Re: tax loss carryforwards, I can give you a definitive answer for RSHN or any other company, since all companies go by the same tax codes. For net operating cash losses prior to 2018 under former tax codes, the carryforward expired after 20 years. RSHN was founded in 1999, and that's why RSHN had previously stated that its tax loss carryforwards would *begin to expire* in 2019 (20 years after the company's founding). For net operating losses booked after 2018, the tax loss carryforward is indefinite and doesn't expire under current tax codes. In the case of RSHN, the vast majority of its tax loss carryforward (for losses booked from 2001 to 2020) should still be usable.
