Paragraphs:
The long-term portion of the Company’s unrecognized tax benefits at March 31, 2019 and 2018 was $622,000 and $619,000, respectively, of which the timing of the resolution is uncertain. As of March 31, 2019 and 2018, $2.5 million and $2.1 million, respectively, of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets.
As of March 31, 2019, the Company’s net deferred tax assets of $6.7 million are subject to a valuation allowance of $6.7 million. It is possible, however, that some months or years may elapse before an uncertain position for which the Company has established a reserve is resolved. A reconciliation of unrecognized tax benefits is as follows:
The unrecognized tax benefit balance as of March 31, 2019 of $599,000 would affect the Company’s effective tax rate if recognized.
