management 2019s discussion and analysis liquidity risk management liquidity is of critical importance to financial institutions .
most of the recent failures of financial institutions have occurred in large part due to insufficient liquidity .
accordingly , the firm has in place a comprehensive and conservative set of liquidity and funding policies to address both firm-specific and broader industry or market liquidity events .
our principal objective is to be able to fund the firm and to enable our core businesses to continue to serve clients and generate revenues , even under adverse circumstances .
we manage liquidity risk according to the following principles : excess liquidity .
we maintain substantial excess liquidity to meet a broad range of potential cash outflows and collateral needs in a stressed environment .
asset-liability management .
we assess anticipated holding periods for our assets and their expected liquidity in a stressed environment .
we manage the maturities and diversity of our funding across markets , products and counterparties , and seek to maintain liabilities of appropriate tenor relative to our asset base .
contingency funding plan .
we maintain a contingency funding plan to provide a framework for analyzing and responding to a liquidity crisis situation or periods of market stress .
this framework sets forth the plan of action to fund normal business activity in emergency and stress situations .
these principles are discussed in more detail below .
excess liquidity our most important liquidity policy is to pre-fund our estimated potential cash and collateral needs during a liquidity crisis and hold this excess liquidity in the form of unencumbered , highly liquid securities and cash .
we believe that the securities held in our global core excess would be readily convertible to cash in a matter of days , through liquidation , by entering into repurchase agreements or from maturities of reverse repurchase agreements , and that this cash would allow us to meet immediate obligations without needing to sell other assets or depend on additional funding from credit-sensitive markets .
as of december 2012 and december 2011 , the fair value of the securities and certain overnight cash deposits included in our gce totaled $ 174.62 billion and $ 171.58 billion , respectively .
based on the results of our internal liquidity risk model , discussed below , as well as our consideration of other factors including , but not limited to , a qualitative assessment of the condition of the financial markets and the firm , we believe our liquidity position as of december 2012 was appropriate .
the table below presents the fair value of the securities and certain overnight cash deposits that are included in our gce .

government and federal agency obligations ( including highly liquid u.s .
federal agency mortgage-backed obligations ) , all of which are eligible as collateral in federal reserve open market operations and ( ii ) certain overnight u.s .
dollar cash deposits .
the non-u.s .
dollar-denominated excess is composed of only unencumbered german , french , japanese and united kingdom government obligations and certain overnight cash deposits in highly liquid currencies .
we strictly limit our excess liquidity to this narrowly defined list of securities and cash because they are highly liquid , even in a difficult funding environment .
we do not include other potential sources of excess liquidity , such as less liquid unencumbered securities or committed credit facilities , in our gce .
