The maximum loss that an insurer can expect to incur on a policy is known as the probable maximum loss (PML). The term “probable maximum loss” (PML) is most commonly linked with property insurance coverage, such as fire or flood insurance.
How is PML calculated in insurance?
To calculate the likely maximum loss, multiply the property value by the highest projected loss percentage. For example, if the property is valued at $500,000 and fire risk mitigation decreases predicted losses by 20%, the probable maximum loss in the event of a fire is $500,000 multiplied by.
What is EML and PML?
Insurers and insureds share the risk of economic loss based on a decision process that typically involves the use of modeling to evaluate the amount to which a property can be destroyed in the case of a threat. The Probable/Possible Maximum Loss (PML) and Estimated Maximum Loss (EML) scenarios are commonly used to understand the severe effects of losses for a particular risk.
On the basis of theoretical understanding of the risk and exposure, EML/PML studies cannot be accurately developed. Instead, these investigations necessitate a thorough grasp of real-world circumstances that influence the extent of the loss.
We’ve created an approach that depends on solid information from insurers and their clients to remove the uncertainty out of the EML/PML calculation process throughout the years. The following items are included in the scope of our investigation:
- Getting enough information to evaluate the methods and processes utilized in a particular risk. This could contain overall plans that show where important pieces and surrounding properties are located.
- Obtaining and confirming cost data that includes a breakdown of various parts such as buildings, equipment, and other things.
- Hazards and risks that cause physical harm to property and infrastructure are assessed.
- In order to assess the repercussions of a loss, hazards and risks are ranked in order of their severity and impact.
- Analyzing interdependencies to determine the impact of dangers on operations and the property’s overall viability.
- Considering the possibilities for restoration and the costs involved in restoring a property to its pre-loss form.
What is a good PML?
Structured finance is back, and with it comes all of the due diligence requirements, including the Probable Maximum Loss Report, which is frequently misinterpreted. To effectively use the Probable Maximum Loss Report as an underwriting tool, credit officers and underwriters must first grasp a few fundamentals.
The purpose of the seismic risk rating procedure is to safeguard your portfolio and downstream investors against a double dose of seismic risk. The PML Indicate can’t totally eliminate the risk of a seismic eventwe don’t report the asset’s location from a nuclear reactorbut it can fail structures that are the most vulnerable during an earthquake. Note that lenders who do not demand PMLs may experience adverse selection in their portfolios, resulting in a double dose of seismic risk.
A lender must be consistent while using the Probable Maximum Loss Report. If you’re going to measure something, make sure you use the same procedure each time. So, here are four fundamental measures to achieving consistency.
SEL vs. SUL is a debate that has been going on for a long time. Learn the following fundamental vocabulary: The Probable Maximum Loss for an asset can be expressed in two ways: the Scenario Expected Limit (SEL) and the Scenario Upper Limit (SUL). During the 475-year seismic event, an engineer creates a curve of expected outcomes (see picture). The Scenario Expected Limit is in the middle of the curve, and the Scenario Upper Limit is when 90% of the expected outcomes are lower. These statistics are not contradictory; they are simply two different ways of representing the same curve.
PMLs now have new ASTM standards.
The ASTM E2026-07 Standard Guide for Seismic Risk Assessment of Buildings and the ASTM E2557 Standard Practice for Probable Maximum Loss (PML) Evaluations for Earthquake Due-Diligence Assessments were both released in 2007.
The SEL should be considered as the PML by CMBS lenders, according to ASTM E2557. The SEL should be compared to 20% structures with a SEL of more than 20% usually require some type of mitigation. Mitigation might take the form of structural (seismic retrofit) or financial (financial) measures (earthquake insurance).
PMLs should be improved.
These new ASTM Standards make the process better, yet they’re too flexible.
The guidelines, for example, do not specify how an engineer should compute a PML, and some engineers perform calculations that are outside the mainstream, or worse, do no arithmetic at all; they simply call it based on their judgment.
