The Employees Retirement System of the City of St. Louis has filed a derivative action in the Southern District of New York against FS/KKR Advisor, LLC, alleging the investment adviser has inflated asset valuations at FS KKR Capital Corporation to extract excessive management and incentive fees. The complaint, filed July 15, 2026, challenges valuation methodologies, governance practices, and compensation structures under Section 36(b) of the Investment Company Act of 1940. The action raises questions about how private asset managers value illiquid securities and allocate fee-generating income to shareholders.

FSK's Business Structure and Investment Advisory Arrangement

FS KKR Capital Corporation operates as a business development company, or BDC, under the Investment Company Act of 1940. Unlike traditional investment funds that purchase and sell publicly traded securities with transparent market pricing, FSK specializes in holding loans extended to private companies. The valuations of these illiquid private credit instruments must be estimated rather than derived from observable market transactions, creating an inherently subjective process dependent on adviser judgment and methodology.

Under the investment advisory agreement disclosed in the complaint, FS/KKR Advisor manages FSK's portfolio and receives compensation structured as management fees calculated by reference to FSK's gross assets under management and pre-incentive fee net investment income. The complaint alleges this compensation architecture creates a material conflict of interest: when FS/KKR Advisor assigns higher valuations to loans in FSK's portfolio, delays necessary asset write-downs, or recognizes additional non-cash accrued income, the adviser receives correspondingly higher fee payments. This dynamic, the complaint argues, incentivizes the adviser to maintain inflated asset values rather than mark investments to fair value.

Payment-in-Kind Income and Fee Inflation Mechanisms

A substantial portion of FSK's reported investment income consists of payment-in-kind interest, or PIK. In typical loan arrangements, borrowers remit interest payments in cash on a current basis, often monthly or quarterly. Under PIK structures, borrowers instead add accrued interest to the loan's principal balance rather than paying cash currently. This non-cash interest accrual enters FSK's income calculations and directly increases the pre-incentive fee net investment income metric used to compute FS/KKR Advisor's management fees.

The complaint alleges that PIK income creates a structural conflict because FS/KKR Advisor benefits financially when FSK recognizes PIK accruals, yet PIK typically accrues only on loans experiencing cash flow stress or covenant violations. According to the filing, increased PIK at FSK has coincided with elevated loan deferrals and deteriorating portfolio credit quality. The complaint further asserts that PIK accruals have created persistent cash flow shortfalls for FSK, as shareholders receive no corresponding cash distributions tied to non-cash accrued interest. The complaint suggests this arrangement permits FS/KKR Advisor to generate fee income from income that may ultimately prove uncollectible or require significant future write-downs.

Valuation Governance and Conflict-of-Interest Architecture

Under SEC Rule 2a-5 and the Investment Company Act framework, FS/KKR Advisor serves simultaneously as FSK's investment adviser, administrator, and designated valuation agent responsible for determining fair value of portfolio investments. The complaint alleges this consolidated authority structure creates governance vulnerabilities because the same entity that receives fees tied to asset valuations also possesses unilateral authority to establish the valuation methodologies and make individual position-level fair value determinations.

The complaint identifies an independent valuation committee, referred to as the IVP (Independent Valuation Panel), but characterizes its role as limited. The complaint suggests the IVP operates within parameters and methodologies established by FS/KKR Advisor and lacks sufficient independence or technical resources to challenge adviser valuations on a position-by-position basis. This governance structure, the complaint contends, fails to create adequate checks and balances to prevent valuation inflation driven by the adviser's fee incentives. The complaint references SEC enforcement precedent involving valuation abuses at other investment advisers and fund complexes as analogous authority.

