Revenue
Management fees
The Company’s management fees are a function of the fee rates charged to clients, which are typically expressed in basis points, and the levels of the Company’s assets under management. The most significant driver of increases or decreases in this average fee rate is changes in the mix of the Company’s assets under management caused by net inflows or outflows in certain asset classes or disproportionate market movements.
Performance fees
The Company’s products subject to performance fees earn these fees upon exceeding high-water mark performance thresholds or outperforming a hurdle rate. Performance fees are recorded in revenues when the contractual performance criteria have been met and when it is probable that a significant reversal of revenue recognized will not occur in future reporting periods.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
