About Big4News

Big4News is an independent publication edited by Claudine Cassar that focuses on Deloitte, PwC, EY, and KPMG.

Each week, it cuts through the noise to give readers a clear, big-picture view of the issues that actually shape 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 aim is straightforward: to help professionals, students, job seekers, regulators, journalists, investors, and anyone interested in these firms understand what’s happening, why it matters, and what it reveals about the world’s most influential professional services networks.

About The Editor

Claudine Cassar is a former Deloitte equity partner who led the firm’s consulting practice in Malta after selling her technology business to Deloitte in 2016.

Her background in anthropology, journalism, entrepreneurship, and Big Four leadership shapes how Big4News looks at these firms — not just through financials and deals, but through culture, incentives, governance, and accountability. She now writes independently and has no ongoing affiliation with any of the Big Four firms.

Editorial Approach

Big4News is completely independent. It does not accept sponsorship, advertising, or any form of payment from Deloitte, PwC, EY, KPMG, or from anyone seeking to influence its coverage.

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

Analysis is clearly separated from reported facts. Corrections, clarifications, story suggestions, and additional context are always welcome at big4news@claudinecassar.com.

Guest Contributions & Expert Voices

Big4News welcomes thoughtful contributions from experts, academics, regulators, former insiders, and practitioners with deep experience in auditing, consulting, governance, regulation, or professional services.

Submissions are reviewed for relevance, factual accuracy, and editorial standards. All guest content is clearly labelled and edited for clarity while preserving the contributor’s independent voice and perspective.

AI Use and Editorial Responsibility

Big4News uses artificial-intelligence tools to assist with research and production. These tools may be used to review large volumes of public material, organise timelines, summarise documents, check structure, improve clarity, and support the creation of featured images and other editorial illustrations.

Some images published by Big4News are created or adapted using generative AI. Unless expressly stated otherwise, these images are illustrative and should not be understood as photographs of actual events, locations or documents.

Editorial responsibility remains with the editor. Claudine Cassar selects the stories, conducts the analysis and interpretation, determines the conclusions, and completes the final editing. She reviews factual claims against the original source material before publication and is responsible for the accuracy, fairness and presentation of the published work.

Corrections, clarifications and additional context from readers are always welcome.
