(

) Assets and Liabilities Measured and Reported at Fair Value
 
Bancorp follows provisions of authoritative guidance for fair value measurements. This guidance is definitional and disclosure oriented and addresses how companies should approach measuring fair value when required by US GAAP. The guidance also prescribes various disclosures about financial statement categories and amounts which are measured at fair value, if such disclosures are
not
already specified elsewhere in US GAAP.
 
A
uthoritative guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between participants at the measurement date. The guidance also establishes a hierarchy to group assets and liabilities carried at fair value in
three
levels based upon markets in which the assets and liabilities trade and reliability of assumptions used to determine fair value.
 
These levels are:
 
 
Level
1
: Valuation is based upon quoted prices for identical instruments traded in active markets.
 
Level
2
: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are
not
active, and model-based valuation techniques for which all significant assumptions are observable in the market.
 
Level
3
: Valuation is generated from model-based techniques that use significant assumptions
not
observable in the market. These unobservable assumptions would reflect our own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques could include pricing models, discounted cash flows and other similar techniques.
 
Authoritative guidance requires maximization of use of observable inputs and minimization of use of unobservable inputs in fair value measurements. Where there exists limited or
no
observable market data, Bancorp derives its own estimates by generally considering characteristics of the asset/liability, the current economic and competitive environment and other factors. For this reason, results cannot be determined with precision and
may
not
be realized on an actual sale or immediate settlement of the asset or liability.
 
Bancorp
’s investment securities available-for-sale and interest rate swaps are recorded at fair value on a recurring basis. Other accounts including mortgage servicing rights, impaired loans and other real estate owned
may
be recorded at fair value on a non-recurring basis, generally in the application of lower of cost or market adjustments or write-downs of specific assets.
 
The portfolio of investment securities available-for-sale is comprised of U.S. Treasury and other U.S. government obligations, debt securities of U.S. government-sponsored corporations (including mortgage-backed securities), obligations of state and political subdivisions and corporate equity securities. U.S. Treasury and corporate equity securities are priced using quoted prices of identical securities in an active market. These measurements are classified as Level
1
in the hierarchy above. All other securities are priced using standard industry models or matrices with various assumptions such as yield curves, volatility, prepayment speeds, default rates, time value, credit rating and market prices for similar instruments. These assumptions are observable in the market place and can be derived from or supported by observable data. These measurements are classified as Level
2
in the hierarchy above.
 
Interest rate swaps are valued using primarily Level
2
inputs. Fair value measurements
are based on benchmark forward yield curves and other relevant observable market data. For purposes of potential valuation adjustments to derivative positions, Bancorp evaluates the credit risk of its counterparties as well as its own credit risk. To date, Bancorp has
not
realized any losses due to counterparty’s inability to perform and the change in value of derivative assets and liabilities attributable to credit risk was
not
significant during
2017.

Bancorp
had
no
financial instruments classified within Level
3
of the valuation hierarchy for assets and liabilities measured at fair value on a recurring basis at
December 31, 2017
or
2016.
 
MSRs are recorded at fair value upon capitalization, are amortized to correspond with estimated servicing income, and are periodically assessed for impairment based on fair value at the reporting date. Fair value is based on a valuation
model that calculates the present value of estimated net servicing income. The model incorporates assumptions that market participants would use in estimating future net servicing income. These measurements are classified as Level
3.
At
December 31, 2017
and
2016
there was
no
valuation allowance for mortgage servicing rights, as fair value exceeded cost. Accordingly, MSRs are
not
included in either table below for
December 31, 2017
or
2016.
See Note
7
for more information regarding MSRs.
 
For impaired loans in the table below, fair value is calculated
carrying value of loans with a specific valuation allowance, less the specific allowance, and the carrying value of collateral dependent loans that have been charged down to their fair value. Fair value of impaired loans was primarily measured based on the value of collateral securing these loans. Impaired loans are classified within Level
3
of the fair value hierarchy. Collateral
may
be real estate and/or business assets including equipment, inventory, and/or accounts receivable. Bancorp determines the value of the collateral based on independent appraisals performed by qualified licensed appraisers. These appraisals
may
utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised values are discounted for costs to sell and
may
be discounted further based on management’s historical knowledge, changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts by management are subjective and are typically significant unobservable inputs for determining fair value. As of
December 31, 2017,
total impaired collateral dependent loans charged down to their fair value and impaired loans with a valuation allowance were
$2.6
million, and the specific allowance totaled
$48
thousand, resulting in a fair value of
$2.6
million, compared with total collateral dependent loans charged down to their fair value and impaired loans with a valuation allowance of
$4.2
million, and the specific allowance allocation totaling
$1.3
million, resulting in a fair value of
$2.9
million at
December 31, 2016.
Losses represent charge offs and changes in specific allowances for the period indicated.
 
Other real estate owned (
“OREO”), which is carried at the lower of cost or fair value, is periodically assessed for impairment based on fair value at the reporting date. Fair value is based on appraisals performed by external parties which use judgments and assumptions that are property-specific and sensitive to changes in the overall economic environment. Appraisals
may
be further discounted based on management’s historical knowledge and/or changes in market conditions from the date of the most recent appraisal. Many of these inputs are
not
observable and, accordingly, these measurements are classified as Level
3.
For OREO in the table below, fair value is the carrying value of only parcels of OREO which have a carrying value equal to appraised value. Losses represent write-downs which occurred during the period indicated. At
December 31, 2017
and
2016,
carrying value of all other real estate owned was
$2.6
million and
$5.0
million, respectively.

In the case of the securities portfolio, Bancorp monitors the valuation technique utilized by pricing agencies to ascertain when transfers between levels have occurred. The nature of the remaining assets and liabilities is such that transfers in and out of any level are expected to be rare. For the
years ended
December 31, 2017,
2016
and
2015,
there were
no
transfers between Levels
1,
2,
or
3.
