On March 2, 2015, Best Buy Co. announced that it planned to repurchase up to $1 billion of its common shares. The company also announced on that day that an increase in its quarterly dividend from $0.19 to $0.23 per share, and a one-time special dividend of $0.51 per share. The special dividend resulted from a windfall legal settlement related to the manufacture of liquid crystal displays it had sold.

Which method of returning capital to investors (repurchases, regular dividends, special dividends) do you think is viewed by shareholders most favorably, and why?
