What Makes It Challenging to Compare AUM From Different Countries?

Assets Under Management (AUM) is a prominent financial metric, representing the total market value of investments a firm or individual manages for clients. It indicates an investment manager’s scale and influence. While AUM appears to be a straightforward measure, direct comparisons of AUM figures across different countries present significant challenges due to varying interpretations, methodologies, and regulatory landscapes.

Defining Assets Under Management

The definition of Assets Under Management (AUM) can vary significantly across financial institutions and countries, making direct comparisons difficult. AUM generally refers to the total value of financial assets managed by an entity, such as a mutual fund, venture capital firm, or investment advisor, for clients. The precise components included in this calculation are not universally standardized. Some firms may include bank deposits, mutual funds, and cash in their AUM computations, while others restrict it to discretionary funds that investors have explicitly given an advisor to trade on their behalf.

A key distinction arises between discretionary and non-discretionary assets. Discretionary assets are those where the manager has full authority to make investment decisions and execute trades without seeking client approval for each transaction. In contrast, non-discretionary assets, sometimes referred to as “assets under advisement” (AUA), involve the advisor providing guidance or recommendations, but the ultimate decision-making power and trading authority remain with the client. While AUM typically focuses on assets where the manager has direct control, AUA encompasses assets where advice is provided without direct management.

Further complexities arise concerning the inclusion of gross versus net assets in AUM calculations. Gross assets represent the total value of assets before any deductions, while net assets account for liabilities. Some AUM calculations might include assets acquired through leverage, which are investments made with borrowed money, potentially inflating the reported figure. For example, a firm might include the full notional value of derivatives in its gross AUM calculation. Conversely, other firms may only consider the net asset value, which is the asset value minus any debt used for acquisition.

Valuation and Accounting Methodologies

The methods used to value assets within AUM, coupled with diverse national accounting standards, introduce another layer of complexity to international comparisons. Assets are often valued using either fair value accounting or historical cost. Fair value accounting aims to reflect an asset’s current market price. Conversely, historical cost accounting records assets at their original purchase price. The choice between these methods directly impacts the reported AUM.

Fair value measurements themselves are further categorized into a three-level hierarchy, based on the observability of inputs used in the valuation. Level 1 inputs are unadjusted quoted prices in active markets for identical assets, such as publicly traded stocks. Level 2 inputs are observable but not directly quoted prices for identical assets, including prices for similar assets or observable market data. Level 3 inputs are the least observable and rely on unobservable data and management assumptions, often used for illiquid or unique assets. Reliance on Level 2 or Level 3 inputs can introduce subjectivity and variations in valuation, as different assumptions or models might be used, leading to different reported AUM values for the same underlying assets.

Accounting standards adopted by different countries influence how AUM is recognized, measured, and presented. The United States primarily follows U.S. Generally Accepted Accounting Principles (GAAP), while many other countries use International Financial Reporting Standards (IFRS). Both sets of standards have specific rules for asset valuation and financial reporting, but they are not identical. For instance, while both GAAP and IFRS incorporate fair value principles and similar fair value hierarchies, their application details or specific recognition criteria can differ. These variations mean that a firm operating under U.S. GAAP might report AUM differently from a firm operating under IFRS, even with the same portfolio of assets.

Regulatory and Reporting Discrepancies

Each country’s financial regulators establish specific rules regarding what information asset managers must report, how frequently they must report it, and the level of detail required. For example, in the United States, investment advisors managing over $25 million in AUM must register with state securities administrators, while those managing over $100 million must register with the Securities and Exchange Commission (SEC) by filing a Form ADV. This form requires detailed information about regulatory AUM, including client types, and is reported on a gross basis.

The frequency of reporting also differs, with some jurisdictions requiring quarterly or even monthly updates, while others may only mandate annual reporting. For instance, hedge funds in the U.S. with at least $150 million in AUM must file Form PF, with smaller funds filing annually and larger qualifying funds (over $500 million AUM) filing quarterly with more granular detail. In Europe, the Alternative Investment Fund Managers Directive (AIFMD) dictates reporting obligations based on AUM thresholds, with annual, semi-annual, or quarterly reporting depending on whether aggregate AUM exceeds certain amounts. These disparate reporting schedules and specific data requirements mean AUM figures from different regions may not align in timeliness or granularity.

Licensing requirements and oversight bodies also contribute to the lack of comparability. Obtaining an asset management license is a mandatory step for firms managing investor funds, but the conditions vary by jurisdiction. These conditions can include capital requirements, qualifications for key personnel, and the establishment of compliance mechanisms. The diverse regulatory oversight and compliance frameworks complicate direct comparisons between firms operating under different national regulations.

Economic and Market Dynamics

Economic and market factors also complicate the comparison of Assets Under Management across countries. Currency exchange rates are a primary influence, particularly when converting AUM figures from local currencies to a common reporting currency, such as the U.S. dollar. Fluctuations in exchange rates can materially alter the reported AUM, creating an appearance of growth or decline that does not reflect actual investment performance or capital flows. For example, if a U.S.-based firm manages assets denominated in euros, a weakening euro against the dollar would reduce the reported dollar-denominated AUM, even if the underlying euro-denominated assets maintained their value or grew.

Beyond currency impacts, the unique characteristics of different national markets also shape the composition and size of reported AUM. Market conditions, economic indicators like interest rates and inflation, and geopolitical events can all influence asset prices and, consequently, AUM. For example, a country with a highly developed bond market might see a larger proportion of its AUM allocated to fixed income securities compared to a market where equities are the dominant asset class. The prevalence of certain investment vehicles, such as mutual funds, hedge funds, or private equity funds, varies globally. Different investor behaviors and preferences for specific asset classes or investment strategies within a country can lead to distinct AUM compositions.
