Да, похоже, это компания с ограниченной ответственностью (именно так расшифровывает эту абревиатуру Лингво 9.0).

Что касается flexible:

The limited liability company (\"LLC\") revolution was underway. Now all states and the District of Columbia have enacted LLC Acts to allow formation of these flexible new entities with the advantage of corporate like limited liability and the partnership tax treatment.

Since its Wyoming LLC ruling the Service has issued eighteen additional LLC Revenue Rulings, one \"clarification\" (26 CFR 301.7701-2(b)(1)) and two Rev Procs. (94-46 and 95-10), all clarifying and lowering the hurdles to be cleared for the LLC to be recognized for partnership tax treatment. The states have responded by adopting less restrictive \"flexible\" LLC Acts, narrowing considerably the traditional distinctions between corporations and partnerships.

Может, так и назвать - гибкая? Это явно не \"общего типа\".
