while we have historically generated the substantial majority of our revenues from companies in the life science industry , we have also grown our base of technology customers and intend to continue to focus on increasing the revenues from customers in the technology industry . our most significant customers in any given period generally vary from period to period due to the timing of implementation and related revenue recognition over those periods of larger projects . during the fiscal year ended september 30 , 2013 , two customers , merck & co. , inc. and johnson & johnson health services , inc. , accounted for approximately 12 % each of our total revenues . during the fiscal year ended september 30 , 2012 , two customers accounted for approximately 14 % and 10 % of our total revenues , respectively . during the fiscal year ended september 30 , 2011 , two customers accounted for 15 % and 12 % of our total revenues , respectively . for the fiscal year ended september 30 , 2013 , approximately 14 % of our revenues were derived from customers located outside the united states . for the fiscal years ended september 30 , 2011 , 2012 and 2013 , our revenues were $ 65.2 million , $ 84.3 million and $ 101.9 million , respectively , representing year-over-year growth of approximately 21 % from 2012 to 2013 and year-over-year growth of approximately 29 % from 2011 to 2012. as announced in september 2013 , we recently experienced challenges in sales execution and do not anticipate maintaining this growth rate throughout our 2014 fiscal year . on september 30 , 2013 , the company commenced a plan to align its workforce with the company 's strategic initiatives . the company recorded a workforce reduction restructuring charge of $ 1.2 million in connection with the alignment . 42 key business metrics in addition to the measures of financial performance presented in our consolidated financial statements , we use certain key metrics to evaluate and manage our business , including four-quarter revenues from current customers and adjusted ebitda . we use these key metrics internally to manage the business , and we believe they are useful for investors to compare key financial data from various periods . four-quarter revenues from existing customers we derive a large majority of revenues from existing customers , which we define as customers from which we have generated revenues in each of the preceding four quarters , which would exclude historical customers of leapfrogrx . we measure four-quarter revenues from our existing license and subscription customers by calculating the sum of revenues recognized during the last four quarters from any customer that has contributed revenue in each of the preceding four quarters . we believe four-quarter revenues from existing customers provide us and investors with a metric to measure the historical revenue visibility in our business . we also use this metric internally to understand the proportion of revenues being generated in any period from existing customers as compared to entirely new customers or customers with whom we have not been recently engaged . this measure helps us guide our sales activities and establish budgets and operational goals for our sales function . our four-quarter revenues from existing customers for the periods presented were as follows : replace_table_token_6_th non-gaap financial measure adjusted ebitda adjusted ebitda is a financial measure that is not calculated in accordance with generally accepted accounting principles in the united states ( u.s. gaap ) . we define adjusted ebitda as net loss before leapfrogrx compensation charges , as discussed below , stock-based compensation , depreciation and amortization , interest expense , net , other income ( expenses ) , net , and provision for income taxes . we believe adjusted ebitda provides investors with consistency and comparability with our past financial performance and facilitates period-to-period comparisons of our operating results and our competitors ' operating results . we also use this measure internally to establish budgets and operational goals to manage our business and evaluate our performance . we understand that , although adjusted ebitda is frequently used by investors and securities analysts in their evaluations of companies , adjusted ebitda has limitations as an analytical tool , and it should not be considered in isolation or as a substitute for analysis of our results of operations as reported under u.s. gaap . these limitations include : adjusted ebitda does not include the effect of the leapfrogrx compensation charges , which are a cash expense ; adjusted ebitda does not reflect stock-based compensation expense ; depreciation and amortization are non-cash charges , and the assets being depreciated or amortized will often have to be replaced in the future ; adjusted ebitda does not reflect any cash requirements for these replacements ; 43 adjusted ebitda does not reflect restructuring expense ; adjusted ebitda does not reflect cash requirements for income taxes and the cash impact of other income or expense ; and other companies in our industry may calculate adjusted ebitda differently than we do , limiting its usefulness as a comparative measure . replace_table_token_7_th adjusted ebitda was $ 9.6 million , $ 5.0 million and $ 4.4 million for the fiscal years ended september 30 , 2013 , 2012 and 2011 , respectively . our adjusted ebitda for the fiscal years ended september 30 , 2013 and 2012 increased primarily due to increases in total revenues , which were partially offset by increased expenses . the increase in expenses was primarily due to increases in personnel costs arising principally from headcount and salary increases and increased use of third-party contractors . key components of results of