This FASB staff Q&A only focuses on the guidance in Topic 326, 
Financial Instruments—Credit Losses. This Q&A does not address other 
regulatory, rules, or compliance requirements that entities may need to consider 
when preparing and issuing financial statements.
 
Topic 326 contains 
a requirement of applying a reasonable and supportable forecast and, if 
applicable, reverting to historical loss information (if an entity is unable to 
forecast credit losses over the estimated life of the instrument) when measuring 
expected credit losses. As part of the Board's continuing commitment to educate 
stakeholders, the staff has developed this question and answer (Q&A) 
document to respond to some frequently asked questions about using historical 
loss information, developing reasonable and supportable forecasts, and 
requirements regarding applying the reversion to historical loss information. 
The staff encourages entities also to read the Staff 
Q&A Topic 326, No. 1, Whether the Weighted-Average Remaining Maturity 
Method Is an Acceptable Method to Estimate Expected Credit 
Losses, that was issued in January 2019.
 
For 
contextual purposes, this Q&A includes information from Accounting Standards 
Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326): 
Measurement of Credit Losses on Financial Instruments, and certain 
paragraphs in the basis for conclusions.
 
Update 2016-13 was 
developed to be operably scalable and flexible. An entity must apply judgment in 
estimating expected credit losses. An entity's estimate of expected credit 
losses should reflect its expectations or its best estimate of expected credit 
loss. All examples or numerical adjustments contained in this Q&A are 
intended for educational purposes. Consequently, numerical adjustments should 
not be misconstrued as a "starting point," that is, a required amount or the 
Board's expectation regarding the level of allowance for expected credit losses 
that a particular entity should record.
 
Does the application of the word forecast in paragraph 
326-20-30-7 infer computer-based modeling analysis is required?
No, developing forecasts does not require an entity to perform 
computer-based modeling. Topic 326 allows a quantitative or a qualitative 
adjustment to be made when assessing current conditions and reasonable and 
supportable forecasts. One way to apply a forecast on a qualitative basis is by 
using qualitative factors (Q-factors). Similar to how many entities consider 
Q-factors under existing practice in determining the allowance for credit 
losses, another approach can be used for forecasting.
If an entity's actual credit losses differ from its estimate of expected 
credit losses, is it required to modify its forecasting methodology?
The Board notes that estimates of expected credit losses often will not 
predict with precision actual future events. The objective of the amendments in 
the Update is for entities to present their best estimate of the net amount 
expected to be collected on financial assets. The amendments do not require a 
specific loss method; rather, an entity is required to use judgment in 
determining the relevant information and estimation methods that are appropriate 
in its circumstances. The Board understands that there generally is a range of 
reasonable outcomes and, therefore, expects there to be differences between 
estimates of expected credit losses and actual credit losses. Ultimately, 
estimates of future losses and actual losses should converge to the same amount. 
An entity should continue to refine future estimates of expected credit losses 
based on actual experience. For example, if actual results indicate that 
macroeconomic conditions are having a greater or lesser effect than originally 
projected, an entity may need to adjust future loss projections to reflect this 
change.
Can an entity's process for determining expected credit losses consider 
only historical information?
No. The guidance states that an entity should not rely solely on past 
events to estimate expected credit losses. When an entity uses historical loss 
information to forecast expected credit losses, it should consider the need to 
adjust historical loss information to reflect the extent to which management 
expects current conditions and reasonable and supportable forecasts to differ 
from the conditions that existed for the period over which historical loss 
information was evaluated. The adjustments, if needed, to historical loss 
information may be qualitative or quantitative in nature and should reflect 
changes related to relevant data.
 
