Boeing Co (BA.N) Chairman Jim McNerney on Wednesday said the aircraft maker is actively looking at moving “key pieces” of its operations to other countries given uncertainty about the future of the Export-Import Bank, whose charter expired on June 30. McNerney, who retired as the company’s chief executive on July 1, said Boeing might consider sites in countries that offer export credits, but gave no details about which operations could be affected or when the company had launched its review.
