Related Party Transactions [Abstract]
Related Party Transactions	See the description of the Merger Agreement between the Company and JHC in Note 10, pursuant to which the Company acquired JHC in the Merger and JHC became a wholly-owned subsidiary of the Company on October 1, 2018. Before completion of the Merger, the Company’s portfolio of aircraft assets was managed and administered under the terms of a management agreement with JMC (the “Management Agreement”). Certain officers of the Company were also officers of JHC and JMC and held significant ownership positions in both JHC and the Company, and JHC was also a significant stockholder of AeroCentury. Under the Management Agreement, JMC received a monthly management fee based on the net asset value of the Company’s assets under management. JMC also received an acquisition fee for locating assets for the Company. Acquisition fees were included in the cost basis of the asset purchased. JMC also received a remarketing fee in connection with the re-lease or sale of the Company’s assets. Remarketing fees were amortized over the applicable lease term or included in the gain or loss on sale. In April 2018, subsequent to the execution of the Merger Agreement for the acquisition of JHC, JHC agreed to waive its right to receive management and acquisition fees (“Contract Fees”) otherwise owed by the Company to JHC pursuant to the Management Agreement for all periods after March 31, 2018 and until the earlier of the consummation of the Merger or August 15, 2018. In return, the Company agreed to reimburse JMC for expenses (“Management Expense”) incurred in providing management services set forth under the Management Agreement. In July 2018, JHC agreed to extend the expiration of this agreement (the “Waiver and Reimbursement Agreement”) through October 15, 2018. Thus, if the Merger Agreement was terminated on or before October 15, 2018 or the Merger did not close by October 15, 2018, the Company would have become obligated to pay JMC any excess (the “JMC Margin”) of (i) the Contract Fees that would have been paid to JMC since April 1, 2018 in the absence of the Waiver and Reimbursement Agreement over (ii) the Management Expenses actually paid by the Company to JMC since April 1, 2018. For the nine months ended September 30, 2018, Contract Fees exceeded the reimbursed Management Expense by $1,023,000 of management fees and $494,000 of acquisition fees. Notwithstanding the Waiver and Reimbursement Agreement, until the closing or termination of the Merger Agreement, the Company accrued as an expense the total Contract Fees that would have been due under the Management Agreement. Because the Merger closed on October 1, 2018, the Waiver and Reimbursement Agreement for the period from April 1, 2018 through September 30, 2018 was considered in the acquisition accounting for the calculation of the settlement loss recognized by the Company when the Merger was consummated. The Company incurred management fees and acquisition fees of $4,482,800 and $494,400, respectively, during 2018.