In addition, an entity should 
consider adjustments to historical loss information for differences in current 
asset-specific risk characteristics, such as underwriting standards, portfolio 
mix, or asset term within a pool at the reporting date. An entity also should 
consider whether historical loss information used covers a sufficient time 
period such that it reflects the term of the financial asset or group of 
financial assets.
How should an entity determine which historical loss information to use 
when estimating expected credit losses?
In determining what historical loss period information best represents 
the financial assets, an entity may use historical loss information that is 
nonsequential (such as historical loss percentages based for each year since 
origination as opposed to an average 5-year historical loss percentage). The 
appropriate historical loss period can vary between loan portfolios, products, 
pools, and inputs. An entity should consider both the appropriate historical 
period and the appropriate length of the period when developing those 
estimates.
 
An entity should use judgment in determining which 
period or periods to consider when determining which historical loss information 
is most appropriate for estimating expected credit losses. An entity does not 
have to use historical losses from the most recent periods. For example, an 
entity may determine that the historical loss information that best represents 
the specific risk characteristics of the entity's current portfolio relates to 
periods from 20X2–20X5. Using the historical loss information from 20X2–20X5 as 
an input to the measurement of expected credit losses, an entity would then 
consider how current conditions and reasonable and supportable forecasts affect 
the estimate of expected credit losses. Once the historical period has been 
chosen, an entity should consider adjustments to historical loss information for 
differences in current asset specific risk characteristics, such as underwriting 
standards, portfolio mix, or asset term within a pool at the reporting date or 
when an entity's historical loss information does not reflect the contractual 
term of the financial asset or group of financial assets. For periods beyond the 
reasonable and supportable forecast period, an entity should revert to 
historical loss information that may not be from the same period used to 
estimate its reasonable and supportable forecast and should reflect the 
contractual term of the financial asset or group of financial assets. In other 
words, an entity should use historical loss information that is more reflective 
of the remaining contractual term of the financial assets for periods beyond the 
reasonable and supportable forecast period.
Is an entity required to consider all sources of available information 
when estimating expected credit losses?
No, an entity is not required to consider all sources of available 
information. Paragraph 326-20-30-7 states that "an entity is not required to 
search all possible information that is not reasonably available without undue 
cost and effort." Therefore, an entity should consider relevant information that 
is reasonably available that can be obtained without undue cost and effort. An 
entity should not ignore available information that is relevant to the estimated 
collectibility of the reported amount. This should not be interpreted to mean 
that an entity must always default to using only external data (for example, 
consensus forecasts) if its internal data is sufficient and more appropriate in 
the circumstances.
 
For example, external data may be available for 
purchase, but an entity may conclude that obtaining that information will result 
in an undue cost and to review the external information and incorporate this 
external information into the entity's processes will require too much effort, 
when internal information is sufficient in determining collectibility. 
Therefore, the entity could develop an estimate of expected credit losses on 
financial assets using internal data only.
 
Alternatively, an entity 
may have limited internal data for a particular portfolio to estimate the 
collectibility of the reported amount. Therefore, the entity will need to rely 
on external data for the purposes of developing an estimate of expected credit 
losses.
What if external data are not costly, but internal data are more relevant 
to an entity's loss calculation? Is the entity required to obtain and/or use the 
external data?
No. Certain facts and circumstances may arise for which internal data 
more appropriately capture the credit-quality risk for a specific entity than 
external data. Internal data may be more useful in estimating expected credit 
losses than external data because an entity may have captured more information 
that is unique to its business and the communities in which it operates than 
what can be captured from an external resource.
 
For example, in a 
recession, one or more portfolio segments may experience significant losses. 
While there may be publicly available data, such as volume of permits granted, 
there also may be internal data, such as profit margins which can be correlated 
to losses. Therefore, an entity may choose to rely on trends from internally 
gathered metrics, assuming the portfolio size is sufficient, on its own customer 
base rather than publicly available data in determining expected credit 
losses.
 
