What are dividends and how are they taxed?

Hi

I have a couple of question on the INVIT which please clarify:

  1. Is the TDS applicable for the unitholders at 10% subject to the limit beyond Rs.5,000/- as is applicable for equities and debt instruments where dividends and interests are paid respectively?
  2. The tax exemption component of Dividend and the treasury income are exempted merely from TDS or is it exempt from the tax obligation of the assessee?
