2007 compared with 2006 total net revenue of $ 71.4 billion was up $ 9.4 billion , or 15% ( 15 % ) , from the prior year . higher net interest income , very strong private equity gains , record asset management , administration and commissions revenue , higher mortgage fees and related income and record investment banking fees contributed to the revenue growth . these increases were offset partially by lower trading revenue . investment banking fees grew in 2007 to a level higher than the pre- vious record set in 2006 . record advisory and equity underwriting fees drove the results , partially offset by lower debt underwriting fees . for a further discussion of investment banking fees , which are primarily recorded in ib , see the ib segment results on pages 40 201342 of this annual report . principal transactions revenue consists of trading revenue and private equity gains . trading revenue declined significantly from the 2006 level , primarily due to markdowns in ib of $ 1.4 billion ( net of hedges ) on subprime positions , including subprime cdos , and $ 1.3 billion ( net of fees ) on leveraged lending funded loans and unfunded commitments . also in ib , markdowns in securitized products on nonsubprime mortgages and weak credit trading performance more than offset record revenue in currencies and strong revenue in both rates and equities . equities benefited from strong client activity and record trading results across all products . ib 2019s credit portfolio results increased compared with the prior year , primarily driven by higher revenue from risk management activities . the increase in private equity gains from 2006 reflected a significantly higher level of gains , the classification of certain private equity carried interest as compensation expense and a fair value adjustment in the first quarter of 2007 on nonpublic private equity investments resulting from the adoption of sfas 157 ( 201cfair value measurements 201d ) . for a further discussion of principal transactions revenue , see the ib and corporate segment results on pages 40 201342 and 59 201360 , respectively , and note 6 on page 122 of this annual report . lending & deposit-related fees rose from the 2006 level , driven pri- marily by higher deposit-related fees and the bank of new york transaction . for a further discussion of lending & deposit-related fees , which are mostly recorded in rfs , tss and cb , see the rfs segment results on pages 43 201348 , the tss segment results on pages 54 201355 , and the cb segment results on pages 52 201353 of this annual report . asset management , administration and commissions revenue reached a level higher than the previous record set in 2006 . increased assets under management and higher performance and placement fees in am drove the record results . the 18% ( 18 % ) growth in assets under management from year-end 2006 came from net asset inflows and market appreciation across all segments : institutional , retail , private bank and private client services . tss also contributed to the rise in asset management , administration and commissions revenue , driven by increased product usage by new and existing clients and market appreciation on assets under custody . finally , commissions revenue increased , due mainly to higher brokerage transaction volume ( primarily included within fixed income and equity markets revenue of ib ) , which more than offset the sale of the insurance business by rfs in the third quarter of 2006 and a charge in the first quarter of 2007 resulting from accelerated surrenders of customer annuities . for additional information on these fees and commissions , see the segment discussions for ib on pages 40 201342 , rfs on pages 43 201348 , tss on pages 54 201355 , and am on pages 56 201358 , of this annual report . the favorable variance resulting from securities gains in 2007 compared with securities losses in 2006 was primarily driven by improvements in the results of repositioning of the treasury invest- ment securities portfolio . also contributing to the positive variance was a $ 234 million gain from the sale of mastercard shares . for a fur- ther discussion of securities gains ( losses ) , which are mostly recorded in the firm 2019s treasury business , see the corporate segment discussion on pages 59 201360 of this annual report . consol idated results of operat ions .
