The establishment of an other-than-temporary impairment on an investment requires a number of judgments and estimates. The Company performs a quarterly analysis of the individual investments to determine if declines in market value are other-than-temporary. The analysis includes some or all of the following procedures as deemed appropriate by the Company: • identifying all unrealized loss positions that have existed for at least six months; • identifying other circumstances management believes may affect the recoverability of the unrealized loss positions; • obtaining a valuation analysis from third-party investment managers regarding the intrinsic value of these investments based on their knowledge and experience together with market-based valuation techniques; • reviewing the trading range of certain investments over the preceding calendar period; • assessing if declines in market value are other-than-temporary for debt instruments based on the investment grade credit ratings from third-party rating agencies; • assessing if declines in market value are other-than-temporary for any debt instrument with a non-investment grade credit rating based on the continuity of its debt service record; • determining the necessary provision for declines in market value that are considered other-than-temporary based on the analyses performed; and • assessing the Company's ability and intent to hold these investments at least until the investment impairment is recovered. The risks and uncertainties inherent in the assessment methodology used to determine declines in market value that are other-than-temporary include, but may not be limited to, the following: • the opinions of professional investment managers could be incorrect; • the past trading patterns of individual investments may not reflect future valuation trends; • the credit ratings assigned by independent credit rating agencies may be incorrect due to unforeseen or unknown facts related to a company's financial situation; and • the debt service pattern of non-investment grade instruments may not reflect future debt service capabilities and may not reflect a company's unknown underlying financial problems. As a result of the analysis performed by the Company to determine declines in market value that are other-than-temporary, there were no write-downs for other-than-temporary impairments related to investments recorded for the three and nine months ended September 30, 2018 and September 30, 2017 . The Company has reviewed currently available information regarding investments with estimated fair values less than their carrying amounts and believes these unrealized losses are not other-than-temporary and are primarily due to temporary market and sector-related factors rather than to issuer-specific factors. The Company does not intend to sell those investments, and it is not likely it will be required to sell those investments before recovery of its amortized cost. The Company does not have any exposure to subprime mortgage-backed investments. Limited liability investments include investments in limited liability companies and limited partnerships. The Company's interests in these investments are not deemed minor and, therefore, are accounted for under the equity method of accounting. The most recently available financial statements are used in applying the equity method. The difference between the end of the reporting period of the limited liability entities and that of the Company is no more than three months. As of September 30, 2018 and December 31, 2017 , the carrying value of limited liability investments totaled $6.2 million and $4.9 million , respectively. Income or loss from limited liability investments is recognized based on the Company's share of the earnings of the limited liability entities and is included in net investment (loss) income. Limited liability investment, at fair value represents the Company's investment in 15.9% of the outstanding units of 1347 Investors LLC ("1347 Investors"). The Company has made an irrevocable election to account for this investment at fair value. As of September 30, 2018 and December 31, 2017 , the carrying value of the Company's limited liability investment, at fair value was $4.5 million and $5.8 million , respectively. Other investments include collateral loans and are reported at their unpaid principal balance. As of September 30, 2018 and December 31, 2017 , the carrying value of other investments totaled $1.9 million and $2.3 million , respectively. The Company had previously entered into two separate performance share grant agreements with 1347 Property Insurance Holdings, Inc. ("PIH"), whereby the Company will be entitled to receive up to an aggregate of 475,000 shares of PIH common stock upon achievement of certain milestones for PIH’s stock price. Pursuant to the performance share grant agreements, if at any time the last sales price of PIH’s common stock equals or exceeds: (i) $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period, the Company will receive 100,000 shares of PIH common stock; (ii) $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period, the Company will receive 125,000 shares of PIH common stock (in addition to the 100,000 shares of common stock earned pursuant to clause (i) herein); (iii) $15.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period, the Company will receive 125,000 shares of PIH common stock (in addition to the 225,000 shares of common stock earned pursuant to clauses (i) and (ii) herein); and (iv) $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period, the Company will receive 125,000 shares of PIH common stock (in addition to the 350,000 shares of common stock earned pursuant to clauses (i), (ii) and (iii) herein). To the extent shares of PIH common stock are granted to the Company under either of the performance share grant agreements, they will be recorded at the time the shares are granted and will have a valuation equal to the last sales price of PIH common stock on the day prior to such grant. During the first quarter of 2018, the Company entered into an agreement with PIH to cancel the $10.00 per share performance shares grant agreement in exchange for cash consideration of $0.3 million . During the third quarter of 2018, the Company entered into an agreement with PIH to cancel the $12.00 per share, $15.00 per share and $18.00 per share performance share grant agreement in exchange for cash consideration of $1.0 million . For the three and nine months ended September 30, 2018 , the Company recorded a gain, included in gain on change in fair value of equity investments in the consolidated statements of operations, of $1.0 million and $1.3 million , respectively, related to these transactions. No shares were received by the Company under either of the performance share grant agreements as of September 30, 2018 .
