CPA Exam Tutorial: Reportable Segments on the BAR Section Featuring Microsoft Azure
Catch the audio version of the BAR exam tutorial on my Substack.
Microsoft Azure is one of the largest cloud-computing businesses in the world. It has also been one of Microsoft’s most important growth engines. Yet if you opened Microsoft’s 2026 annual report looking for a standalone Azure income statement, you won’t find one.
You’d find Intelligent Cloud, one of Microsoft’s three reportable segments at the time. Intelligent Cloud included Azure and other cloud services, server products, enterprise support, industry solutions, and other offerings. Microsoft disclosed Intelligent Cloud revenue, expenses, and operating income. It also disclosed a growth rate for “Azure and other cloud services.” But those disclosures didn’t isolate Azure’s revenue, expenses, operating income, or margin.
Why should we care about this? Because a business can be economically significant (e.g. Azure) without being presented as a separate reportable segment.
The accounting question goes beyond whether Azure is large or important. The bigger questions are about how Microsoft’s management organizes the business, what financial information its chief operating decision maker reviews, whether discrete financial information is available, and how the requirements of ASC 280 apply.
What is segment reporting?
Consolidated financial statements combine an entire company into one set of numbers. That’s useful to a degree, but it can also hide the economics of individual businesses.
Imagine placing Azure, server software, support services, and other products into one financial-reporting crockpot. The final number may be accurate in total, but an investor can’t easily determine which ingredient generated the growth, consumed the capital, or produced the margin.
The stakes rise as Microsoft invests heavily in cloud computing and artificial intelligence, which is a capital-intensive move. These businesses require data centers, servers, chips, networking equipment, energy capacity, and other infrastructure before the related revenue is earned. These significant upfront cash outflows, like a trucking company purchasing equipment before it can move the first customer’s freight, are all the more reason transparency in Microsoft’s financial statements is needed.
When Azure’s economics are combined with other businesses, it becomes harder to connect:
Revenue growth to the costs required to produce it
Capital expenditures to a specific business
Depreciation and infrastructure costs to Azure’s margins
Cash outflows to the future returns management expects
Azure’s performance to that of competitors such as Amazon Web Services
Segment information gives CPA candidates and financial statement users a sharper view of the business story.It connects what a company earned to which parts of the business created that return and what resources were required.
Step 1: Identify the operating segments
Under ASC 280, a component of a public entity is an operating segment when all three conditions are met:
It engages in business activities from which it may earn revenue and incur expenses.
Its operating results are regularly reviewed by the chief operating decision maker, or CODM, to assess performance and allocate resources.
Discrete financial information is available.
The CODM is a function rather than automatically a job title. It may be an individual, such as the CEO, or a group. In Microsoft’s FY2026 annual report, the company identified its CEO as the CODM and explained that the CODM reviewed segmented internal profit-and-loss statements and used operating income to allocate resources and assess performance.
That disclosure gives you a direct connection to the management approach in ASC 280: external segment reporting begins with the way management actually sees and manages the business.
CPA Exam Takeaway: Start with the operating segments, then apply the 10% tests (10% of combined revenue or operating profit or assets). The quantitative tests come after the operating segments have been identified and any permitted aggregation has been considered.
Step 2: Determine whether operating segments may be aggregated
Two or more operating segments may be combined when aggregation is consistent with the objective and principles of the standard, the segments have similar economic characteristics, and they are similar in areas such as:
Products and services
Production processes
Types or classes of customers
Distribution methods
Regulatory environments, when applicable
This is a judgment area. Similarity can’t be assumed merely because two businesses use technology or serve some of the same customers.
For exam questions, read the facts carefully. The question may give you operating segments that appear separate but qualify for aggregation before the quantitative tests are applied.
Step 3: Apply the 10% reportability tests
An operating segment is separately reportable if it meets any one of the following quantitative tests.
Revenue test
The segment’s revenue, including external sales and intersegment sales or transfers, is at least 10% of the combined revenue of all operating segments.
CPA exam tip: you could see CPA exam questions that give you P&L numbers by segment then in total and ask you which ones are reportable. Spend some time understanding the 10% reportability rules.
Profit-or-loss test
The absolute amount of the segment’s reported profit or loss is at least 10% of the greater, in absolute amount, of:
The combined profit of all operating segments that reported a profit, or
The combined loss of all operating segments that reported a loss.
The word absolute does important work here. Profitable and loss-producing segments are evaluated on the required absolute-value basis before this test is applied.
Asset test
The segment’s assets are at least 10% of the combined assets of all operating segments.
CPA Exam Takeaway: A segment becomes reportable when it passes any one of the three 10% tests. One test is enough.
