RSM has added Nigerian firm SIAO Partners to its network.
SIAO Partners is said to be Nigeria’s fifth largest firm with annual fee income of $3.2m and over 100 staff.
The firm is headquartered in Lagos and has offices in the Federal Capital Territory, Abuja and Ekiti State.
RSM said the firm provides audit, assurance and tax services as well as human resource and general business advisory and compliance services.
SIAO Partners managing partner Ituah Ighodalo said: "With an average of 6% GDP growth rate since 2005, and as Africa’s second largest economy, Nigeria offers significant growth prospects. A growing proportion of our business is now conducted cross-border, and we felt that the time was right to join a well-established international network with the breadth of coverage and the depth of expertise of RSM."
RSM chief executive Jean Stephens said: "I am delighted to welcome SIAO to RSM and am very encouraged about the development of our network in Africa, where we already have strong member firms in Botswana, Kenya, Mauritania, South Africa and Tanzania as well as our North African member firms. "
