Introduction

What are structured subprime RMBS portfolios?

What is “basis risk”?

Why is “basis risk” between these structures important now?

what are structured subprime rmbs portfolios
What are structured subprime RMBS portfolios?
  • Portfolio exposure to subprime Residential Mortgage-Backed Securities (RMBS) can be obtained using various structures:
    • Structured Finance Collateralized Debt Obligations (SF CDOs)
      • Cash SF CDOs
      • Bespoke SF CDOs
      • Hybrid SF CDOs
    • ABX.HE Indices
    • Tranche ABX.HE (TABX) Indices

what is basis risk
What is “basis risk”?
  • Basis risk describes the risk that offsetting investments in a hedging strategy will not experience cash flow or price gains in the same manner.
  • Basis risk has the potential to create an excess gain or loss and therefore is not directional. The amount of basis risk in a hedging strategy describes the how much risk is left behind due to imperfect correlation between the two investments.
  • Basis risk in subprime RMBS portfolios generally arises from:
    • Performance differences in the underlying portfolio assets
    • Structural differences in portfolio instruments
    • Liquidity differences in the different secondary markets
    • Timing of expected cash flows from the portfolio instruments

why is basis between these structures important now
Why is “basis” between these structures important now?
  • Standard tranches of the ABX.HE Index commenced trading on Feb. 14, 2007
  • Index tranches promise to provide:
    • Liquidity
    • Transparency
    • Standardization
    • Market Consensus
  • Motivations for TABX participation:
    • Hedging
    • Relative Value Trading
    • Benchmarking
    • Leveraged Market Positions

subprime rmbs 1014
Subprime RMBS 101
  • Standard Structural Features of Subprime RMBS
    • Subordination serves as credit enhancement to account for credit risk
    • Interest rate instruments to hedge interest rate risk
    • Performance test at three year mark
      • If test fails then the priority of payments remains unchanged with the senior notes receiving all principal proceeds
      • If test passes then principal proceeds repays subordinated notes until targeted subordination is met.
    • Defaulted loans worked out by servicers
  • Each Subprime RMBS will have somewhat unique performance profiles

www.derivativefitch.com

subprime rmbs 1015
Subprime RMBS 101

Principal Waterfalls

  • Sequential pay
    • All scheduled principal and prepayments go to repay the senior bond holders first until paid-in-full, then to the next senior note holder, etc.
    • Subprime RBMS are initially sequential pay for the first three years and will remain sequential pay if the performance tests fail
  • Credit Enhancement (CE) “Step Downs”, if performance tests pass
    • If overcollateralization (OC) targets have been met, the CE is stepped down by repaying subordinate bond holders.
    • OC targets are set to double the original subordination, ie. If the original ‘AAA’ bond subordination is 7.5% then the target is 15%
    • Test senior note target for compliance first and if passing then check the next senior bond and so on.
    • Over periods of rapid prepayments all bonds may be meeting the OC targets, then principal prepayments become inverse sequential pay.

Interest Waterfalls

  • Regular interest
    • Paid sequentially to bonds, capped at weighted average mortgage rate net of expenses (Net WAC) or available funds cap (AFC)
  • Excess Interest
    • Excess interest is the remaining interest proceeds in the interest collection account after paying bondholders regular interest above
    • First, excess interest is used to recover realized collateral losses
    • Second, excess interest is used to recover any interest shortfalls created where Net WAC is lower than the stated bond coupon
    • Finally, the remaining excess interest goes to the residual bond holder

AFC Interest Shortfall

  • AFC Shortfall is the difference between the stated bond coupon and the Net WAC
  • AFC Shortfalls accrue over time and may be recoverable
  • AFC Shortfalls manifest themselves in times of rising interest rates
    • Typical subprime RMBS deals have 75% hybrid ARM mortgages
    • RMBS bonds are generally floating rate bonds based on the London InterBank Offering Rate (LIBOR)
    • If short-term LIBOR interest rates rise during the 2- or 3-year fixed rate period then the interest coupon from the mortgages is insufficient to pay the RMBS bond holders LIBOR plus the stated spread
  • AFC shortfalls may be unrecoverable if excess interest is eroded.

credit default swaps 101
Credit Default Swaps 101

Protection Seller

  • Receives CDS premium payment and reimbursement payments in exchange for providing protection payments if a credit event occurs.
  • CDO note holders are protection sellers in a synthetic CDO.

Protection Buyer

  • Pays CDS premium in exchange for protection payments if a credit event occurs.
  • CDS Swap Counterparty is the protection buyer in a synthetic CDO.

