By Reuters Staff 2 Min Read SINGAPORE (Reuters) - Jardine Matheson Holdings Ltd on Monday said it plans to buy the remaining 15% of Jardine Strategic Holdings Ltd that it does not already own for about $5.5 billion to simplify the structure of the sprawling Asian conglomerate. Singapore-listed Jardine Matheson, whose businesses include construction, aviation and automotive, has offered to pay $33 in cash for each Jardine Strategic share, representing a premium of 20% to the stock’s closing price on Friday. “This will result in a single holding company with a conventional ownership structure and a further increase in the group’s operational efficiency and financial flexibility,” it said in a statement.
