Other counterparties

Your legal counsel, trustee, servicer, calculation agent, and rating agency get most of the attention when you’re building out a facility. But five other counterparty categories can quietly derail your deal if you engage them too late or select poorly: accountants and auditors, document custodians, hedging counterparties, insurance providers, and verification agents.

This topic covers what each does, when you need them, how to select them, and what they cost. None of these are as complex as structuring your waterfall or negotiating covenants, but each can add weeks to your timeline if mishandled.

Accountants and auditors

What they do in ABF

Accountants serve several distinct functions in ABF transactions:

Agreed-upon procedures (AUPs). Your lender or investors want independent verification that certain assertions are true. An AUP engagement tests specific items you define, for example, that 100 sampled loan files contain all required documents, that FICO scores in the tape match source documentation, or that loans meet your stated underwriting guidelines. The accountant doesn’t opine on the overall portfolio; they test what you ask them to test and report findings.

Comfort letters. For rated deals or public offerings, accountants provide “negative assurance” on data in offering documents. The comfort letter essentially says: “We reviewed the statistical data in sections X, Y, and Z and found nothing inconsistent with company records.” This isn’t an audit opinion, but it provides legal protection for underwriters and issuers.

Servicer audits. Your facility agreement likely requires annual audits of servicing operations. The two main standards are:

SOC 1 (SSAE 18): Controls-focused audit testing whether servicing controls operate effectively
USAP (Uniform Single Attestation Program): MBA-sponsored standard for mortgage servicers; covers compliance, operations, and controls

Originator financial audits. Most warehouse lenders require audited financial statements, typically covering the past 2-3 fiscal years. If your company is young, you may need to fast-track getting audited.

When you need each service

Service	When Required	Who Requires It
AUPs on loan files	At closing; sometimes periodic	Lender due diligence, rating agencies
Comfort letters	Closing for rated/public deals	Underwriters, rating agencies
SOC 1/USAP servicer audit	Annually	Facility covenant, investors
Originator financial audit	Initial facility qualification	Warehouse lenders
SPV audits	Annually if consolidated	Accounting requirements

For a first warehouse facility, you likely need originator financial audits (historical), possibly an AUP on a loan file sample, and confirmation that your servicer has a current SOC 1 or USAP. For a rated term deal, add comfort letters and expect more extensive AUP requirements.

Selection criteria

ABS/ABF experience matters. The Big Four (Deloitte, EY, KPMG, PwC) all have structured finance practices with deep ABF experience. Their teams know what investors and rating agencies expect. But they’re expensive. Regional firms with active structured finance practices (RSM, BDO, Grant Thornton, Crowe) can handle most ABF work at lower cost.

Asset class familiarity. AUPs for mortgage files differ from AUPs for equipment leases or consumer loans. Make sure your accountant has tested similar collateral types. Ask for relevant engagement references.

Turnaround time. If you’re on a closing timeline, your accountant’s capacity matters. Large engagements (comfort letters for big deals, extensive AUPs) may need 4-6 weeks. Confirm availability before you assume they can deliver.

Lender preferences. Some lenders have preferred accountant lists or won’t accept work from firms below a certain size. Check requirements before engaging.

Fee ranges

AUPs: $15K-75K depending on scope. A simple 50-file documentation check runs $15K-25K. A comprehensive 200-file review testing credit, compliance, and documentation can exceed $75K.

Comfort letters: $25K-100K+ depending on deal size and disclosure complexity. More data tables in your offering document means more work for the accountant.

Servicer audits: $40K-150K annually. Smaller servicers with straightforward operations are at the low end. Large servicers with multiple asset classes, offshore operations, or complex systems pay more.

How fees are paid: Direct engagement between you and the accountant, not through the waterfall. You pay for AUPs and comfort letters. The servicer pays for servicer audits (though that cost ultimately flows through servicing fees).

Document custodians

What they do

Document custodians hold your original loan documents in secure vaults and track their status. This sounds simple, but it’s operationally critical. Your lender’s security interest in many asset classes depends on possession of original documents.

