请问老师，structure model 是否能解释什么时候违约？ 像reduced-form model一样

Example 1 (Notification of Known Violations): Michael Allen works for a brokerage firm and is responsible for an underwriting of securities. A company official gives Allen information indicating that the financial statements Allen filed with the regulator overstate the issuer’s earnings. Allen seeks the advice of the brokerage firm’s general counsel, who states that it would be difficult for the regulator to prove that Allen has been involved in any wrongdoing. Comment: Although it is recommended that members and candidates seek the advice of legal counsel, the reliance on such advice does not absolve a member or candidate from the requirement to comply with the law or regulation. Allen should report this situation to his supervisor, seek an independent legal opinion, and determine whether the regulator should be notified of the error. 没明白这个案例到底谁 错在哪里？
