Pinterest’s initial public offering has generated $2 million in legal fees for the three firms guiding the deal—New York-based white-shoe law firm Cleary Gottlieb Steen & Hamilton; underwriter counsel Skadden, Arps, Slate, Meagher & Flom; and Delaware midsize firm Potter Anderson & Corroon.

The social media company, whose stock is expected to begin trading next week, disclosed the legal fees and expenses in an updated prospectus filed with the U.S. Securities and Exchange Commission Monday.
