Our fiscal year is reported on a 52- or 53-week year ending on the last Friday in April. An additional week is included in the first fiscal quarter approximately every six years to realign fiscal months with calendar months. Fiscal year 2022, ending on April 29, 2022, is a 52-week year, with 13 weeks in each of its quarters. Fiscal year 2021, ended on April 30, 2021 was a 53-week year, with 14 weeks included in its first quarter and 13 weeks in each subsequent quarter.

Segment Change

Effective July 30, 2021, our Chief Operating Decision Maker, who is our Chief Executive Officer, realigned internal reporting and began using financial information for components of our business, organized based on category of product/solution, to evaluate performance and allocate resources. This resulted in the creation of two operating segments and two reportable segments for financial reporting purposes: Public Cloud and Hybrid Cloud.

Public Cloud

NetApp's Public Cloud segment offers a portfolio of products delivered primarily as-a-service, including related support, and made available on the world’s leading clouds. This portfolio includes storage services, cloud automation and optimization services, and cloud infrastructure monitoring services. Public Cloud includes certain reseller arrangements in which the timing of our consideration follows the end user consumption of the reseller services.

Hybrid Cloud

NetApp’s Hybrid Cloud segment offers a portfolio of storage and data management solutions that help customers build and integrate on-premises and private cloud environments. This portfolio is designed to operate with public clouds to unlock the potential of hybrid, multi-cloud operations. Hybrid Cloud is composed of software, hardware, and related support, as well as professional and other services.

Recent Accounting Pronouncements

Although there are several new accounting pronouncements issued or proposed by the FASB that we have adopted or will adopt, as applicable, we do not believe any of these accounting pronouncements had or will have a material impact on our consolidated financial position, results of operations, cash flows or disclosures.
