As of

March 31, 2018,

the Company had unrealized losses on available-for-sale securities of

$31.7

million. The unrealized losses on these securities were primarily attributed to yield curve movement, together with widened liquidity spreads and credit spreads. The issuers have

not,

to the Company’s knowledge, established any cause for default on these securities. Management believes the impairment was temporary and, accordingly,

impairment loss on these securities has been recognized in our condensed consolidated statements of operations. The Company expects to recover the amortized cost basis of its securities and has

intent to sell, and will

not

be required to sell, available-for-sale securities that have declined below their cost before their anticipated recovery.

Investment securities having a carrying value of

$231.0

million as of

March 31, 2018,

and

$272.2

million as of

December 31, 2017,

were pledged to secure public deposits, other borrowings, treasury tax and loan, and securities sold under agreements to repurchase.
