our continued investments in research and development and through targeted acquisitions in order to broaden our Oracle Cloud offerings. For example, our Oracle Cloud Software-as-a-Service offerings, including our sales, marketing, customer service, financials, project management, human capital and talent management cloud solutions, among others, enable us to provide IT functionality that customers can use to manage critical business functions in a rapidly deployable delivery model with lower upfront customer investment. Certain of our enterprise-grade cloud computing offerings include infrastructure based upon our Oracle Engineered Systems, including our Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud and Oracle SuperCluster products, among others. We designed our Oracle Engineered Systems to combine certain of our hardware and software offerings to increase computing performance relative to our competitors’ products, creating cost efficiencies, time savings and operational cost advantages for our customers. Our Oracle Engineered Systems provide the core infrastructure for our own on-premise IT data centers and those of our customers, and for cloud IT environments, including our own Oracle Cloud services, our partners’ cloud services and our customers’ cloud environments. We also continue to demonstrate our commitment to customer choice through ongoing enhancements to our Oracle E-Business Suite, Siebel, PeopleSoft and JD Edwards application software products and services, amongst others.

We believe that an active acquisition program is another important element of our corporate strategy as it enhances the products and services that we can offer to customers, expands our customer base, provides greater scale to accelerate innovation, grows our revenues and earnings and increases stockholder value. In recent years, we have invested billions of dollars to acquire a number of companies, products, services and technologies that add to, are complementary to, or have otherwise enhanced our existing offerings. We expect to continue to acquire companies, products, services and technologies to further our corporate strategy.

We are organized into three businesses—software and cloud, hardware systems and services—which are further divided into certain operating segments. Each of our businesses and operating segments has unique characteristics and faces different opportunities and challenges. Although we report our actual results in U.S. Dollars, we conduct a significant number of transactions in currencies other than U.S. Dollars. Therefore, we present constant currency information to provide a framework for assessing how our underlying businesses performed excluding the effects of foreign currency rate fluctuations. Our cloud infrastructure-as-a-service segment was established during our fiscal quarter ended May 31, 2014. Our fiscal 2014 results, and historical results for fiscal 2013 and 2012, reflect this new segment structure and will continue prospectively in our future filings.
