Dividends depend on the possibility of the corporations to pay them.
there are conditions for corporations to pay dividends or decide not to do so (as in the real world).
it depends on the profit, and cash reserves of the country and of course, on the situation on the market for the product produced by the corporation.
so dividends are not stable, they change all the time.
Example:
if you have electric power companies, factory upgrades, household products and a bunch of others,
they probably will not pay dividends now, or less as there have been some surpluses of the products.
It will probably restore itself and dividends will return.
