As of December 2009 and November 2008, the fair value of financial instruments received as
collateral by the firm that it was permitted to deliver or repledge was $561 billion and $578 billion,respectively, of which the firm delivered or repledged $392 billion and $445 billion, respectively.
This description is remarkably similar in financial statements for both U.S. and European banks; thus data on pledgable collateral is at least to some extent comparable across these institutions.
