its application. There are also areas in which management’s judgment in selecting among available alternatives would not produce a materially different result. Our senior management has reviewed our critical accounting policies and related disclosures with the Finance and Audit Committee of the Board of Directors.

Revenue Recognition

Our sources of revenues include: (1) software and cloud revenues, including new software licenses revenues earned from granting licenses to use our software products; cloud SaaS and PaaS revenues generated from fees for granting customers access to a broad range of our software and related support offerings on a subscription basis in a secure, standards-based cloud computing environment; cloud IaaS revenues generated from fees for deployment and management offerings for our software and hardware and related IT infrastructure generally on a subscription basis; and software license updates and product support revenues; (2) hardware systems revenues, which include the sale of hardware systems products including computer servers, storage products, networking and data center fabric products, and hardware systems support revenues; and (3) services, which includes software and hardware related services including consulting, advanced customer support and education revenues. Revenues generally are recognized net of any taxes collected from customers and subsequently remitted to governmental authorities.

Revenue Recognition for Software Products and Software Related Services (Software Elements)

New software licenses revenues primarily represent fees earned from granting customers licenses to use our database, middleware and application software and exclude cloud SaaS and PaaS revenues and revenues derived from software license updates, which are included in software license updates and product support revenues. The basis for our new software licenses revenue recognition is substantially governed by the accounting guidance contained in ASC 985-605, Software-Revenue Recognition. We exercise judgment and use estimates in connection with the determination of the amount of software and software related services revenues to be recognized in each accounting period.

For software license arrangements that do not require significant modification or customization of the underlying software, we recognize new software licenses revenues when: (1) we enter into a legally binding arrangement with a customer for the license of software; (2) we deliver the products; (3) the sale price is fixed or determinable and free of contingencies or significant uncertainties; and (4) collection is probable. Revenues that are not recognized at the time of sale because the foregoing conditions are not met, are recognized when those conditions are subsequently met.

Substantially all of our software license arrangements do not include acceptance provisions. However, if acceptance provisions exist as part of public policy, for example, in agreements with government entities where acceptance periods are required by law, or within previously executed terms and conditions that are referenced in the current agreement and are short-term in nature, we
