Nature of Business and Basis of Presentation	Note 1: Nature of Business and Basis of Presentation Organization The Bank of South Carolina (the “Bank”) was organized on October 22, 1986 and opened for business as a state-chartered financial institution on February 26, 1987, in Charleston, South Carolina. The Bank was reorganized into a wholly-owned subsidiary of Bank of South Carolina Corporation (the “Company”), effective April 17, 1995. At the time of the reorganization, each outstanding share of the Bank was exchanged for two shares of Bank of South Carolina Corporation Stock. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. In consolidation, all significant intercompany balances and transactions have been eliminated. References to “we”, “us”, “our”, “the Bank”, or “the Company” refer to the parent and its subsidiary that are consolidated for financial purposes. Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), for the interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, our interim consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 3, 2018. In the opinion of management, these interim financial statements present fairly, in all material respects, the Company’s consolidated financial position and results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period. Accounting Estimates and Assumptions The preparation of the consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ significantly from these estimates and assumptions. Material estimates generally susceptible to significant change are related to the determination of the allowance for loan losses, impaired loans, other real estate owned, deferred tax assets, the fair value of financial instruments and other-than-temporary impairment of investment securities. Reclassification Certain amounts in the prior years’ financial statements have been reclassified to conform to the current period’s presentation. Such reclassifications had no effect on shareholders’ equity or the net income as previously reported. Income per share Basic income per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. Dilutive income per share is computed by dividing net income by the weighted-average number of common shares and potential common shares outstanding. Potential common shares consist of dilutive stock options determined using the treasury stock method and the average market price of common stock. Retroactive recognition has been given for the effects of all stock dividends. Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. We have reviewed events occurring through the date the financial statements were available to be issued and no subsequent events occurred requiring accrual or disclosure. Recent Accounting Pronouncements The following is a summary of recent authoritative pronouncements that could impact the accounting, reporting and/or disclosure of financial information by the Company. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, Topic 606. The core principle of the new standard is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. This guidance also includes expanded disclosure requirements that result in an entity providing users of financial statements with comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. The guidance became effective January 1, 2018. The amendment does not apply to revenue associated with financial instruments, such as loans and investment securities available for sale, and therefore had no material effect on our consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10); Recognition and Measurement of Financial Instruments and Financial Liabilities. This update addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments became effective on January 1, 2018 and did not have a material effect on the financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which revises certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the effect that implementation of the new standard will have on our results of operations and cash flows, and financial position. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), to clarify the implementation guidance on principal versus agent considerations and address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The guidance became effective January 1, 2018. The Company completed an assessment of revenue streams and a review of related contracts potentially affected by the ASU and, based on this assessment, the Company concluded that the ASU did not materially change the method in which the Company currently recognizes revenue for these revenue streams. As such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to clarify guidance related to identifying performance obligations and accounting for licenses of intellectual property. The amendment became effective for the Company January 1, 2018 and did not have a material effect on the financial statements. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow- Scope Improvements and Practical Expedients, to clarify guidance related to collectability, noncash consideration, presentation of sales tax, and transition. The amendment became effective on January 1, 2018 and did not have a material effect on the financial statements. In June 2016, the FASB issued ASU 2016-13, Financial instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to change the accounting for credit losses and modify the impairment model for certain debt securities. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. Early adoption is permitted for all organizations for periods beginning after December 15, 2018. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendment became effective on January 1, 2018 and did not have a material effect on the financial statements. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. These corrections make a limited number of revisions to several pieces of the revenue recognition standard issued in 2014. The amendment became effective on January 1, 2018 and did not have a material effect on the financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which provided guidance to assist with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is intended to address concerns that the existing definition of a business has been applied too broadly and has resulted in many transactions being recorded as business acquisitions that in substance are more akin to asset acquisitions. The amendments became effective on January 1, 2018 and did not have a material effect on the financial statements. In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, to clarify the scope of established guidance on nonfinancial asset derecognition, issued as part of ASU 2014-09, Revenue from Contracts with Customers, as well as accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. The amendments became effective on January 1, 2018 and did not have a material effect on the financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization of Purchased Callable Debt Securities, which shortens the amortization period for the premium to the earliest call date. The amendment will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect this amendment to have a material effect on its financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Cuts and Jobs Act (the 2017 Tax Act”). The Company adopted this pronouncement early by retrospective application to each period in which the effect of the change in the tax rate under the 2017 Tax Act is recognized. The impact of the reclassification from other comprehensive income to retained earnings was included in the Statement of Changes in Shareholders’ Equity for the year ended December 31, 2017. In February 2018, the FASB issued ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities to clarify certain aspects of the guidance issued in ASU 2016-01. The amendments will be effective for the third quarter of 2018 subsequent to adopting the amendments in ASU 2016-01. All entities may early adopt these amendments for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, as long as they have adopted ASU 2016-01. The Company does not expect these amendments to have a material effect on its financial statements. In March 2018, the FASB issued ASU 2018-4, Investments—Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 which incorporate into the Accounting Standards Codification recent SEC guidance which was issued in order to make the relevant interpretive guidance consistent with current authoritative accounting and auditing guidance and SEC rules and regulations. The amendments were effective upon issuance. The Company does not expect these amendments to have a material effect on its financial statements. In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The amendments incorporate into the Accounting Standards Codification recent SEC guidance related to the income tax accounting implications of the Tax Cuts and Jobs Act. The amendments were effective upon issuance. The Company does not expect these amendments to have a material effect on its financial statements. In May 2018, the FASB amended the Financial Services – Depository and Lending Topic of the ASC to remove outdated guidance related to Circular 202. The amendments were effective upon issuance and did not have a material effect on the financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on our financial position, results of operations or cash flows.
