On June 4, 2020, we completed our acquisition of Mathway, LLC (Mathway), an online, on-demand math problem solving company that provides a vast range of subject areas in mathematics, including pre-algebra, algebra, trigonometry, pre-calculus, calculus, and linear algebra, and related disciplines. This acquisition helps to strengthen our existing Chegg Math Solver service with the addition of new subjects, languages, and international reach. The total fair value of the purchase consideration was $101.0 million, of which $93.5 million was paid in cash on the acquisition date and $7.5 million, included within accrued liabilities, was held in escrow as security for general representations and warranties and potential post-closing adjustments. Any remaining escrow amount will be released 15 months after the acquisition date.

The Mathway purchase agreement provides for additional payments of up to $15.0 million subject to the achievement of specified milestones and continued employment of the sellers. These payments are not included in the fair value of the purchase consideration but rather are expensed ratably as acquisition-related compensation costs classified as research and development and general and administrative expenses, based on the seller's job function, on our consolidated statement of operations. We have recorded approximately $2.9 million as of December 31, 2020, included within accrued liabilities on our consolidated balance sheet for these payments.
