Caterpillar Inc. CEO and Chairman, Doug Oberhelman, discussed the acquisition of ERA Mining Machinery Ltd., a maker of roof supports for coal mines, acquired in June 2012 for $700 million. The acquisition was "botched" said Oberhelman, leading to the $580 million writedown for the 4th quarter of 2012 and the 55% drop in profits. Former managers of ERA misled Caterpillar about the condition of the business, and in Obherhelman's words "fabricated documentation to cover their tracks." Caterpillar later found inaccurate inventory data and improper revenue recognition. The move to acquire ERA Machinery was an effort to increase sales of mining equipment in China, the world's largest coal producer. As in the Autonomy acquisition by H-P the diligence in checking accounting and other data failed. Caterpillar lowered its forecast for 2013 based on slower growth in mining and decline in investment by mining companies. Mining companies are seeing management turnover over overextended mining projects that went sour. Revenue for 2013 is forecast at between $60 billion and $68 billion, compared to $65.88 billion in 2012. Analysts see risks in the forecast because mining equipment orders may not accelerate till 2015. Mining equipment forms a bigger part of Caterpillar sales and sales growth than construction machinery- sales of mining equipment increased by 14% to $5.78 billion in the 4th quarter 2012, even as sales of construction machinery declined 25% to $4.03 billion. In the U.S. construction machinery sales declined 17% to $1.45 billion in the 4th quarter 2012....
