In the event the one year constant maturity treasury yield is converted to a different standard reference base or otherwise revised, the determination of interest shall be made with the use of such converted or revised standard reference base. In the event the board of governors of the federal reserve system ceases to publish a converted or revised rate, interest shall be calculated at a rate published by the United States Treasury Department, or other comparable entity, that establishes a rate reflecting or best approximating the market conditions for one year investments at the time of the taking and each additional year that interest is owed pursuant to subdivision (2) above.
Any action brought under this section shall, upon motion of either party, be given priority for expedited hearing.
