14. | BUSINESS SEGMENTS
ASC Topic 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of a reporting entity, the operating results of which are reviewed regularly by the chief operating decision maker (“CODM”) to make decisions about resource allocation and to assess performance. Our CODM is our Chief Executive Officer. Our operating businesses are organized based on the nature of markets. The SBS segment comprises our core semiconductor back-end equipment manufacturing and testing operations that serve the semiconductor industry. Our value-added distribution business, along with our services and equipment manufacturing operations that serve various industries are being reported together in our IE segment. A detailed description of our operating segments as of September 30, 2025 can be found in the overview section of Item 2 of this Quarterly Report, entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations". A mapping of our previous presentation and the new segments is presented below:
● | Manufacturing – Manufacturing of equipment that solely serves the back-end processes of the semiconductor industry is presented under the SBS segment, and manufacturing of equipment that serves various industries is presented under the IE segment.
● | Testing Services – Testing services are presented under the SBS segment.
● | Distribution – Value-added distribution of burn-in test related equipment is presented under the SBS segment, and value-added distribution of other electronic products is presented under the IE segment.
● | Real estate – Real-estate segment relates to real estate investments made in ChongQing, China. When identifying reportable segments, management evaluates the contribution of each segment to the overall business strategy and whether the segment reported provides meaningful information to users about the Company’s performance and prospects. Revenue from the real-estate segment has been below 1% of total revenue in the past five fiscal years due to the negative real-estate environment in China.
Our CODM uses total revenue, gross profit, operating income and total assets in assessing segment performance and deciding how to allocate resources. Segment operating income includes corporate allocations. Segment revenue includes sales of equipment and services by our segments. Total intersegment sales were $11 and $36 in the three months ended September 30, 2025 and September 30, 2024 respectively. Certain corporate costs, including those related to legal, information technology, human resources and shared services are allocated to our segments based on their relative revenue, manpower costs and fixed assets. The amounts related to revenue and earnings presented as Others include the results of an immaterial real estate business and includes certain costs incurred at the corporate-level, including the cost of our stock compensation plans not allocated to our reportable segments. Assets presented under Others segment consisted primarily of cash and cash equivalents, prepaid expense and investment properties. The cost of equipment, current year investment in new equipment and depreciation expense is allocated into respective reportable segments based on the primary purpose for which the equipment was acquired. The following segment information is unaudited for the three months ended September 30, 2025, and September 30, 2024: Business Segment Information:

Management periodically evaluates the ongoing contributions of each of its business segments to its current and future revenue and prospects. As a result, it may divest one or more business segments in the future to enable management to concentrate on segments where it anticipates opportunities for future revenue growth, thereby maximizing shareholder value.
