Methodology

BizMiner uses an industry classification system based on the 4-digit Standard Industrial Classification
system. However, our system is much more granular, detailing about 10,000-17,000 lines of business
in various report series. This system also allows us to present a much more in-depth level of trend
detail than the current NAICS system used by the US and Canadian governments. It is most effective in
developing industry trends, snapshots, experience-based forecasts and averages.

Statistics in our reports are always based on firms that identify a particular classification as their
primary line of business. Not every business identifies beyond a Major Industry (2-digit) and Detailed
Industry (4-digit) classification; not every business selects a more detailed line of business as its
primary classification. This is important for researchers assessing market volume, which in our reports
is based on businesses primarily in a given classification, and does not include sales data for firms
which may operate this type of business as a secondary or tertiary line.

BizMiner's financial analysis series utilize industry-specific base data in conjunction with tested
projections and algorithms to create a "typical" analysis for those industry segments for which complete
detailed data may not be available. In particular, detailed business segment Industry Financial series
asset line items are blended with the closest four digit industry segment. In our financial analysis series,
projections which condition industry specific metrics are applied to expense and liability line item
calculations for some highly granular industry segments.
