Jack Siebers is most commonly thought of as a business lawyer, although his resume and client list quickly reveal his expertise in the health care, insurance industry services and real estate acquisitions and development.

His extensive business experience was gained during his 15 years as vice president, general counsel and secretary of Foremost Corporation of America in Grand Rapids. At the time, Foremost was the parent corporation of Foremost Insurance Company and their stock was publicly traded on the NASDAQ market. In 1985, Jack entered practice as a partner with Dykema Gossett. In 1988, he formed his own firm and specialized in business and real estate law which continued until he joined Foster Swift.

Jack's work is that of a problem-solver. His practice includes:

  • Business & Corporation Law.  Jack counsels individuals and businesses with planning, formation, financing, licensing and periodic corporate reorganizations, including ongoing operational matters such as shareholder agreements, executive hiring and compensation, non-competition agreements and contracts with customers and suppliers.  In so doing, much of his time is spent as a proactive, problem solver.
  • Business Finance.  Jack advises businesses in finance transactions with investors and lenders, including publicly traded securities, private offerings, venture capital and taxable and tax exempt bond transactions.  The clients have included corporations, limited liability companies, limited partnerships, tax exempt organizations, finance companies, a bank and insurance companies.
  • Mergers & Acquisitions. Largely because he strives to be a "deal closer,” Jack has an active practice assisting buyers, sellers and business brokers in guiding them through the transaction steps from the confidentiality agreement, letter of intent, definitive purchase agreement, financing and closing. Transactions have entailed SBA loans and seller financing.
  • Corporate Governance. Having served as the corporate secretary of Foremost Insurance Company and its parent holding company, whose stock was publicly traded, Jack was keenly involved in all corporate governance matters for the company, including audit and other board committees. He served on the board and on the Governance Committee of Fremont Michigan InsuraCorp, whose stock was also publicly traded.
  • Family Businesses.  He regularly counsels family businesses with strategic planning, succession planning and the social dynamics involved with family members engaged in the operation of the business and those who are not.
  • Health Care and Tax Exempt Organizations.  Jack represents Michigan's largest nonprofit continuing care organization, a rehabilitation hospital, hospices and home care providers.
  • Real Estate.  The practice includes purchase, sale, development, leasing and management of properties, including business and residential condominiums.

Representative Matters

  • In addition to corporations in a variety of businesses, Jack has incorporated a number of insurance companies and assisted with their licensing in many states.
  • Fremont Mutual Insurance Co. retained Jack to convert it to a stock company, which became Fremont Insurance Company.  He represented the company in the sale of surplus notes to raise capital and later, through its holding company, in its initial public offering of its stock. In 2010, he advised the company in fending off a hostile takeover attempt, which included the successful enactment of a special state law aimed at preserving the company's independence. In 2011, he represented the company in its non-hostile sale to Auto Club Insurance Association for $70 million.
  • Since 1998, Jack has served as borrower's counsel to a health care organization in the issuance of $160 million of initial and refunding tax exempt bonds, including the issuance of $50 million in 2012.
  • In 2011, a bank retained Jack to represent it in providing a $23 million finance facility, which included an SBA loan for $5 million and a USDA loan for $5 million and collateral in various locations within and outside of Michigan.
  • Jack has advised a corporate borrower with a dozen interest rate swap derivative transactions with Lehman Brothers (including guiding the client through the Lehman bankruptcy), Morgan Stanley, Wachovia Bank and Wells Fargo Bank.
  • A nonprofit hospital retained Jack to design and implement a corporate reorganization that took it from a single hospital entity to a modern structure involving a tax exempt parent corporation, a foundation and several specialty tax exempt health care provider corporations.
  • A family business retained Jack to assist it with a charitable contribution of an S corporation to a public foundation.  Immediately prior to the contribution transaction, the owner made a non-qualified transfer of stock resulting in the deliberate loss of its S corporation status so as to allow the contribution.
  • Jack represented the owner of 200 acres of land in developing Centennial Office Park in Grand Rapids.  The park includes over a dozen office buildings, a hotel, an athletic club, four residential condominium developments and a golf course.
  • A group of physicians retained Jack to represent them in the acquisition, zoning, financing, syndication, construction, leasing and ultimate sale of a medical office complex which was sold for $23 million.
  • A manufacturer of specialty trucks engaged Jack to represent it in the acquisition of two manufacturing plants in other states.
