results of operations the following discussion is intended to provide the reader with information that will be helpful in understanding our financial statements including the changes in certain key items in comparing financial statements period to period . we also intend to provide the primary factors that accounted for those changes , as well as a summary of how certain accounting principles affect our financial statements . in addition , we are providing information about the financial results of our two operating segments to further assist in understanding how these segments and their results affect our consolidated results of operations . this discussion should be read in conjunction with our financial statements as of december 31 , 2011 and the year then ended and the notes accompanying those financial statements contained herein under item 8. as disclosed in note 2 of the notes to the consolidated financial statements , contract environmental services , inc. ( ces ' ) was acquired may 1 , 2009. the ces results of operations , for the period may 1 , 2009 to december 31 , 2009 are included in our 2009 consolidated results of operations and financial information presented below . such impact , when material and quantifiable , is discussed where we believe it would contribute to the reader 's understanding of our financial statements . during 2011 , we acquired a small regional provider of housekeeping and laundry services , which are included in our 2011 consolidated results of operations and financial information , for the period september 1 , 2011 to december 31 , 2011 , presented below . the impact of this acquisition did not have a material impact on the overall operations of company 's financial results from a consolidated or segment perspective . overview we provide management , administrative and operating expertise and services to the housekeeping , laundry , linen , facility maintenance and dietary service departments of the health care industry , including nursing homes , retirement complexes , rehabilitation centers and hospitals located throughout the united states . we believe that we are the largest provider of housekeeping and laundry management services to the long-term care industry in the united states , rendering such services to approximately 2,900 facilities in 47 states as of december 31 , 2011. although we do not directly participate in any government reimbursement programs , our clients ' reimbursements are subject to government regulation . therefore , they are directly affected by any legislation relating to medicare and medicaid reimbursement programs . 18 we provide our services primarily pursuant to full service agreements with our clients . in such agreements , we are responsible for the day to day management of the department managers and hourly employees located at our clients ' facilities . we also provide services on the basis of a management-only agreement for a very limited number of clients . our agreements with clients typically provide for renewable one year service terms , cancelable by either party upon 30 to 90 days ' notice after the initial 90-day period . we are organized into two reportable segments ; housekeeping , laundry , linen and other services ( housekeeping ) , and dietary department services ( dietary ) . at december 31 , 2011 , housekeeping is being provided at essentially all of our approximately 2,900 client facilities , generating approximating 74 % or $ 654,886,000 of 2011 total revenues . dietary is being provided to approximately 600 client facilities at december 31 , 2011 and contributed approximately 26 % or $ 234,247,000 of 2011 total revenues . housekeeping consists of managing the client 's housekeeping department which is principally responsible for the cleaning , disinfecting and sanitizing of patient rooms and common areas of a client 's facility , as well as laundering and processing of the personal clothing belonging to the facility 's patients . also within the scope of this segment 's service is the responsibility for laundering and processing of the bed linens , uniforms and other assorted linen items utilized by a client facility . dietary consists of managing the client 's dietary department which is principally responsible for food purchasing , meal preparation and providing dietician consulting professional services , which includes the development of a menu that meets the patient 's dietary needs . our ability to acquire new clients and increase revenues is affected by many factors . competitive factors consist primarily of competing with the potential client utilizing an in-house support staff to provide services similar to ours , as well as local companies which provide services similar to ours . we are unaware of any other companies , on a national or local level , which have a significant presence or impact on our procurement of new clients in our market . we believe the primary revenue drivers of our business are our ability to obtain new clients and to pass through , by means of service billing increases , increases in our cost of providing the services . in addition to the recoupment of costs increases , we endeavor to obtain modest annual revenue increases from our existing clients to preserve current profit margins at the facility level . the primary economic factor in acquiring new clients is our ability to demonstrate the cost-effectiveness of our services . this is because many of our clients ' revenues are generally highly reliant on medicare and medicaid reimbursement funding rates and mechanisms . therefore , their economic decision-making process in engaging us is driven significantly by their reimbursement funding rate structure in relation to how their costs are currently being reimbursed and the financial impact on their reimbursement as a result of engaging us for the respective services . another factor is our ability to demonstrate to potential clients the benefit of being relieved of the administrative and operational challenges related to the day-to-day management of their respective department services for which they contract with us . story_separator_special_tag consolidated investment and interest income investment and interest income , as a percentage of consolidated revenues , decreased to 0.1 % for the year ended december 31 , 2011 compared to 0.3 % for the comparable period in 2010. the decrease in investment and interest income was primarily attributable to the decrease in interest earned , and realized and unrealized net gains on our marketable securities portfolio during this period . additionally , we recognized a decrease in the market value of the investments held in our deferred compensation fund compared to an increase in the market value in the prior year . the decrease in interest income derived from our marketable securities resulted partially from a reduction in the amount of change in our marketable securities portfolio during 2011. from time to time in 2011 , we sold securities to increase cash and cash equivalents to fund our growth . additionally , we realized lower rates of return on our marketable securities and on cash and cash equivalents during the year . 