Physical custody. The custodian receives, processes, and stores original notes, security agreements, titles (for auto), mortgages, and other collateral documents. For mortgages, this includes the original note with proper endorsement chain and recorded mortgage assignments.

Bailee letters. The custodian acknowledges holding documents as bailee (custodian on behalf of another party). Your lender receives a bailee letter confirming the custodian holds collateral documents on the lender’s behalf. This is how your lender perfects a possessory security interest.

Document tracking. Custodians maintain detailed records of what they’ve received, what’s missing, and what has exceptions. You can typically access a portal showing exception status by loan.

Release management. When you need documents back (borrower payoff, modification, foreclosure, servicing transfer), the custodian releases them per your lender’s instructions. Release protocols prevent unauthorized document removal.

When you need a custodian

Warehouse facilities: Most warehouse lenders require an independent custodian, particularly for mortgages and auto loans. The lender won’t hold physical documents themselves, and they won’t trust you to self-custody collateral.

Term securitization: The trustee typically holds collateral directly or engages a custodian. For mortgages, the trustee or a document custodian maintains the mortgage files.

Asset class differences: Hard-copy custody requirements vary:

Mortgages: Almost always require physical custody of original note with proper endorsement
Auto loans: Require custody of titles in title-holding states; electronic lien holder notation in ELT states
Consumer loans: Often electronic-only; physical custody less common
Equipment: May require original lease agreements or just UCC filings depending on collateral type

If your assets are consumer loans with electronic documentation only, you may not need a traditional document custodian, though you’ll still need systems to demonstrate possession and control for UCC purposes.

Selection criteria

Vault security and disaster recovery. Your documents are irreplaceable. Custodians should have climate-controlled vaults, fire suppression, access controls, redundant facilities, and business continuity plans. Ask about their DR protocols.

Asset class experience. Mortgage custodians understand endorsement chains, allonges, lost note affidavits, and recording requirements. Auto custodians understand title processing across 50 states. Consumer loan custodians understand electronic records. Don’t hire a mortgage custodian to handle your auto titles.

Exception tracking systems. You’ll have document exceptions. Your purchase and sale agreement gives you cure periods to deliver missing documents. You need visibility into exception status to avoid covenant issues. Good custodians provide real-time dashboards.

Turnaround times. How quickly can they certify new files? Process releases? Handle volume spikes? If you’re a high-volume originator, capacity matters.

Integration with your systems. Some custodians offer API connections to loan origination systems for automated tracking. This reduces reconciliation headaches as you scale.

Fee ranges

Initial certification: $5-25 per file. More complex document sets (full mortgage files with multiple recorded documents) cost more than simpler files.

Ongoing custody: $1-5 per file per year. Volume discounts apply for larger portfolios.

Exception tracking: Often included in base fees. Some custodians charge per exception or per cure processed.

Release fees: $15-50 per release, depending on complexity and whether documents need to be copied or re-delivered.

How fees are paid: Setup and initial certification often paid directly at closing. Ongoing custody fees typically paid through the waterfall as a transaction expense, ahead of most other distributions.

Major providers

Bank custodians:

US Bank: Largest ABS document custodian; handles mortgages, auto, consumer, equipment
Deutsche Bank: Strong in structured products
Wells Fargo: Active in mortgage custody
Computershare: Broad coverage across asset classes

Specialty custodians:

Nationwide Title Clearing: Mortgage document processing and custody
SitusAMC: Mortgage-focused custodial services
ClosingCorp: Settlement and custody services

Bundled trustee/custodian: Most major trustees (US Bank, Wilmington, Deutsche Bank Trust) offer custody services bundled with trustee engagements. This can simplify counterparty management but may not always be the most competitive option.

Hedging counterparties

What they do

Hedging counterparties provide interest rate derivatives that manage the mismatch between your asset yields and liability costs.

