The end of 2014 marked Neuberger Berman's return to full employee ownership, highlighting the firm's independence and clearing the path for future growth. Employee ownership has been recognized by industry leaders as a key factor in the success of asset management firms, and Neuberger Berman's position as an employee-owned firm is cited as a reason for its high talent retention rate. In recognition of its culture, Neuberger Berman won the top rank in its category on "Pensions & Investments"' 2016 Best Places to Work in Money Management survey, and had been named to the Best Places list in 2013, 2014, and 2015. In October 2016, the firm moved its global headquarters to 1290 Avenue of the Americas in midtown Manhattan. In addition, the firm has approximately 28 other offices in key countries around the world. Regional headquarters are in Hong Kong, London and Tokyo, and has additional primary portfolio management centers in Atlanta, Chicago, Dallas, Milan, The Hague and Singapore. Former headquarters in New York City include 605 Third Avenue, 522 Fifth Avenue and, originally, The Biltmore Hotel. Collectively, Neuberger Berman's philanthropic efforts are called NB Impacts. NB Impacts includes both employee community service and the grant-making actions of the Neuberger Berman Foundation. The Neuberger Berman Foundation offers grants focusing on at-risk children, youth educational programs, and economic sustainability. Neuberger Berman conducts an annual week-long program in the spring called “Celebration with Service,” which holds community service events in the cities where the firm has offices. For its 75th anniversary year in 2014, the firm's “Celebration with Service” supported 75 volunteer projects worldwide. Since 2012, NB Impacts has deployed more than 4,500 volunteers to work with over 5,000 youth and 800 senior citizens, and also includes approximately 2,000 volunteer hours spent on improving parks and community spaces. Through the years, some of the programs Neuberger Berman has been involved in are: The Y, Homes for Heroes, Per Scholas, C-CAP, New York City Service, and Habitat for Humanity. Contemporary art in the workplace has been part of Neuberger Berman's corporate culture since 1939, when collector Roy Neuberger co-founded the investment firm. In 1990 the firm began developing its own art collection. The firm's corporate art collection was absorbed into the Lehman Brothers collection but Neuberger Berman repurchased, many of them when the collection was sold at auction in 2010.
