The document compares and contrasts share sales versus asset sales when structuring the sale of a business. A share sale involves the change of ownership of a company but not the business identity, while an asset sale changes the business identity. Key factors to consider for each include tax liabilities, employees, contracts, documentation needs, and the transfer of disputes. Overall, share sales are typically more expensive and complex but allow for cleaner transfer of contracts and tax liabilities, while asset sales are usually cheaper and simpler but require renegotiating contracts and result in tax on asset disposals. The document advises agreeing on the sale structure upfront.
