Commitments and Contingencies Disclosure [Abstract] |
Indemnification | 5. Indemnification Under the Trust’s organizational documents, the Trustee (and its directors, employees and agents) and the Sponsor (and its members, managers, directors, officers, employees and affiliates) are indemnified by the Trust against any liability, cost or expense it incurs without gross negligence, bad faith, willful misconduct or willful malfeasance on its part and without reckless disregard on its part of its obligations and duties under the Trust’s organizational documents. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred.
