Stress Testing
• Specific Applications
– Credit Loss / Loan Losses
– Interest Rate Sensitivity – Asset Liability Management
• Comprehensive
– Capital Adequacy
– Scenario-based, Regulator-defined
– Required for larger institutions (CCAR and DFAST)

Regulators’ Definition
• Stress testing is a forward-looking quantitative
evaluation of stress scenarios that could impact
a banking institution’s financial condition and
capital adequacy.
– based on assumptions about potential adverse external events,
such as changes in real estate or capital markets prices
– most useful when it reflects the characteristics particular
to the institution and its market area
– can be used to evaluate credit risk in the overall loan
portfolio, segments of portfolios, or individual loans

Regulators’ Definition
• Stress tests can be used to evaluate whether
existing financial (such as capital and liquidity)
and operational (such as staffing and internal
systems) resources are sufficient to withstand an
economic downturn or unexpected event.

What are Regulators’ Expectations?
13. © Copyright 2015, Trepp LLC13
Regulator Expectations
1. Repeatable, defensible
• Won’t fly anymore: “We think using 1.5x our loss experience
during the downturn will be sufficient.”
2. Forward-looking, scenario-based forecasts tied to
macro-economic inputs
• Usually means quantitative/regression models
3. Management and Board buy-in
• Board is “ultimately responsible”
4. Documented and Tested
• Process is as important as the results
• If it’s not in writing, it doesn’t exist
14. 14 © Copyright 2015, Trepp LLC
"... stress testing has fundamentally changed the way we think
about capital adequacy. The need to specify scenarios, loss
estimates, and revenue assumptions--and to apply these specifications
on a dynamic basis--has immeasurably advanced the regulation of
capital adequacy and, thus, the safety and soundness of our financial
system."
“… the single most important
advance in prudential regulation
since the crisis.”

Loan Models: PD, LGD, EL
• Probability of Default
– Likelihood ranging from 0% to 100%, over time
– Cumulative PD from 0% to 100%
• Loss Given Default
– Loss severity
– How large is the loss in the case of default
• Expected Loss
– PD * LGD * Outstanding Loan Balance, over time.

CECL: Current Expected Credit Loss Model
• FASB: Proposed Accounting Standards Update
(Subtopic 825-15), announcement expected in Q3 2015
• Transition period through January 2018
• Loss Reserve based on forward-looking, "life of loan"
assessment
• Acceptable methods include probabilities of default,
historical loss rate averages, discounted cash flows
39. © Copyright 2015, Trepp LLC39
CECL Impacts
• Audit and disclosure needs will increase
• Preparation: Data collection and aggregation across
multiple platforms
• Implementation of a model or system that can account
for analytics, compliance, and reporting
• OCC has estimated ALLL increases of 30 to 50%
• Bankers tend to believe 50% increase

How Do I Get Started?
Since regulators will be redefining stress
scenarios over time, you want your
solution to be flexible, allowing for a
wide range of scenarios and
assumptions
All capital adequacy models should be
treated as a long-term and integral part
of any strategic planning process
All capital adequacy models should be
aligned with bank management’s
forward looking business assumptions
42. © Copyright 2015, Trepp LLC42
How Do I Get Started?
Make sure you have access
to your
internal data
If building your own models,
make sure you have access
to the right external data
What data do I need? Is the data reliable?
43. 43 © Copyright 2015, Trepp LLC
• Time can be a resource or a constraint
• Starting early opens more options
• Determine needs
• Develop and stay within budget
