The New York Times Co. announced today the appointment of Walter Mattson as president of the company.

The company's five operating divisions -- which include the Times newspaper, other newspapers, magazines, book publishing and broadcasting -- will report to Mattson who previously served as executive vice president and general manager at the New York Times newspaper.

Arthur Ochs Sulzberger, chairman and president of the company, will give up the presidency but remain as chairman and chief executive officer, the company announced.

The Times also announced several other executive changes and reported that its second-quarter earnings totaled $9.4 million (80 cents per share) on revenues of $1.66 million, up from profits of $8.2 million (70 cents) on sales of $147 million a year ago.

The company also said it would boost its annual dividend to 90 cents per share (22.5 cents a quarter) from 80 cents.

Among the other executive changes:

Sidney Gruson, formerly executive vice president in charge of affiliated companies, was named vice chairman of the board and deputy to Sulzberger. Gruson will also head an expanded corporate development group.

James Goodale, formerly executive vice president, will also become a vice chairman of the board and the company's general counsel.

Mattson, Gruson and Goodale were also named to the Times board of directors, which will be expanded to accommodate them.

John D. Pomfret, assistant general manager of the Times newspaper, has been named general manager of the paper to replace Mattson.
