Q

Contrast CAT Bond with traditional reinsurance

A

Credit Risk:
-CAT bonds are much safer since they are fully collaterized
-Reinsurance credit risk is a major concern at this magnitude
Cost:
-Highest layers usually have the highest profit margins
- Investors will accept lower spreads from CAT bonds since they offer diversification benefits (low correlation with investment returns)
Negociation
-Multi year bonds are available
-Reinsurance is usually only offered for one year period

Q

List advantages of using Freq/Sev distributions instead of Loss Reserve Distribution Models in quantifying u/w risk

A
  • It is easier to account for growth in the volume of business/inflation can be more accurately reflected
  • Changes in limit and deductibles can be more easily reflected
  • The impact of deductibles on frequency can be accounted for
  • The treatment of the split of loss between insured, insurer & reinsurer can be mutually consistent

Q

Describe two issues why comparing RAROC with cost of capital determined by CAPM or Fama-French model

A
  • Risk in CAPM is the systematic risk associated with an investment. RAROC risk is based on the difference between the cash flow’s expected value and the values in the tail.
  • The denominator of the RAROC calculation is understated, since it does not account for the
    franchise value.

Q

What happens to capital requirement under lognormal distribution of LOSSES (vs normal) in the EPD method

A

It increases, where the difference increases as the coefficient of variation increases. This is because the probability of large losses is higher under lognormal (higher tail)

A
  • The standard needs to be the same for all types of insurers (personal vs commercial; primary vs reinsurers)
  • The RBC needs to be objectively determined (2 insurers with the same risk exposure need to have the same RBC requirements)
  • The approach should be able to distinguish between items that differ materially in level of riskiness

Q

How can the EPD value be compared to an option depending on the riskiness of asset and liabilities?

A

Liability is risky and the asset riskless:
Call option on the losses with exercise price equal to the value of the assets at the end of the year.
Assets are risky and liabilities riskless:
Put option on the ending assets: because in the event where the asset value (stock price) is less than the
liability (exercise price), the difference will be β€œput” to the policyholders.

Q

Describe the exceedance probability method in capital allocation

A

The appropriate amount of capital for each line is the amount which will equalize the exceedance probability among lines. Because the expected losses between lines usually differ in size, the above equation is usually adjusted to express everything in terms of ratios to expected loss: 𝑃[πΏπ‘œπ‘ π‘ π‘–πΈ(πΏπ‘œπ‘ π‘ π‘–)>1+𝐢𝑖𝐸(πΏπ‘œπ‘ π‘ π‘–)]=πœ€π‘–

    Allocates the total risk capital in proportion to the separate risk measures
  2. Incremental Allocation
    Allocate capital based on the marginal impact on risk capital due to adding the entire line
  3. Marginal Allocation
    Marginal impact on risk capital due to increasing the
    exposure of the line by incremental portions
  4. Co-Measure

Q

List reasons why subprime repackaged mortgage (CMOs) were biased against investors

A
  • Higher probability of default due to lower credit quality of borrowers
  • Lower recovery values, because when the assets do need to be sold, they are often sold under financial pressure
  • High level of default correlation due to pooling mortgages from similar geographic areas/vintages.
  • Due to the CDO2 structure, the impact of errors in the estimates is magnified.

Q

Describe catastrophe risk swaps and its advantages/disadvantages

A

Swap between 2 (re)insurers which are exposed to
different types of catastrophic risk. The swap defines a specified amount of money that needs to be paid by each reinsurer in the occurrence of a specified event

A:

  • The (re)insurer reduces some of its core risk, and achieves diversification
  • Lower transaction costs than some of the other securities

D:

  • It is difficult to create a swap that achieves parity
  • Can create more exposure to basis risk that some other types of contracts
  • Not prefunded

Q

Describe 3 methods to quantify dependency in CAT models (and disadvantages)

