securities from one counterparty and lending the same securities to another counterparty . we generally earn a net interest spread equal to the excess of interest earned on securities borrowing deposits over the interest paid on securities lending deposits . daily average revenue trades ( darts )  total trades divided by the number of trading days in the period . this metric is also known as average client trades per day . ebitda and ebitda excluding investment gains/losses  ebitda ( earnings before interest , taxes , depreciation and amortization ) and ebitda excluding investment gains/losses are non-gaap financial measures . we consider ebitda and ebitda excluding investment gains/losses to be important measures of our financial performance and of our ability to generate cash

covenant purposes under our holding company 's senior revolving credit facility . ebitda eliminates the non-cash effect of tangible asset depreciation and amortization and intangible asset amortization . ebitda excluding investment gains/losses also eliminates the effect of non-brokerage investment-related gains and losses that are not likely to be indicative of the ongoing operations

activities . eps excluding investment gains/losses  earnings per share ( eps ) excluding investment gains/losses is a non-gaap financial measure . we define eps excluding investment gains/losses as earnings ( loss ) per share , adjusted to remove the after-tax effect of non-brokerage investment-related gains and losses . we consider eps excluding investment gains/losses an important measure of our financial performance . gains/losses on non-brokerage investments and investment-related derivatives are excluded because we believe they are not likely to be indicative of the ongoing operations

operations is a non-gaap financial measure . we define eps from ongoing operations as earnings ( loss ) per share , adjusted to remove any significant unusual gains or charges . we consider eps from ongoing operations an important measure of the financial performance of our ongoing business . unusual gains and charges are excluded because we believe they are not likely to be indicative of the ongoing operations of our business . eps from ongoing operations should be considered in addition to , rather than as a substitute for , gaap earnings per share . fee-based investment balances  client

the company provides marketing , recordkeeping and support services for the depository institutions with respect to the money market deposit accounts . story_separator_special_tag in many matters , such as those in which substantial or indeterminate damages or fines are sought , or where cases or proceedings are in the early stages , it is not possible to determine whether a loss will be incurred , or to estimate the range of that loss , until the matter is close to resolution , in which case no accrual is made until that time . because matters may be resolved over long periods of time , accruals are adjusted as more information becomes available or when an event occurs requiring a change . significant judgment is required in making these estimates , and the actual cost of resolving a matter may ultimately differ materially from the amount accrued . valuation of guarantees we enter into guarantees in the ordinary course of business , primarily to meet the needs of our clients and to manage our asset-based revenues . we record a liability for the estimated fair value of the guarantee at its inception . if actual results differ significantly from these estimates , our results of operations could be materially affected . for further details regarding our guarantees , see the following sections under item 8 , financial statements and supplementary data  notes to consolidated financial statements : guarantees under note 14  commitments and contingencies and insured deposit account agreement under note 18  related party transactions . results of operations conditions in the u.s. equity markets significantly impact the volume of our clients ' trading activity . there is a direct correlation between the volume of our clients ' trading activity and our results of operations . we can not predict future trading volumes in the u.s. equity markets . if client trading activity increases , we expect that it would have a positive impact on our results of operations . if client trading activity declines , we expect that it would have a negative impact on our results of operations . changes in average balances , especially client margin , credit , insured deposit account and mutual fund balances , may significantly impact our results of operations . changes in interest rates also significantly impact our results of operations . we seek to mitigate interest rate risk by aligning the average duration of our interest-earning assets with that of our interest-bearing liabilities . we can not predict the direction of interest rates or the levels of client balances . if interest rates rise , we generally expect to earn a larger net interest spread . conversely , a falling interest rate environment generally would result in our earning a smaller net interest spread . financial performance metrics pre-tax income , net income , earnings per share and ebitda are key metrics we use in evaluating our financial performance . ebitda is a non-gaap financial measure . we consider ebitda to be an important measure of our financial performance and of our ability to generate cash flows to service debt , fund capital expenditures and fund other corporate investing and financing activities . ebitda is used as the denominator in the consolidated leverage ratio calculation for covenant purposes under our holding company 's senior

periods indicated , and provides reconciliations to net income , which is the most directly comparable gaap measure ( dollars in thousands ) : replace_table_token_5_th our ebitda increased for fiscal 2011 compared to fiscal 2010 , primarily due to an 8 % increase in net revenues , partially offset by a 7 % increase in total operating expenses . the increase in net revenues was due primarily to growth in average spread-based and other fee-based investment balances and an 8 % increase in total client trades , partially offset by lower net interest margin earned on the spread-based balances and lower average commissions and transaction fees per trade . the increase in total operating expenses was due primarily to increases in employee compensation and benefits and professional services expenses during fiscal 2011 and the effect of a $ 12.7 million gain on money market funds and client guarantees during fiscal 2010. detailed analysis of net revenues and operating expenses is presented later in this discussion . operating metrics our largest sources of revenues are asset-based revenues and transaction-based revenues . for fiscal 2011 , asset-based revenues and transaction-based revenues accounted for 51 % and 44 % of our net revenues , respectively . asset-based revenues consist of ( 1 ) net interest revenue , ( 2 ) insured deposit account fees and ( 3 ) investment product fees . the primary factors driving our asset-based revenues are average balances and average rates . average balances consist primarily of average client margin balances , average segregated cash balances , average client credit balances , average client insured deposit account balances , average fee-based investment balances and average securities borrowing and lending balances . average rates consist of the average interest rates and fees earned and paid on such balances . the primary factors driving our transaction-based revenues are total client trades and average commissions and transaction fees per trade . we also consider client account and client asset metrics , although we believe they are generally of less significance to our results of operations for any particular period than our metrics for asset-based and transaction-based revenues . asset-based revenue metrics we calculate the return on our interest-earning assets ( excluding conduit-based assets ) and our insured deposit account balances using a measure we refer to as net interest margin . net interest margin is calculated for a given period by dividing the annualized sum
