The Tax Law Practice

In recent years, following the passage of the Sarbanes-Oxley Act and changes in stock exchange listing requirements, companies and their directors have recognized more than ever the importance of having solid corporate governance practices in place within their organizations. Our corporate governance practice combines the expertise of lawyers from our corporate, employment, securities, tax and litigation practices in order to provide practical advice and solutions with respect to a multitude of corporate governance issues ranging from routine compliance issues to proxy contests and board investigations.

Our attorneys have extensive experience in advising public companies on the corporate governance requirements of the Sarbanes-Oxley Act as well as complex regulations and rules adopted by the Securities and Exchange Commission, the New York Stock Exchange and NASDAQ. Our lawyers have advised public companies, boards of directors and special committees of directors about their fiduciary duties and other corporate governance matters related to merger and acquisition transactions, conflict of interest transactions, leveraged buyouts, corporate compensation, governmental and regulatory inquiries, claims by whistleblowers and CEO and CFO certifications with respect to financial statements in public company reports.

Additionally, we have expertise representing committees tasked to investigate claims of corporate wrongdoing and financial misrepresentation, including backdating of options, to investigate shareholder allegations raised in derivative litigation and to investigate the fairness of proposed corporate transactions.

Rogers & Hardin

Rogers & Hardin is the Atlanta-based law firm with a national reputation for excellence. We’ve been helping clients solve challenging legal problems for 40 years. Many clients comment that our approach is unique. Key differences are:

Most of our partners are recognized for excellence by one or more of the leading national ranking services. Other firms have ranked partners too. The Rogers & Hardin difference is that these nationally recognized partners are hands on working directly on client matters. Their skill brings efficiency and excellence to our work product. Efficiency translates into fewer hours expended and less supervision required for our clients. Clients notice and appreciate both.

Our service delivery model differs from many of our peers. We maintain a lean staff-to-attorney ratio in order to give clients direct access to our partners, who have rates that are often significantly lower than their peers. This approach adds tremendous value for our clients.

We measure success differently than other firms. We focus on client satisfaction, responsiveness and exceeding expectations. For clients who have experience working with legal teams that only think about them when the meter’s running it is a noticeable difference.

Sustaining excellence across both disciplines within our footprint is challenging to say the least. Yet the benefits it delivers to clients are immense. Rogers & Hardin is the only firm in the Southeast recognized for excellence across such diversity in practice coverage outside of a Big Law platform. Clients appreciate having that choice.

Our firm is skilled at all phases of dispute resolution including trying cases in front of the federal, state and local bars. We are often the firm engaged by other law firms when they need trial counsel support. Clients find that having a firm with a successful reputation as a strong trial adversary gives them more flexibility in resolving disputes.

Rogers & Hardin is an active member of Interlaw, the international network of pre-vetted, annually reviewed, full service law firms with nearly 5,000 attorneys in more than 125 cities worldwide. This gives our clients direct access to a global of network of law firms on a preferred fee scale no matter where their business takes them.
