What is the purpose of the 75% test for identifying reportable segments?

The purpose of the 75% test for identifying reportable segments is to ensure that consolidated revenue is significant. This test is part of the criteria set by the Financial Accounting Standards Board (FASB) in the context of segment reporting under ASC 280. The 75% test requires that if a company's external revenue from its reportable segments does not account for at least 75% of the consolidated revenue, additional segments must be identified as reportable segments until the total contribution reaches that 75% threshold.

This approach emphasizes the need for companies to report segments that are significant enough to provide insights into their operations and financial performance. The goal is to ensure that stakeholders have a complete picture of the company's business activities and can make informed decisions. Segment reporting is meant to enhance transparency and provide detailed financial information relevant to various components of the business, which is essential for a thorough understanding of the company’s financial condition and operations.
