Outpacing the growth in premiums, LLAE rose $6.4 billion, or 8.6 percent, to $80.8 billion in first-quarter 2014 from $74.4 billion in first-quarter 2013.
Increases in both catastrophe and non-catastrophe losses contributed to the upward surge in overall LLAE. ISO estimates that private U.S.
insurers' net LLAE from catastrophe includes their losses from all catastrophes, whether they struck the United States or elsewhere around the globe.
Net LLAE (after reinsurance recoveries) dropped $20.2 billion, or 7.7 percent, to $243.9 billion in nine-months 2012 from $264.1 billion in nine-months 2011.
Partially negating the effects of the growth in premiums and decline in LLAE, other underwriting expenses--primarily acquisition expenses; expenses associated with underwriting, pricing, and servicing insurance policies; and premium taxes increased $3.3 billion, or 3.5 percent, to $96.9 billion in nine-months 2012 from $93.6 billion in nine-months 2011.
The decrease in overall LLAE was largely driven by the decline in catastrophe losses, with ISO estimating that private insurers' net LLAE from catastrophes fell $18.4 billion to $16.7 billion in nine-months 2012 from $35.1 billion in nine-months 2011.
"ISO estimates that insurers' combined ratio would have risen 1.3 percentage points to 103 percent in first-half 2011 if net LLAE from catastrophes had remained the same as they were in first-half 2010.
Net losses on underwriting grew $19 billion to $24.1 billion in first-half 2011 from $5.1 billion in first-half 2010, as growth in LLAE and other underwriting expenses outpaced growth in premiums earned.
Net LLAE (after reinsurance recoveries) rose $21.7 billion, or 14.2 percent, to $174.2 billion in first-half 2011 from $152.5 billion in first-half 2010.
Net LLAE (after reinsurance recoveries) rose $2.8 billion, or 0.9 percent, to $309.1 billion in 2010 from $306.3 billion in 2009, largely as a result of higher catastrophe LLAE.
ISO estimates that private insurers' net LLAE from catastrophes striking the United States rose $2.7 billion to $14.3 billion for 2010 from $11.6 billion for 2009, with the $11.6 billion for 2009 including some late-emerging losses from Hurricane Ike in 2008.
Noncatastrophe net LLAE rose $0.1 billion to $294.8 billion for 2010 from $294.7 billion for 2009.
