The balances required to be held in these margin accounts increase as the net value of the outstanding energy-related contracts with the respective counterparties decrease. As of March 31, 2018 and December 31, 2017, SJI's balances (including SJG) in these accounts totaled $16.4 million and $31.6 million, respectively, held by the counterparty, which is recorded in Restricted Investments on the condensed consolidated balance sheets. As of March 31, 2018 and December 31, 2017, SJG's balance held by the counterparty totaled $2.3 million and $2.9 million and was recorded in Restricted Investments on the condensed balance sheets.

The carrying amounts of the Restricted Investments for both SJI and SJG approximate their fair values at March 31, 2018 and December 31, 2017, which would be included in Level 1 of the fair value hierarchy (see Note 13).

NOTES RECEIVABLE-AFFILIATES - As of March 31, 2018, SJI had approximately $13.6 million included in Notes Receivable - Affiliate on the condensed consolidated balance sheets, due from Energenic, which is secured by its cogeneration assets for energy service projects. This note is subject to a reimbursement agreement that secures reimbursement for SJI, from its joint venture partner, of a proportionate share of any amounts that are not repaid.

LONG-TERM RECEIVABLES - SJG provides financing to customers for the purpose of attracting conversions to natural gas heating systems from competing fuel sources. The terms of these loans call for customers to make monthly payments over periods ranging from five to ten years, with no interest. The carrying amounts of such loans were $6.6 million and $7.0 million as of March 31, 2018 and December 31, 2017, respectively. The current portion of these receivables is reflected in Accounts Receivable and the non-current portion is reflected in Contract Receivables on the condensed consolidated balance sheets. The carrying amounts noted above are net of unamortized discounts resulting from imputed interest in the amount of $0.7 million as of both March 31, 2018 and December 31, 2017. The annualized amortization to interest is not material to SJI’s or SJG's condensed consolidated financial statements. The carrying amounts of these receivables approximate their fair value at March 31, 2018 and December 31, 2017, which would be included in Level 2 of the fair value hierarchy (see Note 13).

CREDIT RISK - As of March 31, 2018, SJI had approximately $4.3 million, or 11.9%, of the current and noncurrent Derivatives – Energy Related Assets transacted with one counterparty. This counterparty has contracts with a large number of diverse customers which minimizes the concentration of this risk. A portion of these contracts may be assigned to SJI in the event of default by the counterparty.

FINANCIAL INSTRUMENTS NOT CARRIED AT FAIR VALUE - The fair value of a financial instrument is the market price to sell an asset or transfer a liability at the measurement date.
