SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Structured credit analysis requires connecting legal structure, collateral behavior, waterfall mechanics, and tranche-level risk, and analysts often anchor on spread before understanding whether the structure actually protects them. This Skill provides a disciplined underwriting workflow for securitized products so tranche recommendations rest on structure and collateral quality rather than headline yield. ## Core Features & Use Cases - Structure-first underwriting: Maps true sale, bankruptcy remoteness, tranche attachment and detachment, reserve accounts, and OC/IC test mechanics before relative value. - Collateral and agent assessment: Evaluates default timing, loss severity, prepayment behavior, concentration risk, and the quality of CLO managers, servicers, and special servicers. - Scenario and monitoring outputs: Produces structure snapshots, waterfall and test dashboards, base/downside/severe scenarios, and tranche-level recommendations with monitoring breakpoints. - Use Case: An analyst reviewing a new-issue CLO can produce a full underwriting package covering collateral metrics, coverage test cushions, manager evaluation, and scenario analysis showing which tranche protections fail first. ## Quick Start Analyze this CLO new-issue deal and produce a structure snapshot, waterfall and test dashboard, scenario analysis, and tranche recommendation with monitoring items.

Frequently Asked Questions about Securitization and CLOs

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I analyze a CLO before investing in a tranche?▼

Start with the legal structure and waterfall, then underwrite collateral behavior including default timing, loss severity, and concentration. Evaluate the CLO manager separately from vintage effects, stress the structure across scenarios, and only then compare spread to peers.

What is the difference between OC and IC tests in a CLO?▼

Overcollateralization tests compare collateral par value to outstanding tranche balances, while interest coverage tests compare collateral interest income to tranche interest due. Failing either test redirects cash flows to senior tranches, trapping cash away from junior holders.

How does CMBS analysis differ from direct CRE underwriting?▼

CMBS analysis adds tranche structure, balloon refinance risk, and special servicing dynamics on top of property-level fundamentals like DSCR, LTV, and lease rollover. Property-level underwriting should use a dedicated CRE analysis skill, while this skill covers securitization-specific mechanics.

When should I use OAS instead of nominal spread for MBS?▼

Use OAS when embedded prepayment optionality materially changes realized cash flows, as in agency RMBS and other optionality-heavy assets. Nominal spread is unreliable whenever expected life is unstable, and OAS comparisons require consistent prepayment and volatility assumptions.

What are the limitations of structured credit waterfall analysis?▼

Strong enhancement can obscure weak collateral if loss timing and severity exceed structural assumptions. Prepayment and extension models are approximations, and test cushions can look healthy while deteriorating in trajectory, so trend matters as much as current headroom.

How do I evaluate a special servicer in a CMBS deal?▼

Assess workout timeline benchmarks by property type, conflict of interest exposure such as B-piece affiliation, and fee structure alignment with investor outcomes. Rising special servicing rates and extended resolution timelines are leading indicators of subordination erosion.