Calculation Agent

  • Determines the amount of the protection payment upon a credit event per the terms of the credit default swap
  • Usually the Protection Buyer serves this role

www.derivativefitch.com

credit default swaps 1011
Credit Default Swaps 101

Collateral or Eligible Investment

  • Highly rated, highly liquid financial instruments purchased from the sales proceeds of the initial CDO notes.
  • Provides the index portion of the note coupon
  • Provides protection payments or the return of principal to note holders

Reference Entity and Reference Obligation

  • Reference entities are security issuers like a corporation or sovereign
  • Reference obligations are securities with specific debt seniority levels
    • Reference obligations in a corporate CDS is usually informational to establish the seniority of debt to be valued if a credit event occurs
    • Reference obligations in CDS of structured finance assets or leveraged loans or in total return swap structures

Credit Events

  • Applicable credit events will vary by CDS
  • Typical credit events may include:
    • Bankruptcy
    • Failure to Pay (FTP)
    • Restructuring
    • Repudiation/Moratorium, usually emerging markets and sovereigns only
    • Obligation Acceleration, usually emerging markets sovereigns only
  • Once a credit event has been called and settled then the credit default swap is terminated

www.derivativefitch.com

credit default swaps 1014
Credit Default Swaps 101

Settlement and Valuation Procedures

  • Protection Buyer calls a credit event by sending notice to the Protection Seller what credit event has occurred
  • Settlement method is determined by the CDS contract
    • Physical settlement means the Protection Buyer gives the Seller the reference obligation, or equivalent, in return for cash par amount
    • Cash settlement means the parties look to the market value of the reference obligation to determine the net protection payment
  • Fitch’s preferred valuation process includes:
    • Dealer poll of at least 5 dealers, not including the Protection Buyer
    • Polls typically held 30 to 60 days after credit event notification

ISDA Pay-As-You-Go (PAUG) Template 101
  • ISDA PAUG template is designed to replicate the cash flow profile of the cash bond with a credit default swap (CDS) contract
  • CDS contracts for corporate and sovereign issuers are insufficient to replicate the payment profile of a structured finance bond
  • ISDA PAUG template was introduced in the U.S. in XXXX 2005 for RMBS and CMBS securities for CDO securities in June 2006
  • Introduces the concept of “floating payments”
    • Floating payments are paid by the Protection Seller in the event of an AFC Interest Shortfall
    • Floating payments may be reimbursed by the Protection Buyer if the AFC Interest Shortfall is ultimately recovered

    • FTP Interest for CDO reference obligations only

PAUG Floating Amount Events

    • Interest Shortfalls
    • Principal Shortfalls
    • Writedown Amounts
  • Protection Buyers typically have an option whether to call a credit event or a floating amount event

www.derivativefitch.com

isda pay as you go paug template 1013
ISDA Pay-As-You-Go (PAUG) Template 101

PAUG Settlement

  • The secondary market for structured finance securities is not liquid and therefore valuation procedures are not applicable
  • Floating payments are designed to replicate the actual loss amounts
  • If a credit event occurs then the Protection Buyer has the option to physically deliver all or part of the notional amount to the Seller
    • If the entire notional is physically settled then the CDS is terminated
    • If a portion of the notional is settled then the CDS continues on the remaining amount

Interest Shortfalls

  • RMBS reference obligations are called AFC shortfalls
  • CMBS reference obligations are called WAC shortfalls
  • CDO reference obligations are called PIK-ing shortfalls

Interest Shortfall Cap Options

  • Fixed Cap: Floating payments are limited to the amount of the CDS premium
  • Variable Cap: Floating payment are limited to LIBOR + premium
  • No Cap: No limit to the floating rate payments
    • Completely replicates the payments of the cash bond or total return swap
    • May require principal to be liquidated to pay interest shortfall

subprime rmbs afc risk
Subprime RMBS AFC Risk
  • Available Funds Cap (AFC) Risk
    • REMIC law limits a floating rate RMBS bond pass-through rate to the lesser of:
      • Bond spread plus some index (typically 1 month LIBOR), or
      • Underlying mortgage collateral pool’s weighted average coupon, net of expenses (Net WAC).
    • AFC Risk varies by RMBS transaction based on:
      • Actual prepayment speeds of underlying mortgages
      • Effectiveness of interest rate hedges in the RMBS structure
      • Short-term interest rate increases before Hybrid ARM mortgages switch to floating interest rate payments

  • Cash SF CDO Asset Portfolio Highlights
    • Portfolios contain between 60 and 140 bonds
    • Assets may be diversified by market sector, however recent vintage SF CDOs have been concentrated in subprime RMBS
    • Assets may be diversified by risk profile (intial ratings)
    • Assets may be diversified by vintage
    • Asset acquisition and selection
      • Asset manager warehouses bonds prior to issuing CDO notes
      • CDO notes typically issued when asset manager has accumulated approximately 60-80% of the target portfolio
      • Initial portfolio is typically fully ramped within 6 months of CDO note issuance

structured finance cdos 1013
Structured Finance CDOs 101
  • Managed vs Static Portfolios
    • Static portfolios are typically fully ramped at closing and principal proceeds are used to amortize the senior notes
    • Managed portfolios are typically partially ramped at closing and principal proceeds are typically reinvested for a finite period between 3 and 6 years
      • If the portfolio experiences negative credit migration then discretionary trading is limited to “maintain or improve” credit quality
      • If the portfolio significantly under performs then the transactions may shift to a static portfolio

  • Cash SF CDO Note Highlights
    • Credit enhancement comes from subordination and excess spread
    • Interest is paid sequentially to note holders
    • Overcollateralization (OC) and Interest Coverage (IC) performance tests are checked prior to distributions to subordinate notes
    • Excess interest may be used to:
      • If tests are passing then distributed to Preferred Shares or Equity
      • A portion may be used to repay mezzanine notes
      • If tests are failing then distributions may be used to cure the tests
        • Purchase new assets
        • Pay down senior notes
