We have operating leases that primarily relate to certain of our facilities, data centers and vehicles. As of May 31, 2020, our operating leases substantially have remaining terms of one year to twelve years, some of which include options to extend and/or terminate the leases.

For fiscal 2020, operating lease expenses totaled $599 million, net of sublease income of $16 million. At May 31, 2020, ROU assets, current lease liabilities and non-current lease liabilities for our operating leases were $2.0 billion, $575 million and $1.5 billion, respectively. We recorded ROU assets of $2.8 billion in exchange for operating lease obligations during the year ended May 31, 2020, which included $1.9 billion for operating leases existing on June 1, 2019 that were recognized upon our initial adoption of Topic 842 and $849 million for operating leases that were contracted during fiscal 2020. Cash paid for amounts included in the measurement of operating lease liabilities was $663 million for year ended May 31, 2020. As of May 31, 2020, the weighted average remaining lease term for operating leases was approximately six years and the weighted average discount rate used for calculating operating lease obligations was 3.2%. As of May 31, 2020, we have $411 million of additional operating lease commitments, primarily for data centers, that commence in fiscal 2021 for terms of one to ten years that are not reflected on our consolidated balance sheet as of May 31, 2020 or in the maturities table below.

In the ordinary course of business, we enter into certain unconditional purchase obligations with our suppliers, which are agreements that are enforceable and legally binding and specify terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the payment. We utilize several external manufacturers to manufacture sub-assemblies for our hardware products and to perform final assembly and testing of finished hardware products. We also obtain individual components for our hardware products from a variety of individual suppliers based on projected demand information. Such purchase commitments are based on our forecasted component and manufacturing requirements and typically provide for fulfillment within agreed upon lead-times and/or commercially standard lead-times for the particular part or product and have been included in the amounts disclosed below. Routine arrangements for other materials and goods that are not related to our external manufacturers and certain other suppliers and that are entered into in the ordinary course of business are not included in the amounts below, as they are generally entered into in order to secure pricing or other negotiated terms and are difficult to quantify in a meaningful way.

As of May 31, 2020, our unconditional purchase and certain other obligations were as follows (in millions):

Fiscal 2021	$	881
Fiscal 2022		66
Fiscal 2023		30
Fiscal 2024		27
Fiscal 2025		23
Thereafter		236
Total	$	1,263

As described in Notes 7 and 10 above, as of May 31, 2020 we have senior notes and other borrowings that mature at various future dates and derivative financial instruments outstanding that we leverage to manage certain risks and exposures.

Our cloud, license and hardware sales agreements generally include certain provisions for indemnifying customers against liabilities if our products infringe a third party’s intellectual property rights. To date, we have not incurred any material costs as a result of such indemnifications and have not accrued any material liabilities related to such obligations in our consolidated financial statements. Certain of our sales agreements also include provisions

indemnifying customers against liabilities in the event we breach confidentiality or service level requirements. It is not possible to determine the maximum potential amount under these indemnification agreements due to our limited and infrequent history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement.

Our Oracle Cloud Services agreements generally include a warranty that the cloud services will be performed in all material respects as defined in the agreement during the service period. Our license and hardware agreements also generally include a warranty that our products will substantially operate as described in the applicable program documentation for a period of one year after delivery. We also warrant that services we perform will be provided in a manner consistent with industry standards for a period of 90 days from performance of the services.

We occasionally are required, for various reasons, to enter into financial guarantees with third parties in the ordinary course of our business including, among others, guarantees related to taxes, import licenses and letters of credit on behalf of parties with whom we conduct business. Such agreements have not had a material effect on our results of operations, financial position or cash flows.

In connection with certain litigation, we posted certain court-mandated surety bonds with a court and entered into related indemnification agreements with each of the surety bond issuing companies. Additional information is provided in Note 17 below.
