2. Sarah, Lisa and Adriana are accountants and decide to form the limited liability partnership of SLA Accountants, LLP. They register the partnership with the state. Adriana then conducts an audit of the financial statements of DEF, Inc. and her audit team includes Anna, an audit manager who is under the supervision of Adriana during the course of the audit. Anna makes a major mistake in checking the assets of DEF with the result that the assets listed on the financial statements are overvalued and the liabilities are undervalued. DEF is a publicly traded stock and when the market finds out about this mistake, the value of the shares goes from $50/share to $5/share. The shareholders sue Sarah, Lisa and Adriana for negligence.
