Okla. Admin. Code § 735:80-15-3
The State Treasurer may authorize amnesty programs to promote voluntary compliance with the Uniform Unclaimed Property Act, and may participate and cooperate with other state administrators of abandoned or unclaimed property programs in nationwide amnesty programs[60: 680]. The State Treasurer shall establish a "look back period" of a specified amount of time which shall be the period to which amnesty applies. When authorizing an amnesty program, the Treasurer shall establish the period of time in which holders or their authorized representatives, may file their reports or otherwise notify OST, in the manner specified in this Subchapter. This period of time shall be known as the "Amnesty Period." The Treasurer shall publicly announce an amnesty program through press releases or other methods, which are calculated to inform holders which have not previously reported, of the availability of the program. The method chosen is solely at the discretion of the State Treasurer.
