HIGHLAND HEIGHTS, Ky. (AP) â¿¿ General Cable will spend $185 million in cash to acquire Alcan Cable, the wire and cable business of mining company Rio Tinto PLC. Based on current metal prices, General Cable said it expects the addition of Alcan to boost its annual revenue by between $650 million and $700 million and increase value for shareholders in the near term.

General Cable, based in Highland Heights, Ky., said it plans to use existing financing to fund the deal, which is expected to close in the second half of 2012. Shares of General Cable Corp. rose $1.96 to $29.02 in midday trading.
