Segment Reporting The Chief Executive Officer and Chief Financial Officer of the Sponsor act as the Trust’s chief operating decision maker (“CODM”). The Trust represents a single operating segment, as the CODM monitors the operating results of the Trust as a whole and the Trust’s passive investment objective is pre-determined in accordance with the terms of the Trust Agreement. The financial information in the form of the Trust’s total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations and capital share transactions), which are used by the CODM to assess the segment’s performance, are consistent with that presented within the Trust’s financial statements. Segment assets are reflected on the accompanying Statements of Assets and Liabilities as Total assets and the only significant segment expense, the Sponsor’s fee, related party, is included in the accompanying Statements of Operations. 3.