Fair Value-to-Amortized Cost Ratio Variability and Asset Quality Indicators

The complaint analyzes FSK's fair value-to-amortized cost ratio, or FV/AC ratio, as a metric to assess whether portfolio valuations track investment performance realistically. Amortized cost represents the original purchase price of an investment adjusted over time for principal repayments and accrued interest. When the FV/AC ratio falls below 1.0, it signals that fair values assigned to investments have declined below their cost basis. Conversely, when FV/AC ratios remain elevated and stable, the adviser is asserting that investments have either appreciated or maintained their original cost values despite market or credit stress.

The complaint alleges that FSK's FV/AC ratio exhibits implausibly low variability despite significant macroeconomic headwinds, interest rate increases, software sector disruption, and rising credit stress in FSK's portfolio. The complaint contends this pattern is inconsistent with realistic valuation discipline and suggests the adviser has delayed or avoided necessary fair value adjustments. The complaint further documents persistent net asset value erosion on a per-share basis even as FS/KKR Advisor reports stable or improving FV/AC metrics, a divergence the complaint characterizes as evidence of valuation practices that do not reflect deteriorating underlying credit conditions.

Kellermeyer Bergensons Services and Position-Level Valuation Examples

The complaint examines a specific portfolio investment in Kellermeyer Bergensons Services as a detailed case study of alleged valuation overstatement and restructuring-driven fee optimization. According to the complaint, FSK held a PIK loan to this borrower that was later subject to a debt restructuring transaction. The complaint contends that FS/KKR Advisor maintained elevated fair values for the Kellermeyer investment despite evidence of borrower distress, loan deferrals, and covenant violations. The complaint then alleges that when restructuring became inevitable, FS/KKR Advisor restructured the loan in a manner that preserved nominal fair values and generated additional fee-eligible accruals rather than immediately recognizing fair value loss.

The complaint identifies additional portfolio investments as exhibiting similar patterns of delayed write-downs and fee-conflicted restructuring activities. The complaint references examples where non-accrual rates in FSK's portfolio have escalated, yet fair valuations have not adjusted proportionally. The complaint further notes instances where fair values assigned to PIK securities have remained above accumulated cost even as cash recovery prospects have diminished. The complaint contends these position-level patterns, taken collectively, demonstrate systematic valuation practices that prioritize fee preservation over fair value discipline.

Market Conditions and Credit Backdrop During the Relevant Period

The complaint situates FSK's recent performance within a broader macroeconomic and credit market context characterized by rising interest rates, economic uncertainty, and sector-specific disruption. The complaint identifies artificial intelligence disruption in the software sector as a material credit headwind affecting a portion of FSK's portfolio. The complaint further references broader market stress indicators and credit spread widening as objective evidence that private credit valuations faced downward pressure during the period covered by the complaint.

The complaint alleges that despite these adverse market conditions, FS/KKR Advisor failed to implement fair value adjustments proportionate to the magnitude of credit deterioration and risk repricing evident in public credit markets. The complaint contends that the adviser's valuation practices during this period demonstrated insufficient responsiveness to objective market signals and deteriorating credit fundamentals. The company did not disclose specific guidance regarding expected future asset valuations or fair value adjustment timing in the materials reviewed by the complaint.

Gartenberg Factor Analysis and Compensation Excessiveness

The complaint invokes the Gartenberg factors, a legal framework established in Tannenbaum v. Zeller and refined in subsequent case law, to evaluate whether FS/KKR Advisor's compensation structure constitutes excessive fees under Section 36(b) of the Investment Company Act. The first Gartenberg factor examines the nature and quality of services rendered, including the complexity of managing a private credit BDC portfolio and the resources dedicated to portfolio management, valuation, and administration. The complaint characterizes the services rendered as standard BDC advisory functions not materially different in complexity from other similarly-sized private credit fund managers.