24 income before income taxes consolidated as a result of the discussion above related to revenues and expenses , consolidated income before income taxes for 2011 decreased to 6.5 % , as a percentage of consolidated revenues , compared to 7.0 % in 2010. reportable segments housekeeping 's 13.0 % increase in income before income taxes is primarily attributable to the gross profit earned on the 9.9 % increase in organic reportable segment revenues along with the factors discussed above in housekeeping 's cost of services key indicators . dietary 's income before income taxes increase of 54.0 % on a reportable segment basis is primarily attributable to the 31.6 % increase in dietary revenues from 2010 along with the factors discussed above within dietary 's cost of services key indicators . consolidated income taxes our effective tax rate was 34.0 % for the year ended december 31 , 2011 and 36.4 % for 2010. the decrease in the effective tax rate was primarily the result of increased tax credits realized in 2011. the company realized tax credits from , in addition to other tax credits available , the new hire retention credit ( the nhr credit ) . the nhr credit is a one-time general business credit at the federal level that was authorized by the hiring incentives to restore employment act ( hire act ) of 2010. the nhr credit allows an employer a credit of up to $ 1,000 for each eligible worker that was retained for at least 52 consecutive weeks of qualified employment . this program ended december 31 , 2010 but the impact of the nhr credit is accordingly reflected in our income tax provision for 2011. additionally , there was a slight decrease in the effective tax rate resulting from changes in the apportionment of our income among the states within which we do business that have positively impacted our combined state income taxes . absent any significant change in federal , or state and local tax laws , we expect our effective tax rate for 2012 to approximate a rate between our 2010 rate of 36.4 % and our 2009 rate of 38.5 % . our actual 2012 rate will be impacted by the expiration of the tax credits related to the hire act and the uncertainty surrounding the renewal of the work opportunity tax credit ( wotc ) program . due to the expiration of current tax credits and the uncertainty regarding the availability of tax credits under new or potentially extended programs , the effect on our 2012 effective tax rate can not be reasonably estimated at this time . our effective tax rate differs from the federal income tax statutory rate principally because of the effect of state and local income taxes . consolidated net income as a result of the matters discussed above , consolidated net income as a percentage of revenue for 2011 decreased to 4.3 % compared to 4.5 % for 2010 . 2010 compared with 2009 the following table sets forth 2010 income statement key components that we use to evaluate our financial performance on a consolidated and reportable segment basis , as well as the percentage increases of each compared 25 to 2009 amounts . the differences between the reportable segments ' operating results and other disclosed data and our consolidated financial statements relate primarily to corporate level transactions and recording of transactions at the reportable segment level which use methods other than generally accepted accounting principles . replace_table_token_10_th revenues consolidated consolidated revenues increased 11.7 % to $ 773,956,000 in 2010 compared to $ 692,695,000 in 2009 as a result of the factors discussed below under reportable segments . our major client in 2010 and 2009 accounted for 11 % and 12 % , respectively , of consolidated revenues . at both december 31 , 2010 and 2009 amounts due from such client represented less than 1 % of our accounts receivable balance . although we expect to continue the relationship with this client , there can be no assurance thereof , and the loss of such client , or a significant reduction in the revenues we receive from this client , would have a material adverse effect on the results of operations of our two operating segments . in addition , if such client changes its payment terms it would increase our accounts receivable balance and have a material adverse effect on our cash flows and cash and cash equivalents . reportable segments housekeeping 's 11.9 % net growth in reportable segment revenues resulted primarily from an increase in revenues attributable to service agreements entered into with new clients . excluding revenue from ces operations , housekeeping segment revenue would have increased 11.0 % . dietary 's 11.4 % net growth in reportable segment revenues is primarily a result of providing this service to an increasing number of existing housekeeping clients . excluding revenue from ces operations , dietary segment

liquidity and capital resources at december 31 , 2011 , we had cash and cash equivalents , and marketable securities of $ 69,976,000 and working capital of $ 186,734,000 compared to december 31 , 2010 cash , cash equivalents and marketable securities of $ 83,129,000 and working capital of $ 181,244,000. we view our cash and cash equivalents and marketable securities as our principal measure of liquidity . our current ratio at december 31 , 2011 decreased to 5.1 to 1 from 5.5 to 1 at december 31 , 2010. this decrease resulted primarily from declines in our cash , cash equivalents and marketable securities and increases in accrued payroll , withheld payroll taxes expense primarily resulting from the timing of such payments at december 31 , 2011 from december 31 , 2010. our cash , cash equivalents and marketable securities declined at december 31 , 2011 from december 31 , 2010 , primarily due to the working capital investment required to support our 2011 revenue growth of 14.9 % and the payment of dividends to shareholders . the decrease was positively impacted by the increase in accounts and notes receivable resulting from our increase in revenues . the growth in accounts and notes receivable , net , exceeded the annual growth in revenues based on the revenue growth experienced in the latter portion of the year . on an historical basis , our operations have generally produced consistent cash flow and have required limited capital resources . we believe our current and near term cash flow positions will enable us to fund our continued anticipated growth . operating activities the net cash provided by our operating activities was $ 32,948,000 for the year ended december 31 , 2011. the principal sources of net cash flows from operating activities for 2011 were net income adjusted for non-cash charges to operations for bad debt provisions , stock-based compensation , depreciation and amortization .
