Page 3 gives a high level description but nothing about specific corrective actions.

"In a limited number of cases, Micron's audits of suppliers find labor conditions that do not meet company and industry expectations. In such cases, Micron works with suppliers to ensure proper and timely corrective actions are implemented and labor issues are resolved. As audits expand into the supply chain, more issues may be identified because of the larger number of suppliers covered".

The statement is indeed quite vague, but they do mention working with suppliers to implement corrective actions. Therefore, I have selected the Corrective action plan option.
