In my opinion, it is financial due diligence that is buyer’s main concern. Even after cursory review of financial statements and audit reports of the target company, the purchasing company should try and infiltrate into the company operations to ensure reports and reality are aligned. All too often, financial statements and audit reports portray a rosy view of a company that might not be aligned with reality. It is the buyer’s duty to look for anomalies in the financial statements and follow investigation through into operations (if possible). I don’t not believe this varies between companies, industries, and countries.
