Thank you for your interest in a complimentary validation analysis of your recent SEC Interactive Data filing. UBmatrix is the industry's most recognized name when it comes to processing XBRL, whether for regulatory bodies like the U.S. SEC and FDIC, or filing companies like yours. UBmatrix Processing Engine is responsible for the output contained in this report and is a key component inside each of our XBRL software products.

Contained in your analysis are the following validation reports:

• XBRL Validation Report - Each Interactive Data filing must at a minimum be valid XML and XBRL.  The XBRL Validation report lists any errors or inconsistencies found in the extension taxonomy or the XBRL instance document.

• Basic Calculation Trace Report - Together, the US GAAP taxonomy and your extension taxonomy govern the relationship of one element to another. Where items in the taxonomy are supposed to sum together to equal another (e.g., total assets should equal the sum of current assets and non-current assets), UBmatrix Processing Engine tests an instance document to ensure they do.  The Basic Calculation Trace Report shows the results of this validation.

• Detailed Calculation Trace Report - This report offers a more granular look at the Calculation Trace, showing calculation roll-ups all the way up the taxonomy hierarchy, even when a value wasn't explicitly reported at that level.  This report is helpful in tracing roll-up errors.

• SEC Public Validation Criteria Report - In September 2008 the SEC published a list of submission criteria for Interactive Data reports called the "Pubic Validation Criteria".  (View the criteria)  Using UBmatrix Processing Engine 3.5 we have designed a set of XBRL Formulas that test the SEC's criteria and produce the enclosed report.
