(e) (1) Except as otherwise provided in this subsection, on and after July 1, 1996, the rate of interest on judgments rendered by courts of this state pursuant to the code of civil procedure shall be at a rate per annum: (A) Which shall change effective July 1 of each year for both judgments rendered prior to such July 1 and judgments rendered during the twelve-month period beginning such July 1; and (B) which is equal to an amount that is four percentage points above the discount rate (the charge on loans to depository institutions by the New York federal reserve bank as reported in the money rates column of the Wall Street Journal) as of July 1 preceding the date the judgment was rendered.

The burden of proving that a different amount is the correct total shall lie with any person contesting the presumed amount.