A
  1. Empirical analysis of Historical Data.
    Disadvantages include:
    a. usually there is insufficient data to calculate the historical dependency
    b. there is little insight as to how the dependencies will change during tail events
  2. Subjective Estimates: advantages include:
    a. can account for the tail events
    b. reflects the user’s intuition
    Disadvantages include:
    a. the number of risk categories increases, the number of dependency parameters that need to be estimated increases exponentially
  3. Explicit Factor Models: these link the variability of the risks to common factors

Q

List 2 disadvantages of bond default probabilities as a threshold for risk measures

A
  • Does not address which credit rating should be targeted
  • Does not account for the risk of downgrade

Goldfarb

36
Q

Describe ways to derive the threshold for risk measures used in determining capital

A
  • Bond default probabilities at a Selected Credit Rating Level: capital to keep probability of default of the firm equal to the probability of default of a bond with a specific credit rating.
  • Management’s risk preferences: a threshold based on the risk tolerance of management.
  • Arbitrary default probability: an arbitrary percentile that is relatively easy to measure. No need to estimate values at very low probability of occurrences, where a lot
    of uncertainty exists.

Goldfarb

37
Q

Describe 3 unique aspects of reinsurance recoveries that makes it difficult to estimate credit risk

A
  • Definition of β€œdefault” : consideration to impact of reinsurer credit rating downgrade in capacity to pay full value of losses
  • Substantial contingent exposure: insurer’s adverse development may increase recoverables and therefore exposure to credit risk
  • Reinsurance credit risk is highly correlated with the underlying insurance risk

Goldfarb

38
Q

Describe catastrophic equity puts and its advantages/disadvantages

A

It’s an option. The insurer purchases the put from the writer, and in return, receives the right to issue
preferred stock to the writer at a specified price on the occurrence of a specified event.
A:
- The insurer will be able to raise equity after a catastrophe, when its stock price is likely to be
depressed
- Lower transaction costs than CAT bonds, as no need to form a SPR
D:
- Not collateralized, so exposes the insurer to credit risk
- If the insurer issues preferred stock, the value of the existing shares will be diluted

Cummins_Capital

40
Q

List disadvantages of management’s risk preferences as a threshold for risk measures

A
  • will be difficult to get management to articulate and agree on a threshold
  • May differ to the preferences of directors and shareholders
  • ignores risk, which is an important consideration to compare to reward
  • managers will likely be focused on a number of issues that concern policyholders, and it may be hard to isolate the estimate of the threshold to just the probability of default

Goldfarb

41
Q

How are Asset backed securities CDO created and why?

A

Due to the high level of risk, mezzanine tranches are often difficult to sell. In order to sell these, some
dealers have repackaged mezzanine tranches from several different asset backed securities into a new
ABS

Coval

42
Q

Explain why a loss would receive a higher allocation in the upper layers than in the lower layers in the capital allocation by layer method

A
  • There are a fewer events that pierce the layer (Losses divided into fewer losses)
  • The layer of capital is wider because the incremental increase to severity of each event tends to increase in size. (Usually losses at higher percentile rare but severe)

Bodoff

43
Q

Give exceedance probability method of capital allocation advantages and disadvantages

A

A:
- Consistent risk measure that can be used to compare between LoB, companies, etc.

D:

  • The firm may not have enough capital to achieve a certain exceedance probability
  • This approach does not consider the impact of diversification
  • This does not reflect the amount by which losses will exceed the resources in the event that the exceedance level is breached

Cummins_Capital

44
Q

Describe some reasons why structure finance market grew substantially in the years leading up to the 2008 crisis

A
  1. Seemingly attractive yields: Biased by historical default rate and failed recognition of high systematic risk assumed
  2. Extreme market optimism: Housing prices would keep increasing and subprime mortgage default rates would stay low
  3. Too little appreciation for fragility of ratings:
    Very sensitive to assumptions. Capital requirements and decisions based on them.
    4.Perverse incentives for rating agencies: Paid by issuer, not investors
  4. Perverse incentives for banks: Collected huge fees for creating the structured finance products.

Q

Describe and give advantage (1) and disadvantages of the Risk-based capital (RBC) method of capital allocation

A

This is the level of capital that must be held in order to avoid regulatory intervention.