As another example, an entity may obtain information that 
indicates a substantial local community water contamination issue. This 
information could suggest a decline in property values, which could increase an 
entity's estimate of expected credit losses. The guidance allows an entity to 
use judgment in estimating expected credit losses, which includes the 
flexibility to decide which information should be used in estimating expected 
credit losses (internal or external data or a combination of both).
Should an entity use external data to develop estimates of credit losses 
if internal information is available?
Paragraph 326-20-30-7 states "when developing an estimate of expected 
credit losses on financial asset(s), an entity shall consider available 
information relevant to assessing the collectibility of cash flows." The 
guidance goes on to state that "information may include internal information, 
external information, or a combination of both." The guidance does not prescribe 
what type of information can be used in developing an estimate of expected 
credit losses as long as that information is relevant to the entity, which means 
that an entity can use internal information, external information, or a 
combination of both internal and external forms of information in developing an 
estimate of expected credit losses.  However, if an entity does not have 
the internal information that would be relevant to developing expected credit 
losses, it should consider external information to develop an estimate of 
expected credit losses. Similarly, an entity that has relevant internal 
information may rely on that information without acquiring or referencing 
external information. An entity is not required to search all possible 
information that is not reasonably available without undue cost and effort.
May the length of reasonable and supportable forecast periods vary 
between different portfolios, products, pools, and inputs?
Yes. The duration or length of the reasonable and supportable forecast 
period is a judgment that may vary based on the entity's ability to estimate 
economic conditions and expected losses.  The reasonable and supportable 
forecast may vary between portfolios, products, pools, and inputs. However, 
specific inputs (such as unemployment rates) should be applied on a consistent 
basis between portfolios, products, and pools, to the extent that the same 
inputs are relevant across products and pools. It also is acceptable to have a 
single reasonable and supportable period for all of an entity's products. An 
entity is to disclose information that will enable users to understand 
management's method for developing its expected credit losses, the information 
used in developing its expected credit losses, and the circumstances that caused 
changes to the expected credit losses among other disclosures about the 
allowance for credit losses.
Does an entity need to include the full contractual period (adjusted for 
prepayments) in its estimate of the reasonable and supportable forecast 
period?
No. Some entities may be able to apply reasonable and supportable 
forecasts over the estimated contractual term (that is, the contractual term 
adjusted for prepayments). However, the guidance does not require an entity to 
develop forecasts over the contractual term (adjusted for prepayments) of the 
financial asset or group of financial assets (paragraph 326-20-30-9).
 
For example, three separate lenders, each based in three different 
communities, loaned money to borrowers employed by a manufacturer that has 
operations in three separate communities. Many borrowers in each of the three 
communities are employed by one of the manufacturing plants in their community. 
The manufacturer has announced plans to close one of its manufacturing plants in 
18 months. However, it is not yet known which plant the manufacturing company 
will close. Each entity should apply judgment in developing reasonable and 
supportable forecasts when considering the effect of a possible plant closure on 
its ability to collect any principal and interest on outstanding loan balances 
from those borrowers who work at this plant. Each of the three entities may have 
different estimates of expected credit losses, including the inputs, 
assumptions, or durations for their reasonable and supportable forecast period. 
For example, entities may be able to reasonably forecast losses beyond the 
period of the plant closure or may determine that their forecasts are reasonable 
only up to the period of the plant closure.
 
Another example is when 
a wholesaler has short-term receivables from a retailer in a local mall that is 
experiencing financial difficulty. This wholesaler may be able to forecast all 
expected credit losses on the receivable, and, therefore, the reasonable and 
supportable forecast period would include the contractual term of the 
receivable.
Should an entity reevaluate its reasonable and supportable forecast 
period each reporting period?
Yes. An entity should consider the appropriateness of its reasonable and 
supportable forecast period, as well as other judgments applied in developing 
estimates of expected credit losses each reporting period. If the reasonable and 
supportable period does not cover the full expected contractual term (adjusted 
for prepayments), an entity should consider the appropriateness of the duration 
of its reversion period (that is, the periods beyond the reasonable and 
supportable period) and the methodology applied when reverting back to 
historical loss information. For example, an entity may determine that it is 
appropriate to shorten or lengthen its reasonable and supportable forecast 
period from prior periods because of changes in the uncertainty of some or all 
of the inputs and assumptions used to measure expected credit losses.
Is an entity required to correlate reasonable and supportable forecasts 
to macroeconomic data, such as nationwide or statewide data?
No. An entity is not required to correlate or reconcile reasonable and 
supportable forecasts to macroeconomic data, such as the national unemployment 
rate. Instead, when developing an estimate of expected credit losses on 
financial assets, the entity should consider available information relevant to 
assessing the collectibility of cash flows.
 
