Lord Hutton will today end his call for evidence to the public sector pensions inquiry after the close of a seven-week consultation.
It marks the nominal beginning of the commission's review of submissions, which will conclude with a final report in time for the 2011 budget.
An official at the Independent Public Service Pensions Commission said they were receiving information from a variety of sources and today was likely to be "very busy" as submissions came in.
The commission issued a call for more evidence on topics including appropriate scheme design and risk sharing following the publication of their interim report in October.
After the close of consultation today, Hutton and the rest of the commission will read the submitted evidence and meet with various stakeholders.
The original call for evidence generated 137 submissions from public sector worker groups, government departments, unions, consultants and individuals.
The latest call for evidence was comprised of 25 questions, including "What is an appropriate scheme design for public service pensions?" and "Which risks associated with pension saving should the scheme members bear, which by the employer and which should be shared?"
The review will look at schemes covering civil servants, teachers, NHS workers, the army, local government, police, firefighters and others.
The final report is scheduled for release on 23 March.
