New Accounting Pronouncement or Change in Accounting Principle, Description	Effective February 1, 2018, the Companyadopted ASU 2016-18 “Statement of Cash Flows (Topic 230), Restricted Cash”. This standard requires that thestatements of cash flows explain the changes in the combined total of restricted and unrestricted cash balances. Amounts generallydescribed as restricted cash will be combined with unrestricted cash and cash equivalents when reconciling the beginning and endof period balances on the statements of cash flows. The Company adopted this standard retrospectively. Therefore, the beginningperiod balance of cash and cash equivalents as of January 31, 2017 was increased by $130,000, the end of period balance of cashand cash equivalents as of October 31, 2017 was increased by $230,000 and the beginning period balance of cash and cashequivalents as of January 31, 2018 was increased by $354,000 to reflect the respective restricted cash amounts.
Accounting Standards Update 2016-02 [Member]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Details) [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	In February 2016, the FASB issued ASU 2016-02“Leases”. This standard requires that virtually all leases will be recognized by lessees on their balance sheet asa right-of-use asset and a corresponding lease liability, including leases currently accounted for as operating leases. The Companywill be required to adopt this standard effective February 1, 2019. The related leases are currently accounted for as operatingleases (see Note 5). This standard requires a modified retrospective transition approach and allows for early adoption. In July2018, FASB issued Accounting Standards Update, Leases (Topic 842): Targeted Improvements, which provides an option to applythe transition provisions of the new standard at the adoption date instead of the earliest comparative period presented in thefinancial statements. The Company has not completed its analysis of the effect of adopting this guidance but it does expect theadoption of this guidance to have a material impact on its Consolidated Balance Sheet related to the right-of-use asset and leaseobligation liability to be recognized upon adoption of this guidance in addition to requiring expanded disclosures in the Company’sconsolidated financial statements. The Company expects to complete its analysis of the impact of adopting this guidance duringthe fourth quarter of fiscal year 2018.
