World: Holcim and Lafarge have begun to formally notify regulators as to how they will tackle antitrust concerns, according to Holcim's CEO Bernard Fontana. The two companies have filed formal notifications, which generally include information on what the combined entity will look like and steps it will take to prevent it from abusing its size, in about two-thirds of the 15 jurisdictions that require a review of the proposed deal. Those include the US, Canada, Mexico, India and Russia, among others.

Fontana said that discussions with the European Union (EU), where the two companies have some of their greatest overlap, were at an 'advanced' stage. He added that he expects formal notification to be made in the summer of 2014. "We are on track," said Fontana, who has run Holcim since 2012. "We will do what we planned to do."

Holcim and France's Lafarge have moved quickly to satisfy regulators since unveiling their proposed transaction, which will create a cement company with combined sales of Euro31.8bn. The deal is expected to face significant challenges from competition authorities. EU antitrust chief Joaquin Almunia has already said that the deal is likely to face an extended probe by his agency.

Fontana said that the list of proposed businesses and plants it would sell in order to satisfy regulators, which it announced recently, would maintain entire businesses that function well and generate the greatest proceeds from the sale process. According to Fontana, Holcim and Lafarge have received more than 100 expressions of interest from potential buyers of the assets.

"We have had marks of interest from all kinds of prospective buyers," said Fontana. He added that potential buyers include private-equity groups and companies in the cement industry, including some from emerging markets. Holcim and Lafarge could also choose to sell some assets via initial public offerings.
