(a) Beginning date. Except as provided in paragraph (d) of this section, an extended benefit period or high unemployment period begins in a State on the first day of the third calendar week after a week for which there is a State “on” indicator in that State under either § 615.12(a) or (b).

(b) Ending date. Except as provided in paragraphs (c) and (e) of this section, an extended benefit period or high unemployment period in a State ends on the last day of the third week after the first week for which there is a State “off” indicator in that State, unless another indicator is in “on” status.

(c) Duration. When an extended benefit period and/or high unemployment period becomes effective in any State, or triggers “off,” the attained status must continue in effect for not less than 13 consecutive weeks.

(d) Limitation. No extended benefit period or high unemployment period may begin or end in any State before the most recent week for which data used to trigger the State “on” or “off” or “no change” indicator has been published.

(e) Specific applications of the 13-week rule. (1) If a State concludes a 13-week mandatory “on” period by virtue of the IUR indicator which, at the end of the 13-week period no longer satisfies the requirements for a State to be “on,” the extended benefit period continues if the TUR indicator is “on” during the 11th week of the 13-week mandatory “on” period.

(2) If a State concludes a 13-week mandatory “on” period by virtue of the TUR indicator which, at the end of the 13-week period no longer satisfies the requirements for a State to be “on,” the extended benefit period continues if the IUR indicator is “on” during the 11th week of the 13-week mandatory “on” period.

(f) Determining if a State remains “off” as a result of a total unemployment rate indicator after the 13-week mandatory “off” period ends. (1) The State remains “off” if there is not an IUR “on” indicator the 11th week of the 13-week mandatory “off” period, and there is a TUR “off” indicator for the third week before the last week of the 13-week mandatory “off” period.