Of course, my colleagues may be excellent engineers, but the industry need objective seismic risk assessment. The procedure should be open to public scrutiny and peer evaluation.
objective and dependable Probable Maximum Loss Reports are simple to produce; all we need is a little input from our clients. Clients must, indeed, play a role. We’ll be more than halfway there if clients require the following:
1. Only order reports from companies that employ registered engineers.
2. Require the engineer to demonstrate his or her arithmetic skills;
3. Require the engineer to provide the Scenario Upper Limit as well as the Scenario Expected Limit.
For numerous lenders, I helped write the Probable Maximum Loss Scope of Work, and my rationale for my suggestions is detailed in my RMA Journal article titled Managing Seismic.
The main purpose is to safeguard your portfolio from undue seismic risk by continuously using the Probable Maximum Loss report as an underwriting tool, rather than by predicting the future.
Why is PML important?
By William Raichle, Vice President of ISO Risk Decision Services, and John Vorbeck, Manager of ISO Risk Decision Services’ Risk Engineering Group
Whether protected independently or as part of a package, fire is generally regarded the most essential hazard in the underwriting process. Underwriters assess the Probable Maximum Loss when comparing possible losses between buildings and when appraising a single building (PML). The most popular definition of PML, and the one adopted by ISO for commercial fire purposes, is an estimate of the highest loss a building or a business in the structure is expected to sustain as a result of a single fire, given that existing mitigating elements are functioning properly (sprinklers, local fire department response, etc.). The PML is commonly represented as a percentage of the building’s value or as a monetary amount. The majority of PML calculations and analytics are based on engineering.
Underwriting choices are frequently influenced by PML analytic analyses as well as the amount of reinsurance surrendered on a risk. However, the degree to which such decisions are influenced by PML varies by insurer. It deserves a broader audience, in part because the difference in PML among otherwise similar-looking property hazards is simply too enormous to overlook.
When preparing PML assessments, ISO’s engineering team takes into account differences in construction, occupancy, and fire protection.
Construction
- Consider combustible, noncombustible, and fire-resistant components while designing floors and roofs.
- combustible expanded plastic insulation and outside insulation finish systems are examples of specific features to be concerned for (EIFS)
- Taking into account the mitigating effects of fire walls in restricting the spread of fire damage to a single region, building size
Occupancy
The combustibility of contents, which measures the fire-loading effect of contents on building structure damage, and the susceptibility of contents, which measures damage to merchandise or materials from direct or indirect effects of fire, smoke, and/or water, should both be considered during occupancy. Food-related occupancies have a disproportionately high risk of loss. Clothing and gadgets, for example, lose their worth over time and you may not be able to return them to their previous state.
Fire Protection
Both private and public fire protection features are available. Automatic fire-detection services and automatic fire sprinkler systems are examples of private, on-site protection. The sprinkler component might simply be determined by the presence or absence of such a system. It can also take into account additional parameters from the ISO Automatic Sprinkler Grading, such as the system’s suitability for the building’s and contents’ prospective demands, its relative reliability, system component maintenance records, and unsprinklered regions. The need for sprinkler systems may be determined using the National Fire Protection Association’s occupancy classifications.
- Light Hazard occupancies include places like churches, schools, and workplaces where the amount and/or combustibility of the items is modest and flames generate comparatively low rates of heat.
- Dry cleaners, libraries with extensive stack room areas, and markets are examples of Ordinary Hazard Group 2 occupancies with moderate to high contents combustibility.
- Extra Hazard Group 1 includes occupancies with very high contents combustibility, such as die casting, plywood production, and printing, where dust, lint, or other materials pose the risk of rapidly developing fires with high rates of heat release (using low-flash-point inks).
The protection given by the responding local fire department, as well as its availability to water supply for fire suppression, are factors in public protection. The at-risk ISO Public Protection Classification is usually taken into account in this research (PPCTM).
Interdependencies
Depending on the construction, occupancy, and protection, the damage to the building structure will vary substantially. A match manufacturing firm in a frame building with no sprinkler system in a PPC 9 fire zone, for example, is significantly more likely to suffer a maximum loss than a fully sprinklered, fire-resistant office building in a PPC 3 neighborhood.
Non-sprinklered apartment complexes, condominiums, and hotels with well-compartmentalized rooms and apartments are typically intended to contain a typical fire to the room or apartment where it started.
