The Out on the Street conference of Wall Street leaders which first met in 2011 is holding its first European event.

Out on the Street: Europe will take place in London on Tuesday, November 13. Out on the Street member organizations include Bank of America Merrill Lynch, Barclays, Citibank, Credit Suisse, Deutsche Bank, Goldman Sachs, HSBC, KKR, KPMG, Morgan Stanley and UBS.

The one-day summit will focus on “business opportunities and leadership strategies for and within the LBGT community,” organizers said.

Secretary of State Hillary Clinton praised the group's work in a letter to attendees.

“The United States is committed to advancing the human rights of LGBT persons around the world, and through the Global Equality Fund that I launched on International Rights Day 2011, we are pursuing innovative models on collaborative, effective assistance to the LGBT community,” Clinton said, referring to the $3 million fund used to support groups working for gay, lesbian, bisexual and transgender rights worldwide.

“Forward thinking companies, such as those participating in Out on the Street, have often been at the forefront of positive change for LGBT people. I look forward to seeing the results of your efforts and to bringing more companies and governments together to make a global impact and produce real change in this important area.”

Paul Singer, founder of hedge-firm Elliot Management, and Lloyd Blankfein, chief executive officer of Goldman Sachs, were among the Wall Street leaders who discussed gay rights at the second annual Out on the Street summit held earlier this year in New York.
