Accounting & Valuation
Portfolio valuation
Portfolio valuation
Your portfolio valuation determines LP returns, drives management fees, affects regulatory capital, and shapes how auditors view your fund. If you are managing an ABF portfolio or investing in one, you need to understand how marks get set, what governs the process, and where the judgment calls live.
The core challenge: most ABF positions do not have observable market prices. You are not marking a Treasury bond with real-time quotes. You are marking a residual interest in a warehouse facility backed by consumer loans, or a mezzanine tranche of a private CRE CLO, or a participation in an equipment lease pool. There is no Bloomberg screen that tells you what it is worth.
This page provides an overview of ABF valuation with a detailed worked example. For deeper dives on specific topics, see the linked pages below.
Why valuation matters
LP reporting and fund economics
Your NAV determines:
- Reported returns: An LP’s IRR and multiple depend on how you mark the portfolio at each reporting date
- Management fees: If you charge fees on NAV, your fee income varies with your marks
- Incentive fees: Carried interest crystallizes based on realized and unrealized gains
- Investor confidence: Consistent, defensible valuations build trust; volatile or aggressive marks erode it
A 5% difference in how you mark a $500M portfolio is $25M of reported value. That is not rounding error.
Regulatory capital
Bank and insurance investors in your fund (or in the underlying positions) need accurate valuations for:
- Risk-weighted assets (RWA): Banks calculate capital requirements based on position values
- NAIC designations: Insurance companies report holdings at fair value for statutory accounting
- CECL reserves: Credit loss provisions depend on carrying values
If your marks are aggressive, their capital calculations are wrong.
Audit and compliance
Auditors test your valuation methodology annually. They are looking for:
- Consistency in how you apply your policy
- Reasonableness of assumptions relative to market conditions
- Independence between the valuation function and the investment function
- Adequate documentation to support the marks
A qualified opinion or material weakness finding on valuation creates problems with LPs, regulators, and potential buyers.
Valuation framework overview
ABF valuation combines market data (when available) with modeling (when market data is scarce). The framework has four key components:
| Component | What It Covers |
|---|---|
| Fair value hierarchy | Level 1, 2, 3 classification; disclosure requirements; when Level 2 becomes Level 3 |
| Valuation methodologies | DCF approach, market comparables, dealer quotes, pricing services |
| Mark-to-model practices | When to model, hybrid approaches, documentation requirements |
| Valuation governance | Policy, independence, committee, third-party providers |
| NAV and liquidity | NAV calculation, side pockets, bid-ask spreads, liquidity adjustments |
Typical ABF fund composition: 10-20% Level 2, 80-90% Level 3. This is normal for the asset class. The key is having a rigorous process, not avoiding Level 3.
Worked example: valuing a consumer loan warehouse residual
You manage a credit fund that owns a residual interest in a $100M consumer loan warehouse facility. Here is how to value it.
