The rate of interest for each year shall equal 4 percent plus the weekly average 1-year constant maturity Treasury yield as published by the Board of Governors of the Federal Reserve System for the last week in December of the preceding year.  The state court administrator shall distribute notice of the applicable rates of interest to all district courts.
