Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.</font></div><div><font><br></font></div><div><font style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%;">Report on Supplemental Schedule</font></div><div><font><br></font></div><div><font style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">The supplemental schedule listed in the table of contents has been subjected to audit procedures performed in conjunction with the audit of the Plan&#8217;s financial statements.

In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in compliance with the Department of Labor&#8217;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.

The beneficial interest of each participant is represented by units.  Units are issued and redeemed daily at the Fund&#8217;s NAV determined as of the close of business each day.  Distribution to the Fund&#8217;s unit holders is declared daily from the net investment income and automatically reinvested in the Fund on a monthly basis, when paid.
