Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Hawthorn Bancshares, Inc. (the Company) through its subsidiary, Hawthorn Bank (the Bank), provides a broad range of banking services to individual and corporate customers located within the Missouri communities in and surrounding Jefferson City, Columbia, Clinton, Warsaw, Springfield, and the greater Kansas City metropolitan area. The Company is subject to competition from other financial and nonfinancial institutions providing financial products. Additionally, the Company and its subsidiaries are subject to the regulations of certain regulatory agencies and undergo periodic examinations by those regulatory agencies. The accompanying unaudited consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10‑Q, and Rule 10‑01 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and disclosures required by U.S. GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2018. The preparation of the consolidated financial statements includes all adjustments that, in the opinion of management, are necessary in order to make those statements not misleading. Management is required to make estimates and assumptions, including the determination of the allowance for loan losses, real estate acquired in connection with foreclosure or in satisfaction of loans, and fair values of investment securities available-for-sale that affect the reported amounts of assets and liabilities and 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 period. Actual results could differ from those estimates. The Company’s management has evaluated and did not identify any subsequent events or transactions requiring recognition or disclosure in the consolidated financial statements other than mentioned below. Stock Dividend On July 1, 2019, the Company paid a special stock dividend of four percent to shareholders of record at the close of business on June 15, 2019. For all periods presented, share information, including basic and diluted earnings per share, has been adjusted retroactively to reflect this change. Summary of Recent Transactions and Events On February 8, 2019, Hawthorn Bank, a wholly-owned subsidiary of the Company, completed the sale of its branch located in Branson, Missouri with total deposits of approximately $10.6 million to Branson Bank in Branson, Missouri. The transaction excludes loans assigned to the branch. The sale resulted in a pre-tax gain of approximately $2.2 million, or $1.7 million after tax. The following represents significant new accounting principles adopted in 2019: Leases On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842) which requires that lessees and lessors recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The ASU primarily affects lessee accounting, which requires the lessee to recognize a right-of-use asset (ROU) and a liability to make lease payments for those leases classified as operating leases. For leases with a term of 12 months or less, an election by class of underlying asset not to recognize lease assets and lease liabilities is permitted. The ASU also provides additional guidance as to the definition of a lease, identification of lease components, and sale and leaseback transactions. The Company's operating leases primarily relate to office space and bank branches. In January 2018, the FASB issued ASU 2018-01, which allows entities the option to apply the provisions of the new lease guidance at the effective date without adjusting the comparative periods presented. In July 2018, the FASB issued ASU 2018-10, which provides narrow-scope improvements to the lease standard and ASU 2018-11, which allows entities to choose an additional transition method, under which an entity initially applies the new lease standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under this transitional method, the entity shall recognize and measure the leases that exist at the adoption date and the prior comparative periods are not adjusted. The Company adopted this ASU as of January 1, 2019 using the transitional method. In addition, the Company utilized the practical expedients that allowed it to retain the classifications of existing leases, not re-assess if existing leases have initial direct costs, and hindsight when determining the lease term and assessment of impairment. The adoption of ASU 2016-02 and related transition guidance resulted in the recording of right-of-use assets and lease liabilities on the consolidated balance sheets of $2.3 million and $2.3 million, respectively; however, it did not have a material impact on the Company's other consolidated financial statements. See Note 7 - Leases for additional information. Derivatives and Hedging The FASB issued guidance within ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities (Topic 815) in August 2017. The amendments in ASU 2017-12 to Topic 815, Derivatives and Hedging, are intended to more closely align hedge accounting with companies' risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance also amends the presentation and disclosure requirements and changes how companies assess effectiveness. Under the new guidance, public companies will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge's effectiveness. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test if the company can reasonably support an expectation of high effectiveness throughout the term of the hedge. Additional disclosures include cumulative basis adjustments for fair value hedges and the effect of hedging on individual income statement line items. The amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The ASU did not have a significant effect on the Company's Consolidated Financial Statements.