The second factor addresses profitability to the adviser from FSK's management fees and incentive fees. The complaint asserts that FS/KKR Advisor's compensation from FSK generates high margins and profit levels. The third factor examines fall-out benefits, such as reputational enhancement or ancillary business development value derived from managing FSK. The fourth factor analyzes whether economies of scale are shared with fund investors through fee reductions as assets under management grow. The complaint contends FS/KKR Advisor has not reduced advisory fee rates as FSK's asset base has expanded, retaining the benefit of scale economies rather than passing savings to shareholders. The fifth factor compares FS/KKR Advisor's fee structure to comparable advisers managing similar private credit BDCs, with the complaint asserting that FS/KKR's incentive fee asymmetry magnifies compensation relative to peer benchmarks.

Fiduciary Duty Allegations and Valuation Governance Failures

The complaint alleges that FS/KKR Advisor breached its fiduciary duties owed to FSK and its shareholders by extracting fees substantially in excess of reasonable compensation for services rendered. The complaint contends that fiduciary duty extends not only to fee reasonableness but also to the underlying valuation methodologies and fair value determinations that drive fee calculations. The complaint further alleges that FS/KKR Advisor failed to discharge its fiduciary duty to determine fair value in good faith when it maintained valuations that did not reflect observable market deterioration, credit stress indicators, or adverse changes in portfolio company fundamentals.

The complaint references the FSK Board process and notes that board oversight of adviser compensation did not cure the alleged excessiveness of fees. The complaint suggests that while FSK maintains a Board of Directors that theoretically oversees adviser compensation, the board process failed to identify or challenge valuation inflation and fee-conflicted income recognition practices. The complaint characterizes the board as insufficiently independent or equipped with resources necessary to challenge adviser valuation judgments on a position-by-position basis. The complaint contends that macro and market conditions during the relevant period demanded material write-downs that FS/KKR Advisor systematically failed to implement.

Requested Relief and Legal Framework

The complaint seeks relief under Section 36(b) of the Investment Company Act, which provides a private right of action for investors to recover excessive adviser compensation. Section 36(b) permits recovery of fees found to be so disproportionately large as to constitute a breach of fiduciary duty. The complaint characterizes FS/KKR Advisor's fee structure and valuation practices as meeting this legal standard. The prayer for relief seeks recovery of excess fees paid by FSK to FS/KKR Advisor, though the complaint does not disclose a specific dollar amount sought as damages at this pleading stage.

The complaint further seeks prospective injunctive relief, including reformation of FS/KKR Advisor's compensation structure to align fee calculations with objectively verifiable market benchmarks, implementation of enhanced valuation governance procedures, and independent validation of fair value determinations. The complaint invokes the legal framework of the Investment Company Act, SEC Rule 2a-5 regarding valuation designee authority and responsibilities, and established case law interpreting excessive fee standards. The legal threshold for proving excessive compensation under Section 36(b) requires demonstrating that fees are so disproportionately large relative to the services rendered and comparative industry standards that they constitute a breach of fiduciary duty.

Implications for BDC Valuation and Adviser Governance

The complaint raises systemic questions about valuation governance and fee-conflict management across the broader BDC industry. The complaint's allegations suggest that private credit fund managers operating within a BDC structure may face insufficient constraints on valuation discretion and inadequate penalties for overvaluation when fee incentives are aligned with higher asset values. The complaint's focus on FS/KKR Advisor's simultaneous roles as adviser, administrator, and valuation designee highlights governance vulnerabilities that may extend across the industry when independent valuation oversight is limited or deferential to adviser methodologies.

The complaint also underscores ongoing litigation and regulatory focus on private fund adviser compensation structures and valuation practices. Investment advisers managing illiquid assets face heightened scrutiny regarding valuation discipline, particularly when fee structures create incentives to maintain elevated fair values. The complaint's detailed analysis of PIK income, fee conflicts, and position-level valuation patterns may inform future regulatory or legislative initiatives addressing governance standards for private credit fund managers. The outcome of this derivative action may establish precedent regarding the scope of fiduciary duties owed by BDC advisers to fund shareholders and the legal standards applicable to valuation governance and fee reasonableness in the private credit space.
