You can find the answer by going to the MetLife Investor Relations page where you will see the dividend payout history, stock information, etc.. (investopedia.com)
For example if we look at the Microsoft investor relations page, we can see that they pay a dividend of $ 0.11 per quarter which totals to an annual amount of $ 0.44. (abcsofinvesting.net)
However, I have trouble finding such a page on a central BYD corporate investor relations page. (money.stackexchange.com)
