Holders of our Preferred Stock are entitled to receive, when and as declared by the Board out of funds of the Company available for the payment of distributions, quarterly cumulative preferential cash dividends of $0.5625 per share of the $25.00 per share stated liquidation preference on our Preferred Stock. Dividends on the Preferred Stock are payable quarterly in arrears, on April 30, July 31, October 31, and January 31, of each year. During the three months ended October 31, 2023, the Board declared a quarterly dividend on our Preferred Stock. The Company has approximately $4.7 million of cumulative undeclared preferred dividends as of October 31, 2023. On September 28, 2023, the Board approved the Reverse Stock Split at a ratio of one-for-ten. On October 12, 2023, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to its Charter Amendment to effect the Reverse Stock Split. The Charter Amendment became effective on October 13, 2023. As a result of the Charter Amendment and Reverse Stock Split, every ten shares of issued and outstanding Common Stock were combined into one issued and outstanding share of Common Stock, without any change in par value per share. Proportionate adjustments were also made to any outstanding securities or rights convertible into, or exchangeable or exercisable for, shares of Common Stock. Fractional shares were not issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to receive a fractional share were entitled to receive one full share of post-Reverse Stock Split Common Stock, in lieu of receiving such fractional shares.

The Reverse Stock Split reduced the number of shares of issued and outstanding Common Stock from approximately 13,788,738 shares to approximately 1,405,779 shares. Common stock and treasury stock shares have been retroactively adjusted to reflect the Reverse Stock Split in all periods presented. In connection with the reverse stock split, the Company retired all treasury stock.