operations revenues revenues are comprised of license and implementation revenues and saas and maintenance revenues . story_separator_special_tag sales and marketing sales and marketing expenses increased by $ 5.7 million , or 41 % , to $ 19.6 million during the fiscal year ended september 30 , 2012 as compared to $ 13.9 million for the fiscal year ended september 30 , 2011. the increase was primarily the result of an increase of $ 5.1 million in personnel costs due primarily to increased headcount , including personnel from leapfrogrx , an increase of $ 0.3 million in expenses related to direct marketing events and an increase of $ 0.3 million in travel-related expenses . the increase in personnel costs includes $ 1.1 million of leapfrogrx compensation charges and an increase of $ 1.0 million in stock-based compensation expense . general and administrative general and administrative expenses increased $ 2.7 million , or 35 % , to $ 10.6 million during the fiscal year ended september 30 , 2012 as compared to $ 7.9 million for the fiscal year ended september 30 , 2011. this increase was primarily due to an increase in personnel costs due to increased headcount , including personnel from leapfrogrx . the increase in personnel costs includes $ 0.7 million of leapfrogrx compensation charges . 52 interest and other expense , net replace_table_token_19_th interest expense , net primarily relates to financing costs related to our term loan and capital leases . other expense , net increased primarily due to an increase of $ 0.3 million in changes in the fair value of a convertible preferred stock warrant during the fiscal year ended september 30 , 2012 as compared to the fiscal year ended september 30 , 2011. provision for income taxes replace_table_token_20_th provision for income taxes increased $ 0.1 million to $ 0.3 million for the fiscal year ended september 30 , 2012 as compared to $ 0.2 million for the fiscal year ended september 30 , 2011. this change was primarily the result of an increase in the income tax provision in foreign jurisdictions due to an increase in income from our foreign operations . for the fiscal year ended september 30 , 2012 , the tax expense computed using the statutory federal tax rate would have been a benefit of $ 1.8 million as compared to the income tax provision of $ 0.3 million . the difference was primarily due to the valuation allowance , partially offset by research and development tax credits and state taxes net of federal benefit . for the fiscal year ended september 30 , 2011 , the tax expense computed using the statutory federal tax rate would have been an expense of $ 0.6 million as compared to the income tax provision of $ 0.2 million . the difference was primarily due to the valuation allowance and research and development tax credits , partially offset by permanent differences for expenses not deductible for tax purposes and a change in the state effective rate . quarterly results of operations ( unaudited ) the following table sets forth our unaudited quarterly statements of operations data for the last eight fiscal quarters . the information for each of these quarters has been prepared on the same basis as the audited annual financial statements included elsewhere in this annual report and , in the opinion of management , includes all adjustments , which includes only normal recurring adjustments , necessary for the fair presentation of the results of operations for these periods . this data should be read in conjunction with our audited consolidated financial 53 statements and related notes included elsewhere in this annual report . these quarterly operating results are not necessarily indicative of our operating results for any future period . replace_table_token_21_th 54 replace_table_token_22_th liquidity and capital resources as of september 30 , 2013 , we had cash and cash equivalents of $ 103.4 million . since inception , we have financed our operations primarily through proceeds from the issuance of capital stock and since 2006 through cash flows from operations . we expended cash flows in operating activities in the fiscal year ended september 30 , 2013 of $ 0.4 million and generated cash flows from operating activities in the fiscal years ended september 30 , 2012 and 2011 of $ 5.7 million and $ 3.1 million , respectively . we believe our current cash and cash equivalents are sufficient to meet our cash needs for at least the next twelve months . our future capital requirements will depend on many factors , including our rate of revenue growth , the expansion of our sales and marketing activities , and the timing and extent of spending to support research and development efforts and expansion of our business and capital expenditures for the purchase of computer hardware and software . to the extent that existing cash and cash equivalents and cash from operations are insufficient to fund our future activities , we may elect to raise additional capital through the sale of additional equity or debt securities , obtain a credit facility or sell certain assets . if additional funds are raised through the issuance of debt securities , these securities could have rights , preferences and privileges senior to holders of common stock , and terms of any debt could impose restrictions on our operations . the sale of additional equity or convertible debt securities could result in additional dilution to our stockholders and additional financing may not be available in amounts or on terms acceptable to us . we may also seek to invest in or acquire complementary businesses or technologies , any of which could also require us to seek additional equity or debt financing . additional funds may not be available on terms favorable to us or at all . 55 story_separator_special_tag margin-bottom:0pt ;
