Schedule FA - Foreign Stocks

Income Tax Income from Capital Gains
1

I have an account with a foreign broker which I use to buy US stocks.
Sources of income with this foreign broker account:

  • Interest income from broker
  • Dividend income from US stocks
  • Capital gains from US stocks

Not sure in Schedule FA whether I should fill A2 or A3.
Reasons why I think A2 is appropriate:

  • I have cash balance at the broker
  • I get interest income from the broker on that cash balance
    The above two points cannot be accommodated in A3

But I also cant skip A3, because I am the BO of the US stocks, so need to provide details of the US stocks in A3.

Wont filling both A2 and A3 result in double reporting, because A2 already includes all the details for A3?
