Canada's Alimentation Couche-Tard on Monday said it was resuming its share repurchase program days after the Circle K-parent scrapped its $46-billion attempt to buy Japan's Seven & I. The company said it would repurchase up to 77.

Couche-Tard, the operator of Circle K stores, after it said the 7-Eleven owner, Seven & i Holdings, refused to engage constructively on the deal.

Alimentation Couche-Tard Inc.’s decision to walk away in frustration from an attempted acquisition of Seven & i Holdings Co. set off a debate in Tokyo as to what lessons foreign companies with ambitions for M&A should draw.
