Pool formation and onboarding

Pool formation is where your facility goes from signed documents to actual funding. This phase covers everything between closing and your first draw: assembling the collateral pool, verifying eligibility, setting up accounts, and executing your initial funding request. Get this right, and you’re funding loans within days of closing. Get it wrong, and you’re stuck in operational limbo while your origination pipeline backs up.

What you’re trying to accomplish

The goal is straightforward: take the loans you’ve originated, prove they meet the facility’s eligibility criteria, get them into the borrowing base, and draw capital against them.

The reality is messier. You’re coordinating across multiple parties (your operations team, legal counsel, account banks, custodians, the lender, calculation agents) while racing against your cash needs. Every day of delay costs you: you’re either sitting on unfunded originations or slowing down new production.

Typical timeline: 2-4 weeks from document execution to first draw. The variance depends on:

How prepared your data and documents are
Whether accounts are pre-staged or need to be opened
Custodian certification timelines
Lender’s first-draw audit requirements

Note: Start onboarding prep 3-4 weeks before anticipated closing. Account banks, custodians, and data feeds take longer than you expect.

The pool formation process

Here’s the sequence. Some steps run in parallel; others are gating.

Step 1: eligibility criteria review

Before you commit to funding any loans into the facility, map your portfolio against the eligibility criteria. Every facility has two levels of eligibility:

Loan-level criteria (each loan must independently qualify):

Credit score minimums (e.g., FICO > 640)
Maximum loan-to-value or advance rate
Loan age/seasoning requirements
Documentation status (all docs present, properly executed)
No delinquencies beyond threshold (e.g., current or <30 DPD)
No modifications, bankruptcies, or litigation
Originated within stated guidelines

Pool-level tests (the aggregate pool must qualify):

Weighted average credit score (e.g., WA FICO > 700)
Concentration limits by geography, obligor, loan size, product type
Weighted average coupon (WAC) minimums
Weighted average remaining term limits
Maximum single-obligor exposure

Run your proposed pool through these criteria before you submit anything. A spreadsheet cross-check takes an hour; discovering eligibility failures at draw request costs you days.

Step 2: data tape preparation

The data tape is the loan-level file that describes every asset in the pool. It’s your primary deliverable and the basis for the borrowing base calculation.

Standard fields include:

Loan identifier (unique ID you control)
Obligor information (name, address, credit score at origination)
Loan terms (principal balance, interest rate, payment amount, maturity date)
Collateral information (asset type, value, lien position)
Performance data (current status, delinquency, payment history)
Origination data (date, channel, underwriting exception flags)

What matters:

Match the data dictionary exactly. Your lender or calculation agent will provide a required format. Field names, data types, date formats, and allowed values are specified. Don’t deviate. A data tape that fails validation doesn’t get processed.
Fill every required field. Missing data on required fields makes loans ineligible. Common culprits: credit score (wasn’t pulled at origination), property value (appraisal pending), documentation status (not tracked in system).
Reconcile to source. Your tape should tie to your loan management system. Total UPB on the tape = total UPB in your LMS for the same loan population. If they don’t match, you have a data integrity problem that will surface later.

Common data quality issues:

Inconsistent date formats (MM/DD/YYYY vs. YYYY-MM-DD)
Text in numeric fields (commas in amounts, state names instead of codes)
Stale data (tape shows 30 DPD but loan paid current yesterday)
Truncation (loan ID cut off, addresses incomplete)
Duplicate records
Missing or null values coded inconsistently (blank vs. “N/A” vs. “0”)

Important: Run a test tape upload with your calculation agent before closing. Formatting errors that seem trivial will break automated processing and delay your draw.

Step 3: document custody setup

If your facility requires document custody (most do), you need to get loan documents into the hands of a custodian who will certify their presence and validity.

What goes into custody:

Original promissory note (or authoritative copy of eNote)
Security instrument (mortgage, deed of trust, UCC financing statement)
Endorsements (note endorsed in blank or to the SPV)
Assignments (security instrument assigned to SPV or trustee)
Allonges if applicable
Insurance certificates

Custodian options:

Third-party custodian (bank trust department, specialized custodian): Most common for rated deals and larger facilities. Examples: Wells Fargo Corporate Trust, U.S. Bank, Deutsche Bank.
Bailee arrangement: Lender holds documents directly or designates an affiliate. More common in smaller bilateral facilities.

Certification levels:

Document-present: Custodian confirms all required documents are present and appear properly executed
Document-deficient: One or more documents missing; loan may be eligible at a reduced advance rate or subject to cure period

Timeline: Custodian onboarding takes 2-3 weeks minimum. Document shipping, receipt, and initial certification adds another 1-2 weeks. Start this early.

