Dividends are paid as a % of profit.
e.g. If profit is $5000 and the payout ratio is 60% then the dividend payout will be $3000 split between the shares.
If there are 100,000 shares then each share will have a dividend of 3c.
If there are only 10,000 shares then the dividend will be 30c a share.
So, I wouldn't worry about that.
What I would worry about is holding shares in a bank in a country in which the banking system has collapsed and where the country is almost certainly going to default.
