The acquisition was effective as of the first day of the 3rd quarter, so no financials have been released showing the effects of the acquisition yet. They will be released November 16th, and yes, they are on a fiscal year.
I don't think the FSA bonds were de-listed in order for them to lose value because they were de-listed after the acquisition date, and the mark to market adjustment would have been made on the date of acquisition. Heck, I don't even know if their market value would have been part of the adjustment anyway.
I have no idea why they were de-listed. I'm a little ignorant when it comes to corporate bonds and how they work. Anyone else have an explanation?
