    <fnd:NmRule35d1TermDfnTextBlock contextRef="AsOf2026-09-09" id="Fact000012">Under normal circumstances, the trust
will invest at least 80% of the value of its assets in dividend-paying securities. The trust consists of a diversified portfolio of dividend-paying
equity securities. The sponsor believes that dividends are often a good indicator of a corporation&#x2019;s current financial condition
and, furthermore, may signal management&#x2019;s belief in a profitable future for the corporation. Investors seeking to return to the
often volatile equity markets may consider the income available from a group of dividend-paying securities as a logical first step toward
reentry into such markets. However, there can be no assurance that any security held by the trust will meet the trust&#x2019;s objective.</fnd:NmRule35d1TermDfnTextBlock>
