Firm History:

Founded by Marshall Skadden, Les Arps and John Slate on April Fools’ Day in 1948, Skadden began as a scrappy upstart among a sea of established “white shoe” law firms in New York. Joe Flom was hired as the firm’s first associate later that year, and litigator Bill Meagher, the fifth partner to lend his name to the firm’s letterhead as it appears today, joined in 1959.

Our first two decades were marked by slow and steady growth of our client base as we set out to establish ourselves as the go-to firm for our clients’ most complex legal problems. Our willingness to handle proxy fights in the 1950s and early 1960s — matters deemed “ungentlemanly” by white shoe firms — positioned us to ultimately become the firm of choice for the hostile takeovers that dominated the M&A landscape beginning in the 1970s.

Recognizing the value of providing full-service advice to clients, from day one we sought to develop a range of complementary practices, like litigation, tax and antitrust. Client needs led us to open offices in other cities beginning in 1973, and the volume of work we were handling fueled exponential growth in the number of attorneys at the firm in the 1980s. That growth included a significant expansion of the practices we offered to clients, including restructuring, finance, real estate, mass torts and securities litigation, as well as the opening of offices in Europe and Asia.

In the nearly three decades since, we’ve built on that platform to provide advice to clients around the world on their most important matters. Our core values reflect the ideals of our history, and we remain committed to providing excellent lawyering and unrivaled client service in all our work.

A&A Partners hold “Be of Good Use” as our guiding precept and we are expected to remember the precept whenever we decide something. We provide two main services, assurance services and advisory services, which are reflected in the name of our firm. Assurance services include audits for listed companies and audits under the Companies Act. Advisory services include such services as assisting in an initial public offering (IPO) and corporate valuation services, support for adoption of International Financial Reporting Standards (IFRS).

In assurance services, we recognize it is very important to understand clients. If we do not understand clients, we could not meet the requirement as the professional. We recognize quality as a matter of the highest priority. If our quality level were low, we would not be able to embody our guiding precept, “Be of Good Use,” and would cause great trouble for our clients.

We require our staff members to be highly skilled professionals. We hold or attend training course any time if necessary and acquire sufficient knowledge and skill required as professionals aiming to be of good use.

We use an electronic work-paper system developed in-house to secure the expected assurance level and improve the efficiency of our work. This enables us to provide high-quality audit services efficiently.

We establish the system which provides high-quality audit services at a reasonable cost by continuous investment in human resources and improvement of quality.

In regard to advisory services, we also recognize it is important to understand clients. We need to provide suitable services to our clients based on sufficient understanding of clients. We provide such wide-ranging services as M&A services, financial due diligence services, supporting IPOs, assisting IFRS adoption, and facilitating business restructuring.

Recently, the number of companies going public has been increasing. Therefore, we are actively expanding the services headed by our experienced partners in IPO services, more than 50 companies of success in the past.

With regard to IFRS, we recognize it is very important to understand clients. We provide suitable services to clients. To prepare for IFRS, usually companies are required to conduct large-scale of reforms in business process such as modification of IT systems. Piecemeal reforms might bring companies risk of wastefulness. We have established a structure in our firm to assist clients in making a smooth changeover to IFRS.

We believe that audit firms will become differentiated in the future respectively according to its field of expertise responding to clients’ such characters as industries, scale, globalization. In assurance services, we provide high-quality and efficient audit services mainly to small and medium-sized companies. In advisory services, we pledge to support the client’s business with tender attention and enough experience.

More and more companies might expand their business outside of Japan in the future. Regarding this circumstances, we joined Morison International, the global association of independent accounting and consulting firms extending over 60 countries. Furthermore, we made the alliance with Plante & Moran, the middle-sized accounting firm based in the United States. Morison International features the advantage of networks in Southeast Asian countries that Japanese companies recognize as significant market recently. We have also close relationships with tax accounting firms, law offices and other professionals. Under these relationships, we provide multipronged services to clients.
