Answer:
- News report on website and social media channels.
- Quarterly earnings call.
- Annual General meeting.
Step-by-step explanation:
As there are no options available, I listed three ways in order of ease of implementation.
Catherine could include the news in a news report or newsletter and post it on the company website and their social media platforms to ensure that as many of their shareholders as possible read it. This is the easiest method mentioned and can be done as soon as possible.
Catherine can also update the shareholders during Quarterly Earnings calls which is a webcast or teleconference where she will update shareholders on the happenings in the company. As this happens quarterly, Catherine may have to wait some time to use it so it is second in ease of use.
Catherine could also wait till the Annual General Meeting of the shareholders to do so but this could take quite a long time.
