Washington Revised Code Title 51. Industrial Insurance § 51.32.075. Adjustments in compensation or death benefits

(1) On July 1, 1982, there shall be an adjustment for those whose right to compensation was established on or after July 1, 1971, and before July 1, 1982. The adjustment shall be determined by multiplying the amount of compensation to which they are entitled by a fraction, the denominator of which shall be the average monthly wage in the state under RCW 51.08.018 for the fiscal year in which such person's right to compensation was established, and the numerator of which shall be the average monthly wage in the state under RCW 51.08.018 on July 1, 1982.

(2) In addition to the adjustment established by subsection (1) of this section, there shall be another adjustment on July 1, 1983, for those whose right to compensation was established on or after July 1, 1971, and before July 1983, which shall be determined by multiplying the amount of compensation to which they are entitled by a fraction, the denominator of which shall be the average monthly wage in the state under RCW 51.08.018 for the fiscal year in which such person's right to compensation was established, and the numerator of which shall be the average monthly wage in the state under RCW 51.08.018 on July 1, 1983.

(3) In addition to the adjustments under subsections (1) and (2) of this section, further adjustments shall be made beginning on July 1, 1984, and on each July 1st thereafter through July 1, 2010, for those whose right to compensation was established on or after July 1, 1971. The adjustment shall be determined by multiplying the amount of compensation to which they are entitled by a fraction, the denominator of which shall be the average monthly wage in the state under RCW 51.08.018 for the fiscal year in which such person's right to compensation was established, and the numerator of which shall be the average monthly wage in the state under RCW 51.08.018 on July 1st of the year in which the adjustment is being made. The department or self-insurer shall adjust the resulting compensation rate to the nearest whole cent, not to exceed the average monthly wage in the state as computed under RCW 51.08.018.

(4) In addition to the adjustments under subsections (1), (2), and (3) of this section, further adjustments shall be made beginning July 1, 2012, and on each July 1st thereafter for those whose right to compensation was established on or after July 1, 1971. The adjustment shall be the percentage change in the average monthly wage in the state under RCW 51.08.018 for the preceding calendar year, rounded to the nearest whole cent. For claims whose right to compensation was established on or after July 1, 2011, no adjustment shall be made under this subsection until the second July 1st following the date of injury or occupational disease manifestation.
