The sensitivity factors utilized for 2016 and presented above were selected based on historical data from 1996 to 2016, as follows (see the table below): ?
a 100 basis point parallel shift in the yield curve is consistent with a one standard deviation movement of the benchmark ten-year treasury yield; ?
a 20 percent drop for equity and alternative investments is broadly consistent with a one standard deviation movement in the S&P 500; and ?
a 10 percent depreciation of foreign currency exchange rates is consistent with a one standard deviation movement in the U. S.  dollar (USD)/Japanese yen (JPY) exchange rate.

Risk Monitoring and Limits The risk monitoring responsibilities, owned by the business units, include ensuring compliance with market risk limits and escalation and remediation of limit breaches.
Such activities must be reported to the ERM Market Risk team by the relevant business unit.
This monitoring approach is aligned with our overall risk limits framework.
To control our exposure to market risk, we rely on a three-tiered hierarchy of limits that the CMRO closely monitors and reports to our CRO, senior management and risk committees.
See Risk Appetite, Limits, Identification, and Measurement – Risk Limits herein for further information on our three-tiered hierarchy of limits.
LIQUIDITY RISK MANAGEMENT Liquidity risk is defined as the risk that our financial condition will be adversely affected by the inability or perceived inability to meet our short-term cash, collateral or other financial obligations.
Failure to appropriately manage liquidity risk can result in insolvency, reduced operating flexibility, increased costs, reputational harm and regulatory action.
AIG and its legal entities seek to maintain sufficient liquidity during both the normal course of business and under defined liquidity stress scenarios to ensure that sufficient cash will be available to meet the obligations as they come due.
AIG Parent liquidity risk tolerance levels are designed to allow it to meet our financial obligations for a minimum of six- months under a liquidity stress scenario.
We maintain liquidity limits and minimum coverage ratios designed to ensure that funding needs are met under varying market conditions.
If we project that we will breach these tolerances, we will assess and determine appropriate liquidity management actions.
However, the market conditions in effect at that time may not permit us to achieve an increase in liquidity sources or a reduction in liquidity requirements.
Risk Identification The following sources of liquidity and funding risks could impact our ability to meet short-term financial obligations as they come due.  ?
Market/Monetization Risk: Assets may not be readily transformed into cash due to unfavorable market conditions.
Market liquidity risk may limit our ability to sell assets at reasonable values to meet liquidity needs.  ?
Cash Flow Mismatch Risk: Discrete and cumulative cash flow mismatches or gaps over short-term horizons under both expected and adverse business conditions may create future liquidity shortfalls.  ?
Event Funding Risk: Additional funding may be required as the result of a trigger event.
Event funding risk comes in many forms and may result from a downgrade in credit ratings, a market event, or some other event that creates a funding obligation or limits existing funding options.  ?
Financing Risk: We may be unable to raise additional cash on a secured or unsecured basis due to unfavorable market conditions, AIG-specific issues, or any other issue that impedes access to additional funding.

Adjustments for accident year loss ratio, as adjusted, and accident year combined ratio, as adjusted:
## Table 2 ##
(a) Consistent with our definition of Pre-tax operating income, excludes loss reserve discount.
Business and Financial Highlights The net premiums written decrease in 2016 was driven by the Swiss Re quota share treaty, portfolio optimization and execution on our pricing strategy, partially offset by growth in targeted lines of business.
The increase in net losses was driven by net adverse prior year reserve development.
The acquisition expense decrease was primarily related to the 2016 Swiss Re quota share treaty.
The general operating expense decrease was driven by lower employee-related expenses and other expense savings initiatives.
Lower net investment income was driven primarily by lower alternative investment returns due to weaker performance in equity markets compared to prior years.
We continue to reduce the relative size of our U. S.  casualty portfolio within Liability and Financial Lines and consequently expect that net premiums written will continue to decline through 2017, in large part driven by the impact of our continued strategy on risk selection, disciplined underwriting and execution of our reinsurance strategy to further reduce risk.
As discussed in the Executive Summary, in January 2017, we entered into an adverse development reinsurance agreement with NICO, which covers 80 percent of up to $9 billion of potential future prior year development on substantially all of our U. S.  Casualty and Financial Lines exposures for accident years 2015 and prior.
Under U. S.  GAAP, any potential future prior year development would be recognized immediately as losses are incurred; however, the related recoveries under the reinsurance agreement would be deferred and recognized over the expected recovery period.
