Income tax, description		The US parent company, CREG is taxed in the US and, as of September 30, 2020, had net operating loss (“NOL”) carry forwards for income taxes of $1.54 million; for federal income tax purposes, the NOL arising in tax years beginning after 2017 may only reduce 80% of a taxpayer’s taxable income, and may be carried forward indefinitely. However, the coronavirus Aid, Relief and Economic Security Act (“the CARES Act”) issued in March 2020, provides tax relief to both corporate and noncorporate taxpayers by adding a five-year carryback period and temporarily repealing the 80% limitation for NOLs arising in 2018, 2019 and 2020. The management believes the realization of benefits from these losses may be uncertain due to the US parent company’s continuing operating losses. Accordingly, a 100% deferred tax asset valuation allowance was provided.
