Japanese auto parts giant Takata Corp., which followed its U.S. unit into a Delaware bankruptcy court this week, revealed in court documents that it is paying nearly $1 million per month to an Am Law 100 firm advising it in product liability litigation over faulty air bags.

A court filing Tuesday in Takata’s Chapter 15 case by Covington & Burling partner Shankar Duraiswamy in Washington, D.C., revealed that between January and June of this year, Takata has paid roughly $877,000 each month in legal fees and costs to his firm for work in air bag-related litigation. That would put the amount that Covington has earned this year from Takata’s Japanese parent at nearly $4.4 million.
