increase dividend: pay more to shareholders (as opposed to anything else the business could do e.g. CapEx or raises for labor)

do stock repurchases: basically a way to launder money by evading taxes. the long and short is that instead of paying shareholders $100 via dividends, which are taxable dividend income, the co spends $100 to buy the shares (say 50 shares at $2 each). if the shares were purchased for $1 each, then the basis increases by $1, so the it only creates $50 taxable income.

edit: mistake
