decreased in electronics , as discussed in more detail below . at december 31 , 2008 , our total backlog was $ 330.5 million compared to $ 310.8 million at december 31 , 2007. backlog consisted of product and service and components backlog of unfilled orders of $ 273.5 million and $ 57.0 million , respectively , at december 31 , 2008 compared to $ 256.1 million and $ 54.7 million , respectively , at december 31 , 2007. outlook for 2009 in light of the difficult global economic environment , including unprecedented volatility in foreign exchange markets , forecasting for all of 2009 is particularly challenging . after achieving revenue growth of 23.6 % in 2007 compared to 2006 , and 1.1 % in 2008 compared with 2007 , it is likely that we will experience a decline in revenue in 2009. we expect electronics revenue to continue to be depressed in 2009. the depressed electronics revenue may not be offset by any potential growth in our other markets for 2009. our backlog of unfilled orders as we enter the year is at record levels , and historically we have not experienced significant volumes of order cancellations . as result , revenues in the first half of 2009 will likely be approximately equal to , or only somewhat below , 2008 levels . if global economic conditions continue to be poor and this affects total new orders in the first half of 2009 , our revenues could decline more significantly in the second half of 2009. a significant portion of our revenue and expenses are denominated in euros . if the u.s. dollar continues to strengthen as it did in the second half of 2008 , then our reported revenue would decline or grow more slowly . at the same time , our expenses would decline even more rapidly , improving operating income . conversely , if the euro strengthens against the u.s. dollar , revenue would increase and expenses would increase more rapidly , reducing operating income . we are taking steps to create more naturally hedged 28 positions , but , for 2009 , the impact of currency movements are expected to generally be as described above . historically , our research and industry business has generally held up well in economic downturns , turning in flat revenue or even modest growth , as governments , institutions and corporations globally invest in research and product development . depending on the severity of the current downturn or whether there are significant cuts in government spending , we could see a contraction in our research and industry business in general . in addition , the smaller industrial portion of this segment could be negatively impacted by general economic weakness . overall , we believe the global reach of our products and the multi-year budget cycles of many of our customers will provide a measure of downside protection . presently , we expect continued growth in our life sciences business in 2009 , although it will vary from quarter to quarter and we lack visibility into the second half of 2009. this is an emerging , research-oriented market for us , and we expect our revenue to continue to be positively affected by the introduction of the titan krios tem in 2008. the electronics segment , which includes semiconductor and data storage customers , is in the midst of a severe industry-wide downturn . revenue for this segment is expected to decline in 2009. despite the difficult environment , we believe we have the potential to demonstrate better performance than the semiconductor capital equipment industry as a whole , because of increased demand for our higher-resolution images as manufacturers move to smaller line widths and new processes , among other factors . demand for service of our products is expected to grow modestly as our installed base of products grows . however , the current economic environment will most likely temper revenue growth in this segment . we believe we hold leadership positions , both technologically and in the markets in which we compete , with our tem and dualbeam products . story_separator_special_tag the discussions related to the proposed transaction were terminated in the first quarter of 2006. amortization of purchased technology amortization of purchased technology was $ 1.8 million in 2008 , $ 1.8 million in 2007 and $ 2.0 million in 2006. our purchased technology balance at december 31 , 2008 was $ 1.3 million and current amortization of purchased technology is approximately $ 0.5 million per quarter , which could increase if we acquire additional technology . asset impairment we had no asset impairment charges in 2008 or 2007. asset impairment charges of $ 0.5 million in 2006 were primarily for the write-off of the remaining costs related to the abandonment of our erp system , which were incurred during the first quarter of 2006. restructuring , reorganization , relocation and severance the $ 4.3 million of restructuring , reorganization , relocation and severance expense in 2008 related to our april 2008 restructuring plan . we expect to incur approximately an additional $ 2.7 to $ 4.7 million related to the implementation of this plan in 2009 , for total charges of between $ 7.0 million to $ 9.0 million . we expect some portion of these expenses will fall within sfas no . 146 ,  accounting for costs associated with exit or disposal activities . some of the expenses , however , may not fall within the specific requirements of sfas no . 146. we are undertaking the restructuring with the aim of improving the efficiency of our operations and improving the currency balance in our supply chain so that more of our 35 costs are denominated in dollar or dollar-linked currencies . these actions are expected to reduce operating expenses , improve our factory utilization and help offset the effect of a weakened dollar on our cost of goods sold . the net $ 0.3 million expense reversal of restructuring , reorganization , relocation and severance costs in 2007 related to favorable buyouts of our peabody lease , offset by changes in estimates incorporated into our restructuring accrual related to our ability to sublease certain abandoned facilities under lease . restructuring , reorganization , relocation and severance in 2006 included a charge of $ 3.3 million for facilities and severance charges related to the closure of certain of our european field offices , closure of a research and development facility in tempe , arizona , as well as residual costs related to the peabody , massachusetts plant closure and the downsizing of the related semiconductor businesses . effective april 1 , 2006 , our chairman , president and chief executive officer ( ceo ) was terminated . our ceo was a party to an existing executive severance agreement dated february 1 , 2002. in accordance with this agreement , in the first quarter of 2006 , we recorded a charge of $ 9.3 million , of which $ 2.2 million related to the cash severance payments and $ 7.1 million related to the non-cash expense associated with the fair market value of modified stock options . for information regarding the related accrued liability , see note 14 of notes to consolidated financial statements . other income ( expense ) , net other income ( expense ) items include interest income , interest expense , foreign currency gains and losses and other miscellaneous items . interest income represents interest earned on cash and cash equivalents , investments in marketable securities . interest income was $ 14.4 million in 2008 , $ 22.4 million in 2007 and $ 13.2 million in 2006. the decrease in 2008 compared to 2007 was primarily due to a decrease in our invested balances , due to $ 45.9 million of payments in the first quarter of fiscal 2008 to repay the remaining balance on our 5.5 % convertible notes and $ 149.4 million of payments , including premiums , in the second and third quarters of fiscal 2008 to repay principal on our $ 150.0 million zero coupon convertible notes and much lower interest rates . the increase in 2007 compared to 2006 resulted from an increase in our invested balances , primarily due to cash generated by operations , as well as from the net proceeds from our sale of $ 115.0 million principal amount of 2.875 % convertible debt in may 2006. interest expense for 2008 , 2007 and 2006 included interest expense related to our $ 115.0 million principal amount of 2.875 % convertible notes . interest expense in 2007 and 2006 also included interest related to our 5.5 % convertible notes issued in august 2001 , which were repaid in full in january 2008. the amortization of capitalized note issuance costs related to our convertible note issuances is also included as a component of interest expense in all years . interest expense in 2008 included $ 0.2 million of premiums and commissions paid on the repurchase of the remaining $ 45.9 million of our 5.5 % convertible notes as well as the write-off of $ 0.1 million of related deferred note issuance costs and $ 0.4 million of premiums and commissions paid on the repurchase of $ 148.9 million principal amount of our $ 150.0 million zero coupon convertible notes as well as the write-off of $ 0.2 million of related deferred note issuance costs . interest expense in 2006 included premiums and commissions paid on the repurchase of a portion of our 5.5 % convertible subordinated notes as well as the write-off of deferred note issuance costs totaling $ 0.5 million . 36 assuming no additional note repurchases , amortization of our remaining convertible note issuance costs will total approximately $ 0.1 million per quarter through the second quarter of 2013. other , net primarily consists of foreign currency gains and losses on
