Condé Nast Publications will make deep staff cuts at two magazines, Portfolio and Men’s Vogue, and publish them less often while cutting budgets across the company by 5 percent, company executives said Thursday.

Men’s Vogue will all but disappear as a separate operation. It will be folded into Vogue and will be published twice a year instead of 10 times, the company said. Employees said they were told Thursday that most of the magazine’s staff would be laid off.

The business magazine Portfolio will be published 10 times a year instead of 12. Employees said they were told Thursday that most of Portfolio’s Web site staff would be dismissed and that much of the content unique to the site would be dropped.

Image Portfolio will be published 10 times a year instead of 12.

The company’s official position was that it had not yet determined where it would cut Portfolio, or how deeply, but executives who spoke on the condition of anonymity because they were not authorized to go into detail said they expected that 15 to 20 percent of the magazine’s jobs would be eliminated. Some of the cuts will involve Portfolio’s online operations, including advertising sales, which will be folded into those of Wired magazine.