For example, a business 
closure may not correlate to any macroeconomic phenomena. Instead, an entity may 
decide to move to another state to receive a more lucrative tax treatment. In 
this instance, the macroeconomic factors may indicate a very strong job market 
with low nationwide or statewide unemployment rates, but the business closure 
may have a significant effect for the entity in the local economic environment 
when assessing the collectibility of amounts owed by its borrowers. In this 
instance, correlating a local economic event to macroeconomic data may not be 
appropriate because the macroeconomic data are not relevant.
 
In 
other instances, an entity may consider whether a national trade agreement will 
have a favorable or unfavorable effect on its ability to collect contractually 
owed cash flows from its borrowers. The entity may decide to review its internal 
information that has not indicated any changes in employment to date, but based 
on a government decision, there may be an effect on the entity's local economy 
that will result in a change to expected credit losses.
When developing a reasonable and supportable forecast to estimate 
expected credit losses, is probability weighting of multiple economic scenarios 
required?
No. Topic 326 does not require an entity to probability weight multiple 
economic scenarios when developing an estimate of expected credit losses. One 
entity may choose to probability weight multiple economic scenarios when 
developing its estimate of expected credit losses, while another entity may rely 
on a single economic scenario to develop reasonable and supportable 
forecasts.
Is there a standard threshold that can be used to adjust historical loss 
information? For example, in the most recent FASB Staff Q&A, Topic 326, No. 
1, Whether the Weighted-Average Remaining Maturity Method Is an Acceptable 
Method to Estimate Expected Credit Losses (Q&A 1), the staff assumed a 
0.25 percent qualitative adjustment to represent both current conditions and 
reasonable and supportable forecasts.
No, there is no specific standard threshold regarding adjustments for 
current conditions and reasonable and supportable forecasts. The objective of 
Topic 326 is to present an entity's estimate of the net amount expected to be 
collected on the financial asset or group of financial assets. The standard does 
not require a specific credit loss method; rather, it requires that an entity 
use judgment in determining the relevant information and estimation methods that 
are appropriate in its circumstances. This includes adjustments to historical 
loss information for current conditions and reasonable and supportable 
forecasts. The 0.25 percent adjustment used in Q&A 1 was an example of one 
way to incorporate a qualitative adjustment for both current conditions and 
reasonable and supportable forecasts. How management quantified the qualitative 
adjustment was not highlighted in the example.
What should an entity do if it cannot forecast estimated credit losses 
over the entire contractual term (adjusted for prepayments)?
An entity is not required to develop forecasts over the entire 
contractual term (adjusted for prepayments) of the financial asset or group of 
financial assets. For periods beyond which the entity is able to make or obtain 
reasonable and supportable forecasts of expected credit losses, it is required 
to revert to historical loss information that reflects expected credit losses 
during the remainder of the contractual term (adjusted for prepayments) of the 
financial asset or group of financial assets.
 
