Commitments and Contingencies Disclosure [Abstract]

Note 10. Commitments and Contingencies

Litigation: We are a party to legal proceedings and claims which arise during the ordinary course of business.

As of October 31, 2020 and May 2, 2020, $2,166 and $2,072, respectively, were included in the "Accrued expenses" line item in our condensed consolidated balance sheets for the probable and reasonably estimated cost to settle a patent litigation claim.

For other unresolved legal proceedings or claims, we do not believe there is a reasonable probability that any material loss will be incurred. Accordingly, no material accrual or disclosure of a potential range of loss has been made related to these matters. We do not expect the ultimate liability of these unresolved legal proceedings or claims to have a material effect on our financial position, liquidity or capital resources.

Warranties: Changes in our warranty obligation for the six months ended October 31, 2020 consisted of the following:



	October 31, 2020
Beginning accrued warranty obligations	$	25,624
Warranties issued during the period	5,001
Settlements made during the period	(2,817		)
Changes in accrued warranty obligations for pre-existing warranties during the period, including expirations	(1,208		)
Ending accrued warranty obligations	$	26,600

Performance guarantees: We have entered into standby letters of credit, bank guarantees and surety bonds with financial institutions relating to the guarantee of our future performance on contracts, primarily construction-type contracts. As of October 31, 2020, we had outstanding letters of credit, bank guarantees and surety bonds in the amount of $6,853, $3,122 and $31,314, respectively. Performance guarantees are issued to certain customers to guarantee the operation and installation of the equipment and our ability to complete a contract. These performance guarantees have various terms but are generally one year. We enter into written agreements with our customers, and those agreements often contain indemnification provisions that require us to make the customer whole if certain acts or omissions by us cause the customer financial loss. We make efforts to negotiate reasonable caps and limitations on the recovery of such damages. As of October 31, 2020, we were not aware of any indemnification claim from a customer.
