What is the main purpose of this 8-K filing?

The primary purpose of this 8-K filing is to revise certain information previously disclosed in Caterpillar's 2010 Form 10-K. Specifically, it updates the company's reportable business segments and includes revised financial statements and Management's Discussion and Analysis (MD&A) reflecting these segment changes.

Does this filing provide an update on Caterpillar's performance since the end of 2010?

No, this filing primarily revises historical information for the 2010 fiscal year. It explicitly states that it does not update all information for events or developments that occurred subsequent to the 2010 10-K filing. For the most current information, investors should refer to Caterpillar's Form 10-Q for the period ended March 31, 2011, and other 8-K filings made after the 2010 10-K.

What are the key risks mentioned in this filing?

The filing reiterates a broad range of risk factors that could materially affect Caterpillar's future results. These include global and industry-specific economic conditions, government policies, commodity and component price fluctuations, liquidity access for the company and its customers/dealers, political and economic risks from global operations, creditworthiness of customers, the success and integration of acquisitions (specifically mentioning Bucyrus International, Inc.), international trade policies, environmental regulations, and currency fluctuations.

Are there any new financial results reported in this document?

This filing does not present new financial results in the typical sense. Instead, it revises portions of the financial statements and MD&A that were part of the 2010 Form 10-K to align with updated segment reporting. For actual financial performance updates, investors should consult subsequent quarterly (10-Q) and annual (10-K) reports, as well as other 8-K filings.
