Were INCOME TAX disclosures among SVB's accounting red flags..?

Just for a discussion and a food-for-thought ;-)

Based on the extracts shared below (all from SVB's 10-K for 2022), please note that:

(1) for the whole FY 2022, SVB reported a US GAAP-based "Income before income tax expense" of 2.172 USD m (so, positive, even if shrinking), compared to 2.724 USD m a year before

(2) at the same time, it PAID NO EFFECTIVE INCOME TAXES in FY 2022 - please take a look at total CURRENT INCOME TAXES (which reflect taxes payable, based on the company's taxable income, instead of US GAAP earnings), which in FY 2022 were NEGATIVE (i.e. excess of tax refunds over taxes paid), amounting to -28 USD m, compared to positive taxes amounting to +659 USD m in FY 2021

(3) this suggests that the company could have INCURRED A TAX LOSS (despite positive pre-tax accounting earnings, as reported in its income statement), in its FY 2022, which seems corroborated by a sharp increase in the carrying amount of what they call "Net operating loss carryforwards" (that rose from 7 USD m to 1.650 USD m)

Would You (at least those of You who are familiarized with nuances of contemporary financial reporting) consider it as thought-provoking RED FLAGS..? ;)
