See below for further details regarding our note receivable related to four affiliates of Técnicas Maritimas Avanzadas, S.A. de C.V. (collectively, “TMA”). Net investment in notes receivable consisted of the following: March 31, 2018 December 31, 2017 Principal outstanding (1) $ 9,045,850 $ 10,119,672 Deferred fees (289,575 ) (313,120 ) Credit loss reserve (2) — (1,550,490 ) Net investment in notes receivable (3) $ 8,756,275 $ 8,256,062 (1) As of March 31, 2018 and December 31, 2017 , total principal outstanding related to our impaired loan was $2,500,000 and $3,500,490 , respectively. (2) As of December 31, 2017 , we had a credit loss reserve of $2,615,158 related to TMA, of which $1,064,668 was reserved against the accrued interest receivable included in other assets and $1,550,490 was reserved against net investment in notes receivable. (3) As of March 31, 2018 and December 31, 2017 , net investment in notes receivable related to our impaired loan was $2,500,000 and $1,950,000 , respectively. On July 14, 2014, we, ICON Leasing Fund Twelve Liquidating Trust (formerly, ICON Leasing Fund Twelve, LLC) (“Fund Twelve”) and ICON ECI Fund Fifteen, L.P. (“Fund Fifteen”), each an entity also managed by our Investment Manager (collectively, “ICON”), entered into a secured term loan credit facility agreement with TMA to provide a credit facility of up to $29,000,000 (the “ICON Loan”), of which our commitment of $ 3,625,000 was funded on August 27, 2014 (the “TMA Initial Closing Date”). The facility was used by TMA to acquire and refinance two platform supply vessels. At inception, the loan bore interest at the London Interbank Offered Rate (“LIBOR”), subject to a 1% floor, plus a margin of 17% . Upon the acceptance of both vessels by TMA’s sub-charterer on September 19, 2014, the margin was reduced to 13% . On November 24, 2014, ICON entered into an amended and restated senior secured term loan credit facility agreement with TMA pursuant to which an unaffiliated third-party (the “Senior Lender”) agreed to provide a senior secured term loan in the amount of up to $89,000,000 (the “Senior Loan,” and collectively with the ICON Loan, the “TMA Facility”) to acquire two additional vessels. The TMA Facility has a term of five years from the TMA Initial Closing Date. As a result of the amendment, the margin for the ICON Loan increased to 15% and repayment of the ICON Loan became subordinated to the repayment of the Senior Loan. The TMA Facility is secured by, among other things, a first priority security interest in the four vessels and TMA’s right to the collection of hire with respect to earnings from the sub-charterer related to the four vessels. As a condition to the amendment and increased size of the TMA Facility, TMA was required to cause all four platform supply vessels to be under contract by March 31, 2015. Due to TMA’s failure to meet such condition, TMA was in technical default and in payment default while available cash was swept by the Senior Lender and applied to the Senior Loan in accordance with the loan agreement. As a result, the principal balance of the Senior Loan amortized at a faster rate. In January 2016, the remaining two previously unchartered vessels had commenced employment. Our Investment Manager continued to assess the collectability of the note receivable at each reporting date as TMA’s credit quality slowly deteriorated and the fair market value of the collateral continued to decrease. During the three months ended June 30, 2017, our Investment Manager believed it was prudent to place the note receivable on non-accrual status. In September 2017, our Investment Manager met with certain restructuring advisors engaged by TMA to discuss a potential restructuring of the company. In light of these developments and a decrease in the fair market value of the collateral, in which we have a second priority security interest, our Investment Manager determined to record a credit loss of $1,750,000 during the three months ended September 30, 2017. On December 26, 2017, ICON, the Senior Lender and TMA entered into a restructuring support and lock-up agreement to commit to a restructuring of TMA’s outstanding debt obligations and to provide additional funding to TMA, subject to execution of definitive agreements. As a result of this restructuring (as further described below), our Investment Manager assessed the collectability of the note receivable as of December 31, 2017 and recorded an additional credit loss of $865,158 for the three months ended December 31, 2017. On January 5, 2018, ICON, the Senior Lender and TMA executed all definitive agreements including, without limitation, the second amended and restated term loan credit facility agreement in connection with the restructuring of the TMA Facility (the “Second Amendment”). Under the Second Amendment, ICON funded a total of $8,000,000 in exchange for (i) all amounts payable under the Senior Loan will amortize at a faster rate, at which time ICON will become the senior lender and have a first priority security interest in the four vessels and TMA’s right to the earnings generated by the vessels; and (ii) a 12.5% equity interest in two affiliates of TMA. Also as part of the Second Amendment, ICON agreed to reduce its aggregate notes and interest receivables to $20,000,000 in connection with the overall restructuring plan. As a result of the Second Amendment, on January 5, 2018, we funded our additional commitment of $1,000,000 , which represented our share of the total additional commitment to TMA, and our note and interest receivables due from TMA were reduced to $2,500,000 . As of January 5, 2018, our share of the fair value of the 12.5% equity interest in two affiliates of TMA was estimated to be $450,000 , which was based on an independent third-party valuation. Of our $1,000,000 additional commitment to TMA, we recorded $450,000 as an investment accounted for under the equity method of accounting (see Note 6) and the remaining $550,000 as an additional loan to TMA. As a result of this restructuring, during the three months ended March 31, 2018, we wrote off the allowance for credit loss of $2,615,158 related to TMA, of which $1,064,668 was previously reserved against the accrued interest receivable and $1,550,490 was previously reserved against our net investment in notes receivable. In addition, we also wrote off the corresponding $1,064,668 accrued interest receivable. In accordance with the Second Amendment, our restructured loan of $ 2,500,000 bears interest at a rate of 12% per year and is scheduled to mature on January 5, 2021 . Interest will accrue as paid-in-kind interest until such time as the Senior Loan is satisfied in full, which we expect to occur during 2018 . Upon satisfaction of the Senior Loan, our loan will amortize at 25% per year and interest will be paid in cash, both payable quarterly in arrears. The amended TMA Facility is secured by substantially the same collateral that secured the TMA Facility prior to the restructuring. As of March 31, 2018 and December 31, 2017, our share of the collateral value, net of the balance of the Senior Loan, was estimated to be approximately $3,750,000 and $2,250,000 , respectively. As of March 31, 2018 and December 31, 2017, our net investment in notes receivable related to TMA was $2,500,000 and $1,950,000 , respectively. In addition, as of December 31, 2017, we have an accrued interest receivable related to TMA of $1,064,668 , which has been fully reserved, resulting in a net carrying value of $0 . During the three months ended March 31, 2018 and 2017, we recognized finance income of $70,833 and $111,279 , respectively, of which no amount was recognized on a cash basis. Credit loss allowance activities for the three months ended March 31, 2018 were as follows: Credit Loss Allowance Allowance for credit loss as of December 31, 2017 $ 2,615,158 Provisions — Write-offs, net of recoveries (2,615,158 ) Allowance for credit loss as of March 31, 2018 $ — Credit loss allowance activities for the three months ended March 31, 2017 were as follows: Credit Loss Allowance Allowance for credit loss as of December 31, 2016 $ 33,393,546 Provisions — Write-offs, net of recoveries — Allowance for credit loss as of March 31, 2017 $ 33,393,546 |
