With borrowing costs at their lowest levels since 2004, reinsurers are loading up on corporate debt in part to fund stock buybacks. The latest tally, according to Bloomberg News, is $1.34 billion in additional borrowing, with Endurance Specialty Holdings (ENH), a Bermuda-based company, recently selling $85 million in bonds. Other recent transactions include Axis Capital Holdings (AXS) and PartnerRe (PRE) each issuing $500 million in bonds and RenaissanceRe (RNR) adding $250 million to the count.

Catastrophe modelers, insurers and reinsurers are still sorting out the damage from Windstorm Xynthia in Europe and the earthquake in Chile. Taking only the highest of high-end estimates, the damage from these two catastrophes could exceed $12 billion, resulting in fairly steep property-catastrophe losses long before hurricane season begins. With three more major property reinsurance renewals remaining for the year -- at April 1, June 1 (Florida) and July 1 -- there is plenty of time for the impact of these events to be absorbed into reinsurance pricing.
