- Fair Value Measurement
 
 
FASB ASC
820,
“Fair Value Measurement” establishes a fair value hierarchy based on the nature of data inputs for fair value determinations, under which the Corporation is required to value each asset using assumptions that market participants would utilize to value that asset. When the Corporation uses its own assumptions it is required to disclose additional information about the assumptions used and the effect of the measurement on earnings or the net change in assets for the period.
 
The value of the Corporation’s available for sale investment securities, which include obligations of the U.S. government and its agencies, mortgage-backed securities issued by U.S. government- and U.S. government sponsored agencies, obligations of state and political subdivisions, corporate bonds, other debt securities, as well as bond mutual funds are determined by the Corporation, including the use of an independent
third
party. The Corporation performs tests to assess the validity of these
third
-party values. The
third
party’s evaluations are based on market data. They utilize pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their pricing models apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads,
two
-sided markets, benchmark securities, bid, offers and reference data. For certain securities, additional inputs
may
be used or some market inputs
may
not be applicable. Inputs are prioritized differently on any given day based on market conditions.
 
U.S. Government agencies are evaluated and priced using multi-dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage-backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other available-for-sale investments are evaluated using a broker-quote based application, including quotes from issuers.
 
The value of the investment portfolio is determined using
three
broad levels of inputs:
 
Level
1
– Quoted prices in active markets for identical securities.
 
Level
2
– Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active and model derived valuations whose inputs are observable or whose significant value drivers are observable.
 
Level
3
– Instruments whose significant value drivers are unobservable.
 
These levels are not necessarily an indication of the risks or liquidity associated with these investments. The following tables summarize the assets at
December
31,
2016
and
2015
that are recognized on the Corporation’s balance sheet using fair value measurement determined based on the differing levels of input.
