Lloyd 's then instituted some major structural changes : corporate members with limited liability were permitted to join and underwrite insurance ; no new unlimited-liability Names were allowed to join ( although a few hundred existing ones remained ) ; financial requirements for underwriting were changed , to prevent excess underwriting that was not backed by liquid assets ; and market oversight significantly increased . Lloyd 's rebounded and started to thrive again after the catastrophic losses arising out of the World Trade Center attack , but it faced increased competition from newly-created companies in Bermuda and other markets
