A quiet day on the corporate front. Aberdeen Asset Management has announced it has reached an agreement to acquire 100 per cent of the share capital of Artio Global Investors Inc, a publicly listed asset management holding company that should expand Aberdeen's US business.

The purchase price is approximately $175 million (£112 million) based on a price of $2.75 per share. Artio is apparently debt-free and had net asset value of $141 million (£90 million) and cash and seed investments of $136 million (£87 million) on its balance sheet at 31 December 2012.

The move deepen Aberdeen's distribution network and adds to its existing fixed income capabilities in the US. "The transaction is consistent with Aberdeen's stated strategy to identify suitable, quality businesses to complement the Group's organic growth, " claims Aberdeen.

Next, safety, health and environmental technology group Halma. In an interim the Halma Board expects adjusted profit for the full year to be in line with market expectations. Regional and sector trading patterns reported for the first six months of the financial year have been maintained it says.

Good growth has continued in the USA and Asia whilst tougher trading conditions remain in the UK and Europe. Its Industrial Safety sector performed strongly and Health & Analysis is benefiting from recent acquisitions with "good performances" from Health Optics and Fluid Technology offsetting weakness in Photonics.

"We have maintained," says the company, "strong returns and achieved good cash generation, which provide us with the financial capacity for further acquisitions and investment. We continue to search for opportunities across all of Halma's market sectors."

Finally, Rio Tinto - it recently reported its first net loss, to $US2.99 billion - has appointed Andrew Harding as Iron Ore chief executive, replacing Sam Walsh who became Rio Tinto chief executive in January 2013. Andrew's successor as Copper chief executive is Jean-Sebastien Jacques, formerly Copper president, International Operations says Rio. Both appointments take effect today.

"Andrew's experience across a range of Rio Tinto businesses and countries and his three years on the Executive Committee mean he is ideally placed to run the highest-earning business in the Group," says Rio Tinto.

Walsh himself was appointed last month after the company tumbled into the red with $14.4 billion in write-downs.
