Background information: The original context is that I was relating an incident via email, where my colleague told a customer that some of our actions were part of the organisation's policy. The policy is still valid, but the statement I used to relate the incident in my email went like this:

• "Mr Jay was informed that it was our policy to do this."

And I received feedback that it should go like this instead:

• "Mr Jay was informed that it is our policy to do this."
