capital levels. These capital ratios are reported quarterly on the Call Report or Thrift Financial Report. Although Tier 1 capital has traditionally been emphasized, in the Late-2000s recession regulators and investors began to focus on tangible common equity, which is different from Tier 1 capital in that it excludes preferred equity. Regulatory capital requirements typically (although not always) are imposed at both an individual bank entity level and at a group (or sub-group) level. This may therefore mean that several different regulatory capital regimes apply throughout a bank group at different levels, each under the supervision of a different regulator. Regulatory capital In the Basel II accord bank capital has been divided into two "tiers", each with some subdivisions. Tier 1 capital Tier 1 capital, the more important of the two, consists largely of shareholders' equity and disclosed reserves. This is the amount paid up to originally purchase the stock (or shares) of the Bank (not the amount those shares are currently trading for on the stock exchange), retained profits subtracting accumulated losses, and other qualifiable Tier 1 capital securities (see below). In simple terms, if the original stockholders contributed $100 to buy their stock and the Bank has made $20 in retained earnings each year since, paid out no dividends, had no other forms of capital and made no losses, after 10 years the Bank's tier one capital would be $300. Shareholders equity and retained earnings are now commonly referred to as "Core" Tier 1 capital, whereas Tier 1 is core Tier 1 together with other qualifying Tier 1 capital securities. In India, the Tier 1 capital is defined as "'Tier I Capital' means "owned fund" as reduced by investment in shares of other non-banking financial companies and in shares, debentures, bonds, outstanding loans and advances including hire purchase and lease finance made to and deposits with subsidiaries and companies in the same group exceeding, in aggregate, ten per cent of the owned fund; and perpetual debt instruments issued by a systemically important non-deposit taking non-banking financial company in each year to the extent it does not exceed 15% of the aggregate Tier I Capital of such company as on March 31 of the previous accounting year;" (as per Non-Banking Financial (Non-Deposit Accepting or Holding) Companies Prudential Norms (Reserve Bank) Directions, 2007) In the context of NBFCs in India, the Tier I capital is nothing but net owned funds.
