Compensation information is available in the annual reports (10-k filings) which are available from the SEC EDGAR system or, generally, the company's website. Additionally, insider transactions are reported to the SEC so you can see when an insider buys or sells stock or exercises options received as compensation.
Background: Nowadays board and officers seem to secretly steal money from shareholders through options and other ways. The stock buybacks that people think should boost the earnings per stock is in reality issued back to the management of the company and is a more stealth way to take money from the company compared to take higher salaries.
... How do you know this is happening if you don't know where to go to get the data needed to determine whether or not this is happening? Do you really think company share buybacks involve just the amount of shares to pay an executive? Apple has bought back $117,000,000,000 worth of shares from the fourth quarter 2012 through the second quarter 2016, and paid a pretty substantial amount in dividends over the same period. Do you really think these shares were simply handed to the executives? The huge pension funds and other huge investors would not let this slide for very long if it were even close to being true.
Don't come to an unfounded conclusion then seek data to prove your position. Look at and analyze data THEN come to a conclusion.
