Maersk's port company APM Terminals has delivered positive results for years and also brought in hundreds of millions to the conglomerate last year. And this in spite of a moderate growth in the global trade and a global economy that, according to the International Monetary Fund (IMF), has declined.

This week the IMF lowered its projected growth for the current year, now expected to finish around 3.3 percent, down from projected 3.8 percent before. Yet APM Terminals still looks like a business that delivers time and again in spite of the challenges caused by a slow global economy.
