Nuveen Select Tax-Free Income Portfolio (NXP) earnings

Per-share earnings history isn't available for Nuveen Select Tax-Free Income Portfolio. SEC EDGAR doesn't carry the standard GAAP per-share concepts (EarningsPerShareBasic / EarningsPerShareDiluted) for this filer — alternative- asset managers and pre-conversion limited partnerships sometimes report Distributable Earnings or per-unit metrics instead, which we don't chart here.

See the full list of XBRL line items NXP reports to SEC EDGAR — revenue, net income, balance-sheet, cash-flow, and dividend-per- share history are still available there.
