To calculate the interest payments for the shipping company's bonds, we use the simple interest formula applied to each compounding period (quarter), as the interest is paid out to bondholders.

### 1. Quarterly Interest Payment

The quarterly interest rate is the annual rate divided by the number of quarters in a year.

* **Principal ():** 
* **Annual Rate ():** 
* **Quarters per year ():** 

**The company will have to pay $24.75 million in quarterly interest.**

### 2. Interest Paid Over a 12-Year Period

To find the total interest over 12 years, we multiply the quarterly payment by the total number of quarters in that timeframe.

* **Number of Quarters:** 

**The company will pay $1,188 million (or $1.188 billion) in interest over the 12-year period.**
