About the report

Methodology

The PwC Global 100 Software Leaders list is based on corporate financial statements (GAAP-based where applicable), other public sources and estimates for privately held companies, as compiled for PwC by the Global Software Business Strategies Group at IDC.

Due to variances in fiscal years, the results were ‘calendarised’ for 2012, the most recent year for which complete data was available.

Currencies were converted to US dollars using the average historical inter-bank rate for 2012 as the rate of exchange. The historical rates used can be found at www.oanda.com. The table reports the company’s total revenue and revenue from software.

Software revenue includes fees from licenses, maintenance, subscriptions and other software services, including software as a service (SaaS). Total revenue also includes software plus hardware, nonrecurring IT service fees, business process services and other sources.

Consumer gaming companies—Electronic Arts, Activision Blizzard and Nintendo, for example—are not included in this study.

SaaS revenue refers to all revenue derived from the SaaS delivery model, a utility computing environment in which unrelated customers share a common application and infrastructure managed by an independent software vendor or a third-party service provider that typically owns the code or intellectual property. The model provides access to and consumption of software and application functionality built specifically for network delivery and accessed by users over the Internet.

The myriad ‘as a service’ (APPaaS, PaaS, IaaS) offerings—including business application services, databases, software development tools, high-level storage services (backup and archiving), testing as a service, and security as a service—are all included in the category of SaaS.

SaaS revenues do not include software deployed internally by the customer or any packaged software for which a license fee and a maintenance fee are paid. As noted previously, a few hardware-oriented elements of IT cloud services that contain software, such as bulk storage solutions, network services and cloud servers, are not included in the SaaS figures.
