You cannot use ANY content from the report you created for your organization: whether or not there was a non-competition agreement, you did that for your employer, which means that they own that report. (When you create something as part of your employment or for your employer, they own the copyright to that material.) You can create and market  a wholly new (written from scratch) report on the same topic, since you are evidently not contractually restricted from doing so. They key thing is, no content (words, graphics, charts, etc.) can be reused.
