Basis of Presentation	The accompanying financial statements include the consolidated accounts of The Hillman Companies, Inc. and its wholly-owned subsidiaries (collectively “Hillman” or the “Company”). Unless the context requires otherwise, references to "Hillman," "we," "us," "our," or "our Company" refer to The Hillman Companies, Inc. and its wholly-owned subsidiaries. The consolidated financial statements included herein have been prepared in accordance with accounting standards generally accepted in the United States of America (U.S. GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. References to 2018, 2017, and 2016 are for fiscal years ended December 29, 2018, December 30, 2017, and December 31, 2016, respectively. We are a wholly-owned subsidiary of HMAN Group Holdings Inc. (“Holdco”). Affiliates of CCMP Capital Advisors, LLC (“CCMP”) own 80.5% of Holdco's outstanding common stock, affiliates of Oak Hill Capital Partners III, L.P., Oak Hill Capital Management Partners III, L.P. and OHCP III HC RO, L.P. (collectively “Oak Hill Funds”) own 17.0% of Holdco's outstanding common stock, and certain current and former members of management own 2.5% of Holdco's outstanding common stock. Beginning with fiscal year 2017, the Company has changed from a calendar year ending on December 31 to a 52-53 week fiscal year ending on the last Saturday in December 2017, effective beginning with the first quarter of 2017. In a 52 week fiscal year, each of the Company’s quarterly periods will comprise 13 weeks. The additional week in a 53 week fiscal year is added to the fourth quarter, making such quarter consist of 14 weeks. The Company’s first 53 week fiscal year will occur in fiscal year 2022. The Company made the fiscal year change on a prospective basis and has not adjusted operating results for prior periods. The change does not materially impact the comparability of quarters or year ended 2018 to the quarters or years ended 2017 or 2016. The adoption of a 52-53 week year was not deemed a change in fiscal year for purposes of reporting subject to Rule 13a-10 or 15d-10; hence, no transition reports are required. Nature of Operations: The Company is comprised of three separate business segments, operating United States, Canada, and Mexico. In prior years, the Company had operations in Australia under the name The Hillman Group Australia Pty. Ltd. In the year ended December 31, 2016, the Company decided to exit the Australia market following the withdrawal from Australia of a key customer and recorded charges of $1,047 related to the write-off of inventory and other assets. In the year ended December 30, 2017, the Company fully liquidated its Australian subsidiary and reclassified the cumulative translation adjustment to income. The $638 gain was recorded as other income on the Consolidated Statement of Comprehensive Income (Loss) in year ended December 30, 2017. Hillman Group provides and, on a limited basis, produces products such as fasteners and related hardware items; threaded rod and metal shapes; keys, key duplication systems, and accessories; personal protective equipment such as gloves and eye-wear; builder's hardware; and identification items, such as tags and letters, numbers, and signs, to retail outlets, primarily hardware stores, home centers and mass merchants, pet supply stores, grocery stores, and drug stores. The Canada segment also produces fasteners, stampings, fittings, and processes threaded parts for automotive suppliers, industrial Original Equipment Manufacturers (“OEMs”), and industrial distributors. On November 8, 2017, the Company entered into an Asset Purchase Agreement with Hargis Industries, LP doing business as ST Fastening Systems ("STFS") and other related parties, pursuant to which Hillman acquired substantially all of the assets, and assumed certain liabilities, of ST Fastening Systems. ST Fastening Systems, which is located in Tyler, Texas, specializes in manufacturing and distributing threaded self-drilling fasteners, foam closure strips, and other accessories to the steel-frame, post-frame, and residential building markets. Pursuant to the terms of the Agreement, the Company paid a purchase price of $47,339 which reflects finalized purchase accounting adjustments for the ST Fastening Systems acquisition as of fiscal year-end 2018. The ST Fastening Systems business is included in the Company’s United States reportable segment. See Note 5 - Acquisitions for additional information. On August 10, 2018, the Company completed the acquisition of Minute Key Holdings, Inc. ("MinuteKey"), an innovative leader in self-service key duplicating kiosks for a total consideration of $156,289. MinuteKey has existing operations in the United States and Canada and be included in Hillman's United States and Canada reportable segments. See Note 5 - Acquisitions for additional information. On October 1, 2018, the Company completed the acquisition of Big Time Products ("Big Time"), a leading provider of personal protection and work gear products ranging from work gloves, tool belts and jobsite storage, for total consideration of $348,834.
