U. S. Government agency securities:
The unrealized losses on
ten
of the Company’s investments in obligations of the U. S. government were caused by increases in market interest rates over the yields available at the time the securities were purchased.  The contractual terms of those investments do
not
permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does
not
intend to sell the investments before recovery of their amortized cost basis which
may
be maturity, the Company does
not
consider those investments to be other-than-temporarily impaired at
June 30, 2017.
 
Mortgage-backed securities and CMO
’s:
The unrealized losses on
twenty-four
of the Company’s investments in government-sponsored entity mortgage-backed securities and collateralized mortgage obligations (“CMOs”) were caused by increases in market interest rates over the yields available at the time the securities were purchased. Because the decline in market value is attributable to changes in interest rates and
not
credit quality, and because the Company does
not
intend to sell the investments before recovery of their amortized cost basis, which
may
be maturity, the Company does
not
consider those investments to be other-than-temporarily impaired at
June 30, 2017.
 
Corporate securities
:
The unrealized loss on
one
of the Company’s investments in corporate securities was caused by increases in market interest rates over the yield at the time the security was purchased. Because the decline in market value is attributable to changes in interest rates and
not
credit quality, the Company does
not
consider this investment to be other-than-temporarily impaired at
June 30, 2017.
 
Municipal securities:
The unrealized losses on
eight
of the Company’s investments in municipal securities were caused by increases in market interest rates over the yields available at the time the securities were purchased. All municipal securities are investment grade. Because the decline in market value is attributable to changes in interest rates, credit spreads, and
not
credit quality, and because the Company does
not
intend to sell the investments before recovery of their amortized cost basis, which
may
be maturity, the Company does
not
consider those investments to be other-than-temporarily impaired at
June 30, 2017.
 
The following tables demonstrate the unrealized loss position of available-for-sale securities at
June 30, 2017
and
December 31, 2016.
This information summarizes the amount of time individual securities have been in a continuous, unrealized loss position.
