"Considering the magnitude of the decline in sales and production, I am very pleased with our performance in the first quarter. We did a good job managing costs and made even more progress on inventory reduction. Operating cash flow was a highlight in the quarter and improved nearly $900 million from the first quarter of 2012. Better cash flow and the strength of our balance sheet are enabling us to resume stock repurchases," said Caterpillar Chairman and Chief Executive Officer Doug Oberhelman.
