Enduring materials that are offered over the course of multiple calendar years should be reported only once in PARS with a start and end date spanning up to 3 years. Learner counts for enduring activities should be updated in PARS through 12/31 by the 3/31 annual reporting deadline for each year they are active. For example, if a provider offers an enduring material that was launched on July 1, 2023, and remains available through December 2024 they should:  Report one activity in PARS with a start date of 07/01/2023 and an end date of 12/31/2024. Report the number of learners through 12/31/2023 as a part of annual reporting for 2023 and then update those learner counts to indicate the cumulative number of learners through 12/31/2024 as a part of annual reporting for 2024. If the activity received monetary commercial support, report the amount of support received in the year in which it was received. Other activity formats that span more than one calendar year should be entered once for each 12-month period and closed at the end of that period. If the activity will continue beyond a 12-month period, it should be entered again as a separate activity in PARS. For each 12-month period that the activity was provided, report the number of learners (physicians and/or other learners) who participated, as well as the income related to the activity.
