Layoffs are coming to Carat's U.S. operations, according to an email that was accidently sent to employees of the media agency.

Ad Age broke the news of the email and the coming layoffs, which had been circulated throughout the company.

The extent of the layoffs remains unclear. However, Carat, which called the layoffs part of a "right-sizing" effort, indicated that the cuts would impact offices in Boston, Chicago, Dallas, Los Angeles and San Francisco.