Interest rate swaps. You pay fixed and receive floating (or vice versa) on a notional amount tied to your deal. If your assets are fixed-rate consumer loans and your warehouse pays SOFR + spread, a pay-fixed/receive-SOFR swap converts your floating liability to fixed, matching your asset cash flows.

Interest rate caps. You pay an upfront premium for protection against rates rising above a strike level. If SOFR exceeds the strike, the cap pays you the difference on the notional amount. Caps provide asymmetric protection: your downside is limited to the premium paid, but you benefit if rates stay low.

Basis swaps. Your assets might pay Prime while your liabilities pay SOFR. A basis swap exchanges Prime for SOFR (or vice versa) to eliminate basis mismatch.

When you need hedging

The decision framework is straightforward:

Your Assets	Your Liabilities	Mismatch?	Hedge Needed?
Fixed rate	Fixed rate	No	No
Floating	Floating (same index)	No	Usually no
Fixed	Floating	Yes	Yes, swap or cap
Floating	Fixed	Yes	Yes, swap
Floating (Prime)	Floating (SOFR)	Basis only	Sometimes

Structural requirements. Many warehouse facilities require interest rate caps regardless of your mismatch analysis. Lenders want protection against rate scenarios where your assets don’t cover debt service. If your term sheet specifies hedging, you don’t have a choice.

Cost-benefit analysis. Hedges cost money. A cap premium on a $50M notional for 2 years might run $100K-300K depending on the strike and rate environment. You need to weigh that against the risk of unhedged exposure. For most originators with meaningful fixed/floating mismatch, hedging is worth the cost.

ISDA documentation

You can’t execute swaps or caps without an ISDA (International Swaps and Derivatives Association) agreement. The documentation includes:

Master agreement. The standard ISDA 2002 Master Agreement governs all trades between you and the counterparty. This document rarely changes, but the Schedule contains your negotiated terms.

Schedule. The Schedule modifies the Master Agreement for your specific situation: governing law, calculation agent, events of default, termination events, netting provisions, and other elections. This is where negotiation happens.

Credit support annex (CSA). The CSA governs collateral posting. If you’re a small originator dealing with a bank, expect a one-way CSA where you post collateral if the trade moves against you but the bank doesn’t post if it moves against them. Larger counterparties negotiate two-way CSAs.

Trade confirmations. Each specific trade (your cap, your swap) has a confirmation document with the terms: notional, tenor, rate, strike, payment dates.

Timeline warning: If you don’t have an existing ISDA relationship with your hedge counterparty, budget 4-8 weeks to negotiate. This can easily delay your closing if you wait too long.

Selection criteria

Counterparty rating requirements. Your facility documents likely specify minimum ratings for hedge counterparties, typically A-/A3 or better from S&P/Moody’s. If your counterparty gets downgraded below the threshold, structural consequences kick in (collateral posting, replacement, termination).

Downgrade provisions. Understand what happens if your hedge counterparty is downgraded. Well-drafted structures require the counterparty to post collateral, find a replacement, or face termination. Review these provisions carefully.

Pricing competitiveness. Get quotes from 3-5 dealers. Swap and cap markets are competitive, and bid-offer spreads vary. A few basis points on a $100M notional adds up.

Existing relationships. If you already have an ISDA in place with a dealer, it’s faster to execute additional trades under that agreement than to onboard a new counterparty.

Fee ranges

Swap execution. There’s no explicit fee; economics are embedded in the bid-offer spread. Typically 2-10 basis points of notional, meaning a $50M swap might have $10K-50K embedded in the execution rate versus mid-market.

Cap premiums. Highly variable based on:

Notional amount
Tenor (2 years vs. 5 years)
Strike level (at-the-money vs. out-of-the-money)
Current rate volatility

Budget $50K-500K+ for typical ABF hedges. In high-volatility environments, cap premiums can spike significantly.

ISDA negotiation costs. If you’re establishing a new ISDA relationship, expect $15K-40K in legal fees. For subsequent trades under an existing ISDA, legal costs are minimal.

How payments work: Cap premiums are typically paid upfront (or occasionally amortized into your deal). Swap payments net settle periodically (monthly or quarterly), with the in-the-money party receiving the net payment.