A:
Relatively simple to calculate and find input value
D:
- Factors used in the derivation of the RBC are of questionable accuracy
- Calculations are often based on book value instead of market
- RBC ignores several important sources of risk

Cummins_Capital

49
Q

Describe the main advantage of Industry Loss Warranties (ILW)

A

There is a possibility that the risk linked securities may not be treated as reinsurance by regulators.
An ILW is one type of security that does not suffer from this problem

Cummins_CAT

50
Q

Briefly describe risk measures used to derive the necessary amount of capital

A
  • Percentile Risk Measure: provides the capital required to achieve a certain probability of ruin.
  • Conditional Tail Expectation (CTE): the mean loss of all the losses that exceed a certain percentile. (TVaR)
  • Expected Policyholder Deficit Ratio: discussed in Butsic. This metric is less arbitrary than CTE (no percentile)

Goldfarb

51
Q

List 3 type of indices in an index trigger in CAT bond

A
  1. Industry loss indices: Estimated losses to the industry
  2. Modeled loss indices: output from a model of CAT modeling firm to generate either industry losses or losses speciific to a sponsoring insurer
  3. Parametric indices: triggered by specified physical measures of an event (weather related measures)

53
Q

Describe different participants interactions in the structure of a typical bond

A

Insurer:
- Pays premium to SPR
- Receives fund from the SPR if CAT occurs
SPR:
-Sells bond to investors and invest proceeds in highly rated (safe) investment
-Collects premium from insurer and pay in case of CAT
-Return money to investors if not CAT occurs
Investors:
-Provide initial funds to SPR (bond price)
-Receive interest payment and principal at maturity if no CAT
Trust account:
-SPR maintains fund in trust account until it is paid out

Cummins_Capital

55
Q

Give 2 ways to reduce basis risk in CAT bonds and make it a less speculative instrument

A
  • Base the payment on narrowly defined geographic indices
  • Dual-trigger contracts (where the insurer cannot collect more than its net loss)

Cummins_CAT

56
Q

Describe moral hazard and basis risk in CAT bonds

A

Moral hazard: the risk that the insurer may artificially increase the losses in order to qualify for
reimbursement (H: Indemnity L: Parametric, Modeled)
Basis risk: the risk that the defined trigger is not very closely related to the insurance company’s
exposure (H: Parametric L: Indemnity)

Cummins_CAT

57
Q

List advantages of sidecars

A

A:

  • Transactions are usually off-balance sheet, and therefore the sidecars can be used to improve the reinsurer’s leverage
  • Can be formed quickly with minimal documentation/administration costs

Cummins_CAT

58
Q

List the advantages of capital allocation by layer

A
  1. Allocates capital to the entire range of loss events (not only extreme)
  2. Tends to allocate more capital to events that are more likely
  3. Tends to allocate significantly more capital to events that are more severe
  4. Eliminates the need to select an arbitrary percentile level as a basis for allocating capital
  5. Always allocate 100% of the capital

Bodoff

59
Q

Describe risk-linked securities

A

Risk linked securities enable insurance risk to be transferred to the capital market, providing the
insurance market with additional capacity: catastrophes that are large relative to the resources of
insurers will often still be small relative to the size of capital markets.

Cummins_CAT

60
Q

List and briefly describe the 3 components of loss reserve risk (from insurance risk)

A
  • Process risk: risk that actual results will deviate from their expected value due to the random variation inherent in the claim development process
  • Parameter risk: risk that the actual expected value of the liability differs from the actuary’s estimate of the expected value due to inaccurate parameters
  • Model risk: risk that the actual expected value of the liability differs from the actuary’s estimate of the expected value due to the use of the wrong model

Goldfarb

61
Q

Briefly describe methods to estimate u/w risk (from insurance risk)

A
  • Loss ratio distribution model
  • Frequency & severity model: Construct an aggregate distribution based on separate frequency and severity models.

