The expected bankruptcy of troubled air-bag maker Takata Corp. isn’t just a crisis for its employees and suppliers. It also throws a wild card into one of the biggest and most complicated recalls in automotive history.

The Japan-based auto supplier has pledged to recall and replace tens of millions of defective air-bag inflators used by 19 car and truck makers around the world, from Tesla Inc. to Toyota Motor Corp. Takata on Monday is expected to file for bankruptcy protection and announce a takeover offer from Key Safety Systems Inc. for about ¥180 billion ($1.62 billion), according to people familiar with the matter, who asked not to be identified because the information is private.

A filing to restructure doesn’t relieve a manufacturer of recall responsibilities. However, should its financial assets be exhausted before all the work is done, carmakers may have to cover the difference.

U.S. bankruptcy laws permit a would-be buyer to acquire Takata’s desirable assets, but not necessarily assume unwanted liabilities — including recall obligations, according to Robert Rasmussen, a University of Southern California law professor specializing in corporate reorganizations.

Funds raised by an asset sale will go toward funding Takata’s production of replacement parts, Rasmussen said. U.S. law treats a manufacturer’s recall obligations in bankruptcy as a claim of the U.S. government and they receive priority “to ensure that consumers are adequately protected from any safety defect” in a manufacturer’s products, according to the statute.

“The big risk,” Rasmussen said, “is how much are the assets worth versus what’s the cost to do the replacements.”

Scott Upham, president of Valient Market Research, estimates that automakers and suppliers globally face $5 billion in future costs tied to the recalls, about $2 billion of which can be tied to Takata. He estimates a Takata asset sale will generate about $1.5 billion to $2 billion.

“There’s not enough money,” Upham said. Automakers may have to cover any shortfall, he added.

The car companies have already shifted business away from Takata and toward rivals for about 70 percent of the parts to repair the millions of vehicles recalled for the company’s defective air bag inflators, which can explode with too much force and spray drivers and passengers with metal and plastic shards. That should assure enough new inflators for the estimated 100 million defective ones forecast to be replaced worldwide.

Only 38 percent of the 43 million air bag inflators under recall in the U.S. had been repaired as of May 26, according to data on the U.S. Department of Transportation’s National Highway Traffic Safety Administration website. In Japan, 73 percent of the close to 19 million air bags under recall have been repaired, a spokesman at the transport ministry said this month.

At least 17 deaths have been linked to the devices worldwide. Mounting liabilities associated with the faulty air bags have forced Takata to seek a buyer that would see it through a costly restructuring process. A Takata steering committee has recommended Key Safety Systems — the U.S. air bag maker owned by China’s Ningbo Joyson Electronic Corp. — as the preferred bidder, and bankruptcy filings will bring the Japanese company a step closer to a sale.

The challenges for the buyer are manifold.

Takata posted its third consecutive annual loss even without including the full costs of repairing millions of air bags, which automakers are now paying for. It faces a talent exodus and auto industry distrust. Takata didn’t respond to an emailed request for comment on its expected bankruptcy filing, while Key Safety Systems declined to comment on its bid for the company.

“It would be hard for Key Safety Systems to put in huge amounts of money if there’s no guarantee against unexpected liabilities, after any deal,” said Mitsuhiro Harada, a researcher at Tokyo Shoko Research. “Takata is making money in non-air bag operations, so if they can drastically cut recall-related debt through bankruptcy, they can surely revive soon.”

Automakers have avoided supply disruptions by sourcing replacement parts from Takata competitors Autoliv Inc., ZF-TRW and Daicel Corp. Autoliv, for example, has already provided 15 million replacement inflators and has orders for another 15 million into 2019, company spokesman Thomas Jonsson said.

“We are working with suppliers to ensure a steady supply of replacement inflators for our customers,” said Kelly Stefanich, a Toyota spokeswoman in Princeton, Indiana. “We don’t anticipate any supply disruptions at this time.” Honda Chief Executive Officer Takahiro Hachigo said at a June 16 media briefing that the automaker hasn’t heard any specifics about the Takata bankruptcy plan.

The government has said it is focused on completing the recall process and ensuring there is no disruption of the supply chain.

In the U.S., NHTSA has been coordinating the pace of recalls and the flow of parts under a legally binding 2015 agreement with Takata and 19 companies. That pact, NHTSA said, “is designed to deal with future contingencies, including the possibility of additional recalls, new information about the cause of the ruptures, or interruptions in the supply of replacement inflators.”

“The automakers, the government, Key Safety Systems and Takata will come to an agreement to keep supplies flowing,” Upham said. “The No. 1 priority is the safety of the driving public, and I think everybody realizes that.”

Honda first started recalling Accord and Civic models in 2008 due to the flaw that may end up being Takata’s undoing. The supplier’s inflators use ammonium nitrate propellant that can be rendered unstable after long-term exposure to heat and humidity. That same year, Takata began adding a drying agent to its propellant formula in an attempt to fix the problem. It has until the end of 2019 to prove to U.S. regulators that those air bags are safe.

Honda now uses no Takata-sourced inflators for recall repairs in the U.S., and none of the company’s new vehicles in mass production worldwide use Takata inflators with ammonium nitrate propellant, said Chris Martin, a Honda spokesman in the U.S.

Opting for bankruptcy protection in Japan and the U.S., as opposed to a court-led restructuring, should ensure there’s “minimum negative impact to the air bag supply chain for automakers,” said Takeshi Miyao, an analyst at Tokyo-based market researcher Carnorama. He predicts the procedure will take two months in a best-case scenario, but will more likely need about six.
