So from what I can see, the company performed a debt-for-equity swap to avoid bankruptcy, and gave new shares to creditors to write off debt. But as a normal shareholder, is there any benefit to this other than hopefully the company doing well in the future? All I can see is that I lost 20% and surely this swap would’ve been known long in advance so I could’ve sold before and bought back in afterwards? Am I missing something?
