For certain annuity contracts that are subject to the GreyCastle Life Retro Arrangements, future policy benefit reserves were historically increased for the impact of changes in unrealized gains on investments supporting such contracts as if the gains had been realized, with a corresponding entry to other comprehensive income ("Shadow Adjustments").

▪	Global Lines - decrease of 2.6%, for the three months ended March 31, 2018, is mainly driven by lower new business in political risk & trade credit and London wholesale business lines. These decreases were partially offset by higher premiums in accident & health attributable in part to rate improvement as compared to prior year.

▪	International - increase of 17.9%, for the three months ended March 31, 2018, is attributable to higher retention in international casualty and favorable pricing in international property and international financial lines.

▪	North America - increase of 5.6%, for the three months ended March 31, 2018, due to higher renewal business in global risk management, higher retention and rate improvement in construction and growth in cybertech business lines.

This includes our estimate of equity risk embedded in the hedge fund and private investments portfolios with such estimates utilizing market exposures provided to us by certain individual fund investments, internal statistical analyses, and/or various assumptions regarding illiquidity and concentrations.

(3)	The estimated impact on the fair value of our fixed income portfolio of an immediate hypothetical +100 basis point increase in all global government related, corporate and structured security spreads to which our fixed income portfolio is exposed.

(4)	The estimated impact on the fair value of our fixed income portfolio of an immediate hypothetical +10% increase in all global government related, corporate and structured security spreads to which our fixed income portfolio is exposed.

Our investment portfolio VaR at March 31, 2018 is not necessarily indicative of future VaR levels as these are based on statistical estimates of possible price changes and, therefore, exclude other sources of investment return such as coupon and dividend income.

(6)

The VaR results are the standalone VaRs, based on the prescribed methodology, for each component of our Total Investment Portfolio. The standalone VaRs of the individual components are non-additive, with the difference between the summation of the individual component VaRs and their respective aggregations being due to diversification benefits across the individual components. In the case of the VaR results for our Total Investment Portfolio, the results also include the impact associated with our insurance and other strategic investments.

Our Total Investment Portfolio also includes our insurance and other strategic investments that do not form part of our Fixed Income Portfolio or Non-Fixed Income Portfolio. The individual results reported in the above table for our Total Investment Portfolio therefore represent the aggregate impact on our Fixed Income Portfolio, Non-Fixed Income Portfolio and the majority of our insurance and other strategic investments.
