Customer (E), Company manager (I), Internal Revenue Service (E), Lender (E), Investor (E), Controller (I), Cost accountant (I), SEC (E).

Explanation:

First of all, we need to define what exactly is an External Decision Maker (E) and an Internal Decision Maker (I).

External Decision Makers, these are people outside the company that make decisions, for example: Customer, Internal Revenue Service, Lender, Investor and The U.S. Securities and Exchange Commission (SEC).

Customers are external because they don't belong to the company.

Internal Revenue Service is an institution of the  Government of the U.S., that's why is outside the company.

Lender, this person or financial institution is not involved in the company in self, only lends money to the company, that's it.

Investor, as it was said above, it's the person or institution that only lends the money to the company, without being part of the insides.

The U.S. Securities and Exchange Commission (SEC) is an institution of the U.S. Government, so it's outside the company.

Internal Decision Makers, these are people inside the company, they are absolutely involved in the direct decisions, for example, Company Manager, Controller and Cost Accountant.

Company Manager is the head of the company, the person in this position absolutely makes company decisions to coordinate all departments.

Controller, this person has the responsibility of all accounting related activities, that's why is an internal decision maker.

Cost Accountant, is an internal decision maker because is the person in this position has to be a financial specialist who determines costs of the products or services that the company offers.

So, there you have it, it's a pleasure to help.
