For purposes of this chapter, the term, control, means:
A person is presumed to exercise controlling influence when the person holds the power to vote, directly or indirectly, at least ten percent of the outstanding voting shares or voting interests of a licensee or controlling person. A person presumed to exercise controlling influence as defined by this section may rebut the presumption of control if the person is a passive investor.
To determine the percentage of a licensee or controlling person controlled by any other person, the person's interest must be aggregated with the interest of the person's spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law, and any other person who shares the person's home.
