Preferred shares are equity, not debt.
When you bought Preferred A shares, you accepted this deal. Ideally, you read and understood the prospectus and decided the benefits outweighed the risks but in any case that is the deal that you accepted.
ideally, you read the latest financial statements, which somehow magically showed $250 million into a category called "short term liabilities". those are not earmarked for mtn payment, but rather preferred a repayment upon retraction. and if that isn't enough to convince you, the magic of time in 7 days might.
