Effective on May 3, 2018, Superior Uniform Group, Inc. changed its name to Superior Group of Companies, Inc. The accompanying unaudited financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. Intercompany items have been eliminated in consolidation. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10 -K for the year ended December 31, 2018 , and filed with the Securities and Exchange Commission. The interim financial information contained herein is not certified or audited; it reflects all adjustments (consisting of only normal recurring accruals) which are, in the opinion of management, necessary for a fair statement of the operating results for the periods presented, stated on a basis consistent with that of the audited financial statements. The results of operations for any interim period are not necessarily indicative of results to be expected for the full year. We refer to the condensed consolidated financial statements collectively as “financial statements,” and individually as “statements of comprehensive income”, “balance sheets”, “statements of stockholders’ equity”, and “statements of cash flows” herein.
New Accounting Pronouncements, Policy [Policy Text Block]	b) Recent Accounting Pronouncements We consider the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not listed below were assessed and determined to be not applicable. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016 - 02, Lea s es (Topic 842 ) and July 2018, the FASB issued ASU 2018 - 10, Codification Improvements to Topic 842, Leases and ASU 2018 - 11, Targeted Improvements (collectively “Topic 842” ). Topic 842 establishes a new lease model, referred to as the right-of-use (ROU) model that brings substantially all leases onto the balance sheet. This standard requires lessees to recognize leased assets (ROU Assets) and lease liabilities on the balance sheet and disclose key information about the leasing arrangements in their financial statements. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted Topic 842 effective on January 1, 2019 using the modified retrospective transition approach that allows a reporting entity to use the effective date as its date of initial application and not restate the comparative periods in the period of adoption when transitioning to the new standard. Consequently, the requisite financial information and disclosures under the new standard are excluded for dates and periods prior to January 1, 2019. In addition, the Company elected to use a number of optional simplification and practical expedients (reliefs) permitted under the transition guidance within the new standard, including allowing the Company to combine fixed lease and non-lease components, apply the short-term lease exception to all leases of one year or less, and utilize the ‘package of practical expedients’, which permits the Company to not reassess prior accounting conclusions with respect to lease identification, lease classification and initial direct costs under Topic 842. The Company did not elect the use-of hindsight or the practical expedient pertaining to land easement; the latter not being applicable to the Company. Adoption of this new standard resulted in the recognition of $4.1 million of operating lease liabilities ( $1.0 million in other current liabilities and $3.1 million in long-term operating lease liabilities) which represented the present value of the remaining lease payments of $4.6 million, discounted using the Company’s lease discount rate of 5.74% and $4.9 million of operating lease right-of-use assets, which represents the lease liability of $4.1 million adjusted for prepaid rent to $0.8 million that was previously presented within current prepaid expenses and other current assets and other assets on the accompanying balance sheet prior to adoption. Refer to Note 10 for the impact to the financial statements as of September 30, 2019 . 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. ” ASU 2018 - 02 allows entities to elect to reclassify the income tax effects resulting from the Tax Cuts and Jobs Act (Tax Act) on items within accumulated other comprehensive income to retained earnings and requires additional related disclosures. This standard is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company elected not to reclassify the income tax effects of the Tax Act from accumulated other comprehensive income to retained earnings. The Company’s adoption of this standard on January 1, 2019 did not have a material impact on its financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016 - 13, “ Financial Instruments—Credit Losses (Topic 326 ). ” The update changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. In August 2019, the FASB proposed an amendment to ASU 2016 - 13, “ Financial Instruments—Credit Losses (Topic 326 )” that would delay the effective date for Smaller Reporting Companies until fiscal years beginning after December 15, 2022. Adoption will require a modified retrospective approach beginning with the earliest period presented. The Company is currently evaluating the potential impact this standard will have on its financial statements. In January 2017, the FASB issued ASU 2017 - 04, “Simplifying the Test for Goodwill Impairment.” ASU 2017 - 04 eliminates the two -step process that required identification of potential impairment and a separate measure of the actual impairment. Goodwill impairment charges, if any, would be determined by the difference between a reporting unit's carrying value and its fair value (impairment loss is limited to the carrying value). This standard is effective for annual or any interim goodwill impairment tests beginning after December 15, 2019. The Company’s adoption of this standard is not expected to have a material impact on its financial statements. In August 2018, the FASB issued ASU 2018 - 15, “Internal-Use Software (Subtopic 350 - 40 ): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The update also requires an entity to expense the capitalized implementation costs of a hosting arrangement over the term of the hosting arrangement. This update is effective for fiscal years beginning after December 15, 2019 and may be applied prospectively or retrospectively. The Company’s adoption of this standard is not expected to have a material impact on its financial statements.
