(Bloomberg Business) — New fathers in the United States lack something that the governments of 96 other countries, including Croatia, Albania, and Serbia, require companies to offer: paid paternity leave. But at a handful of companies, fathers can take months off with pay, take advantage of on-site child-care centers, or have the cost of adoption and family planning covered, a new report shows.

For a report released Thursday, Fatherly, a lifestyle site geared toward young fathers, partnered with management professors at the Wharton School and the Silberman College of Business. They looked at 50 U.S. companies that offer at least one week of paid paternity leave and employ at least 1,000 workers and graded them based on the length of paid leave they offer, plus such additional perks as flex-time policies and a culture that promotes work-life balance.

Check out the 10 companies with the best paternity leave policies below and see the full list on Fatherly's website.
