The accounting estimates that require management’s most difficult and subjective judgments include revenue recognition, income taxes, website development costs and internal-use software, purchase price allocations for business combinations, valuation of goodwill and intangible assets, leases, stock-based compensation and restructuring and other exit costs. The Company evaluates its estimates and judgments on an ongoing basis and revises them when necessary. Actual results may differ from the original or revised estimates.</font></div></div>
