Yellow pages publisher and online marketing services firm Dex Media (NASDAQ:DXM) is closing the books on 44 jobs at its Cary location.

The layoffs are not unexpected. After Cary-based Dex One announced a merger with Texas company SuperMedia last year, the companies said that the combined company now called Dex Media would operate its headquarters in Fort Worth, Texas.

Disclosure of the permanent layoffs came in a notice filed with the North Carolina Department of Commerce as required under the federal Worker Adjustment and Retraining Notification Act, or WARN. That law requires notification when a company closes plants or makes mass layoffs.

Last August, Dex One announced it would merge with rival SuperMedia to form a company with combined annual revenue topping $3.1 billion. At the time, both companies together employed approximately 5,800. But the company said that with the merger it expected to reduce its workforce by between 10 and 15 percent across the combined company.

The merger was completed on April 30. The Dex One WARN notice was filed with the state on July 19, according to the state filing. In a letter to the state, Dex Media said that the layoffs began in May and all affected employees were given 60 days notice. Positions affected by this round of layoffs include several executive posts including the President and CEO, the Senior Vice President Chief Strategy Officer, and the Senior Vice President General Counsel & Chief Administrative Officer.

Dex Media spokesman Chris Hardman said that the company now employs about 225 in the Triangle and 5,000 employees total. He added that “additional company layoffs are likely as we continue through merger integration.”

In the last last annual report filed as Dex One, the company reported that it employed approximately 2,300 employees as of March 31. At one time, Dex One employed 300 in Cary.
