Mr. Moroney also acts as Landmark-Pegasus’ President.
Basis of Presentation	Basis of Presentation The interim unaudited condensed financial statements included herein have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of the Company’s management, all adjustments (consisting of normal recurring adjustments and reclassifications and non-recurring adjustments) necessary to present fairly the results of operations and cash flows for the three and six months ended March 31, 2019, and the financial position as of March 31, 2019, have been made. The results of operations for such interim periods are not necessarily indicative of the operating results to be expected for the full year. Certain information and disclosures normally included in the notes to the annual financial statements have been condensed or omitted from these interim condensed financial statements. Accordingly, these interim condensed financial statements should be read in conjunction with the Audited Financial Statements and Notes thereto as of and for the year ended September 30, 2018 included in our Report on Form 10-K as filed with the SEC on December 26, 2018. The September 30, 2018 balance sheet is derived from those financial statements.
Use of Estimates	Use of Estimates The financial statements are prepared in accordance with Accounting Principles Generally Accepted in the United States (“GAAP”). These accounting principles require the Company to make certain estimates, judgments and assumptions. The Company believes that the estimates, judgments and assumptions upon which it relies are reasonable based upon information available at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. The financial statements would be affected to the extent there are material differences between these estimates and actual results. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. Significant estimates include the valuation allowance on deferred tax assets.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers financial instruments with original maturities of three months or less to be cash equivalents. The Company had no cash equivalents at September 30, 2018 or March 31, 2019.
Revenue Recognition	Revenue Recognition On August 12, 2015, the FASB issued an Accounting Standards Update (“ASU”), Revenue From Contracts With Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of ASC 606 for one year. ASC 606 provides accounting guidance related to revenue from contracts with customers. For public business entities, ASC 606 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. This new revenue recognition standard (new guidance) has a five-step process: a) Determine whether a contract exists; b) Identify the performance obligations; c) Determine the transaction price; d) Allocate the transaction price; and e) Recognize revenue when (or as) performance obligations are satisfied. The Company has evaluated the impact of ASC 606 and does not currently believe that the application of ASC 606 will have a material impact on its condensed financial statements and disclosures, as the Company has already implemented the five-step process in determining revenue recognition from contracts with customers. The Company provides consulting and management services. A portion of these services were provided to a related party.
Basic and Diluted Net Income Per Common Share	Basic and Diluted Net Income per Common Share Basic net income per share is computed by dividing the net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing the net income by the weighted average number of common shares outstanding for the period and, if dilutive, potential common shares outstanding during the period. Potentially dilutive securities consist of the incremental common shares issuable upon exercise of common stock equivalents such as stock options and convertible debt instruments. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. There were no potentially dilutive securities outstanding at March 31, 2019 or 2018.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition” and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, which defers by one year the effective date of ASU 2014-09. Accordingly, this guidance is effective for the Company on October 1, 2018. The Company does not expect that the adoption of ASU 2014-09 will have a material impact on its financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, “Leases” which, for operating leases, requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The ASU is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company has evaluated the impact of the adoption of ASU 2016-02 and does not currently believe that it will have a material impact on its condensed financial statements and disclosures.
