For PFG, they filed a 10Q on 22 April 2015 and noted they had 294,385,885 shares outstanding of their common stock.  They also noted for the three months ended March 31 2014 that dividends were paid to both common stockholders and preferred stockholders and that there were Series A preferred stock (3 million) and Series B preferred stock (10 million), plus a statement: In February 2015, our Board of Directors authorized a share repurchase program of up to $150.0 million of our outstanding common stock. Shares repurchased under these programs are accounted for as treasury stock, carried at cost and reflected as a reduction to stockholders’ equity. Therefore the exact amount of dividend paid out will not be known until the next quarterly report which will state the exact amount of dividend paid out to common and preferred shareholders for the quarter.
