The Options reference the share price of the Market Reference (the &#x201c;&lt;/span&gt;&lt;span style="font-style: italic"&gt;&lt;i&gt;Market Reference Level&lt;/i&gt;&lt;/span&gt;&lt;span&gt;&#x201d;), which was $750.72 (the &#x201c;&lt;/span&gt;&lt;span style="font-style: italic"&gt;&lt;i&gt;Initial Market Reference Level&lt;/i&gt;&lt;/span&gt;&#x201d;) at the time the Options were executed. The Options entitle or obligate theholder to purchase or sell shares of the Market Reference at each Option&#x2019;s strike price on October 18, 2027 (the &#x201c;&lt;span style="font-style: italic"&gt;&lt;i&gt;Option Expiration Date&lt;/i&gt;&lt;/span&gt;&#x201d;). The Options are European style options, which means that they are exercisable at the strike price only on the Option Expiration Date. The Options are intended to be liquidated on or prior to the Option Expiration Date, rather than be exercised, in order to avoid having the trust receive shares of the Market Reference or be obligated to deliver shares of the Market Reference.The Options are intended to generate returns based on the price performance of the Market Reference. The trust&#x2019;s performance will not reflect the payment of dividends by the Market Reference. The Market Reference is an exchange-traded fund that seeks to track performance of the S&amp;amp;P 500&lt;sup style="font-size: 9pt; line-height: 9pt"&gt;&#xae;&lt;/sup&gt;&lt;span&gt; Index (the &#x201c;&lt;/span&gt;&lt;span style="font-style: italic"&gt;&lt;i&gt;Underlying Index&lt;/i&gt;&lt;/span&gt;&#x201d;). See details about the Market Reference and Underlying Index under &#x201c;Understanding Your Investment &#x2014; Additional Information about the Principal Investment Strategy &#x2014; The Market Reference and the Underlying Index&#x201d;.</fnd:NmRule35d1TermSlctnCritTextBlock>

                normal market conditions, the trust will invest at least 80% of its net assets in Options that provide exposure to large
