About Big4News

Big4News is an independent publication by Claudine Cassar, a former Deloitte equity partner and corporate anthropologist, covering Deloitte, PwC, EY, and KPMG.

Each week, I give readers a clear, big-picture view of the issues shaping the Big Four: regulatory and litigation risk, AI transformation, talent and partnership pressures, global network tensions, reputational challenges, and the financial and operational realities behind the headlines.

The goal is simple: to help professionals, students, job seekers, regulators, journalists, investors, and anyone interested in the Big Four understand what is happening, why it matters, and what it reveals about the world’s most influential professional services networks.

About The Author

Claudine Cassar previously led Deloitte Malta’s Consulting practice after selling her technology business to the firm in 2016.

Her background in anthropology, journalism, entrepreneurship, and Big Four leadership shapes the way Big4News examines the culture, incentives, governance, and accountability of Deloitte, PwC, EY, and KPMG.

She now writes independently, with no ongoing affiliation to any of the Big Four firms.

Editorial Approach

Big4News is completely independent. I do not accept sponsorship, advertising, or payment from Deloitte, PwC, EY, KPMG, or from organisations seeking to influence Big4News coverage.

Stories are chosen because they are significant to the profession, the firms’ stakeholders, and the public interest. I draw on public records, regulatory filings, court documents, company reports, inspection findings, parliamentary and regulatory materials, media coverage, and conversations with people across the Big Four ecosystem.

When I offer analysis, I distinguish it from reported facts. Corrections, clarifications, story suggestions, and additional context are always welcome: big4news@claudinecassar.com.

AI Use and Editorial Responsibility

Big4News uses AI tools as part of the research and drafting process. These tools help with tasks such as reviewing large volumes of public material, organising timelines, summarising documents, checking structure, and improving clarity.

They do not replace editorial judgment. Story selection, analysis, interpretation, conclusions, and final edits are my own. I review factual claims against the underlying source material before publication and welcome corrections, clarifications, and additional context.

The aim is not to automate journalism, but to use technology responsibly to make complex Big Four developments more accessible, better organised, and easier to understand.
