United Financial shareholders voted in favor of the merger on Oct. 22. United Financial’s common stockholders will receive 0.875 shares of People’s United common stock for each share of United Financial common stock.

Hartford-based United Bank, which has branches in Connecticut and Massachusetts, had $7.3 billion in assets as of June 30, making it Connecticut’s third largest bank.
