Paragon has provided environmental site assessment and due diligence in accordance with American Society for Testing and Materials (ASTM) standards, All Appropriate Inquiry (AAI) requirements, and client-specific requests for sites across the United States, Canada, and numerous international sites. The purpose of a Phase I Environmental Site Assessment (ESA) is to gather information to develop a professional opinion about the environmental condition of the site and to identify actual or potential environmental contamination, which may impact the property value or affect claim to an “innocent land owner” exemption following an acquisition. Based on the findings, Paragon attempts to help the client resolve outstanding issues in a cost- and time-effective manner.

Mergers & Acquisitions (M&A)
Due Diligence
property acquisition

A significant part of Paragon’s practice since Paragon’s founding in 1997 is related to being part of due diligence teams for private equity clients. Typical services include Phase I environmental site assessments; Phase II environmental site assessments (soil and water sampling); regulatory compliance assessments; environmental database reviews (sometimes referred to as “desktop reviews”); peer reviews of target engineering firms; bracketing possible environmental exposure; assisting with establishing escrow amounts and requirements; interfacing with deal team legal counsel on diligence issues and contract language; development of post-closing plans; and a variety of other services as needed by a particular investment opportunity. Paragon prides itself on being able to customize scopes of services to the identified risks associated with a particular target platform company or add-on company. Exit or liquidity event support is also part of Paragon’s services and due diligence services are performed with an eye on the inevitable future exit from an investment. One particularly telling compliment received several times over the years is that Paragon helps to get the deal to closing by finding solutions to identified risks rather than just identifying the risk. Paragon has supported acquisitions of companies located in the United States, Canada, Mexico, the Caribbean, Brazil, China, Singapore, United Kingdom, Ireland, and other countries in Europe and Asia.

Risk-Based Evaluationrisk communication graphic

Risk assessment, properly applied, provides a practical and reasonable method of considering limited resources in the private and public sectors while being protective of human health and the environment. Paragon’s risk-based evaluation services pursue balanced decision-making based on scientific method. Paragon’s evaluations do not seek to identify and remove all uncertainty, but are planned to expeditiously and cost-effectively gather sufficient information to support an informed risk management decision. Paragon closely follows the American Society of Testing and Materials (ASTM) E50 committees developing new standards for risk-based evaluation. The company provides a diverse and innovative program of services scaled to the client and site needs, whether it be a Superfund-Level evaluation or Risk-Based Corrective Action (RBCA) for underground storage tanks. Paragon continues to actively monitor numerous state programs to implement RBCA, solid waste, Brownfields, and other risk-based initiatives.
