i am having a hard time with calculating a cumulative and non-cumulative preferred stock problem. i answered half of the problem correctly but i get the other half wrong. here is the question:
AI Corpation issued 100,000 shares of 20 par value, cumulative, 8% preferred stock on january 1, 2007, for $2,100,000. In December 2009, AI declared its first dividend of $500,000.
*Prepare AI's journal entry to record the issance of the preferred stock.
I did the journal entry and its correct.

Cash 2100000
preferred stock 2000000
paid-in cap. in excess of par value 100000

Here is the second part to the question:
If the preferred stock is not cumulative, how much of the $500,000 would be paid to common stock?


If the preferred stock is cumulative, how much of the $500,000 would be paid to common stock?



Now, i figure 2,000,000 if the pref. stock is cumulative but im uncertain of this figure.
could someone help me??
