SKW Schwarz has long-standing experience in legally designing important strategic decisions.

We advise companies of all sizes, whether corporations or partnerships, including medium-sized, often family-owned, businesses in all fields of corporate law. Primarily, this includes:

  • Advice on organizational structure (corporate governance)
  • Contractual agreements with executive bodies (general managers, members of executive, supervisory, and advisory boards)
  • D&O liability
  • Equity and debt financing (capital increases, shareholder loans)
  • Cash pools
  • Preparing and holding of shareholder and general meetings
  • Group law
  • Transactions under reorganization law (mergers, spin-offs, change of legal form)
  • Joint ventures and strategic partnerships
  • Matters of capital market law and restructuring

In addition, we advise our clients on all corporate compliance issues (preventive advice, including by drafting guidelines and training materials, and advice on handling compliance violations).

Our work also focuses on representing clients in disputes, both before ordinary courts and in arbitral proceedings, for example in shareholder disputes or shareholder actions.

He also advises on other transactional matters such as sector-specific permit requirements as they often arise in regulated industries.

Mr. Grünwald also counsels his clients on a wide range of operational issues, for example on abuse of dominance issues, information exchange, vertical agreements, antitrust compliance, and internal investigations. Moreover, his practice includes antitrust litigation, specifically with regard to cartel damage claims, where he represents clients in German courts and advises on the application of German law in relation to cross-border cartels.

Firm Overview:

Morrison & Foerster is a firm of exceptional credentials. Our name is synonymous with a commitment to client service that informs everything that we do. We are recognized throughout the world as a leader in providing cutting-edge legal advice on matters that are redefining practices and industries.

But the Morrison & Foerster name tells only part of our story. In the 1970s, when teletype was used to send overseas cables, the firm purposely chose “mofo” as our teletype address. The nickname stuck, and we later decided to use it as our domain name.

In many ways, the MoFo nickname is an affectionate reminder that while we are very serious about our clients’ work, we don’t take ourselves too seriously.

We collaborate across a global network of 16 offices located in key technology and financial centers in the United States, Asia, and Europe. Our clients include some of the largest financial institutions, Fortune 100 companies, and leading technology and life sciences companies. We also represent investment funds and startup companies, and over the years have supported many in their growth and development as leading industry players and household brands.

Morrison & Foerster stands out for its commitment to client service. The BTI Consulting Group’s Client Relationship Scorecard regularly includes us on its prestigious list of “Power Elite” law firms, based on the results of interviews with general counsel and other decision-makers at more than 500 leading companies.

Firm Overview

Five decades ago, while at lunch in a South Florida deli, attorneys Mel Greenberg, Robert Traurig, and Larry J. Hoffman, saw an opportunity to establish a new breed of law firm for South Florida; one that mirrored a New York style firm. In 1967, they founded the law firm Greenberg Traurig Hoffman, a quality business law firm where client service and collaboration ruled.

This new model was strong and scalable: deliver the quality of legal work to which substantial U.S. commercial clients were accustomed; truly listen to and work hand-in-hand with clients to help them achieve their goals (not simply drown them in legalese); and do so while offering a decentralized structure that would help them control their legal costs. This approach would also allow the new firm to develop substantial and long-term relationships with some of the top businesses in the region and, eventually, the world.

In the early 1990s, the consolidation of firms had started to take off. The firm developed and executed a strategy that would allow it to deliver the United States to clients at much better value through quality lawyers in the key growth, financial, and political centers in the United States. Clients no longer needed to hire two different firms for the same matter. Because matters were priced locally and with flexibility, they could take advantage of market differences when it came to budgeting.

The firm’s cultural strategy attracted the highly ranked attorneys, who were already perceived as leaders in their community. These individuals wanted to join a firm of positive people who valued working together and shared experience and clients for the benefit of all involved.

The new firm was (and remains) non-bureaucratic. When clients needed a decision, they knew they were talking to someone who could make it happen.

From the beginning, Greenberg Traurig selected laterals not solely on traditional criteria, but also on how well they fit this new culture of collaboration. Additionally, the firm focused on creating a business staff roster that aimed to be the best in the profession.

Early on, Greenberg Traurig developed a strong commitment to giving back to the community. Attorneys and business staff striving to make a difference by leading, volunteering, and donating to a rich spectrum of causes.

Fifty years after its founding, Greenberg Traurig has more than 2,000 attorneys and 38 locations on three continents.

As each new office opened, this unique culture was replicated, but never dictated. The firm grew by way of laterals who fit in and had a passion for quality work and collaboration, and in response to client needs. Greenberg Traurig has never added lawyers through a merger and remains one firm. Each new office can be traced to an opportunity to better serve clients.

There never has been a headquarters office. From Day 1, people have been empowered to do the right thing and the best thing no matter where they were sitting. These qualities have allowed the firm to thrive along with its valued clients, attorneys, and staff.

We are proud of our achievements and grateful to our founders and to all those who continuously work harder and smarter to expand their vision.
