funds, the Trust unitholders will not receive distributions until the borrowed funds together with any accumulated net losses and accrued interest are repaid. The Trust does not have any transactions, arrangements or other relationships with unconsolidated entities or persons that could materially affect the Trust’s liquidity or the availability of capital resources. As of July 31, 2021, the Trust had cash reserves of $0.2 million remaining for the payment of its administrative expenses.
The Trust is highly dependent on Whiting for multiple services, including the operation of wells, remittance of net proceeds generated by the NPI and administrative services performed on behalf of the Trust. Whiting’s continued ability to operate wells, including those with interests held by the NPI, depends on its future financial condition, access to capital and other factors outside of its control. On April 1, 2020, Whiting and certain of its direct and indirect subsidiaries, including Whiting Oil and Gas (collectively, the “Debtors”) commenced voluntary cases under chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”). On June 30, 2020, the Debtors filed the Joint Chapter 11 Plan of Reorganization of Whiting Petroleum Corporation and its Debtor affiliates (as amended, modified and supplemented, the “Plan”). On August 14, 2020, the Bankruptcy Court confirmed the Plan. On September 1, 2020, the Debtors emerged from the Chapter 11 Cases and the Plan became effective in accordance with its terms.
Letter of credit. In June 2012, Whiting established a $1.0 million letter of credit for the Trustee in order to provide a mechanism for the Trustee to pay the operating expenses of the Trust in the event that Whiting should fail to lend funds to the Trust, if requested to do so by the Trustee. This letter of credit will not be used to fund NPI distributions to unitholders, and if the Trustee were to draw on the letter of credit or were to borrow funds from Whiting or other entities, no further distributions would be made to unitholders until all such amounts have been repaid by the Trust. Such letter of credit will expire December 31, 2021. As of June 30, 2021 and December 31, 2020, the Trust had no borrowings under the letter of credit.
Reserve for expenditures. As provided in the terms of the NPI, Whiting established a reserve for expenditures of $1.6 million during the six months ended June 30, 2020 for future development, maintenance or operating expenses. Such reserve was subsequently utilized and applied against qualifying expenses incurred during the remainder of 2020. Accordingly, there is no remaining reserve for expenditures to offset future development, maintenance or operating expenses on the underlying properties and related activities. No such reserve was established during the six months ended June 30, 2021.
Plugging and abandonment. Plugging and abandonment costs related to the underlying properties, net of any proceeds received from the salvage of equipment, cannot be included as a deduction in the calculation of net proceeds pursuant to the terms of the conveyance agreement. During the three and six months ended June 30, 2021, Whiting incurred $0.1 million and $0.3 million, respectively, of plugging and abandonment charges on the underlying properties, and these costs were not charged to the unitholders of the Trust.
Future Trust Payment Periods
On August 5, 2021, the Trustee announced the Trust’s distribution of net profits for the second quarterly payment period in 2021. Unitholders of record on August 19, 2021 are expected to receive a distribution of $0.180407 per Trust unit, which is payable on or before August 27, 2021. This aggregate distribution to all Trust unitholders is expected to consist of net cash proceeds of $4.6 million paid by Whiting to the Trust, less a provision of $1.3 million for estimated Trust expenses and $5,949 for Montana state income tax withholdings.
Although oil and gas prices have improved since the lows experienced during 2020, oil and gas prices have historically been volatile and may fluctuate widely in the future. The Trust is unable to predict future commodity prices or future performance and distributions to unitholders are significantly impacted by low oil and natural gas prices and may be reduced to zero, as was the case during the second, third and fourth quarters of 2020 and first quarter of 2021. Additionally, in the current commodity price environment, the Trust’s distributions have increased sensitivity to fluctuations in operating and capital expenditures and commodity price differentials. If the NPI generates net losses or limited net proceeds, the net profits interest may not provide sufficient funds to the Trustee to enable it to pay all of the Trust’s administrative expenses, which expenses may be in excess of the provision for Trust expenses.
Critical Accounting Policies and Estimates
A disclosure of critical accounting policies and the more significant judgments and estimates used in the preparation of the Trust’s financial statements is included in Item 7 of the Trust’s Annual Report on Form 10-K for the year ended December 31, 2020. There have been no significant changes to the critical accounting policies during the six months ended June 30, 2021.
