"The documented mess in our Russian shopping centre company is completely unacceptable. I have been too optimistic. It is shocking and deplorable that we have wandered off course," Kamprad said in a statement on Friday.
"I realise that I have a moral responsibility in this. I am convinced that Ikea can also contribute to a better life for the many people in Russia in the future," he added.
Over the years, Kamprad has actively supported and shown a personal interest in the company's Russian operations and did his best to encourage rapid expansion of shopping centres with Ikea stores in Russia.
The company's unsuccessful venture into Russia concerns its Ikea shopping center company in Russia, or Ikea Mos. After several external parties conducted a substantial review of Ikea's operations in Russia, the company decided to appoint a new CEO on October 1st.
"We see great potential in the Russian market and are here to stay. We now need to do our homework and my focus is to build up a strong Ikea Mos from Ikea values," new Ikea Mos CEO Per Wendschlag said in a statement on Friday.
Audit work was performed by external experts in accounting and engineering, including KPMG, Ernst & Young, PriceWaterhouseCoopers, Sweco and Cowi in addition to internal investigations conducted by Ikea.
The shortcomings include serious problems at some of the shopping centres' buildings, lack of permission for operations, poor corporate governance and weaknesses in internal controls and poor personnel management.
Allegations of unethical business behaviour with third parties and complex legal disputes regarding diesel equipment and electricity supply in St. Peterburg, which have since been resolved, also surfaced during the investigation.
Ikea operates 12 shopping centres and 12 stores in Russia, with another two stores in the pipeline. The company emphasised that the country is an important market for Ikea, with great potential in retail trade, purchasing and manufacturing.