Position details
- Warehouse facility size: $100M
- Advance rate: 85% (you are exposed to the first 15% of losses)
- Your residual investment: $15M at acquisition
- Current pool balance: $95M (some amortization)
- Weighted average coupon: 18%
- Weighted average remaining term: 24 months
- Current 30+ DQ: 4.5%
- Cumulative net loss to date: 2.8% (annualized CNL pace of ~7%)
Step 1: build the cash flow projection
Assumptions:
| Input | Value | Source |
|---|---|---|
| CPR | 25% | Historical prepayment on this pool |
| CDR | 8% | Current CNL pace plus buffer |
| Severity | 85% | Historical recovery rates |
| Facility rate | SOFR + 250 bps | Per credit agreement |
| Servicing fee | 1.0% | Per SSA |
Projected cash flows to residual (simplified, quarterly):
| Quarter | Pool Balance | Gross Yield | Losses | Facility Cost | Servicing | Residual CF |
|---|---|---|---|---|---|---|
| Q1 | $95.0M | $4.28M | $1.62M | $1.28M | $0.24M | $1.14M |
| Q2 | $85.8M | $3.86M | $1.46M | $1.15M | $0.21M | $1.04M |
| Q3 | $77.4M | $3.48M | $1.32M | $1.04M | $0.19M | $0.93M |
| Q4 | $69.9M | $3.14M | $1.19M | $0.94M | $0.17M | $0.84M |
| Q5-Q8 | … | … | … | … | … | $2.45M |
| Total | $6.40M |

Step 2: select discount rate
Comparable market data:
- Public consumer loan ABS BBB tranches: SOFR + 275 bps
- This is a first-loss residual, not a rated tranche
Adjustments:
| Factor | Adjustment |
|---|---|
| First-loss position (higher risk than BBB) | +400 bps |
| Private/illiquid (no secondary market) | +150 bps |
| Single-originator concentration | +50 bps |
| Total spread over SOFR | +875 bps |
With SOFR at 5.00%, discount rate = 13.75%
Step 3: calculate present value
Discounting the $6.40M of projected residual cash flows at 13.75% over a ~1.5 year WAL:
PV of residual cash flows: $5.65M
Step 4: run sensitivity analysis
| CDR | Disc Rate 12.0% | Disc Rate 13.75% | Disc Rate 15.5% |
|---|---|---|---|
| 6% | $6.85M | $6.60M | $6.35M |
| 8% | $5.90M | $5.65M | $5.45M |
| 10% | $4.95M | $4.75M | $4.55M |
| 12% | $4.00M | $3.85M | $3.70M |
This shows the mark could range from $3.70M to $6.85M depending on assumptions. Your base case is $5.65M.
Step 5: apply liquidity adjustment and finalize
Dealer color suggests a bid of $5.0M to $5.5M if you tried to sell. Given the model value of $5.65M and market color around $5.25M mid, you mark at $5.4M, reflecting:
- Model-derived value anchored to comparable spreads
- Liquidity discount for illiquid first-loss position
- Conservative positioning within the sensitivity range
Documentation:
- Mark: $5.4M (64% decline from $15M cost basis)
- Methodology: DCF with market-comparable discount rate
- Key assumptions: 8% CDR, 85% severity, 25% CPR, 13.75% discount rate
- Level 3 classification: Unobservable inputs (no market for residuals)
- Rationale: Performance has deteriorated from origination expectations; discount rate reflects current market spreads for subordinate consumer credit exposure plus illiquidity premium
Common valuation pitfalls
Stale marks
The problem: You are using last quarter’s mark when performance has deteriorated or market spreads have widened.
How to avoid it: Update marks at least quarterly. For positions with material changes (trigger breaches, performance deterioration, originator stress), update immediately.
Cherry-picking comparables
The problem: You select the most favorable comparable to justify your desired mark, ignoring comps that suggest lower value.
How to avoid it: Document all comparables considered, not just the one you used. Explain why you selected your primary comp and why others were less appropriate.
Ignoring structural differences
The problem: You benchmark to a public ABS tranche without adjusting for differences in enhancement, WAL, issuer quality, or liquidity.
How to avoid it: Build an adjustment framework and apply it consistently. A position with 5% enhancement is not comparable to one with 15% enhancement at the same spread.
Model overfitting
The problem: You calibrate your discount rate or assumptions to hit a predetermined mark rather than deriving the mark from reasonable inputs.
How to avoid it: Set assumptions before running the model. Document the sources for your inputs (comparable spreads, historical loss rates, prepayment data) independently of the output.
Insufficient documentation
The problem: Your audit file is thin. You have marks but no support for how you arrived at them.
How to avoid it: For every position, document: methodology, key inputs with sources, market data, adjustments, sensitivity analysis, and approval. If an auditor or LP asks “how did you get this number?”, you should have a complete answer in the file.
Important: “We used professional judgment” is not documentation. Your judgment should be traceable to specific inputs, comparables, and market data.
