If you have read the dispute and researched similar cases, you will see that Lehman has a potentially legitimate claim against JBK. Hypothetically, if Lehman won this case and the JBK had to pay to cancel the swap as of September 2008, JBK is going to drop at least $5 in price from here. This security is not without risk. It's also not AAA.
There is literally zero chance that all holders will approve these expenses, which is why it looks like U.S. Bank wants a judge to overrride that. It may well be in JBK holders interest to pay those fees as the Lehman case against it has some complexity and it who is going to arbitrate this if no one pays the legal fees for JBK?
I owned a lot of JBK years ago, but have no position now and I'm going to wait on the sideline until this issue gets resolved, which could take quite a long time.
