4.   DERIVATIVES

The Company sold seven equity index put option contracts, based on two indices, in 2001 and 2005, which remain outstanding.  The Company sold these equity index put options as insurance products with the intent of achieving a profit.  These equity index put option contracts meet the definition of a derivative under FASB guidance and the Company's position in these equity index put option contracts is unhedged.  Accordingly, these equity index put option contracts are carried at fair value in the consolidated balance sheets with changes in fair value recorded in the consolidated statements of operations and comprehensive income (loss).

The Company sold six equity index put option contracts, based on the Standard & Poor's 500 ("S&P 500") index, for total consideration, net of commissions, of $22,530 thousand.  At March 31, 2014, fair value for these equity index put option contracts was $30,516 thousand.  These equity index put option contracts each have a single exercise date, with maturities ranging from 12 to 30 years and strike prices ranging from $1,141.21 to $1,540.63.  No amounts will be payable under these equity index put option contracts if the S&P 500 index is at, or above, the strike prices on the exercise dates, which fall between June 2017 and March 2031.  If the S&P 500 index is lower than the strike price on the applicable exercise date, the amount due would vary proportionately with the percentage by which the index is below the strike price.  Based on historical index volatilities and trends and the March 31, 2014 S&P 500 index value, the Company estimates the probability that each equity index put option contract of the S&P 500 index falling below the strike price on the exercise date to be less than 25%.  The theoretical maximum payouts under these six equity index put option contracts would occur if on each of the exercise dates the S&P 500 index value were zero.  At March 31, 2014, the present value of these theoretical maximum payouts using a 3% discount factor was $410,762 thousand.  Conversely, if the contracts had all expired on March 31, 2014, with the S&P index at $1,872.34, there would have been no settlement amount.

The Company sold one equity index put option contract based on the FTSE 100 index for total consideration, net of commissions, of $6,706 thousand.  At March 31, 2014, fair value for this equity index put option contract was $6,567 thousand.  This equity index put option contract has an exercise date of July 2020 and a strike price of £5,989.75.  No amount will be payable under this equity index put option contract if the FTSE 100 index is at, or above, the strike price on the exercise date.  If the FTSE 100 index is lower than the strike price on the exercise date, the amount due will vary proportionately with the percentage by which the index is below the strike price.  Based on historical index volatilities and trends and the March 31, 2014 FTSE 100 index value, the Company estimates the probability that the equity index put option contract of the FTSE 100 index will fall below the strike price on the exercise date to be less than 41%.  The theoretical maximum payout under the equity index put option contract would occur if on the exercise date the FTSE 100 index value was zero.  At March 31, 2014, the present value of the theoretical maximum payout using a 3% discount factor and current exchange rate was $45,416 thousand.  Conversely, if the contract had expired on March 31, 2014, with the FTSE index at £6,598.40, there would have been no settlement amount.

The Company's equity index put option contracts contain provisions that require collateralization of the fair value, as calculated by the counterparty, above a specified threshold, which is based on the Company's financial strength ratings (Moody's Investors Service, Inc.) and/or debt ratings (Standard & Poor's Ratings Services).  The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position on March 31, 2014, was $37,083 thousand for which the Company had posted collateral with a market value of $30,014 thousand.  If on March 31, 2014, the Company's ratings were such that the collateral threshold was zero, the Company's collateral requirement would increase by $55,000 thousand.