Update 2016-13 
provides entities with flexibility to determine the expected credit losses and 
does not require an entity to develop reasonable and supportable forecasts for 
the entire expected remaining life of a loan (that is, contractual term adjusted 
for prepayments), such as a 30-year mortgage. Therefore, the Board included 
guidance on how an entity should estimate expected credit losses for those 
periods beyond the reasonable and supportable forecast period. The periods after 
the reasonable and supportable forecast periods are often referred to as the 
"reversion period" and "post-reversion period," as applicable. When reverting to 
historical loss information, an entity should (1) consider whether the 
historical loss information is still relevant to estimating expected credit 
losses (that is, in accordance with paragraph 326-20-30-8, an entity may 
consider adjusting its historical loss information for differences in current 
asset-specific risk characteristics) and (2) not adjust historical loss 
information in the reversion period and post-reversion periods for existing 
economic conditions or expectations of future economic conditions.
Can an entity adjust the historical loss information used in the 
reversion period for existing economic conditions or expectations of future 
economic conditions when developing estimates of expected credit losses?
No. For periods beyond which an entity is able to make or obtain 
reasonable and supportable forecasts of expected credit losses, it should revert 
to historical loss information determined in accordance with paragraph 
326-20-30-8 that reflects expected credit losses during the remainder of the 
contractual term (adjusted for prepayments) of the financial asset or group of 
financial assets. The entity should not adjust historical loss information for 
existing economic conditions or expectations of future economic conditions for 
periods that are beyond the reasonable and supportable period.
 
The 
Board decided to require that an entity revert to historical loss information 
without adjusting historical loss information for economic conditions beyond the 
reasonable and supportable period to simplify the estimation process. However, 
this historical loss information should be adjusted for differences in current 
asset-specific risk characteristics in accordance with paragraph 326-20-30-8. 
The Board understands that an entity may need additional guidance on how to 
measure expected credit losses as it estimates losses in periods of increasing 
uncertainty and decreasing precision.  The reversion to an entity's 
historical loss information emphasizes the relevance of known loss experience 
that has occurred in the past on similar financial assets or groups of financial 
assets and addresses preparers' concerns about the reliability of estimating 
those credit losses in periods of declining precision.
Is an entity required to revert to historical loss information on a 
straight-line basis?
No. Although an entity is required to revert to historical loss 
information for periods that cannot be forecasted based on reasonable and 
supportable information, the Board did not prescribe a single methodology for 
reverting to historical loss information. Instead, the Board stated that an 
entity may revert to historical loss information immediately on a straight-line 
basis or using another rational and systematic basis. In addition, the guidance 
permits an entity to apply different reversion methods for different inputs and 
asset classes.

and addresses preparers' concerns about the reliability of estimating those 
credit losses in periods of declining precision.
 
Ultimately, an 
entity should use judgment in determining which reversion technique is most 
appropriate at the reporting date. For example, an entity identifies that a 
factory in its local economy will be closing in two years. As part of the 
entity's reasonable and supportable forecast, it considers the effect the 
closure will have on collecting its outstanding loan balances. The expected 
contractual term (adjusted for prepayments) of remaining loans exceeds the 
two-year reasonable and supportable forecast period, and, therefore, the entity 
will need to revert to historical loss information. The entity decides to apply 
a straight-line technique when reverting to historical loss information because 
the factory closing will continue to affect the collectibility of outstanding 
loan balances for periods beyond the reasonable and supportable forecast period. 
In this instance, it may not be appropriate to immediately revert to historical 
loss information because there may be a prolonged effect on the entity's ability 
to collect on contractually owed cash flows because employees of the factory may 
be unemployed for a long time. Alternatively, an entity may capture the extended 
impact of the closure in its qualitative adjustments.
 
In contrast, 
an immediate reversion methodology could be appropriate when an entity may be 
able to develop a reasonable and supportable forecast only for a market-based 
input (such as home prices) that covers one year.
 
The reversion 
method is not a policy election but rather a component of the overall estimate 
of expected credit losses. Like other components used to measure expected credit 
losses, an entity should support the reversion methodology and period it uses to 
develop its estimates of expected credit losses. Additionally, reversion to 
historical loss information, whether immediately or on a straight-line basis or 
using another reasonable methodology, is required only for periods that cannot 
be forecasted based on reasonable and supportable information.
