Six months after filing for bankruptcy, Toys R Us said today that it will close all its U.S. stores and 100 in the UK, writes the Washington Post's Abha Bhattarai.

Why it matters: The Amazon effect is one reason for the iconic chain's misery. But the other is the $6.6 billion in debt that Vornado, Bain Capital and KKR laid on Toys R Us after a leveraged buyout in 2005, some $5.2 billion of which remains.
