capital resources and liquidity capital resources overview capital is generally generated via earnings from operating businesses. this is augmented through issuance of common stock, convertible preferred stock, preferred stock, subordinated debt, and equity issued through awards under employee benefit plans. capital is used primarily to support assets in the company 2019s businesses and to absorb unexpected market, credit or operational losses. the company 2019s uses of capital, particularly to pay dividends and repurchase common stock, became severely restricted during the latter half of 2008. see 201cthe company, 201d 201cmanagement 2019s discussion and analysis 2013 events in 2008, 201d 201ctarp and other regulatory programs, 201d 201crisk factors 201d and 201ccommon equity 201d on pages 2, 9, 44, 47 and 95, respectively. citigroup 2019s capital management framework is designed to ensure that citigroup and its principal subsidiaries maintain sufficient capital consistent with the company 2019s risk profile, all applicable regulatory standards and guidelines, and external rating agency considerations. the capital management process is centrally overseen by senior management and is reviewed at the consolidated, legal entity, and country level. senior management oversees the capital management process of citigroup and its principal subsidiaries mainly through citigroup 2019s finance and asset and liability committee (finalco). the committee is composed of the senior-most management of citigroup for the purpose of engaging management in decision-making and related discussions on capital and liquidity items. among other things, the committee 2019s responsibilities include: determining the financial structure of citigroup and its principal subsidiaries; ensuring that citigroup and its regulated entities are adequately capitalized; determining appropriate asset levels and return hurdles for citigroup and individual businesses; reviewing the funding and capital markets plan for citigroup; and monitoring interest-rate risk, corporate and bank liquidity, the impact of currency translation on non-u.s. earnings and capital. the finalco has established capital targets for citigroup and for significant subsidiaries. at december 31, 2008, these targets exceeded the regulatory standards. common and preferred stock issuances as discussed under 201cevents in 2008 201d on page 9, during 2008, the company issued $45 billion in preferred stock and warrants under tarp, $12.5 billion of convertible preferred stock in a private offering, $11.7 billion of non-convertible preferred stock in public offerings, $3.2 billion of convertible preferred stock in public offerings, and $4.9 billion of common stock in public offerings. on january 23, 2009, pursuant to our prior agreement with the purchasers of the $12.5 billion convertible preferred stock issued in the private offering, the conversion price was reset from $31.62 per share to $26.35 per share. the reset will result in citigroup 2019s issuing approximately 79 million additional common shares if converted. there will be no impact to net income, total stockholders 2019 equity or capital ratios due to the reset. however, the reset will result in a reclassification from retained earnings to additional paid-in capital of $1.2 billion to reflect the benefit of the reset to the preferred stockholders. capital ratios citigroup is subject to risk-based capital ratio guidelines issued by the federal reserve board (frb). capital adequacy is measured via two risk- based ratios, tier 1 and total capital (tier 1 + tier 2 capital). tier 1 capital is considered core capital while total capital also includes other items such as subordinated debt and loan loss reserves. both measures of capital are stated as a percentage of risk-weighted assets. risk-weighted assets are measured primarily on their perceived credit risk and include certain off-balance-sheet exposures, such as unfunded loan commitments and letters of credit, and the notional amounts of derivative and foreign- exchange contracts. citigroup is also subject to the leverage ratio requirement, a non-risk-based asset ratio, which is defined as tier 1 capital as a percentage of adjusted average assets. to be 201cwell capitalized 201d under federal bank regulatory agency definitions, a bank holding company must have a tier 1 capital ratio of at least 6% (6%), a total capital ratio of at least 10% (10%), and a leverage ratio of at least 3% (3%), and not be subject to an frb directive to maintain higher capital levels. as noted in the following table, citigroup maintained a 201cwell capitalized 201d position during both 2008 and 2007. citigroup regulatory capital ratios at year end 2008 2007.
