Context

• These are institutional transactions in auction-rate/preferred securities, not trades by a company executive. Institutional disposals of preferred-series securities often reflect balance-sheet or client-related activity rather than a direct view on the issuer’s equity prospects. Because this was a disposition (not a purchase), it is generally less indicative of a bullish signal from an insider.