Major providers

Major bank dealers:

JPMorgan, Bank of America, Citi, Goldman Sachs, Morgan Stanley: Full-service derivatives desks, competitive on large hedges
Wells Fargo, Barclays: Active in structured products hedging

Regional banks:

US Bank, PNC, Truist, Fifth Third: Often more competitive on smaller hedges ($10M-50M notional); relationship-focused

Interdealer brokers. Firms like Tullett Prebon, ICAP, and BGC Partners can help you source competitive pricing by running an auction among dealers.

Note: If you’re doing a $25M hedge, you may get better execution from a regional bank that values the relationship than from a bulge bracket desk where you’re a small ticket.

Insurance providers

What they provide in ABF

Insurance providers cover various risks across your ABF operations:

Fidelity bonds. Protect against employee dishonesty, theft, fraud, and forgery. If an employee embezzles borrower payments or forges documents, your fidelity bond responds.

Errors and omissions (E&O). Covers claims arising from professional mistakes in origination or servicing. If you miscalculate a borrower’s payment or fail to apply a payment correctly and the borrower sues, E&O coverage applies.

Directors and officers (D&O). Protects your management team from claims related to their decisions running the company. Relevant if investors or creditors allege mismanagement.

Rep and warranty insurance. Covers your repurchase exposure when loans breach representations. If your purchase agreement requires you to repurchase loans with compliance defects, rep and warranty insurance pays those claims up to policy limits.

Force-placed insurance. For secured assets (homes, equipment, vehicles), borrowers must maintain insurance. When they lapse coverage, you force-place insurance and charge the borrower. You need a force-placed insurance program in place to do this.

Credit enhancement insurance (less common now). Historically, financial guaranty insurance (monoline wraps) enhanced credit on ABS tranches. After 2008, this market largely disappeared, though Assured Guaranty remains active in certain sectors.

When required

Your facility agreement specifies insurance requirements. Typical provisions:

Coverage Type	Typical Minimum	Who’s Protected
Fidelity bond	$5M-25M	Lender, investors
E&O	$5M-25M	Lender, investors, borrowers
D&O	$2M-10M	Management, directors
Force-placed program	Must be in place	Borrowers, collateral value

Fidelity, E&O, D&O: Standard requirements in most warehouse facilities and term deals. Coverage levels scale with deal size and originator risk profile.

Rep and warranty insurance: Optional but increasingly common. Useful if you want to cap your exposure to repurchase claims. Particularly relevant for mortgage originators selling to aggregators or securitizing with extensive rep packages.

Force-placed insurance: Required if you’re financing secured assets where borrower-maintained insurance is expected. You need a carrier relationship and administrative process to track coverage lapses and place coverage.

Selection criteria

Coverage adequacy. Your facility specifies minimum limits. Make sure your coverage meets or exceeds those requirements. If the facility requires $15M fidelity and you have $10M, you can’t close.

Carrier rating. Facilities often require minimum ratings (A.M. Best A- or better is common). Check that your carrier qualifies.

Claims experience. Ask carriers and brokers about claims experience in your industry. How have similar claims been handled? What’s the typical resolution time?

Policy exclusions. Read the exclusions carefully. E&O policies in particular can have carve-outs that limit coverage for the exact scenarios you’re worried about.

Renewal reliability. Some specialty markets have limited carrier capacity. If your asset class or company profile is unusual, confirm that coverage will be renewable.

Fee ranges

Fidelity bonds: $5K-25K annually for typical originator/servicer size. Higher limits and higher-risk profiles cost more.

E&O coverage: $10K-50K annually. Premiums depend on limits, deductibles, prior claims history, and the nature of your operations.

D&O: $15K-75K annually. Larger companies and those with litigation history pay more.

Rep and warranty insurance: 0.5%-2.0% of covered exposure, typically structured as a 3-5 year policy. A $100M mortgage pool with rep and warranty insurance might cost $500K-2M in premium.

