Question:
what was the change in millions of total shareholders' equity from 2012 to 2013?


pre_text: management 2019s discussion and analysis balance sheet analysis and metrics as of december 2013 , total assets on our consolidated statements of financial condition were $ 911.51 billion , a decrease of $ 27.05 billion from december 2012 .
this decrease was primarily due to a decrease in financial instruments owned , at fair value of $ 67.89 billion , primarily due to decreases in u.s .
government and federal agency obligations , non-u.s .
government and agency obligations , derivatives and commodities , and a decrease in other assets of $ 17.11 billion , primarily due to the sale of a majority stake in our americas reinsurance business in april 2013 .
these decreases were partially offset by an increase in collateralized agreements of $ 48.07 billion , due to firm and client activity .
as of december 2013 , total liabilities on our consolidated statements of financial condition were $ 833.04 billion , a decrease of $ 29.80 billion from december 2012 .
this decrease was primarily due to a decrease in other liabilities and accrued expenses of $ 26.35 billion , primarily due to the sale of a majority stake in both our americas reinsurance business in april 2013 and our european insurance business in december 2013 , and a decrease in collateralized financings of $ 9.24 billion , primarily due to firm financing activities .
this decrease was partially offset by an increase in payables to customers and counterparties of $ 10.21 billion .
as of december 2013 , our total securities sold under agreements to repurchase , accounted for as collateralized financings , were $ 164.78 billion , which was 5% ( 5 % ) higher and 4% ( 4 % ) higher than the daily average amount of repurchase agreements during the quarter ended and year ended december 2013 , respectively .
the increase in our repurchase agreements relative to the daily average during 2013 was primarily due to an increase in client activity at the end of the period .
as of december 2012 , our total securities sold under agreements to repurchase , accounted for as collateralized financings , were $ 171.81 billion , which was essentially unchanged and 3% ( 3 % ) higher than the daily average amount of repurchase agreements during the quarter ended and year ended december 2012 , respectively .
the increase in our repurchase agreements relative to the daily average during 2012 was primarily due to an increase in firm financing activities at the end of the period .
the level of our repurchase agreements fluctuates between and within periods , primarily due to providing clients with access to highly liquid collateral , such as u.s .
government and federal agency , and investment-grade sovereign obligations through collateralized financing activities .
the table below presents information on our assets , unsecured long-term borrowings , shareholders 2019 equity and leverage ratios. .
post_text: leverage ratio .
