Northwest Airlines Corp. hasn't disappeared in bankruptcy, but its shares are about to get harder to find.
Northwest, which filed for Chapter 11 bankruptcy protection on Sept. 14, said its shares will stop trading on the Nasdaq Stock Market on Monday. Its ticker symbol has already changed from NWAC to NWACQ. The shares are expected to continue to trade on the over-the-counter market.
Delta Air Lines Inc. also filed for bankruptcy protection on Sept. 14. The New York Stock Exchange said last week that it is continuing to review Delta's listing.
Bankruptcy filings don't automatically make a company's shares worthless, but the shares are usually canceled when the company reorganizes.
