Marcum understands the importance of staying up-to-date with national and international accounting practices. In a global economy, discerning accounting firms know the value in understanding financial reporting standards beyond their own countries. International Financial Reporting Standards (IFRS) are already recognized by many international bodies, including the European Union, Russia, Cooperation Council for the Arab States of the Gulf, Pakistan, India, Hong Kong, South Africa and Australia. Recently, the SEC removed the requirement for foreign private issuers reporting under IFRS to reconcile their financial statements to U.S. GAAP.


This impending development signifies an important shift in the acceptance of IFRS on a national and international level. As a leading accounting firm, Marcum is embracing the opportunity to offer clients access to top quality advice with respect to IFRS. MarcumAsia is experienced in auditing financial statements prepared in accordance with IFRS and consolidating foreign subsidiaries that have been prepared on IFRS for statutory audit purposes in the local jurisdiction.

With offices in China, MarcumAsia is poised to support international clients eager to operate their businesses in the United States or vice versa and to help educate them through the complex regulations regarding such ventures.