63
Q

What was the consequence of the increase of non-conforming mortgages and decreasing quality of subprime borrowers

A
  • Ratio of mortgage values to home prices increased

  • Increased issuance of mortgages with low/no documentation

Coval

64
Q

What is Bodoff proposal for the new definition of VaR?

A

Hold enough capital EVEN for the 99th percentile. This means losses below the percentile selected is also considered

Bodoff

65
Q

Describe different risk-based capital measures

A
  • Regulatory Required Capital (min. requirements)
  • Rating Agency Required Capital: to achieve a specific credit rating
  • Economic Capital: the amount of capital necessary to provide the firm with a certain probability of achieving a specific objective over the time horizon.
  • Risk Capital: the amount of capital that needs to be provided by the shareholders to cover the risk that the liabilities may exceed the funds already provided

Goldfarb

66
Q

What are the assumptions made in order for ABS to be rated AAA?

A
  • Rating based on anticipated likelihood of default
  • Assume that these high risk assets are not correlated to each other and with the market as a whole
  • Senior tranches are safeguarded by junior tranches (true if uncorrelated)

Coval

67
Q

Why is historical experience from catastrophe events less reliable for future losses

A
  • Events are rare
  • Exposures change over time
  • Severities change over time due to changes in the building materials & designs

Goldfarb

68
Q

Define sidecars in risk linked securities

A

These are special purpose vehicles formed by insurers or reinsurers to provide additional capacity to
write reinsurance.
Sidecars are mainly capitalized by private investors, but can be funded by insurers and reinsurers as
well.

Cummins_CAT

69
Q

List and briefly describe 3 frictions costs that reduce the return on capital of a line of business

A
  1. Agency & Informational costs: management may behave opportunistically, and therefore fail to achieve the owner’s objective value maximization
  2. the current tax system results in double taxation: investing in securities via insurance companies produces lower after tax returns than purchasing the securities directly
  3. Various regulations may force the insurer to hold inefficient investment portfolios. Note that for most insurers, this generates no real cost, as they generally would hold more capital than the regulatory requirement anyway

Cummins_Capital

70
Q

List problems with looking at change in value of insurance liabilities over a year only

A
  • There is little available methods/data to estimate the timing of the recognition of adverse loss
    development
  • The β€œchange in value” perspective for loss reserves will not be totally consistent with market risk, as it will most likely focus on the best estimate of the reserve. Market risk, which is based on market value, includes a risk margin
  • The information that would result in the revaluation of the liabilities is often not available over the short term

Goldfarb

71
Q

Describe the condition in ILW for payment to be made and 2 categories of payment that can be made

A

This security has dual-triggers that need to be satisfied for the loss to be paid:

  • Retention trigger: based on the incurred loss of the insurer
  • Warranty trigger: based on an industry wide loss index

ILWs have 2 categories of payments that can be made:

  • Binary trigger: full payment is made once both triggers are satisfied
  • Pro rata trigger: payoff depends on the magnitude by which the loss exceeds the warranty

Cummins_CAT

72
Q

List the advantages of a SPR in a CAT bond

A
  • Shields the investors from general business risk of the insurer
  • Financing costs for the issuer will be lower
  • Transaction cost is more transparent than a debt issue since funds are in a trust and released according to specific criteria

Cummins_CAT

73
Q

Describe different income measures used in the RAROC calculation

A
  • GAAP Net Income: calculated using GAAP accounting. (management decisions)
  • Statutory Net Income: calculated using Statutory accounting rules
  • IASB Fair Value: based on Fair value accounting. Removes the accounting biases of various accounting conventions
  • Economic Profit: the change in β€œeconomic value” of the firm over a period (assets are recorded at market value, and liabilities are discounted).

Goldfarb

74
Q

Describe two objectives possibly targeted by economic capital

A
  • Solvency objective: that the firm can meet its existing obligations to policyholders
  • Capital Adequacy Objective: that the firm can continue to pay dividends/grow premiums/maintain a certain financial strength

Goldfarb

75
Q

Explain why it may be appropriate not to allocate 100% of available capital (M-P method)

A
