To assist you with the answer, as someone working for a FTSE100 company with a mandatory ethics code applicable to all employees, imagine I am Chiara.
The disagreement on accounting principles between me and my supervisor is that I believe 50% of the company’s profits are to be paid directly into my personal bank account.
Under option 1; on resignation that it the end of the matter, and I can keep the 50% of the company profits.
Under option 2; on resignation they might have a right to sue me for the money I stole and report that theft to the police.
Under option 3; on resignation, after reporting the matter to AICPA (whoever they are), that is the end of the matter, and I can keep the 50% of the company profits.
Option 4; none of the above.
