sources of liquidity primary sources of liquidity for citigroup and its principal subsidiaries include : 2022 deposits ; 2022 collateralized financing transactions ; 2022 senior and subordinated debt ; 2022 commercial paper ; 2022 trust preferred and preferred securities ; and 2022 purchased/wholesale funds .
citigroup 2019s funding sources are diversified across funding types and geography , a benefit of its global franchise .
funding for citigroup and its major operating subsidiaries includes a geographically diverse retail and corporate deposit base of $ 774.2 billion .
these deposits are diversified across products and regions , with approximately two-thirds of them outside of the u.s .
this diversification provides the company with an important , stable and low-cost source of funding .
a significant portion of these deposits has been , and is expected to be , long-term and stable , and are considered to be core .
there are qualitative as well as quantitative assessments that determine the company 2019s calculation of core deposits .
the first step in this process is a qualitative assessment of the deposits .
for example , as a result of the company 2019s qualitative analysis certain deposits with wholesale funding characteristics are excluded from consideration as core .
deposits that qualify under the company 2019s qualitative assessments are then subjected to quantitative analysis .
excluding the impact of changes in foreign exchange rates and the sale of our retail banking operations in germany during the year ending december 31 , 2008 , the company 2019s deposit base remained stable .
on a volume basis , deposit increases were noted in transaction services , u.s .
retail banking and smith barney .
this was partially offset by the company 2019s decision to reduce deposits considered wholesale funding , consistent with the company 2019s de-leveraging efforts , and declines in international consumer banking and the private bank .
citigroup and its subsidiaries have historically had a significant presence in the global capital markets .
the company 2019s capital markets funding activities have been primarily undertaken by two legal entities : ( i ) citigroup inc. , which issues long-term debt , medium-term notes , trust preferred securities , and preferred and common stock ; and ( ii ) citigroup funding inc .
( cfi ) , a first-tier subsidiary of citigroup , which issues commercial paper , medium-term notes and structured equity-linked and credit-linked notes , all of which are guaranteed by citigroup .
other significant elements of long- term debt on the consolidated balance sheet include collateralized advances from the federal home loan bank system , long-term debt related to the consolidation of icg 2019s structured investment vehicles , asset-backed outstandings , and certain borrowings of foreign subsidiaries .
each of citigroup 2019s major operating subsidiaries finances its operations on a basis consistent with its capitalization , regulatory structure and the environment in which it operates .
particular attention is paid to those businesses that for tax , sovereign risk , or regulatory reasons cannot be freely and readily funded in the international markets .
citigroup 2019s borrowings have historically been diversified by geography , investor , instrument and currency .
decisions regarding the ultimate currency and interest rate profile of liquidity generated through these borrowings can be separated from the actual issuance through the use of derivative instruments .
citigroup is a provider of liquidity facilities to the commercial paper programs of the two primary credit card securitization trusts with which it transacts .
citigroup may also provide other types of support to the trusts .
as a result of the recent economic downturn , its impact on the cashflows of the trusts , and in response to credit rating agency reviews of the trusts , the company increased the credit enhancement in the omni trust , and plans to provide additional enhancement to the master trust ( see note 23 to consolidated financial statements on page 175 for a further discussion ) .
this support preserves investor sponsorship of our card securitization franchise , an important source of liquidity .
banking subsidiaries there are various legal limitations on the ability of citigroup 2019s subsidiary depository institutions to extend credit , pay dividends or otherwise supply funds to citigroup and its non-bank subsidiaries .
the approval of the office of the comptroller of the currency , in the case of national banks , or the office of thrift supervision , in the case of federal savings banks , is required if total dividends declared in any calendar year exceed amounts specified by the applicable agency 2019s regulations .
state-chartered depository institutions are subject to dividend limitations imposed by applicable state law .
in determining the declaration of dividends , each depository institution must also consider its effect on applicable risk-based capital and leverage ratio requirements , as well as policy statements of the federal regulatory agencies that indicate that banking organizations should generally pay dividends out of current operating earnings .
non-banking subsidiaries citigroup also receives dividends from its non-bank subsidiaries .
these non-bank subsidiaries are generally not subject to regulatory restrictions on dividends .
however , as discussed in 201ccapital resources and liquidity 201d on page 94 , the ability of cgmhi to declare dividends can be restricted by capital considerations of its broker-dealer subsidiaries .
cgmhi 2019s consolidated balance sheet is liquid , with the vast majority of its assets consisting of marketable securities and collateralized short-term financing agreements arising from securities transactions .
cgmhi monitors and evaluates the adequacy of its capital and borrowing base on a daily basis to maintain liquidity and to ensure that its capital base supports the regulatory capital requirements of its subsidiaries .
some of citigroup 2019s non-bank subsidiaries , including cgmhi , have credit facilities with citigroup 2019s subsidiary depository institutions , including citibank , n.a .
borrowings under these facilities must be secured in accordance with section 23a of the federal reserve act .
there are various legal restrictions on the extent to which a bank holding company and certain of its non-bank subsidiaries can borrow or obtain credit from citigroup 2019s subsidiary depository institutions or engage in certain other transactions with them .
in general , these restrictions require that transactions be on arm 2019s length terms and be secured by designated amounts of specified collateral .
