Shares of American Apparel Inc. jumped nearly 17 percent late Friday after the struggling manufacturer and retailer said that NYSE Amex regulators had agreed to its plan to avoid delisting.

The Los Angeles company said that regulators also granted the company an extension, until Nov. 15, to get current on its Securities and Exchange Commission filings. American Apparel was warned in August that its failure to file timely quarterly financial reports left it open to being delisted.

American Apparel has blamed the delay on a change in auditors, with the new accounting firm needing more time to file second quarter results and final results for the first quarter. Deloitte & Touche LLP resigned on July 22, stating that the company’s annual results from last year may not be reliable.

Shares closed up 21 cents, or 17 percent, to $1.46 after the late afternoon announcement, and were up 27 percent for the week.
