under the trust or prevent or redress a breach of trust.
