2.__On contracts and notes.__In all civil and small claims actions involving a contract or note that contains a provision relating to interest, prejudgment interest is allowed at the rate set forth in the contract or note.

3.__Other civil actions; rate.__In civil actions other than those set forth in subsections 1 and 2, prejudgment interest is allowed at the one-year United States Treasury bill rate plus 3%.

A.__For purposes of this subsection, "one-year United States Treasury bill rate" means the weekly average one-year constant maturity Treasury yield, as published by the Board of Governors of the Federal Reserve System, for the last full week of the calendar year immediately prior to the year in which prejudgment interest begins to accrue.

B.__If the Board of Governors of the Federal Reserve System ceases to publish the weekly average one-year constant maturity Treasury yield or it is otherwise unavailable, then the Supreme Judicial Court shall annually establish by rule a rate that most closely approximates the rate established in this subsection.

4.__Stated rate.__When prejudgment interest is awarded pursuant to subsection 2 or 3, the applicable rate must be stated in the judgment.

5.__Accrual; suspension; waiver.__Prejudgment interest accrues from the time of notice of claim setting forth under oath the cause of action, served personally or by registered or certified mail upon the defendant until the date on which an order of judgment is entered.__If a notice of claim has not been given to the defendant, prejudgment interest accrues from the date on which the complaint is filed.__In actions involving a contract or note that contains a provision relating to interest, the rate of interest is fixed as of the time the notice of claim is given or, if a notice of claim has not been given, as of the date on which the complaint is filed.__If the prevailing party at any time requests and obtains a continuance for a period in excess of 30 days, interest is suspended for the duration of the continuance.__ On petition of the nonprevailing party and on a showing of good cause, the trial court may order that interest awarded by this section be fully or partially waived.

6.__Effect on post-judgment interest.__This section does not affect post-judgment interest imposed by section 1602-C.