Digital custody and eNotes: Increasingly common for consumer and some mortgage products. If your loans have eNotes, you need:

MERS registration (if applicable)
Authoritative copy on an approved eVault (DTCC, eOriginal, etc.)
Control agreements for electronic records
Custodian capable of handling electronic certification

Step 4: account setup

Your facility requires segregated accounts to manage cash flows. The exact accounts depend on the structure, but expect:

Account	Purpose
Collection account	Receives borrower payments
Distribution account	Holds funds pending waterfall distribution
Reserve account	Credit enhancement (if required)
Pre-funding account	Holds undeployed funds during ramp (if applicable)
Lockbox	Third-party controlled account for payment receipt

Account bank requirements:

Minimum credit rating (typically A-/A3 or higher)
Must be eligible under facility documents
Replacement required if downgraded below threshold

Account control agreements (ACAs): Every account needs an ACA signed by you, the account bank, and the secured party (lender or trustee). The ACA gives the secured party control over the account, a requirement for perfecting a security interest in deposit accounts.

ACA execution is a common bottleneck. Bank legal departments are slow. Get ACAs in process 3-4 weeks before you need the accounts operational.

Lockbox setup: If borrower payments route to a lockbox (common in consumer and commercial ABF), you need:

Lockbox agreement with the lockbox bank
Payment processing instructions
Remittance file format and delivery schedule
Testing before go-live

Common delays:

KYC/AML documentation requests (especially if your entity is new)
Signatory verification
ACA negotiation (minor markup requests that take weeks)
Internal bank approval queues

Note: Submit account applications 4 weeks before anticipated closing. Provide complete KYC documentation upfront. Follow up weekly.

Step 5: concentration limit verification

Concentration limits cap your exposure to any single risk dimension. Typical limits include:

Concentration Type	Typical Limit	Example
Single obligor	1-5% of pool	No borrower > 2% of UPB
Geographic	15-25% of pool	No state > 20% of UPB
Loan size	Max per loan	No loan > $500K
Credit score band	Band limits	<660 FICO capped at 10%
Product type	Product limits	Adjustable rate < 25%

How concentration limits work:

Loans exceeding a concentration limit typically aren’t excluded entirely. Instead, the excess balance gets a reduced advance rate (often 0%), effectively excluding it from the borrowing base.

Example:

Pool UPB: $50M
California concentration limit: 25% ($12.5M)
California loans in pool: $15M
Excess concentration: $2.5M
If base advance rate is 85%, the $12.5M within limit gets 85% advance; the $2.5M excess gets 0%
Net effect: $2.5M of collateral value “lost” to concentration haircut

Run your proposed pool through concentration limits before committing to funding. If you’re consistently bumping limits, discuss adjusting them with your lender or managing your origination pipeline to stay within bounds.

Step 6: initial borrowing base calculation

The borrowing base determines how much you can draw. Here’s the mechanics:

Borrowing Base = (Eligible Pool Balance × Advance Rate) - Concentration Haircuts - Required Reserves

Worked example:

Component	Amount	Notes
Total pool UPB	$50,000,000	All loans submitted
Less: Ineligible loans	($2,000,000)	Failed credit score, missing docs
Eligible pool balance	$48,000,000
Advance rate	85%
Gross availability	$40,800,000
Less: Concentration haircuts	($1,500,000)	Excess CA exposure at 0%
Less: Required reserves	($500,000)	Initial reserve funding
Net borrowing base	$38,800,000	Available to draw

Who calculates:

You prepare the initial calculation
Calculation agent or lender verifies
Officer’s certificate attests to accuracy

Supporting deliverables:

Data tape (loan-level file)
Borrowing base certificate (summary calculation with certification)
Eligibility exceptions schedule (if any loans require explanation)
Concentration limit compliance summary

Step 7: first draw request

You’re ready to fund. Here’s the process:

Notice requirements:

Most facilities require 2-3 business days’ notice for draws
Notice must include: draw amount, funding date, wire instructions, certifications
Some facilities allow same-day or next-day draws for smaller amounts

Conditions precedent to first draw:

The lender won’t fund until these are satisfied:

CP Category	Items
Legal	All transaction documents executed and delivered
Accounts	All accounts open; ACAs executed
Custody	Initial pool documents delivered and certified
Opinions	True sale opinion, UCC opinion, corporate opinions delivered
Insurance	Required insurance policies in place
Data	Initial data tape delivered and validated
Borrowing base	Initial borrowing base certificate delivered
No default	Bring-down certificate confirming no default or MAE
Funding	Any required initial equity contribution funded

First draw checklist:

Before submitting your draw request, confirm:

Minimum draws: Most facilities have minimum draw amounts ($1M-$5M) to avoid administrative burden. Plan your initial pool size accordingly.

