Question about Mainstreet Capital dividends

Hello everyone,

Since many people here are invested in $MAIN (-0,28 %) there must be someone who can answer my questions. Does Mainstreet usually reclassify its dividends in the following year? At least I could see on their site that there is no ROC.

If so, what impact does this have on withholding tax or final withholding tax?

Thanks for your feedback.
