Ullico delivered historic value for its shareholders in a successful and record-breaking 2021. Driven by our mission to support workers and their unions, we helped create union jobs, met the needs of union affiliates, provided investors with competitive returns, and did our part to be a positive force in local communities.
Our businesses thrived despite ongoing economic uncertainty caused by the COVID-19 pandemic. In fact, our adaptations and adjustments resulted in new products, skills and processes that have made the company stronger than ever.
Union Labor Life also maintained its leadership role in providing medical Stop Loss coverage to health and welfare funds. The Life & Health division achieved $20.9 million in new Stop Loss sales and retained 89% of its current business.
The Stop Loss international union dividend program allows health and welfare funds to receive dividends based on annual premium and/or claims experience. Since the program's inception in 2012 to the end of 2021, Union Labor Life has paid $32.7 million in dividends to participating health and welfare funds in these Stop Loss programs.
The supplemental insurance product lines, UnionCare, achieved $729K in new sales and continues to enhance its response distribution channels.
In 2021, Professional Liability program premiums reached a record $77.8 million, with 97% of policies renewing. The business unit also achieved a record number of insureds, with nearly 6,500 labor organizations and benefit plans covered.
UCG continued to enhance the products it offers to the union marketplace. In 2021, it expanded its relationship with Markel American Insurance Company to add more Business Owners policies and increase its Professional Liability program capacity from $85 million to $100 million. It also rolled out a Non-Profit Labor and Management form, implemented a new underwriting system, and partnered with The Hagerty Group, LLC to insure union members' collector vehicles, motorcycles, and boats. Lastly, it developed its Construction Risk Services portfolio through broker NFP to insure signatory contractors' projects and offer surety bonds so new contractors may work with building trades unions and compete on projects.
Ullico's Investment Services division offers investment products and services specifically designed for the union marketplace and employee benefit plans. The division's signature real estate and infrastructure products offer investors the opportunity to earn appropriate risk-adjusted returns while promoting union job creation.
During calendar year 2021, Ullico's Investment Services division increased its assets under management (AUM) by approximately $1.2 billion to reach $8.4 billion.
Assets under management by Ullico's Investment Services Division reached a new high of $8.4 billion. Our flagship real estate investment vehicle J for Jobs continued its mission to generate competitive returns while also creating good, union jobs. Since 1977, the Real Estate Investment Group's financing of more than 500 projects, has created more than 677 million union work hours. And the Ullico Infrastructure Fund continued to grow, reaching $4.2 billion in investor commitments. UIF aims to provide competitive returns while creating union jobs and stimulating economic growth in communities around the nation.
Likewise, our insurance businesses reached new highs, with Ullico's Life and Health Division reaching a record amount of gross written premium as our Property and Casualty division achieved a record level of program premium. Our group life policies now serve 1.2 million union members, and we have built a foundation to provide a menu of insurance services directly to union members with our UnionCare affiliate. Our Stop Loss insurance product continues to support union-affiliated funds by reimbursing millions of dollars in high cost medical claims. In addition to those reimbursements, for those plans that participate in our Stop Loss dividend program through their International Union, we returned millions of dollars in dividends. And our property and casualty products generated record premiums while serving 6,486 labor organizations and benefit plans, providing needed professional liability coverage for plan trustees and union leaders.
But the bottom line contains much more. After all, we are Ullico, not Wall Street. We strive to have a positive impact on people in communities across the country and beyond. In 2021, we continued to build a communications infrastructure to effectively spread the mission and message of Ullico and the union movement to a broader audience. We continued our proud tradition of supporting causes ranging from workers who are striking and organizing for better lives, to helping Ukrainian refugees, to providing educational and civic opportunities for those who might not otherwise have those doors open to them. As a company, we strive to be a leader in providing employment opportunities that reflect our nation and our movement, seeking the talent and insight of women, minorities and people of diverse backgrounds.
Last year with the COVID-19 pandemic raging, we were proud to say Ullico never lost its footing. This year, we can see the fruits of having adapted and adjusted, and out of hardship we have honed new products, new skills and new tools that have made our company even stronger.
We look to an even brighter future. When it comes to driving our mission and delivering value, the best is yet to come.
