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.

The Circle K operator cited Seven & i’s “lack of constructive engagement” in its decision to withdraw the bid, while Seven & i said it was disappointed but not surprised.

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.
