This document summarizes techniques for estimating claim liabilities, including the loss development factor method, Bornhuetter-Ferguson method, Cape Cod method, and Benktander method. It provides examples of loss triangles and calculations for each technique. Key steps include developing loss development factors from historical data, selecting development factors, and calculating unpaid losses. More advanced techniques address issues like changing inflation, trends, outliers, and tail estimation. Communication with claims and underwriting is emphasized.

Presentation by Michael-Paul James
Presentation on Property–Liability Insurer Reserve Error: Motive, Manipulatio...Michael-Paul James
The document summarizes a research paper that examines hypotheses for property-liability insurer reserve errors. It analyzes two measurements of reserve error and tests four main hypotheses from the literature - taxes, income smoothing, rate regulation incentives, and financial weakness. The results found that the choice of reserve error measurement impacted the findings. There was little evidence for income smoothing. Evidence supported overreserving for tax purposes under one measurement but not the other. Rate regulation incentives were supported. Financial weakness was linked to underreserving rather than deception.
Living Longer At What Price- Incorporating Longevity into a Risk Management M...Redington
This document discusses incorporating longevity risk into a pension scheme's risk management model. It provides analysis on:
- Adding longevity risk to Value-at-Risk (VaR) calculations, which increases total risk by 3.5-17.1% depending on hedging.
- Risk type contributions, where longevity risk alone increases total risk by 0.53% assuming zero correlation.
- Hedging ratios, where actual mortality experience above assumptions reduces hedging ratios.
- LE01 analysis to identify members most sensitive to longevity risk.
- Redington analysis on solutions like partial buyouts and customized hedging strategies.
3 4 how financial statements are used in valuationJohn McSherry
This document discusses lectures 3 and 4 on multi-period valuation models using cash flow and accrual based approaches. It covers the dividend discount model (DDM), including variations like the two-stage DDM and H-model DDM. It also discusses the discounted cash flow (DCF) model and how to calculate free cash flow to the firm (FCFF) and free cash flow to equity (FCFE). Key valuation issues discussed include forecasting horizons, terminal values, and discount rates.
ACHS Spring 2019 Long Duration GAAP Targeted Improvements - Market TrendsGuillaume Briere-Giroux
The document discusses trends in the actuarial labor market in the United States. It finds that there is currently a shortage of around 1,000 qualified life actuaries due to several regulatory changes increasing demand, including FASB target improvements, PBR, IFRS17, and PCAOB guidance. The supply of new life actuaries has been increasing at a steady rate of around 450 per year through organic growth, but this is insufficient to meet the additional demand of around 1,600 actuaries driven by these regulatory changes over the next few years. This is leading to a "race for talent" and rising costs for top actuaries. Potential solutions discussed include tapping actuaries from other practices, international mobility, and leveraging
The document discusses an investment strategy that utilizes quantitative techniques to generate alpha from multiple uncorrelated signals. It examines factors like valuations, momentum, and reversions across equities to construct a market neutral portfolio. The strategy aims to maximize returns while minimizing risks by optimizing weights between the various alpha signals. It takes a rules-based approach to ranking stocks and implementing the portfolio.

Open Collaboration in the Development of Innovative Online CurriculumEstela Dauksiene
The document discusses the OpenPROF project, which aims to foster open international collaboration among professionals to develop innovative online curriculum for work-based learning using open educational resources (OER). So far, the project has created 3 training materials on OER and developed 24 OER in English and 6 courses for work-based learning including OER available on their website. Some challenges have included the need for virtual and in-person collaboration as well as translation of materials into different languages. Requirements for teachers participating include digital skills, openness, and a willingness to collaborate and innovate.
This document summarizes the results of the University of California's "Be Smart About Safety" (BSAS) program from fiscal years 2005-2010. Some key points:

How to Determine the Right Measure of LossLibby Bierman
1. Sageworks is a financial information company that provides credit risk management solutions and data to over thousands of financial institutions.
2. The presentation discussed different methods that banks can use to measure loan losses, including historical loss rates, migration analysis, and PD/LGD models.
3. The speakers emphasized the importance of carefully analyzing a bank's portfolio performance and selecting loss measurement methods that accurately estimate expected losses.
This document provides an overview of key concepts in credit risk management, including:
1) Credit risk arises from factors like a borrower's ability to repay, economic conditions, specific events, and regional factors. It is the risk of financial loss if a counterparty fails to meet contractual obligations.
2) Banks assess probability of default, exposure at default, and loss given default to measure and manage credit risk. Transition matrices track how probabilities of default change over time.
3) Credit risk arises in both a bank's trading book (exchange traded and OTC derivatives) and banking book (loans and off-balance sheet commitments). Credit ratings and market prices help estimate probability of default.

In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.

Assumes Rate at which losses are paid (or incurred) is
constant
Does not handle changing inflation, trend or mix of business
well
Can lead to volatile results
Reduces Volatility in Claim Liability Estimate
Ignores Recent Experience in estimating Claim Liability
Not always clear what to use for a priori
Uses Experience to estimate the a priori Loss Ratio
Allows the a priori to vary by Accident Year
Apply BF. Use the Ultimate from BF as a priori, and apply BF
again
Optimal – in the sense that it has very low MSE of the
estimate vs. the actual result
More Stable then LDF, and considers actual
experience to date

• BF is the weighted average of DFM and the Loss Ratio Method
• Benktander is weighted average of DFM and BF
• In both cases DFM gets the weight %

Estimating
the Tail
3 way
Parameters
Given: Mean and Variance for Incremental Loss in each Cell
Residuals: for each historical cell
Sample the residuals to create a sampled historical triangle
Forecast Claim Liability based on the historical triangle (DFM,
BF, etc.)
Do this multiple times to determine a distribution
of the Claim Liability
Curves
Extrapolation
Model 3 Dimensions: Row (AY), Column (Age), Diagonal (CY)
Able to handle changes in CY Trend and portfolio mix
Difficult to fit – since there can be so many parameters
Bootstrapping
Forecast # of Unpaid Claims & Severity; Multiply
Severity depends on Accident Year and Age
Explicit Inflation assumptions can be used

They are the closest to any changes in loss trends
Inform you of any changes to their process
Can work with them to gain knowledge of the Life of a Claim
Listen to Product Management. They know changes to their
product better than anyone else
It’s not good enough to say the LDF is higher – Why is it
higher?
If Product fights you, you will do better if you understand their
business
Engage the actuary in discussions about your book
You don’t always know which bit of information is useful to her
Be Respectful and Honest. The actuary will value your opinion
Coverages may have different behavior (Auto PD vs TPL)
A group of similar policies may have undue influence
on the rest of the book
