Basis of presentation [Text Block]

Basis of presentation. The interim consolidated financial statements of Perma-Pipe International Holdings, Inc. and subsidiaries ("PPIH," "Company," or "Registrant") are unaudited, but include all adjustments that the Company's management considers necessary to present fairly the financial position and results of operations for the periods presented. These adjustments consist of normal recurring adjustments. Information and footnote disclosures have been omitted pursuant to Securities and Exchange Commission ("SEC") rules and regulations. The consolidated balance sheet as of January 31, 2017 is derived from the audited consolidated balance sheet as of that date. The results of operations for any interim period are not necessarily indicative of future or annual results. Interim financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's latest Annual Report on Form 10-K. The Company's fiscal year ends on January 31. Years and balances described as 2017 and 2016 are for the six months ended July 31,2017 and 2016, respectively.

In February 2017, the Company announced that the board of directors had authorized Company management to move forward with the re-naming and re-branding of MFRI, Inc. under the Perma-Pipe name now that the Company operates in a single business segment under the Perma-Pipe brand, and the Company believes this decision will better serve its strategy, position it well in the industry and global market, and better reflect the Company’s mission and strategy, and positions it to leverage the strong reputation Perma-Pipe has established since beginning operations.  The name change to Perma-Pipe International Holdings, Inc. was effective March 20, 2017.  The Company's common stock has been and will continue to be reported under its new ticker symbol “PPIH” since March 21, 2017.
