The decline in estimated fair value of the fixed maturity securities can be attributed primarily to changes in market interest rates and changes in credit spreads over Treasury securities. Because the Company does not have the intent to sell these securities and will likely not be compelled to sell them before it can recover its cost basis, the Company does not consider these investments to be other-than-temporarily impaired.

Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been below cost, the financial condition and prospects of the issuer (including credit ratings and analyst reports) and macro-economic changes. A total of 52 and 32 securities had unrealized losses at June 30, 2018 and December 31, 2017, respectively. Reviews of the values of securities are inherently uncertain and the value of the investment may not fully recover, or may decline in future periods resulting in a realized loss. The Company recorded no other-than-temporary impairment charges for fixed maturities for the six-month periods ended June 30, 2018 and 2017. Other-than-temporary impairment charges are included in net realized investment gains in the Consolidated Statements of Income.

Investments in Equity Securities

The estimated fair value, gross unrealized holding gains, gross unrealized holding losses and cost for equity securities are as follows:



As of June 30, 2018 (in thousands)	Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value
Equity securities, at fair value:
Common stocks	$	26,956	$	21,283	$	213	$	48,026
Total	$	26,956	$	21,283	$	213	$	48,026



As of December 31, 2017 (in thousands)	Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value
Equity securities, at fair value:
Common stocks	$	26,003	$	21,376	$	12	$	47,367
Total	$	26,003	$	21,376	$	12	$	47,367

Effective January 1, 2018, unrealized holding gains and losses are reported in the Consolidated Statements of Income as net unrealized gain or loss on equity securities. As a result, other-than-temporary impairments will no longer be considered for equity securities. The Company did not record any other-than-temporary charges for equity securities for the six-month period ended June 30, 2017.

Realized Gains from the Sale of Investment Securities

Variable Interest Entities

The Company holds investments in variable interest entities ("VIEs") that are not consolidated in the Company's financial statements as the Company is not the primary beneficiary. These entities are considered VIEs as the equity investors at risk, including the Company, do not have the power over the activities that most significantly impact the economic performance of the entities; this power resides with a third-party general partner or managing member that cannot be removed except for cause. The following table sets forth details about the Company's variable interest investments in VIEs, which are structured either as limited partnerships ("LPs") or limited liability companies ("LLCs"), as of June 30, 2018:



Type of Investment (in thousands)	Balance Sheet Classification	Carrying Value		Estimated Fair Value		Maximum Potential Loss (a)
Tax credit LPs	Other investments	$	628	$	628	$	1,325
Real estate LLCs or LPs	Other investments	4,893		5,141		7,950
Small business investment LPs	Other investments	4,142		4,261		9,400
Total		$	9,663	$	10,030	$	18,675



(a)		Maximum potential loss is calculated as the total investment in the LLC or LP, including any capital commitments that may have not yet been called. The Company is not exposed to any loss beyond the total commitment of its investment.

Valuation of Financial Assets

The FASB has established a valuation hierarchy for disclosure of the inputs used to measure estimated fair value of financial assets and liabilities, such as securities. This hierarchy categorizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value.

A financial instrument’s classification within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement – consequently, if there are multiple significant valuation inputs that are categorized in different levels of the hierarchy, the instrument’s hierarchy level is the lowest level (with Level 3 being the lowest level) within which any significant input falls.

The Level 1 category includes equity securities that are measured at estimated fair value using quoted active market prices.

The Level 2 category includes fixed maturity investments such as corporate debt securities, U.S. government and agency obligations, and municipal obligations. Estimated fair value is principally based on market values obtained from a third-party pricing service. Factors that are used in determining estimated fair market value include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. The Company receives one quote per security from a third-party pricing service, although as discussed below, the Company does consult other pricing resources when confirming that the prices it obtains reflect the fair values of the instruments in accordance with ASC 820, Fair Value Measurements and Disclosures. Generally, quotes obtained from the pricing service for instruments classified as Level 2 are not adjusted and are not binding. As of June 30, 2018 and December 31, 2017, the Company did not adjust any Level 2 fair values.

A number of the Company’s investment grade corporate debt securities are frequently traded in active markets, and trading prices are consequently available for these securities. However, these securities are classified as Level 2 because the pricing service from which the Company has obtained estimated fair values for these instruments uses valuation models that use observable market inputs in addition to trading prices. Substantially all of the input assumptions used in the service’s model are observable in the marketplace or can be derived or supported by observable market data.

In the measurement of the estimated fair value of certain financial instruments, other valuation techniques were utilized if quoted market prices were not available. These derived fair value estimates are significantly affected by the assumptions used. Additionally, ASC 820 excludes from its scope certain financial instruments, including those related to insurance contracts, pension and other postretirement benefits, and equity method investments.

In estimating the fair value of the financial instruments presented, the Company used the following methods and assumptions:

Cash and cash equivalents

The carrying amount for cash and cash equivalents is a reasonable estimate of fair value due to the short-term maturity of these investments.

Measurement alternative equity investments

The measurement alternative method requires investments without readily determinable fair values to be recorded at cost, less impairments plus or minus any changes resulting from observable price changes. The Company monitors any events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments and makes any necessary adjustments.

Accrued dividends and interest

The carrying amount for accrued dividends and interest is a reasonable estimate of fair value due to the short-term maturity of these assets.

The following table presents, by level, fixed maturities carried at estimated fair value measured as of June 30, 2018 and December 31, 2017:

The Company did not hold any Level 3 category debt or marketable equity investment securities as of June 30, 2018 or December 31, 2017.

There were no transfers into or out of Levels 1, 2 or 3 during the period.

To help ensure that estimated fair value determinations are consistent with ASC 820, prices from our pricing services go through multiple review processes to ensure appropriate pricing. Pricing procedures and inputs used to price each security include, but are not limited to, the following: unadjusted quoted market prices for identical securities such as stock market closing prices; non-binding quoted prices for identical securities in markets that are not active; interest rates; yield curves observable at commonly quoted intervals; volatility; prepayment speeds; loss severity; credit risks; and default rates. The Company reviews the procedures and inputs used by its pricing services, and verifies a sample of the services’ quotes by comparing them to values obtained from other pricing resources. In the event the Company disagrees with a price provided by its pricing services, the respective service reevaluates the price to corroborate the market information and then reviews inputs to the evaluation in light of potentially new market data. The Company believes that these processes and inputs result in appropriate classifications and estimated fair values consistent with ASC 820.

Certain equity investments under the measurement alternative are measured at estimated fair value on a non-recurring basis and are reviewed for impairment quarterly. If any such investment is determined to be other-than-temporarily impaired, an impairment charge is recorded against such investment and reflected in the Consolidated Statements of Income. There were no impairments of such investments made during the six-month period ended June 30, 2018 or the twelve-month period ended December 31, 2017. The following table presents a rollforward of equity investments under the measurement alternative as of June 30, 2018 and December 31, 2017:
