As the instructor you have several options to credit your team, via the Audit tool on the instructor dashboard –
By a loan, with an interest rate you decide and for as many years (within the game) you decide.
Or by a Grant budget increase, this is not a loan but a grant issued by you.
The financial details can be viewed using the Audit Decisions tool for you, the instructor and in the financial report for the students, where they can monitor the following fields:
Loan received /reimbursed
Loan interests paid
Exceptional cost or profit.
Additional information regarding loans and grants can be found in the Markstrat.6 Instructor guide part 2.
