technology and communications expense in 2003 , technology and communications expense was 11% ( 11 % ) above the prior-year level . the increase was primarily due to a shift in expenses : costs that were previously associated with compensation and other expenses shifted , upon the commence- ment of the ibm outsourcing agreement , to technology and communications expense . also contributing to the increase were higher costs related to software amortization . for a further dis- cussion of the ibm outsourcing agreement , see support units and corporate on page 44 of this annual report . other expense other expense in 2003 rose slightly from the prior year , reflecting higher outside services . for a table showing the components of other expense , see note 8 on page 96 of this annual report . surety settlement and litigation reserve the firm added $ 100 million to the enron-related litigation reserve in 2003 to supplement a $ 900 million reserve initially recorded in 2002 . the 2002 reserve was established to cover enron-related matters , as well as certain other material litigation , proceedings and investigations in which the firm is involved . in addition , in 2002 the firm recorded a charge of $ 400 million for the settlement of enron-related surety litigation . merger and restructuring costs merger and restructuring costs related to business restructurings announced after january 1 , 2002 , were recorded in their relevant expense categories . in 2002 , merger and restructuring costs of $ 1.2 billion , for programs announced prior to january 1 , 2002 , were viewed by management as nonoperating expenses or 201cspecial items . 201d refer to note 8 on pages 95 201396 of this annual report for a further discussion of merger and restructuring costs and for a summary , by expense category and business segment , of costs incurred in 2003 and 2002 for programs announced after january 1 , 2002 . provision for credit losses the 2003 provision for credit losses was $ 2.8 billion lower than in 2002 , primarily reflecting continued improvement in the quality of the commercial loan portfolio and a higher volume of credit card securitizations . for further information about the provision for credit losses and the firm 2019s management of credit risk , see the dis- cussions of net charge-offs associated with the commercial and consumer loan portfolios and the allowance for credit losses , on pages 63 201365 of this annual report . income tax expense income tax expense was $ 3.3 billion in 2003 , compared with $ 856 million in 2002 . the effective tax rate in 2003 was 33% ( 33 % ) , compared with 34% ( 34 % ) in 2002 . the tax rate decline was principally attributable to changes in the proportion of income subject to state and local taxes . compensation expense compensation expense in 2003 was 6% ( 6 % ) higher than in the prior year . the increase principally reflected higher performance-related incentives , and higher pension and other postretirement benefit costs , primarily as a result of changes in actuarial assumptions . for a detailed discussion of pension and other postretirement benefit costs , see note 6 on pages 89 201393 of this annual report . the increase pertaining to incentives included $ 266 million as a result of adopting sfas 123 , and $ 120 million from the reversal in 2002 of previously accrued expenses for certain forfeitable key employ- ee stock awards , as discussed in note 7 on pages 93 201395 of this annual report . total compensation expense declined as a result of the transfer , beginning april 1 , 2003 , of 2800 employees to ibm in connection with a technology outsourcing agreement . the total number of full-time equivalent employees at december 31 , 2003 was 93453 compared with 94335 at the prior year-end . occupancy expense occupancy expense of $ 1.9 billion rose 19% ( 19 % ) from 2002 . the increase reflected costs of additional leased space in midtown manhattan and in the south and southwest regions of the united states ; higher real estate taxes in new york city ; and the cost of enhanced safety measures . also contributing to the increase were charges for unoccupied excess real estate of $ 270 million ; this compared with $ 120 million in 2002 , mostly in the third quarter of that year. .
