Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | NOTE 7. Commitments and Contingencies Factoring The Company maintains arrangements under which eligible accounts receivable in Japan are sold without recourse to unrelated third-party financial institutions. The Company sold $20,639 of receivables during the nine months ended September 30, 2023. These receivables were not included in the Condensed Consolidated Balance Sheets as the criteria for sale treatment had been met. There were no material gains or losses on the sale of such receivables. There were no amounts due from such third-party financial institutions at September 30, 2023. Intellectual Property Indemnification Obligations The Company has entered into agreements with customers that include limited intellectual property indemnification obligations that are customary in the industry. These guarantees generally require the Company to compensate the other party for certain damages and costs incurred as a result of third-party intellectual property claims arising from these transactions. The nature of the intellectual property indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its customers. Historically, the Company has not made any indemnification payments under such agreements and no amount has been accrued in the accompanying Condensed Consolidated Financial Statements with respect to these indemnification guarantees. Warranty Reserves The Company generally provides a warranty on its products for a period of 12 to 14 months against defects in material and workmanship. The Company estimates the costs that may be incurred during the warranty period and records a liability in the amount of such costs at the time revenue is recognized. The Company’s estimate is based primarily on historical experience. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Warranty provisions are generally related to current period sales. Settlements of warranty reserves are generally associated with sales that occurred during the 12 to 14 months prior to the period-end. Changes in the Company’s warranty reserves are as follows:
|  | Nine Months Ended |

|  | 2023 |  |  | 2022 |
Balance, beginning of the period |  | $ | 11,830 |  |  | $ | 9,682 |

Usage |  |  | (9,311 | ) |  |  | (9,076 | )
Balance, end of the period |  | $ | 9,189 |  |  | $ | 11,894 |
Warranty reserves are reported in the Condensed Consolidated Balance Sheets under the captions “Accrued liabilities” and “Other non-current liabilities.” Legal Matters From time to time, the Company is subject to legal proceedings and claims in the ordinary course of business. The following reflects an overview of the material developments with regard to the Company’s pending material legal proceedings. Optical Solutions Inc. v. Nanometrics Incorporated (Case No. 18-cv-00417-BLF): On August 2, 2017, Nanometrics was named as defendant in a complaint filed by Optical Solutions, Inc. (“OSI”) in New Hampshire Superior Court (the “OSI Action”). OSI’s complaint alleged claims arising from a purchase contract between OSI and Nanometrics. The relief sought was the award of damages in an amount to be proven at trial, attorney’s fees and costs, and such other relief that the court deemed just and proper. The OSI Action was subsequently removed to the United States District Court for the District of New Hampshire and then transferred to the United States District Court for the Northern District of California (the “Northern District of California”). On December 20, 2017, Nanometrics filed its own complaint against OSI in the California Superior Court for the County of Santa Clara alleging claims arising from OSI’s breach of certain purchase orders (the “Nanometrics Action”). The relief sought was the award of damages in an amount to be proven at trial, including pre- and post-judgment interest, punitive damages, restitution for benefits unjustly received by OSI, attorney’s fees and costs, and such other relief the court deemed just and proper. The Nanometrics Action was later removed to the Northern District of California and then consolidated with the OSI Action. On July 7, 2020, after the Northern District of California granted the Company’s motion to dismiss with prejudice with regard to two of OSI’s claims and dismissed two other claims asserted by OSI with leave to amend, OSI filed a Fourth Amended Complaint. On August 14, 2020, the Company filed a motion to dismiss one of the two remaining claims. On December 1, 2020, the Northern District of California denied the Company’s motion and as a result the Company filed its Answer in this matter on December 22, 2020. Discovery is now closed. On March 1, 2023, the Company filed a motion for summary judgment, and the hearing on that motion took place on June 29, 2023. On August 3, 2023, the Northern District of California denied the Company’s motion for summary judgment. The trial date is set for December 4, 2023. At the time of filing of this Quarterly Report on Form 10-Q (this “Form 10-Q”), the loss contingency in this matter is remote and the Company does not anticipate the outcome of the matter to have a material impact on its financial position, results of operations, or cash flows. Line of Credit The Company has a credit agreement with a bank that provides for a line of credit which is secured by the marketable securities the Company has with the bank. The Company is permitted to borrow up to 70% of the value of eligible securities held at the time the line of credit is accessed. The available line of credit as of September 30, 2023 was approximately $100.0 million with an available interest rate of 7.0%. The credit agreement is available to the Company until such time that either party terminates the arrangement at their discretion. The Company has not utilized the line of credit as of the date of this filing.