In partial-loss instances, zoning changes may come into play, preventing you from rebuilding or restoring a specific type of structure or occupancy. In other circumstances, contamination as a result of a fire could cause considerable environmental damage. Changes in occupancy may have an impact on the possibility for loss. It’s possible that a mill-style structure that’s presently only utilized for routine hazard storage was once employed for manufacturing. Oil-saturated wood flooring may no longer be visible, but they nevertheless add to the fire load.
Better Underwriting Decisions
PML analytics and evaluations give valuable information that can assist insurers in recognizing their risk of extraordinary losses. Insurers who use PML in their underwriting criteria will be able to better comprehend the scope of the risk and manage it through hazard and loss evaluations. PML’s analytical tools also assist insurers in determining the underlying objective of corporate underwriting standards, determining the amount of reinsurance required, and satisfying reinsurance agreements, resulting in improved underwriting decisions.
What does PML stand for?
Progressive multifocal leukoencephalopathy (PML) is an acronym for progressive multifocal leukoencephalopathy. It’s a dangerous virus that attacks the central nervous system. The virus targets myelin-producing cells. Myelin is a fatty material found in the brain that coats and protects nerve fibers and aids in the transmission of electrical signals. PML can cause symptoms to appear in almost any part of your body.
PML is an uncommon disease. Each year, roughly 4,000 persons in the United States and Europe contract PML. It’s a potentially fatal ailment.

Loss dimensions
Determining the size or quantum of prospective loss is one of the most significant factors.
When viewed from the inside, this provides a context against which risk management activities can be judged.
When observed from the outside, it becomes a starting point for the insurance market to assess risk.
The following measures are suggested in order to better properly reflect the potential loss:
Normal loss expectancy (NLE) Expected aggregate annual loss Full asset value (FAV) Maximum anticipated loss (MFL) Estimated maximum loss (EML) Normal loss expectancy (NLE) Expected aggregate yearly loss (EAAL)
them. It is generally less than a total loss and the maximum foreseeable loss.
Insurers usually use the EML amount as the reasonable limit of maximum exposure while allowing the possibility of a larger maximum loss.
It is important to undertake the following when determining the fire and explosion MFL/EML, for example:
Divide the risk into fire zones, which are defined by one or more buildings/compartments that are not physically or spatially isolated.
Determine the fire region with the greatest potential loss, taking into account the fire load and possibility of explosion, as well as the plant/goods’ vulnerability to smoke, water, corrosion damage, and other factors.
Calculate the maximum MFL/EML that can be sustained. (Continue reading on page 126.)
event, given that all risk control measures operate as expected.
One of the most critical loss estimations. If these losses are to be financed, the total of these losses must be calculated.
Loss frequencies and probabilities
connected to a loss The subject of likelihood of loss has several dimensions, including the frequency, relative frequency, and empirical probability of losses or events when expressed numerically.
In the risk assessment process, the extra dimension of frequency or chance of loss becomes the last component.
defined time or consequence interval.
Inductive probability theory proposes estimating a future event’s result based on its relative frequency of occurrence in the past.
The objective is to refer to the likelihood of an accident or event having an outcome of, say, X value, where such probability is assessed by examining the outcome’s relative frequency of occurrence – connected with an outcome.
Risk profiles
After completing a macro-risk identification exercise and determining the MFL, EML, and probability, they can be represented in a table and the risk profile of the organization calculated.
What is maximum foreseeable loss?
When an insured property is harmed or destroyed by an adverse event, such as a fire, the maximum foreseeable loss refers to the most significant financial impact a policyholder could face. The maximum foreseeable loss assumes a failure of the conventional precautions, such as sprinklers and expert firefighters, which would normally limit such a loss.
What is Estimated loss?
The sum of the values of all conceivable losses, each multiplied by the probability of that loss occurring, is the expected loss.
For a variety of factors, the projected loss on a loan changes over time in bank lending (homes, automobiles, credit cards, commercial loans, and so on). The majority of loans are repaid over time, resulting in a decreasing outstanding amount to be reimbursed. Furthermore, most loans are backed by pledged collateral, which has a different value over time than the outstanding loan value.
What does SEL mean in insurance?
Scenario Expected Loss » Resources » Glossary (SEL) One approach to quantify the Probable Maximum Loss value is the Scenario Expected Loss (SEL). The Scenario Predicted Loss is the average damage that a building is expected to sustain following a seismic event.
