It hasn't been an easy year for the world's wealthiest individuals.
Volatile stock markets, tanking oil prices and a stronger dollar led to a dramatic reshuffling of wealth around the globe and a drop in billionaire fortunes for the first time since 2009, according to Forbes.
In its 30th annual guide to the world's richest people, Forbes found 1,810 billionaires, down from a record 1,826 a year ago. Sixteen individuals with ties to the insurance industry — down from 20 last year — made Forbes' 2016 list of world billionaires.
This year's billionaires with connections to the insurance industry include the son of a Chicago meat-packer, a former appliance door-to-door salesman, a World War II flight navigator and a passionate environmentalist.
Overall, the United States has 540 billionaires, more than any other country in the world. It's followed by mainland China with 251 and Germany with 120.
Here are the world's 16 billionaires with wealth linked to insurance, according to Forbes' 2016 list.
No. 1,694: Ion Tiriac, 76 (Bucharest, Romania)
Net worth: $1.14 billion.
Source of wealth: banking, insurance, self-made.
Financial and real estate investor Ion Tiriac hold shares in insurance and auto leasing concerns and still runs his high-end car museum dedicated to his cars and motorcycles from Jaguar, Bentley, Mercedes-Benz, Rolls Royce and their ilk.
Tiriac competed in the 1960 Olympics as an ice hockey player and later switched to tennis, eventually coaching several tennis greats, including Boris Becker, Steffi Graf and Goran Ivanisevic. Most recently, he advised Romanian tennis ace Simona Halep to sign sponsorship contracts with companies such as Adidas and Vodafone.
No. 1,577 (4-way tie): William Berkley, 69 (Greenwich, Conn.)
Net worth: $1.14 billion.
Source of wealth: insurance, self-made.
William R. Berkley got the entrepreneurial bug as a young man. He founded insurance company W.R. Berkley Corp. in 1967 with just $2,500 while he was an MBA student at Harvard. The company, which had $5.3 billion in revenue in 2013, does business through 27 subsidiaries that insure everything from mobile surgery units to jewels to fine art. One of its fastest-growing units insures sports and entertainment companies.
Berkley took the company public in 1974. Revenue surpassed the $1 billion mark in 1995 after nearly two decades of acquisitions. He has a nearly 20% stake, though roughly half of his shares are pledged as collateral for loans. For this reason, Forbes applied a 50% discount to the pledged shares. Berkley is chairman and CEO. His son, W. Robert Berkley, is president and chief operating officer.

Based in Cardiff, Admiral also has operations in Spain, France, Italy and the United States. Its American brands include Elephant Auto Insurance and Comparenow.com. Admiral is known for its lighthearted, employee-friendly culture. Its "Ministry of Fun" organizes events for all staff members, such as dress-up days, rock band contests and surfing trips.

He paid his way through school by selling appliances door to door. After a stint as an investment analyst, Watsa struck out on his own in 1984.
Watsa began snatching up insurance companies, modeling his business after the success of his idol: Warren Buffett.

Like Buffett, he's a pragmatic investor and a major philanthropist. In 2013, Munger pledged more than $100 million for new graduate residences at the University of Michigan, and in 2014, he gave $65 million to the University of California, Santa Barbara's Kavli Institute for Theoretical Physics for a new visitor's residence.
