I did not receive any sort of 1099 or "official" tax document for this, only a letter from Stifel stating the amount of interest paid.
More info:
"The SPA Account is a Line of Credit secured by your investments or marketable securities." "The Stifel Pledged Asset, or SPA Loan Account, keeps your assets in place while providing you access to the equity within those assets as cash." "The SPA Account is a demand loan using the assets in the account as collateral."
