The Business Software Alliance (BSA)‘s calculation method compares two sets of data – the number of new software units installed (based on hardware shipments and software load), and the legal supply of new software units. The amount of pirated software is equal to the difference between paid-for or legitimate packaged software units and the total software base. The piracy rate is the percentage of the total packaged software base that is pirated.
The total amount of software, legitimate and pirated, installed during the year (the total software base) is obtained by multiplying the number of new hardware units and the number of existing hardware units getting new software by their respective software loads.
Hardware shipments are determined from tracking data on 60+ countries that IDC collects as a matter of routine. For the additional 30+ countries and markets, the data was either collected in-country or modeled regionally out of our restof- region estimates. The basic tracking data is generated from suppliers, including local suppliers. Similarly, the hardwareinstalled base is based on this tracking data.
The software load is the amount of software units installed and/or pre-installed (OEM) on the computers during the year. To obtain the number of software units for each type of hardware platform, including those running software on Windows and those running software on non-Windows operating systems, IDC surveyed consumers and business in 15 countries: China, Malaysia, Taiwan, Spain, Romania, Brazil, Bolivia, Chile, Colombia, Mexico, Costa Rica, Dominican Republic, Guatemala, Kuwait, and the United States. The results of these surveys were used to populate our input models for the other countries. Within software load, IDC accounted for:
• Software running on new computers
• New software running on existing computers
• Software obtained from retired computers
• Software obtained for free as shareware or open source
• Software that runs on Windows and non-Windows OS
Legitimate software shipments are determined by dividing the software revenues in a country by the average system value (ASV) for that country. Software revenues are captured annually in 60+ countries by IDC software analysts around the world. Revenues are gathered from interviews with suppliers in the country and cross-checked with with global numbers and financial statements. For the countries not normally covered by IDC, the data were either collected in-country or modeled regionally out of our rest-of-region estimates. Software revenues are gathered by type – such as application, infrastructure, and development tools – and by software running on Windows and non-Windows operating systems. It was also allocated to software running on new systems bought during the year and on systems that were already in place.
ASVs are estimated country-by-country by country and regional analysts for five software categories (e.g., collaboration, office, security, OS, other) for each hardware type and Windows and non-Windows software. Prices were gathered from IDC’s pricing trackers, local research, and interviews with the channel. They included adjusting for OEM and channel-loaded software, as well as software from local suppliers. ASVs were gathered in the appropriate currency depending on how the country analysts collected software revenues.

Метод подсчета BSA состоит в сравнении двух наборов данных - вмененного числа установленных программ (software units), вычисленное на основе числа проданных компьютеров и среднестатистического количества программ на компьютере, и числа “законных” новых программ. Разница между этими величинами считается количеством “пиратских программ”. Отношение пиратских программ к вмененному обществу количеству программ есть “коэффицент пиратства”.

Далее, практически открытым текстом (просто несколько запутанно для беглого читателя) рассказывается, что во вмененное количество программ входит все-все - новый софт, старый софт, OEM, свободный софт, разнообразная фриварь и шароварь, самописные программы. В то время как число “законно приобретенных” программ вычисляется путем деления заявленных прибылей проприетарных софтоторговцев (которые, гм, далеко не всегда точны) на каталожные цены их софта (по которым, как известно, покупают только растяпы).
