Takata Corp., the supplier behind the auto industry's biggest recall ever, estimated that a comprehensive callback of its air bag inflators would total about ¥2.7 trillion ($24 billion), according to a person familiar with the matter.
The worst-case recall scenario would involve 287.5 million air bag inflators, said the person, who asked not to be identified because the company's deliberations are private. Takata and the automakers still have to determine how the costs are shared, the person said. A representative for Tokyo-based Takata declined to comment.
Takata shares plunged by 20 percent to close at ¥414 on Wednesday, hitting the lower daily limit in Tokyo trading. The shares have declined 49 percent this year, compared with the 12 percent decline for the benchmark Topix index.
