Umm... I think its more like the 'Mandate' from their Investors requires them to invest in only 'Debt' instruments (AKA 'Income/Interest-bearing instruments) rather than any 'Growth/Equity-based Instruments'...And since already the 'remaining' portion of these 'Debt Securities' have been negotiated by LBHI to receive some sort of 'Equity' in future, they have no option but to sell off their remaining Claims to other parties that are not restricted in having 'Debt-to-Equity Exchange' agreements, as part of their Investment mandates....
