[1] | In the Company's Consolidated Statement of Assets, Liabilities, and Equity, all balances associated with repurchase agreements, reverse repurchase agreements, and financial derivatives are presented on a gross basis.
[2] | 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, the Company has reduced the amount of financial instruments transferred or pledged as collateral related to the Company's reverse repurchase agreements and cash collateral pledged on the Company's financial derivative liabilities. Total financial instruments transferred or pledged as collateral on the Company's reverse repurchase agreements as of June 30, 2018 and December 31, 2017 were $1.69 billion and $1.41 billion, respectively. As of June 30, 2018 and December 31, 2017, total cash collateral on financial derivative assets excludes excess net cash collateral pledged of $3.1 million and $6.4 million, respectively. As of June 30, 2018 and December 31, 2017, total cash collateral on financial derivative liabilities excludes excess cash collateral pledged of $9.8 million and $16.6 million, respectively.
[3] | 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.
[4] | See Note 2 and Note 3 in Notes to Consolidated Financial Statements.
[5] | See Note 2 and Note 3 in Notes to Consolidated Financial Statements.
[6] | In general, securities received pursuant to repurchase agreements were delivered to counterparties in short sale transactions.
[7] | In general, securities received pursuant to repurchase agreements were delivered to counterparties in short sale transactions.
