Lloyd's has completed its transfer of more than $5bn (£3.5bn) to its two major US trust funds.
The money was raised by syndicates' cash calls to pay for World Trade Centre claims. The first tranche of the transfer took place in November 2001 when more than $2bn (£1.4bn) was moved.
A Lloyd's statement said: "A substantial element of the transfer was necessary to meet US regulatory requirements relating to insurance claims arising from 11 September, in respect of both direct business and US-ceded reinsurance business."
It said, to date, Lloyd's had received over 3,200 claims related to the World Trade Centre tragedy and is continuing to pay claims.