Funding mechanics:

You submit draw request with required notice
Lender verifies conditions precedent satisfied
Lender wires funds to distribution account
Funds flow to originator per agreed funding mechanics
Post-funding: Lender may conduct audit of initial pool within 30-60 days

Common onboarding issues and how to avoid them

Issue	Cause	Prevention
Account opening delays	KYC documentation incomplete, bank backlog	Submit applications 4 weeks early; provide complete docs upfront
ACA execution delays	Bank legal review, minor markup disputes	Start ACA process at signing; escalate if no movement after 10 days
Custody certification gaps	Missing documents discovered at delivery	Pre-audit loan files before shipping; don’t assume files are complete
Data tape rejection	Formatting errors, validation failures	Test upload with calc agent before closing
Eligibility surprises	Loans fail criteria not anticipated	Run full eligibility screen on proposed pool before committing
UCC filing delays	Slow filing offices, rejections	File immediately at signing; use expedited filing services
Missing opinions	Counsel delays, late review comments	Track opinions separately; daily follow-up in final week
Systems integration failures	Data feeds misconfigured	Test all feeds to trustees/agents before go-live

Onboarding timeline template

Phase	Timing	Activities
Pre-closing	T-4 to T-3 weeks	Account applications, custodian engagement, KYC submission
	T-3 to T-2 weeks	Data tape preparation, eligibility pre-screen, document collection
	T-2 to T-1 weeks	Test tape upload, ACA drafts circulating, custody shipping begins
Closing	T-0	Document execution, UCC filing, opinion delivery
Post-closing	T+1 to T+5 days	Account confirmation, wire testing, custody receipt confirmation
	T+5 to T+10 days	Custody certification, borrowing base calculation
First draw	T+10 to T+14 days	Draw request, CP verification, funding

Special considerations by asset class

Consumer loans

State licensing verification: Confirm you hold required licenses in all origination states; licensing gaps can make loans ineligible or voidable
TILA/RESPA compliance: Lenders may require third-party compliance review of a sample
Credit reporting: Ensure credit bureau reporting is accurate and current
SCRA compliance: For military borrowers, verify SCRA protections are properly handled

Mortgage loans

Title policies: Each loan needs a lender’s title policy; gap in chain = ineligible
Assignment chain: Mortgage must be properly assigned through each transfer; MERS registration simplifies this
State-specific requirements: Recording requirements, power of attorney rules, and foreclosure procedures vary by state
Agency eligibility: If loans are agency-eligible, maintain eligibility throughout facility life

Equipment finance

UCC-1 filings: File in debtor’s state of organization and state where collateral is located (if fixtures)
Equipment schedules: Detailed descriptions tied to serial numbers or VINs
Appraisals: Lenders may require orderly liquidation value (OLV) appraisals for larger equipment
Insurance: Verify equipment is insured with loss payee endorsement

Trade receivables

Obligor notification: Some facilities require notification to underlying obligors; others permit “non-notification” structures
Anchor concentration: Large obligor concentrations are common; watch concentration limits carefully
Dilution: Non-credit adjustments (returns, disputes, credits) reduce borrowing base; track dilution rates
Verification: Lenders may require verification of a sample of invoices directly with obligors

Auto loans and leases

Title status: Lienholder must be perfected on title; electronic lien systems vary by state
DMV processing: Title perfection can take 2-4 weeks depending on state
Lease residuals: For leases, residual value assumptions must be documented and defensible
Subvention: Manufacturer-subsidized rates may have clawback provisions affecting collateral value

Key takeaways

Start early: Begin onboarding prep 3-4 weeks before closing. Account opening and custody setup have long lead times.
Test everything: Run test tapes, test wire flows, test data feeds. Discovering integration failures at first draw is expensive.
Pre-screen eligibility: Don’t assume your loans will qualify. Run your proposed pool through eligibility criteria before committing.
Track deliverables obsessively: Create a closing checklist with responsible parties and deadlines. Follow up daily in the final week.
Build cushion into your timeline: If you need to draw by a certain date, work backwards and add buffer. Everything takes longer than expected.
Communicate proactively: If you hit a delay, tell your lender early. Surprises at funding are worse than early warnings.

Your first draw sets the tone for the facility relationship. A clean, well-organized onboarding signals operational competence. A messy one signals risk.