Step 4: Apply the 75% external-revenue test
After identifying the reportable segments, add their revenue from external customers.
If that amount is less than 75% of the entity’s consolidated external revenue, additional operating segments must be reported separately, even if they didn’t meet a 10% test, until at least 75% of consolidated external revenue is included in reportable segments.
This is a coverage test. Its purpose is to prevent too much of the company’s external revenue from disappearing into an “all other” category.
Step 5: Understand what gets disclosed
For each reportable segment, a public entity generally provides information that reflects what management uses, including a measure of segment profit or loss and specified revenue, expense, asset, and other information when those amounts are reviewed by or regularly provided to the CODM.
Current ASC 280 requirements also include enhanced disclosures about significant segment expenses that are regularly provided to the CODM and included in the reported measure of segment profit or loss. Public entities must identify the CODM’s title and position and explain how the CODM uses the reported profit-or-loss measure to assess performance and allocate resources.
The entity also reconciles reportable-segment totals to the consolidated financial statements.
Entity-wide disclosures and reportable-segment disclosures serve different purposes. A company may disclose revenue by product or service while presenting the product or service within a broader reportable segment. That distinction frames the Microsoft Azure case.
Microsoft Azure: what investors could see
Microsoft’s FY 2026 annual report presented three reportable segments:
Productivity and Business Processes
Intelligent Cloud
More Personal Computing
For fiscal year 2025, Microsoft reported $106.3 billion of revenue and $44.6 billion of operating income for Intelligent Cloud. The company stated that Intelligent Cloud revenue growth was driven by Azure and disclosed 34% growth for “Azure and other cloud services.”
Azure appeared within Intelligent Cloud alongside server products and enterprise and partner services. The annual report gave users visibility into the broader segment’s revenue, expenses, and operating income, while Azure’s standalone cost structure and operating margin remained within that larger reporting view.
This is the tension: Microsoft could comply with the segment-reporting model while investors still wanted more granular information about its most closely watched cloud business.
AWS vs Azure: a useful comparison
Amazon reports AWS separately. For fiscal year 2025, Amazon disclosed AWS segment sales of $128.7 billion and AWS segment operating income of $45.6 billion.
That lets a financial statement user calculate and analyze AWS’s segment operating margin, compare its performance across periods, and evaluate its contribution to Amazon’s consolidated results.
The comparison highlights the management-approach foundation of segment reporting. Companies organize their businesses differently, provide different information to their CODMs, and reach reportable-segment conclusions based on how management actually reviews performance and allocates resources.
It does show why investors found Amazon’s AWS disclosures more useful for analyzing the standalone economics of cloud computing.
What changed at Microsoft in September 2026
Microsoft has now announced a new financial-reporting structure beginning in fiscal 2027. The company will move from three reportable segments to two:
Agents and Infra
Devices and Consumer
Microsoft also said it will provide quarterly revenue for key businesses, including Azure. The Azure definition will be narrowed by moving certain developer, security, and healthcare cloud offerings into other product categories.
This provides more visibility into Azure revenue while keeping Azure within the broader Agents and Infra segment. The disclosure changes the level of product-level transparency without changing Azure’s reportable-segment presentation.
That gives CPA candidates an especially useful distinction: Product-level revenue disclosure and reportable-segment presentation answer related but separate questions.
Investors will gain a clearer view of Azure’s revenue. A fuller view of Azure’s economics would require additional information about its expense structure, operating income, and operating margin, details that would make comparison to AWS more direct.
What to remember for the BAR Exam
When you see a segment-reporting question, work through it in this order:
Identify the operating segments. Look for business activities, CODM review, and discrete financial information.
Consider aggregation. Determine whether qualifying operating segments may be combined.
Apply all three 10% tests. Revenue, profit or loss, and assets.
Apply the 75% test. Confirm that reportable segments cover at least 75% of consolidated external revenue.
Determine the disclosures. Focus on the information used by or regularly provided to the CODM and the required reconciliations.
Separate segment disclosure from entity-wide disclosure. A product’s revenue may be disclosed without the product becoming a reportable segment.
The bigger lesson
Segment reporting is the accounting bridge between how management runs a company and how investors see it.
Microsoft Azure brings that idea to life. Azure can drive growth, consume enormous amounts of capital, and shape Microsoft’s strategy without appearing as a standalone reportable segment. Microsoft’s new disclosures may make Azure revenue easier to see, but the broader question remains: can financial statement users see enough of the underlying economics to evaluate performance and future cash flows?
That’s the difference between reading the financial statements and understanding the story behind them.
