Microsoft's OpenAI Dealings Lack Investor Transparency
Imagine Microsoft is like a big piggy bank that invests in other companies.
One company it invested in is OpenAI, which makes the ChatGPT.
When a company invests in another, it has to tell everyone exactly how much money is involved and how it affects its own piggy bank.
Microsoft is saying its investment in OpenAI is like owning a big chunk of it.
But when Microsoft tells its own piggy bank investors about this deal, it's not sharing all the details.
It mentions some losses and that OpenAI will buy a lot of computer services from Microsoft.
However, it doesn't fully explain how these deals change its own money numbers.
Investors think this is important because the OpenAI deal is worth a lot of money and helps Microsoft become more valuable.
They want to know if the deal is fair and how it truly impacts Microsoft's money.
Microsoft's financial reports identify OpenAI as an equity-method investment, implying significant influence and related-party status.
Investors are concerned about Microsoft's lack of comprehensive related-party disclosures regarding its extensive dealings with OpenAI.
Microsoft reported $4.1 billion in losses from OpenAI in the last quarter, representing 12% of its pretax profit.
OpenAI has agreed to purchase $250 billion in Microsoft's cloud-computing services, though timing and funding details are unspecified.
While Microsoft states its filings comply with accounting principles, analysts argue the disclosures do not fully reveal the material financial impact of the OpenAI relationship.

Investor/Analyst Concerns
Microsoft's Stance
Disclosure of Related-Party Transactions
Investor/Analyst Concerns
Microsoft should provide more comprehensive disclosures about its transactions with OpenAI, an equity-method investment, to allow investors to understand the financial statement effects.
Microsoft's Stance
Microsoft's financial statements fully comply with generally accepted accounting principles and are audited by an independent firm. The company declined to comment further on specific questions.
Materiality of OpenAI Investment
Investor/Analyst Concerns
The dealings and OpenAI investment are material due to their significant financial implications ($135 billion valuation) and strategic importance to Microsoft's market value, necessitating detailed related-party disclosures.
Microsoft's Stance
Microsoft has provided some new details, including a $4.1 billion loss from OpenAI and an agreement for OpenAI to buy $250 billion in cloud services, indicating they are addressing disclosures as required.
Clarity on Financial Reporting
Investor/Analyst Concerns
The discrepancy between OpenAI's market value ($135 billion) and Microsoft's carrying value for its stake ($1.8 billion as of Sept. 30, down from $6 billion) highlights the need for clearer reporting on the investment's true financial impact.
Microsoft's Stance
The carrying value reflects original investments adjusted for proportionate share of losses, consistent with equity-method accounting. The company did not disclose the carrying amount for the OpenAI stake separately in its quarterly report.
