In our opinion, the financial statement presents fairly, in all material respects, the financial position of the Company as of December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. #### **Basis for Opinion** This financial statement is the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statement based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statement is free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. Our audit included performing procedures to assess the risks of material misstatement of the financial statement, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statement. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statement. We believe that our audit provides a reasonable basis for our opinion. We have served as the Company's auditor since 2021.

96,642 | {8}------------------------------------------------ #### **Notes to Financial Statement** ### **1. Organization** Mainline Securities, LLC ("Company") was established on August 18, 2014 and is organized under the laws of the state of Delaware. Effective March 28, 2016 the Company registered as a brokerdealer under the Securities Exchange Act of 1934, as amended. The Company is a member of the Financial Industry Regulatory Authority ("FINRA"). The Company is wholly-owned by Mainline Investment Partners LLC ("MLIP" or "Member"). The primary business of the Company is to provide assistance in capital raises for private placement offerings and with selling of various insurance products. # **2. Summary of Significant Accounting Policies** The following is a summary of the significant accounting policies applied by management in the preparation of the accompanying financial statement. #### *Estimates* The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. #### *Income Taxes* The Company is a single-member Limited Liability Company and is treated as a disregarded entity for federal income tax purposes. Generally, disregarded entities are not subject to entity-level federal or state income taxation and, as such, the Company does not provide for income taxes under FASB ASC 740, "Income Taxes". The Company's taxable income is reported in the tax return of its single member, MLIP. Based upon its evaluation, the Company has concluded that there are no significant uncertain income tax positions relevant in the jurisdictions where it is required to file income tax returns requiring recognition in the statement of financial condition. Management monitors proposed and issued tax law, regulations and cases to determine the potential impact to uncertain income tax positions. At December 31, 2022, management had not identified any potential subsequent events that would have a material impact on unrecognized income tax benefits. The Company believes its tax status as a pass through entity would be sustained under Federal, state, or local income tax examination. The Company is subject to examination by taxing authorities in various jurisdictions. The open tax years subject to examination vary by jurisdiction but in general are the preceding three years. The Company is not currently under examination by any taxing authority. {9}------------------------------------------------ #### **Notes to Financial Statement** ## 3**. Concentrations** #### *Cash Balances* The Company maintains its cash in a bank account which, at times, may exceed federally insured limits. The Company mitigates this risk by only depositing funds with a major institution and has not experienced any losses from maintaining cash account balances in excess of federally insured limits. #### **4. Related Party Transactions** #### *Expense Sharing and Administrative Services Agreement* The Company has an expense sharing and administrative services agreement with its sole member, MLIP, Mainline Investment Advisers, LLC ("MLIA"), Merion Realty Advisers, LLC ("Merion"), and Mainline Private Wealth, LLC ("MLPW"). MLIP, MLIA, Merion, and MLPW are collectively referred to as "Mainline Provider Affiliates." Under the terms of the agreement, the Mainline Provider Affiliates employ personnel who provide services to the Company, including management oversight, back office, and similar support, or from time to time may fund certain other expenses related to the operations of the Company such as facility rental costs, computer and IT costs, among other, to the Company. During 2022, the Company incurred administrative fees to Mainline Provider Affiliates for amounts incurred under the agreement, \$37,490 of which is payable as of December 31, 2022. In addition, the Company incurred broker dealer insurance expense from its sole member, \$12,072 of which is prepaid at year end. The Due to affiliated entities and prepaid expenses are included in the accompanying statement of financial condition. #### **5. Net Capital Requirements** The Company is subject to the Securities and Exchange Commission Uniform Net Capital Rule (SEC Rule 15c3-1), which requires the maintenance of minimum "net capital" and requires that the ratio of "aggregate indebtedness" to net capital, both as defined, shall not exceed 1500%. At December 31, 2022, aggregate indebtedness was \$39,390 and the ratio was 116.57%. At December 31, 2022, the Company had net capital, as defined, of \$33,790, which was \$28,790 in excess of its required net capital of \$5,000. ### **6. Subsequent Events** The company has evaluated the need for disclosures and/or adjustments resulting from subsequent events through February 15, 2023 the date the financial statement was issued. Based on this evaluation, no disclosures and/or adjustments were made to the financial statement. Source: SEC EDGAR via Adviser Search (https://search.stillhousedata.com).
