Depreciation and amortization expenses. It increased by 9.3% from Rp2,818.7 billion in 2004 to Rp3,080.2 billion in 2005 primarily due to increase in fixed assets mainly cellular business related fixed assets procured in 2005.
Personnel costs. We could manage personnel costs hence it only increased by 4.7% in 2005 which was lower than the percentage increase of operating revenues and overall operating expenses.
Compensation expenses to telecommunications carriers and service providers. It decreased by Rp104.9 billion from Rp513.4 billion in 2004 to Rp408.4 billion in 2005 primarily due to increased delivery of IDD traffic through our own network and the decrease in incoming and outgoing traffics from other local operators.
Maintenance expenses. It increased by 29.8% year-on-year, from Rp. 473.4 billion in 2004 to Rp. 614.6 billion in 2005 primarily due to increased maintenance expenses associated with our increased capital expenditure on cellular equipment, primarily base transceiver stations and additional cellular equipment installed during such periods.
Administration and general expenses. It increased by 28.6% year-on-year, from Rp. 471.3 billion in 2004 to Rp. 606.0 billion in 2005 primarily due to increase in provision for doubtful account amounting to Rp. 127.4 billion. The increase of Rp 127.4 billion of provision in 2005 was a result of the standardization of the Companys accounting policy for provision for doubtful accounts effective since 2004 following the merger of Satelindo and IM3 into Indosat, as well as due to the additional provision provided for cellular postpaid subscribers.
