Many companies are facing challenges to hire and retain qualified accounting personnel in the United States. As a result, these companies are facing issues with accurate and timely financial reporting to the parent companies in Japan. It has been a challenge for many companies to establish adequate corporate governance and management systems to effectively oversee the subsidiaries outside of Japan.

Post Merger Integration (PMI) Support

Post merger integration (PMI) is a very challenging process for many companies. The accounting department will be under increased pressure because of the tight closing and reporting schedules for the first quarterly and year-end reporting immediately after the acquisition. It is often difficult to gather all necessary information for timely reporting due to different cultures or lack of resources. We have also seen many occasions that adequate internal controls were not in place at the acquired companies.
Our professionals with extensive experience will support your PMI process including establishment of necessary accounting policies, accelerated book closing and establishing adequate internal controls.
