Restricted Stock

Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank of Richmond ("FRB") and Federal Home Loan Bank of Atlanta ("FHLB"), these securities have been classified as restricted equity securities and carried at cost. The restricted securities are not subject to the investment security classification and are included as a separate line item on the Company's Consolidated Balance Sheet. The FRB requires the Bank to maintain stock with a par value equal to 3.0% of its outstanding capital and an additional 3.0% is on call. The FHLB requires the Bank to maintain stock in an amount equal to 4.5% of outstanding borrowings and a specific percentage of the Bank's total assets. The cost of restricted stock at June 30, 2016 and December 31, 2015 was as follows (dollars in thousands):



	June 30, 2016		December 31, 2015
FRB stock	$	3,547	$	3,535
FHLB stock	1,815		1,777
Total restricted stock	$	5,362	$	5,312

Temporarily Impaired Securities

The following table shows estimated fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at June 30, 2016. The reference point for determining when securities are in an unrealized loss position is month-end. Therefore, it is possible that a security's market value exceeded its amortized cost on other days during the past twelve-month period.

Available for sale securities that have been in a continuous unrealized loss position are as follows (dollars in thousands):



	Total				Less than 12 Months				12 Months or More
	Fair Value		Unrealized Loss		Fair Value		Unrealized Loss		Fair Value		Unrealized Loss
Federal agencies and GSEs	$	8,505	$	1	$	8,505	$	1	$	—	$	—
Mortgage-backed and CMOs	2,589		19		648		1		1,941		18

GSE debt securities: The unrealized loss on the Company's investment in two government sponsored entity ("GSE") securities was caused by interest rate increases. 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 and it is not more likely than not that the Company will be required 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, 2016.

Mortgage-backed securities and CMOs: The unrealized losses on the Company's investment in six GSE mortgage-backed securities and collateralized mortgage obligations ("CMOs") were caused by interest rate increases. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost basis of the Company's investments. 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 and it is not more likely than not that the Company will be required 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, 2016.

State and municipal securities: The unrealized losses on seven state and municipal securities were caused by interest rate increases. 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 and it is not more likely than not that the Company will be required 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, 2016.

Corporate securities: The Company had zero investments with unrealized losses in corporate securities. In prior periods when unrealized losses were shown they were caused by interest rate increases. The contractual terms of those investments did not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company did not intend to sell the investments and it was not more likely than not that the Company would be required to sell the investments before recovery of their amortized cost basis, which may have been maturity, the Company did not consider those investments to be other-than-temporarily impaired at June 30, 2016.

Restricted stock: When evaluating restricted stock for impairment, its value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The Company does not consider restricted stock to be other-than-temporarily impaired at June 30, 2016, and no impairment has been recognized.
