Whenever I attempt to explain Rockland Trust’s sustained organizational success, one of my favorite engineering images always comes to mind—a flywheel, a mechanical device designed to store energy and maintain momentum. During my time at Rockland Trust, my interest in how things work has helped me to reflect on the influence that our four key constituencies—colleagues, custom- ers, communities, and shareholders—have on each other. While there are many reasons why Rockland Trust has prospered, our Cycle of Engagement, illus- trated above, is the reinforcing loop of our success. Acting as our corporate flywheel, it has been set in motion with care and has been essential to our steady growth over the years: ENGAGED COLLEAGUES: Our process starts with colleagues, who consistently deliver focused, value- added products and services to our customers in a frictionless, easy-to-do-business-with manner; ENGAGED CUSTOMERS: The efforts of my engaged colleagues forge strong relationships with an increasing number of engaged, loyal customers, which is why Rockland Trust is known as the place Where Each Relationship Matters®; HIGH PERFORMANCE: The relationships between engaged colleagues and engaged customers lead to strong financial performance as reflected by five con- secutive years of record-setting operating earnings; INVESTMENT: Our financial results permit us to provide superior returns to our shareholders and reinvest in our colleagues, communities, and long-term initia- tives that improve the value our customers receive. Independent Bank Corp. | 2017 Annual Report 1 The Boston Globe named Rockland Trust a Top Place to Work, the top-ranked financial services firm in our category and the second-ranked company overall. We endeavor to foster a great place to work in a variety of ways. We provide mentoring opportunities for col- leagues and a strong coaching culture with programs that enhance leadership, professional, and workplace skills. Our employee resource groups support diversity and inclusion, women, and the LGBTQ community. Our award-winning RockFIT program promotes physical, emotional, and financial wellness of our colleagues. In addition, we encourage volunteerism through RockCorp, which matches our employees with non- profit organizations in need of help. We also have a wide variety of employee reward and recognition opportunities, including our Shining Stars and You Make A Difference peer recognition program. Further, learning opportunities are offered through many on-site training opportunities and tuition assistance for students seeking certificates, and Associate, Bachelor’s, and Master’s degrees. The Human Rights Campaign Named Rockland Trust a Best Place to Work for the LGBTQ community for the third year in a row. It all starts with my colleagues who are responsible for the good things that happen here at Rockland Trust. Our long-term sustainability begins with creat- ing a great place to work because that is how we attract and retain great people. We cannot be a great place to bank unless we are, first and foremost, also a great place to work. The Rockland Trust corporate culture engages my colleagues at the deepest level and is founded upon a commitment to caring and respecting relationships, exemplary service, and teamwork. The importance we place on lifelong learning, curiosity, and continuous improvement is reflected in a picture prominently displayed on my office wall. It holds 15 years of class photos for our Rockland Trust Scholars, colleagues who have earned a degree or certificate during the prior year. It now represents more than 355 scholars and 364 certificates and degrees. There are so many scholars that I had to add a second picture frame a couple of years ago. 2 Bank Director ranked Rockland Trust the #1 performing bank in Massachusetts in their annual Bank Performance Scorecard. J.D. Power awarded Rockland Trust the “Highest Customer Satisfaction with Retail Banking in New England” for the second time in five years. Respected third parties noticed our high levels of colleague and customer engagement in 2017: Rockland Trust was thrilled to receive J.D. Power’s top ranking for “Highest Customer Satisfaction with Retail Banking in New England.” The Boston Globe, for the ninth consecutive year, named Rockland Trust a Top Place to Work. We were the top-ranked financial services firm in our category and the second-ranked company overall on the list. The Human Rights Campaign also recognized us by naming Rockland Trust a Best Place to Work for the LGBTQ community for the third year in a row. These accolades reflect our Cycle of Engagement: investing in colleagues creates an engaged work- force, which creates engaged customers. Since our customers are engaged with the brand, they reward us with more of their business and recommend us to their friends. These enduring relationships with our customers create success, and the connections moti- vate my colleagues to invest their energy and passion back into Rockland Trust and the communities in which my colleagues and our customers work and live. Ongoing learning is a valuable contributor to this cycle because each time one colleague advances, Rockland Trust also improves. A continual search for learning and knowledge is a key part of each colleague’s journey at Rockland Trust. Rockland Trust’s successful journey is the collective result of these individual journeys. There are many examples among long-time colleagues, our newest employees, and those who have joined Rockland Trust from other banks or organizations, whether through bank acquisitions or recruitment. Gerry Nadeau, who is currently the President of Rockland Trust, is a prime example of a long-time colleague who has thrived and grown throughout his 35-year career. Gerry’s Rockland Trust journey began Independent Bank Corp. | 2017 Annual Report 3 Rockland Trust and introduces new colleagues to our brand and corporate culture. For colleagues who join by way of an acquisition, we customize our approach starting from the day of announcement. As we look ahead to the next 100 years, I am confi- dent that our focus on building a great place to work positions us to take advantage of the opportunities before us and manage through the challenges that will arise. This approach has withstood the test of time and has led to the healthy growth in our Company’s earnings, stock valuation, and tangible book value. Rockland Trust’s future is tied to the future of each of our colleagues and those of our customers, commu- nities, and shareholders. The story we tell collectively will be our story for the next 100 years. I am excited to embark on the next stage of that journey with you. Thank you for your support and continued trust, Christopher Oddleifson President and Chief Executive Officer Independent Bank Corp. and Chief Executive Officer Rockland Trust Company in 1984 as a management trainee, during which he experienced all roles including time on the teller line. In 1992, Gerry was named a Senior Vice President of Commercial Lending and ran our Brockton Lending Center for many years, working with many of our largest customers. In 2007, Gerry became the leader of the Commercial Banking Division and, during 2017, Gerry was appointed as President of Rockland Trust and joined me on our Board of Directors. Maria Harris, Rockland Trust’s Director of Human Resources, is another example. After working in retail management and corporate recruiting at the start of her career, Maria joined us in 2004 as a recruiter. Since then Maria has seen the number of our colleagues double and our assets grow by nearly three times. Working with leaders across the Bank, Maria created RockFIT and also led the effort to form the Diversity Council to expand our understanding and appreciation of diversity in the workplace and business opportuni- ties in the marketplace. Soon afterwards, Maria guided colleagues to form their own Employee Resource Groups, such as Women of Action, the Inclusion Network, and the Pride Alliance. Gerry and Maria are two examples of the thousands of journeys taken by our colleagues. There are many others, such as the talented colleagues in our Rising Stars career development program that helps prepare and promote the next generation of leaders. We also welcome and embrace those who join our organiza- tion by providing a Strategic Orientation session to all new employees that describes the rich history of 4 2017 Accolades Awarded the “Highest Customer Satisfaction with Retail Banking in New England” according to the J.D.
