Two Maryland casinos will keep a higher share of slot machine revenue when MGM National Harbor opens this week.
State lawmakers approved the added shares several years ago to help the two casinos make up for lost business after MGM opens.
Maryland Live! in Anne Arundel County will increase its share from 41 percent to 49 percent. Horseshoe Baltimore's share will rise from 39 percent to 46 percent. Those two casinos are the closest ones to MGM, which is in Prince George's County.
In another change, 5 percent of table game revenues will now go toward local impact grants, which mitigate the impact of casinos on surrounding communities. That cuts the share that goes to education to 15 percent. Casinos will still keep 80 percent of those revenues.