How paid: Direct premiums paid to carriers or through brokers. These costs don’t flow through the waterfall; they’re operating expenses. Force-placed premiums are typically passed through to borrowers.

Major providers

Fidelity, E&O, D&O:

Chubb, AIG, Travelers, Hartford, Zurich: Major carriers with financial institution practices
Various Lloyd’s syndicates: Active in specialty coverage

Rep and warranty insurance:

Arch Capital, Assured Guaranty: Active in transaction-based policies
Various Lloyd’s syndicates: Significant market share
Specialized MGAs: Ethos (focused on mortgage rep and warranty)

Force-placed insurance:

American Modern, QBE, Assurant: Dominant in force-placed residential
Specialty carriers for equipment and other asset types

Brokers: Marsh, Aon, Willis Towers Watson, and regional brokers help place coverage competitively and navigate policy terms. For specialty coverage (rep and warranty, force-placed), working with a broker experienced in that market is valuable.

Verification agents

What they do

Verification agents provide independent third-party due diligence (TPR) on your loan files. They review a sample of files and test whether origination quality matches your representations.

Loan file review. Verification agents review individual loan files against your underwriting guidelines, checking credit calculations, documentation completeness, and compliance with stated policies.

Compliance testing. For consumer loans, this includes state licensing verification, usury testing, and regulatory compliance (TILA, RESPA, ATR/QM for mortgages, state-specific requirements).

Data integrity verification. Agents compare tape data to source documents. Is the stated FICO score correct? Does the income documentation support the stated income? Do loan amounts and terms match the note?

Re-underwriting. For credit-focused diligence, agents recalculate key metrics: DTI ratios, LTV calculations, credit scores. This confirms your underwriting was applied correctly.

When used

Term securitization. TPR is standard practice. Rating agencies expect independent file review, and investors rely on TPR findings to assess origination quality. Sample sizes typically range from 10-25% adverse selection (higher-risk loans) plus 5-10% random selection.

Warehouse facilities. Some lenders require periodic TPR, often annually or at upsizing. File samples are usually smaller than for rated deals.

Forward flow arrangements. Buyers often require TPR on a sample before the first purchase to validate origination quality.

Cross-reference: Verification agents perform point-in-time file review, while calculation agents (Calculation Agents and Data Agents) handle ongoing data reporting and periodic compliance testing. For facilities with extensive ongoing file review requirements, the calculation agent may manage the process.

Scope of work

A typical TPR engagement includes:

Sample selection. Adverse selection targets higher-risk loans (high DTI, low FICO, high LTV, recent origination). Random selection provides a cross-section of the pool. Total sample sizes for rated deals often run 15-30% of the pool.

Review categories:

Credit re-underwrite: Income/employment verification, DTI calculation, credit review
Compliance: Regulatory disclosure timing, fee tolerance, licensing
Documentation: Required documents present and properly executed
Property (if applicable): Appraisal review, title, insurance

Grading. Files receive grades, typically A/B/C or 1/2/3:

A/1: Materially compliant, no issues
B/2: Minor exceptions, not material
C/3: Material exceptions requiring attention (potential repurchase, documentation deficiency)

Final report. The verification agent delivers a report summarizing findings, exception detail by loan, and overall assessment. This report goes to rating agencies, investors, and lenders.

Selection criteria

Asset class specialization. Mortgage TPR requires different expertise than consumer loan or equipment lease review. Make sure your verification agent has relevant experience.

Rating agency acceptance. Some agencies maintain preferred vendor lists or have established relationships with certain TPR firms. Confirm your choice is acceptable to your rating agencies.

Turnaround time. TPR can take 2-4 weeks depending on sample size and complexity. If you’re on a tight closing timeline, confirm the agent can deliver.

Bandwidth. For large pools, make sure the agent has capacity. A 500-file review requires significant staffing. Ask about their current workload and ability to ramp.

