Notes to Financial Statements
Basis of Accounting [Text Block]	Note 1. Basis of Presentation The accompanying (a) condensed balance sheet as of September 30, 2019, which has been derived from audited financial statements, and (b) unaudited interim condensed financial statements as of and for the three and nine months ended June 30, 2020 have been prepared by Clearfield, Inc. (the “Company”) in accordance with accounting principles generally accepted in the United States of America for interim financial information, pursuant to the rules and regulations of the Securities and Exchange Commission. Pursuant to these rules and regulations, certain financial information and footnote disclosures normally included in the financial statements have been condensed or omitted. However, in the opinion of management, the financial statements include all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the financial position, results of operations and cash flows of the interim periods presented. Operating results for the interim periods presented are not necessarily indicative of results to be expected for the full year or for any other interim period, due to variability in customer purchasing patterns and seasonal, operating and other factors. These condensed financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2019. In preparation of the Company’s financial statements, management is required to make estimates and assumptions that affect reported amounts of assets and liabilities and related revenues and expenses during the reporting periods. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Recently Adopted Accounting Pronouncements Effective October 1, 2019 we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, Leases, using the effective date method under the modified retrospective approach. The amended guidance requires lessees, at the commencement date, to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and to record a right-of-use (“ROU”) asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. In July 2018, the FASB issued ASU 2018-11, Leases, Targeted Improvements, which gave companies the option of applying the new standard at the adoption date, rather than retrospectively to the earliest period presented in the financial statements. The Company elected the package of practical expedients permitted under the new standard, which among other things, allowed the Company to carry forward the historical lease classification. The Company also elected the practical expedient to not recognize a lease liability and ROU asset for short-term leases less than 12 months. We chose the option to apply the new standard at the adoption date, and therefore we are not required to restate the financial statements for prior periods, nor are we required to provide the disclosures required by the new standard for prior periods. Upon adoption, we recognized an approximate $2.4 million right-of-use asset, and an approximate $2.6 million lease liability. Our adoption of the new standard did not impact our cash flows or have a material impact on our results of operations. We have expanded our financial statement disclosures to comply with the requirements of the new standard.
