To our shareholders:
In 2011, the goals we set forth for Associated Banc-Corp were attained. Earnings increased each quarter. The credit quality of our loan portfolio continued to improve. Our loans outstanding increased substantially, with balanced growth across the major categories. Associated’s credit ratings improved and our capital levels remain very strong. We successfully repaid our TARP funds in September, without raising additional common equity. We dedicated ourselves to a renewed customer-centric focus. We celebrated 150 years of serving our communities this past year, and we reflect on this long history as we work to ensure continued growth in 2012 and beyond.
Delivering on Our Commitment to Shareholders
We set out in 2011 with a few specific goals, including:
• Returning the company to sustained and growing profitability – We achieved four consecutive quarters of growing profitability and delivered full-year net income available to common shareholders of $115 million.
• Repaying TARP funds in an efficient and shareholder-friendly manner and addressing open regulatory matters – In April and September, we repaid TARP funds without raising additional common equity and the OCC
Memorandum of Understanding (MOU) was terminated.
• Growing the loan portfolio throughout 2011 – We grew loans and gained market share throughout the year; total loans grew 11% year-over-year, and commercial and business loans grew 17% year-over-year.
As we look back, we are proud of having delivered on each of these commitments during 2011.
We also set out to grow our core businesses within our markets and to expand into new markets. We are pleased by our accomplishments on these fronts. We continued to enhance the customer experience by making investments in our people, our infrastructure and our facilities. Our performance this year was supported by strong loan growth across many of our portfolios, resulting from increases in both the number and depth of customer relationships. We also benefited from a strong credit recovery in all of our portfolios. This performance was achieved in spite of revenue headwinds, including the current low interest rate environment, as well as increased regulation from the implementation of the Dodd-Frank legislation.
Delivering on Our Strategy
Our Commercial Bank continues to be successful across all of our major markets. During the year, we added over 60 commercial lenders and grew commercial and business loans strongly over the prior year. In 2011, we promoted Donna Smith to lead the Commercial Banking group.
Commercial Deposit and Treasury Management, Specialized Industries and Commercial Financial Services have now all been aligned under the leadership of John Utz. John has a broad background in specialized commercial lending and treasury management and is leading the charge on our efforts to grow commercial deposits.
Our Commercial Real Estate business, under the leadership of Breck Hanson, continues to provide us with numerous opportunities to work with seasoned and experienced developers. During the past year, we have expanded this business to new markets, including Cincinnati and Indianapolis, by bringing on board seasoned real estate lending teams with local experience. In 2012, we will further expand our Commercial Real Estate business into Michigan.
We have continued to invest in our Retail Bank under the leadership of David Stein. During 2011, we launched a multi-year project to improve customer experience in our branches, with more than 30 relocated, remodeled or new offices and new signage in most locations. Our plans for 2012 include remodeling another 50 branches, while at the same time consolidating more than 20 branches into other nearby locations. We have enhanced product offerings and elevated service levels for our Premier Banking clientele. In addition, we have made major

enhancements to our mobile banking and online banking platforms for all customers. We remain the number one mortgage lender and Small Business Administration lender in Wisconsin.
We continue to be pleased with the success of our Private Banking, Trust and Asset Management efforts. During the year, we strengthened this team with key hires in Milwaukee and more recently in Minneapolis. We appreciate and thank our recently retired Vice Chairman, Mark McMullen, for his many years of leadership in this area and are pleased that the group has continued to thrive with Tim Lau as its new leader.
During the course of the year, we also added key talent to our support teams. Arthur Heise joined the company as Chief Risk Officer to facilitate our work toward navigating the increased compliance and risk management demands of the industry. Patrick Derpinghaus joined the company and assumed the position of Chief Audit Executive, following the retirement of Art Olsen.
In July, we welcomed John (Jay) B. Williams to the Board. Jay currently serves as the President and CEO of the Milwaukee Public Museum, following a 37-year career in commercial banking in Wisconsin and Chicago, and brings a wealth of banking experience to our Board.
Delivering Value for Communities
Over the course of the year, our colleagues continued to show dedication to our local communities and combined to volunteer over 13,000 hours of service to nonprofit groups throughout
all of our markets. Additionally, this year we are proud to have raised over $1 million for United Way chapters through our annual workplace giving campaign.
Delivering Value for Customers
Early in 2010, we launched our Vision and Values statement that set the foundation for how we approach our business. We have recently launched our Customer Promise that builds on our Vision and Values by making a commitment to our customers of what they can expect from Associated in everyday interactions. We have included a copy of our Customer Promise on the following page of the annual report.
Delivering Value for Shareholders
We believe that by delivering for our customers and communities we can drive value for our shareholders over time. We are pleased to have delivered improving results for our shareholders over the course of this year and are proud to have recently announced an increase to our common dividend. Despite the challenging environment, we remain optimistic and are committed to building shareholder value through our long-term strategy for growth at Associated.
Thank you for your continued support of Associated Banc-Corp.
