For the quarter period ended 30 June 2012, its earnings per common share was $0.98, 2% down from $1 in the second quarter of 2011 and up by 15% from $0.85 in the first quarter of 2012.

Return on average common shareholders’ equity was 10.0% in the second quarter of 2012, against 10.6% in the second quarter of 2011 and 8.8% in the first quarter of 2012.

State Street’s chairman, president and chief executive officer Joseph Hooley said, "The global economic environment remains challenging and so we are focused on controlling what we can: delivering value-added solutions to our clients, executing on our business operations and information technology transformation program and continuing to manage expenses."

Net after-tax unrealized mark-to-market losses in the investment portfolio were $54m, an improvement from net unrealized mark-to-market losses of $81m from the first quarter of 2012, backed by the benefit of lower rates, offset partially by the impact of wider spreads.
