CHSCP's preferred stock is redemable right down. This seems to mean that the board has locked in a new redemption date of July 18, 2023. This is actually good news. I can't see why the stock is being dumped. Under this resolution, the company will not be able to redeem its preferred stock in after July 18, 2023. That's almost 10 years from today, which should secure the value of the preferred stock.
From the Form 8-K filed with the SEC on 7/19/2013 -- The Board of Directors of CHS Inc. adopted a resolution, which became effective on July 18, 2013, amending the terms of the Company's existing 8% Cumulative Redeemable Preferred Stock to provide that the 8% Preferred Stock may not be redeemed at the option of the Company until July 18, 2023. Prior to the effectiveness of the Resolution, the 8% Preferred Stock had been subject to redemption at the option of the Company from and after February 1, 2008.