Fee ranges

Per-file review: $75-300 per file depending on:

Asset class (mortgages are more complex than consumer unsecured)
Review depth (full re-underwrite vs. documentation check)
File condition (clean files review faster than messy files)

Typical deal cost: For a rated term securitization:

$50K-100K for a consumer loan deal with 500-loan sample at $100-200/file
$150K-300K+ for a mortgage deal with extensive sample and full compliance review

Rush fees: 25-50% premium for expedited turnaround. If you need results in 10 days instead of 3 weeks, expect to pay for prioritization.

How paid: TPR costs are typically paid directly by the issuer, often from closing proceeds. Not a waterfall expense.

Coordination and timing

Counterparty engagement timeline

Stage	Action
Term sheet / LOI	Identify which counterparties you’ll need; no engagement yet
Post-commitment / diligence	Engage accountants for AUPs; begin custodian onboarding; start ISDA negotiation if new
6 weeks pre-close	Confirm insurance coverage; finalize hedge terms; schedule comfort letter delivery
2-4 weeks pre-close	TPR underway (for rated); document custody certification in progress
Closing	Bailee letters executed; hedges closed; AUPs and comfort letters delivered

Common mistakes

Engaging too late. ISDA negotiation can take 6-8 weeks if you don’t have an existing relationship. Custodian onboarding requires vault setup, system configuration, and staff training on your file requirements. TPR firms book up during active market periods. Give yourself lead time.

Underestimating custody setup. First-time custodian relationships require more setup than you expect. The custodian needs your document checklists, exception protocols, release authorities, and system access. Budget 4-6 weeks minimum.

Insufficient coverage limits. Your term sheet requires $15M fidelity bond; you have $10M coverage; your broker says it takes 2-3 weeks to bind additional coverage. Now your closing is delayed. Confirm insurance requirements early and make sure you can meet them.

Ignoring counterparty rating requirements. Your hedge counterparty gets downgraded and no longer meets facility requirements. You need to find a replacement counterparty, negotiate new ISDA terms, and potentially unwind and re-execute your hedge. This is expensive and time-consuming. Monitor counterparty ratings and have contingency plans.

Cost summary

Counterparty	Typical Cost Range	Payment Method
Accountant (AUPs)	$15K-75K per engagement	Direct
Accountant (comfort letter)	$25K-100K	Direct
Servicer audit (SOC 1/USAP)	$40K-150K annually	Servicer pays
Document custodian (initial)	$5-25 per file	Direct or closing proceeds
Document custodian (ongoing)	$1-5 per file annually	Waterfall
Hedge counterparty (cap premium)	$50K-500K+	Upfront or waterfall
Hedge counterparty (swap)	Embedded in spread	Net settlement
Fidelity/E&O insurance	$15K-75K annually	Direct
D&O insurance	$15K-75K annually	Direct
Rep and warranty insurance	0.5-2.0% of exposure	Direct
Verification agent (TPR)	$50K-300K+ per engagement	Direct or closing proceeds

Illustrative pricing. See pricing disclaimer.

For a typical first warehouse facility, budget $50K-150K for these counterparties collectively (excluding ongoing costs). For a rated term securitization, budget $150K-400K+ depending on deal size and complexity.

Key takeaways

These counterparties may seem secondary to your lender, trustee, and servicer, but they can delay or derail your closing if mismanaged:

Identify requirements early. At term sheet stage, know which counterparties your deal requires. Don’t wait for closing to discover you need an ISDA or TPR.
Allow adequate lead time. ISDA negotiation, custodian onboarding, and TPR all take longer than you expect. Build buffer into your timeline.
Budget realistically. These costs add up. Include them in your all-in cost of capital analysis. A $100M term deal might have $200K-400K in accountant, TPR, hedge, and insurance costs before you count legal, trustee, and rating agency fees.
Monitor counterparty health. Your hedge counterparty’s credit rating matters. Your custodian’s operational stability matters. Don’t set and forget.
Build relationships before you need them. If you know you’ll eventually do a rated deal, start the ISDA negotiation process during your warehouse phase. Get your auditor relationship established early. Relationships built under time pressure cost more.
