Securities and Equity Investments

At September 30, 2017, and 2016, we held an investment in EnerTech Capital Partners II L.P. (“EnerTech”), a private investment fund. As our investment was 2.21% of the overall ownership in EnerTech at September 30, 2017, and 2016, we account for this investment using the cost method of accounting. EnerTech’s investment portfolio from time to time results in unrealized losses reflecting a possible, other-than-temporary, impairment of our investment. During the year ended September 30, 2017, we collected a distribution of $361, reducing the carrying value of our investment. The carrying value of our investment in EnerTech at September 30, 2017, and 2016 was $558, and $919, respectively.

The following table presents the reconciliation of the carrying value and unrealized gains (losses) to the fair value of the investment in EnerTech as of September 30, 2017, and 2016:

	Years Ended September 30,
	2017		2016
Carrying value	$	558	$	919
Unrealized gains		171		159
Fair value	$	729	$	1,078

At each reporting date, the Company performs an evaluation of impairment for securities to determine if any unrealized losses are other-than-temporary. For equity securities, this evaluation considers a number of factors including, but not limited to, the length of time and extent to which the fair value has been less than cost, the financial condition and near term prospects of the issuer and management’s ability and intent to hold the securities until fair value recovers. The assessment of the ability and intent to hold these securities to recovery focuses on liquidity needs, asset and liability management objectives and securities portfolio objectives. Based on the results of this evaluation, we believe the unrealized gain at September 30, 2017 indicated our investment was not impaired.

In December 2016, EnerTech’s general partner, with the consent of the fund’s investors, extended the fund through December 31, 2017. The fund is expected to terminate on this date unless extended by the fund’s valuation committee. The fund may be extended for another one-year period through December 31, 2018, with the consent of the fund’s valuation committee.
