Deloitte is the brand under which tens of thousands of dedicated professionals in independent firms throughout the world collaborate to provide audit, consulting, financial advisory, risk management, tax and related services to select clients. These firms are members of Deloitte Touche Tohmatsu Limited, a UK private company limited by guarantee (“DTTL”). Each DTTL member firm provides services in particular geographic areas and is subject to the laws and professional regulations of the particular country or countries in which it operates. Each DTTL member firm is structured in accordance with national laws, regulations, customary practice, and other factors, and may secure the provision of professional services in its territory through subsidiaries, affiliates, and other related entities. Not every DTTL member firm provides all services, and certain services may not be available to attest clients under the rules and regulations of public accounting. DTTL and each DTTL member firm are legally separate and independent entities, which cannot obligate each other. DTTL and each DTTL member firm are liable only for their own acts and omissions, and not those of each other. DTTL (also referred to as “Deloitte Global”) does not provide services to clients. The DTTL member firm in the United States is Deloitte LLP. Deloitte's offices in New York have over 5,000 professionals in Audit, Advisory, Financial Advisory Services, Tax, and Consulting. Deloitte's U.S. headquarters at 30 Rockefeller Plaza in Manhattan was awarded the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Certification at the Gold level for commercial interiors in 2013. Deloitte designed its headquarters as a next generation workplace, bringing to life the organization's commitment to cutting-edge technology, open and flexible work settings and conference and training facilities.
