On February 6, 2004, we submitted a certified contract claim to the United States requesting contractual indemnity for remediation and litigation costs (past and future) related to our former facility in Redlands, California.
We submitted the claim consistent with a claim sponsorship agreement with The Boeing Company (Boeing), executed in 2001, in Boeing’s role as the prime contractor on the Short Range Attack Missile (SRAM) program.
The contract for the SRAM program, which formed a significant portion of our work at the Redlands facility, had special contractual indemnities from the U. S.  Air Force, as authorized by Public Law 85-804.
On August 31, 2004, the United States denied the claim.
Our appeal of that decision is pending with the Armed Services Board of Contract Appeals.

In order to reduce earnings volatility from foreign currency exchange rate movements, we enter into forward currency derivative contracts to effectively fix the currency exchange rates for a portion of our prospective non-USD-denominated earnings streams.
This forward currency hedging program is primarily associated with our insurance operations in Japan and Korea.
In order to reduce equity volatility from foreign currency exchange rate movements, we primarily utilize a yen hedging strategy that calibrates the hedge level to preserve the relative contribution of our yen-based business to the Company’s overall return on equity on a leverage neutral basis.
We implement this hedging strategy utilizing a variety of instruments, including USD-denominated assets, foreign currency derivative contracts, and dual currency and synthetic dual currency investments held locally in our Japanese insurance subsidiaries.
The total hedge level may vary based on our periodic assessment of the relative contribution of our yen-based business to the Company’s overall return on equity.
The table below presents the aggregate amount of instruments that serve to hedge the impact of foreign currency exchange movements on our USD-equivalent shareholder return on equity from our Japanese insurance subsidiaries as of the dates indicated.
