BlackRock Power of Attorney: key Provisions and Implications

This document outlines a power of attorney granted by BlackRock,Inc. dated November 30, 2011, and executed on July 10, 2012. It details the scope of authority granted and the conditions governing its validity. This analysis will break down the key provisions and their implications.

Overview of the Power of Attorney

The power of attorney allows BlackRock, Inc. to appoint attorney(s)-in-fact to act on its behalf. The document doesn’t specify the subject matter of the power of attorney within the provided excerpt, but it establishes the duration and termination conditions for the granted authority.

Key Provisions

Effective Date and Duration

The power of attorney is explicitly stated to be valid “from the date hereof,” meaning November 30, 2011. Tho, the document was executed on July 10, 2012. This suggests the power of attorney was prepared in advance but formally put into effect with the signature date. It remains in full force and effect until one of two conditions is met:

• Revocation by BlackRock: The company can terminate the power of attorney at any time by providing written notice.
• Employment Status of Attorney-in-Fact: For each individual attorney-in-fact named, the power of attorney terminates when that person ceases to be an employee of BlackRock, Inc. or one of its affiliates.

Signatory Information

The power of attorney is signed by Chris Leavy, holding the title of Chief Investment Officer at BlackRock, Inc. This indicates the authority to grant such a power of attorney resided within the investment leadership of the company at the time.

Implications of the Termination clause

The clause tying the power of attorney’s validity to the employment status of the attorney-in-fact is meaningful. It ensures that individuals acting on BlackRock’s behalf retain the necessary authorization only while remaining within the company’s structure. This provides a built-in mechanism for controlling and limiting the scope of delegated authority. When an employee leaves the company, their ability to act under this power of attorney automatically ends, requiring a new appointment if continued representation is needed.

BlackRock, Inc. – Company Background

BlackRock, Inc. (https://www.blackrock.com/) is a multinational investment management corporation based in New York City. As of December 2025, it is the world’s largest asset manager, with trillions of dollars in assets under management. BlackRock provides investment, advisory, and technology services to institutional and retail clients worldwide. Understanding the scale and scope of BlackRock’s operations is crucial when considering the implications of a power of attorney granted by the firm.

Frequently Asked Questions (FAQ)

What is a Power of Attorney?

A power of attorney is a legal document that gives one person (the agent or attorney-in-fact) the authority to act on behalf of another person (the principal). This authority can be broad or limited to specific tasks.

What does “affiliate” mean in this context?

In this context, “affiliate” refers to companies that are related to BlackRock, inc. through ownership or control. This could include subsidiaries or companies with a significant investment from BlackRock.

is this power of attorney still valid today?

Without further information, it’s impractical to definitively say if this specific power of attorney is still valid. It would be valid unless it was revoked in writing by BlackRock or the attorney-in-fact ceased employment with BlackRock or its affiliates. Given the date, it is likely that this specific instance has been superseded by newer documentation.
