The dividend payout already occurred over a month ago in terms of stock going ex dividend. Actual dividend is being paid on 7/31, but those buying AI now do not get that div payment, as it is ex div since almost a month.
I think, AI is earning at present, around $1.10 per quarter and pays out 87.5 cents per quarter , so the div payment is covered by earning for now. Mgmt has indicated in last conf call, that outlook is stable.
I think, dividend of 15% is stable for 2012 and 2013 years.
