Stock dividend, not a stock split each quarter. Your broker holds the fractional shares and adds them to the next dividend rather than selling the fractional. At least that's what Merrill Lynch does for me.
One more thing. If you purchase KMR through a broker, be sure you get part shares as such if you do not want any cash or tax consequences. I bought originally through Ameritrade and for quite a few years received shares plus part shares in cash. I wanted no cash so I eventually changed that account to Vanguard which distributed shares and part shares and no cash.
It is a quarterly dividend. Check the Interactive chart and click in "splits" under the tab "events" on top of the chart on a 1 year chart. It will quickly give you an approximation. They usually announce the dates 2 weeks or so in advance of ex-date and at that time the exact date can be established. Pay date follows by about 3-4 weeks after. You receive additional shares at that time. Check out company website.
