Significant Accounting Policies [Text Block]	2.

Under this method of accounting, SHG was treated as the acquired company for financial reporting purposes, and Sky was treated as the accounting acquirer. In accordance with this accounting method, the Yellowstone Transaction was treated as the equivalent of Sky issuing stock for the net assets of Yellowstone, accompanied by a recapitalization. Sky was deemed the accounting acquirer for purposes of the Yellowstone Transaction based on an evaluation of the following facts and circumstances: • The LLC Interests, through their ownership of the Class B Common Stock, hold a majority voting interest in the Company; • The LLC Interests have the ability to nominate and elect the majority of the Company’s Board of Directors; • Sky’s senior management team comprises the senior management of the Company; and • Sky’s assets were larger in relative size compared to Yellowstone’s assets prior to the Yellowstone Transaction. Thus, the financial statements included in this quarterly report for the three March 31, 2022 no Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include the estimates of collectability of tenant lease payments, assumptions used within impairment analyses, estimated useful lives of depreciable assets and amortizable costs, estimates of inputs utilized in determining incentive compensation expense and financial instruments such as warrants, and estimates and assumptions related to right-of-use assets and operating lease liabilities. Actual results could differ materially from those estimates. Risks and Uncertainties The Company’s operations have been limited to-date. For most of its history, the Company was engaged in securing access to land through ground leases, and developing and constructing aviation hangars. The major risks faced by the Company is its future ability to obtain additional tenants for the facilities that it constructs, and to contract with such tenants for rental income in an amount that is sufficient to meet the Company’s financial obligations, including increasing construction costs.

The cost of acquiring an asset includes the costs necessary to bring a capital project to the condition necessary for its intended use. Costs are capitalized once the construction of a specific capital project is probable. Construction labor and other direct costs of construction are capitalized. Professional fees for engineering, procurement, consulting, and other soft costs that are directly identifiable with the project and are considered an incremental direct cost are capitalized. The Company allocates a portion of its internal salaries to both capitalized cost of construction and to general and administrative expense based on the percentage of time certain employees worked in the related areas. Interest, net of the amortization of debt issuance costs and premiums, and net of interest income earned on bond proceeds, is also capitalized until the capital project is completed. Constructed assets, net Constructed assets on the consolidated balance sheets consists principally of developed airplane hangar buildings, and are carried at cost less accumulated depreciation.

Under this method of accounting, SHG was treated as the acquired company for financial reporting purposes, and Sky was treated as the accounting acquirer. In accordance with this accounting method, the Yellowstone Transaction was treated as the equivalent of Sky issuing stock for the net assets of Yellowstone, accompanied by a recapitalization. Sky was deemed the accounting acquirer for purposes of the Yellowstone Transaction based on an evaluation of the following facts and circumstances: • The LLC Interests, through their ownership of the Class B Common Stock, hold a majority voting interest in the Company; • The LLC Interests have the ability to nominate and elect the majority of the Company’s Board of Directors; • Sky’s senior management team comprises the senior management of the Company; and • Sky’s assets were larger in relative size compared to Yellowstone’s assets prior to the Yellowstone Transaction. Thus, the financial statements included in this quarterly report for the three March 31, 2022 no Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include the estimates of collectability of tenant lease payments, assumptions used within impairment analyses, estimated useful lives of depreciable assets and amortizable costs, estimates of inputs utilized in determining incentive compensation expense and financial instruments such as warrants, and estimates and assumptions related to right-of-use assets and operating lease liabilities. Actual results could differ materially from those estimates. Risks and Uncertainties The Company’s operations have been limited to-date. For most of its history, the Company was engaged in securing access to land through ground leases, and developing and constructing aviation hangars. The major risks faced by the Company is its future ability to obtain additional tenants for the facilities that it constructs, and to contract with such tenants for rental income in an amount that is sufficient to meet the Company’s financial obligations, including increasing construction costs.

The Company allocates a portion of its internal salaries to both capitalized cost of construction and to general and administrative expense based on the percentage of time certain employees worked in the related areas.
