On 15 February 2016, the audit and business advisory firm Grant Thornton Baltic OÜ acquired Interna OÜ, which is also known as siseaudiitor.ee. By taking this step, Grant Thornton Baltic will strengthen its capability for offering internal audit service in both the private and public sector as well as in conducting audits.
Managing partner of Grant Thornton Rimess Baltic Mati Nõmmiste spoke about the reasons for acquiring Interna: “We sensed that there was demand on the market and among our clients for internal audit services. Trainings in this field are undoubtedly important, and Interna has been a successful organiser of these. In analysing our product portfolio, we found that Interna’s services were a very good match with our existing services and so we started pursuing the acquisition. We’re sure that all parties will stand to gain from this union. It’s a growing service sector. Together, we will work even better and we’ll be stronger.”
Siiri Antsmäe, the former owner of Interna OÜ and now the head of Grant Thornton Baltic’s internal audit division, says the change in ownership will make it possible to offer even more professional, more encompassing internal audit service. “In addition, a superb opportunity has come up to offer internal audit services within the Grant Thornton Group and in other countries,” she said.
Grant Thornton Baltic has established an internal audit department within the company, which includes four CGAP internal auditors and one with a CIA certificate. The services offered include:
- compliance audits
- performance audits (including ISO)
- management audits
- risk assessment and risk management systems
- evaluation and improvement of internal control systems
- identifying risks of fraud and giving advice for preventing conflicts of interest
- financial audits
- audits of European Union projects
- trainings for internal auditors, accounting specialist etc
Founded in 1992 as Rimess OÜ, Grant Thornton Baltic is one of the leading providers of audit, accounting, tax, legal, finance and business advisory services in the Baltics. Grant Thornton Baltic operates in Estonia, Latvia and Lithuania and is managed by local partners, which translates into a thorough knowledge of the particularities of each country and market. In 2012, the company joined the Grant Thornton network, represented in more than 130 countries and having more than 40,000 employees, conferring the advantages of global scale.
Interna OÜ was founded in 2006 and the company operated under the name siseaudiitor.ee. It was Estonia’s only specialized provider of internal audit service. Among other clients, siseaudiitor.ee is a provider of internal audit services to ministries, government institutions, the European Commission and private sector companies, including companies supervised by the Financial Supervision Authority.
