​ Operating income (loss) consists of sales less cost of sales, engineering and development expenses, and selling, general and administrative expenses but is not affected by either other income (expense) or by income tax expense (benefit). Non-operating expenses/income consists principally of interest income from transactions with payment terms exceeding one year (see Note 6, “Accounts and Long-Term Receivable” for details) and interest income from money market accounts in fiscal year 2023 year as interest rates have increased significantly, and interest expense primarily from multi-year agreements with vendors (see Note 9, “Accounts payable and other noncurrent liabilities”). All intercompany transactions have been eliminated. The following table lists customers from which the Company derived revenues of 10% or more of total revenues for the three and six months ended March 31, 2023 and 2022.

There were no other customers with more than 10% of total consolidated accounts receivable and long-term receivable as of March 31, 2023.
