Henderson Group
Henderson Group plc was a global investment management company with its principal place of business in the City of London. It merged with Janus Capital Group in May 2017 to create Janus Henderson. History
The Company was established in 1934 to administer the estates of Alexander Henderson, 1st Baron Faringdon. In 1975, it started managing pension funds. It was first listed on the London Stock Exchange in 1983. In March 1998, it was bought by AMP Limited (and subsequently integrated with AMP Asset Management's operations 
in the UK and Australasia as Henderson Global Investors.) On demerger from AMP and re-listing as HHG Group in 2003, the group comprised Henderson Global Investors (a UK-based investment manager), Life Services (comprising the life and pension books of Pearl Assurance, NPI, National Provident Life, London Life Association, and HHG Services) and the financial advisory firm, Towry Law. AMP Limited sold its remaining 15% stake in the Company in 2005. Between 2008 and 2012, the Group was tax-resident in the Republic of Ireland. With effect from 12 December 2012, the Group changed its tax residency from the Republic of Ireland to the UK by means of a corporate restructuring. In 2010, the company phased out the New Star name, and in 2014, the company rolled out a new brand identity. In May 2017, the company completed a merger with Janus Capital Group to form Janus Henderson. Acquisitions and sales
