lev-os Managing Securitization Warehouse Facilities
When To Use
- Structuring or renewing a warehouse credit facility to fund asset origination ahead of term securitization
- Evaluating advance rates, borrowing base mechanics, and concentration limits for a new or existing warehouse line
- Modeling ramp-up timelines and warehouse economics (carry cost vs. term takeout spread)
- Monitoring eligibility criteria compliance and mark-to-market triggers during the accumulation period
- Coordinating across originator, warehouse lender, trustee/custodian, and rating agencies during facility lifecycle
Inputs To Gather
- Facility term sheet or credit agreement — committed amount, maturity, extension options, pricing grid (spread over SOFR/benchmark + fees)
- Collateral parameters — asset class (consumer ABS, RMBS, CLO, auto, etc.), eligible asset definitions, concentration limits, seasoning requirements, geographic or obligor caps
- Advance rate schedule — initial advance rates by collateral type, haircuts for non-performing or aged assets, mark-to-market methodology
- Borrowing base certificate (most recent) — current outstanding, eligible collateral balance, excess availability, compliance with sub-limits
- Ramp-up plan — target origination volume, expected time to fill the warehouse, pipeline data from originator
- Term takeout assumptions — expected securitization frequency, minimum deal size, target timing from warehouse close to term issuance
- Fee structure — commitment fees (drawn/undrawn), upfront fees, utilization fees, early termination penalties
- Trigger/covenant package — portfolio performance triggers (delinquency, default, loss), borrowing base deficiency cure periods, market value decline triggers [VERIFY specific trigger levels against credit agreement]
Workflow
Map the facility structure
- Identify the warehouse lender(s), SPV borrower, servicer, backup servicer, custodian, and any credit enhancer
- Confirm whether the facility is a repurchase (repo) structure or a traditional revolving credit facility — this drives accounting treatment and margin call mechanics
- Document the waterfall: interest and principal payment priorities, reserve account requirements, and excess spread disposition
Analyze advance rates and borrowing base
- Build a matrix of advance rates by collateral sub-type (e.g., prime auto 85%, subprime auto 75%, non-performing 0%)
- Calculate effective blended advance rate against the current or projected portfolio composition
- Stress-test the borrowing base under adverse scenarios: rating migration, prepayment spikes, increased delinquencies reducing the eligible pool
- Flag any assets that are approaching ineligibility (seasoning limits, performance triggers) and quantify the borrowing base impact of their exclusion
Model warehouse economics
- Calculate all-in carry cost: benchmark rate + warehouse spread + commitment fees + hedging cost (if floating-rate collateral is warehoused against a fixed-rate takeout)
- Compare carry cost against projected term securitization execution (weighted-average coupon on issued notes) to determine negative carry during ramp
- Estimate total warehouse cost per securitization cycle: (average outstanding × all-in rate × ramp period in days / 360) + fixed fees
- Assess break-even utilization — the minimum portfolio balance at which fee income or spread covers undrawn commitment fees
Monitor eligibility and compliance
- Track concentration limits in real time: single obligor, geographic, industry, FICO/credit band, loan-to-value, or weighted-average life constraints
- Confirm each new asset added to the warehouse satisfies eligibility representations before funding
- Monitor portfolio performance triggers monthly: delinquency ratios (30/60/90+ days), cumulative default rate, cumulative net loss rate against threshold levels [VERIFY trigger definitions — some facilities use static pool metrics vs. dynamic pool]
- Prepare borrowing base certificates per the required delivery schedule (typically monthly or with each funding request)
Coordinate ramp-up and term takeout
- Maintain a ramp-up tracker: target fill date, current funded balance as a percentage of target deal size, pipeline-to-close conversion rates
- Identify the optimal takeout window — balance between minimizing warehouse carry and achieving sufficient deal size for efficient term execution
- Coordinate with rating agencies on preliminary feedback as the portfolio nears critical mass
- Prepare the collateral tape and stratification tables needed for the term securitization offering documents
Report facility status
- Produce a warehouse dashboard summarizing: outstanding balance, available capacity, days in warehouse (weighted average), portfolio composition snapshot, trigger headroom (distance to breach for each performance metric)
- Highlight upcoming maturities, extension decision deadlines, and any required lender approvals
- Escalate borrowing base deficiencies, trigger breaches, or collateral disputes immediately with recommended cure actions
Output
- Warehouse Facility Summary — one-page overview of structure, counterparties, key terms, and current utilization
- Borrowing Base Analysis — detailed eligible collateral breakdown, advance rate application, excess availability calculation, and stress scenarios
- Warehouse Economics Model — carry cost analysis, break-even utilization, and comparison to term takeout economics across multiple ramp timelines
- Compliance Monitoring Report — concentration limit utilization, performance trigger headroom, eligibility exception log
- Ramp-Up Tracker — origination pipeline status, projected fill date, and recommended term takeout timing
Quality Checks
- Advance rates applied match the executed credit agreement schedule — not indicative term sheet rates [VERIFY against final signed facility documents]
- Borrowing base arithmetic ties to the custodian's collateral report and servicer's tape
- All-in carry cost includes every fee component (commitment, utilization, admin, trustee) — not just the margin spread
- Concentration limits are tested against the full portfolio, not just the most recent additions
- Performance trigger calculations use the correct denominator and lookback period as defined in the facility agreement [VERIFY — some use trailing 3-month annualized, others use cumulative since closing]
- Mark-to-market valuations, if applicable, use the methodology specified in the agreement (dealer quotes, model-based, index-referenced)
- Ramp-up projections are reconciled against actual origination run-rates, not aspirational targets
