Some cooperative banks are criticized for diluting their cooperative principles. Principles 2-4 of the "Statement on the Co-operative Identity" can be interpreted to require that members must control both the governance systems and capital of their cooperatives. A cooperative bank that raises capital on public stock markets creates a second class of shareholders who compete with the members for control. In some circumstances, the members may lose control. This effectively means that the bank ceases to be a cooperative. Accepting deposits from non-members may also lead to a dilution of member control.
