[5] When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a specific asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.

[6] For the purpose of this presentation, for each row the total amount of financial instruments transferred or pledged and cash collateral (received) or pledged may not exceed the applicable gross amount of assets or (liabilities) as presented here. Therefore, we have reduced the amount of financial instruments transferred or pledged as collateral related to our reverse repurchase agreements and cash collateral pledged on our financial derivative liabilities. Total financial instruments transferred or pledged as collateral on our reverse repurchase agreements as of June 30, 2014 and December 31, 2013 were $1.39 billion and $1.48 billion, respectively. As of June 30, 2014 and December 31, 2013, total cash collateral on financial derivative assets excludes excess net cash collateral received of $1.1 million and pledged of $3.2 million, respectively. As of June 30, 2014 and December 31, 2013, total cash collateral on financial derivative liabilities excludes excess cash collateral pledged of $37.4 million and $36.4 million, respectively.
