this collateral comes primarily from citi 2019s trading assets and its secured lending , and is part of citi 2019s client matched-book activity given that citi both borrows and lends similar asset types on a secured basis .
the minority of secured financing is collateralized by less liquid collateral , and supports both citi 2019s trading assets as well as the business of secured lending to customers , which is also part of citi 2019s client matched-book activity .
the less liquid secured borrowing is carefully calibrated by asset quality , tenor and counterparty exposure , including those that might be sensitive to ratings stresses , in order to increase the reliability of the funding .
citi believes there are several potential mitigants available to it in the event of stress on the secured financing markets for less liquid collateral .
citi 2019s significant liquidity resources in its non-bank entities as of december 31 , 2010 , supplemented by collateralized liquidity transfers between entities , provide a cushion .
within the matched-book activity , the secured lending positions , which are carefully managed in terms of collateral and tenor , could be unwound to provide additional liquidity under stress .
citi also has excess funding capacity for less liquid collateral with existing counterparties that can be accessed during potential dislocation .
in addition , citi has the ability to adjust the size of select trading books to provide further mitigation .
