Indemnification

5 - Indemnification

Under the Trust's organizational documents, the Sponsor is indemnified against liabilities or expenses it incurs without negligence, bad faith or willful misconduct on its part. 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.
