gain on land sales are derived from sales of undeveloped land owned by us . we pursue opportunities to dispose of land in markets with a high concentration of undeveloped land and in those markets where the land no longer meets our strategic development plans . the increase was partially attributable to a land sale to a current corporate tenant for potential future expansion . we recorded $ 424000 and $ 560000 of impairment charges associated with contracts to sell land parcels for the years ended december 31 , 2004 and 2003 , respectively . as of december 31 , 2004 , only one parcel on which we recorded impairment charges is still owned by us . we anticipate selling this parcel in the first quarter of 2005 . discontinued operations we have classified operations of 86 buildings as discontinued operations as of december 31 , 2004 . these 86 buildings consist of 69 industrial , 12 office and five retail properties . as a result , we classified net income from operations , net of minority interest , of $ 1.6 million , $ 6.3 million and $ 10.7 million as net income from discontinued operations for the years ended december 31 , 2004 , 2003 and 2002 , respectively . in addition , 41 of the properties classified in discontinued operations were sold during 2004 , 42 properties were sold during 2003 , two properties were sold during 2002 and one operating property is classified as held-for-sale at december 31 , 2004 . the gains on disposal of these properties , net of impairment adjustment and minority interest , of $ 23.9 million and $ 11.8 million for the years ended december 31 , 2004 and 2003 , respectively , are also reported in discontinued operations . for the year ended december 31 , 2002 , a $ 4.5 million loss on disposal of properties , net of impairment adjustments and minority interest , is reported in discontinued operations due to impairment charges of $ 7.7 million recorded on three properties in 2002 that were later sold in 2003 and 2004 . comparison of year ended december 31 , 2003 to year ended december 31 , 2002 rental income from continuing operations rental income from continuing operations increased from $ 652.8 million in 2002 to $ 689.3 million in 2003 . the following table reconciles rental income by reportable segment to our total reported rental income from continuing operations for the years ended december 31 , 2003 and 2002 ( in thousands ) : .
inn 2003 what was the percent of the total rental income by reportable segment that was sourced from retail
although our three reportable segments comprising rental operations ( office , industrial and retail ) are all within the real estate industry , they are not necessarily affected by the same economic and industry conditions . for example , our retail segment experienced high occupancies and strong overall performance during 2003 , while our office and industrial segments reflected the weaker economic environment for those property types . the primary causes of the increase in rental income from continuing operations , with specific references to a particular segment when applicable , are summarized below : 25cf during 2003 , in-service occupancy improved from 87.1% ( 87.1 % ) at the end of 2002 to 89.3% ( 89.3 % ) at the end of 2003 . the second half of 2003 was highlighted by a significant increase in the industrial portfolio occupancy of 2.1% ( 2.1 % ) along with a slight increase in office portfolio occupancy of 0.9% ( 0.9 % ) . 25cf lease termination fees totaled $ 27.4 million in 2002 compared to $ 16.2 million in 2003 . most of this decrease was attributable to the office segment , which recognized $ 21.1 million of termination fees in 2002 as compared to $ 11.8 million in 2003 . lease termination fees relate to specific tenants that pay a fee to terminate their lease obligations before the end of the contractual lease term . the high volume of termination fees in 2002 was reflective of the contraction of the business of large office users during that year and their desire to downsize their use of office space . the decrease in termination fees for 2003 was indicative of an improving economy and a more stable financial position of our tenants . 25cf during the year ended 2003 , we acquired $ 232 million of properties totaling 2.1 million square feet . the acquisitions were primarily class a office buildings in existing markets with overall occupancy near 90% ( 90 % ) . revenues associated with these acquisitions totaled $ 11.9 million in 2003 . in addition , revenues from 2002 acquisitions totaled $ 15.8 million in 2003 compared to $ 4.8 million in 2002 . this significant increase is primarily due to a large office acquisition that closed at the end of december 2002 . 25cf developments placed in-service in 2003 provided revenues of $ 6.6 million , while revenues associated with developments placed in-service in 2002 totaled $ 13.7 million in 2003 compared to $ 4.7 million in 25cf proceeds from dispositions of held for rental properties totaled $ 126.1 million in 2003 , compared to $ 40.9 million in 2002 . these properties generated revenue of $ 12.5 million in 2003 versus $ 19.6 million in 2002 . equity in earnings of unconsolidated companies equity in earnings represents our ownership share of net income from investments in unconsolidated companies . these joint ventures generally own and operate rental properties and hold land for development . these earnings decreased from $ 27.2 million in 2002 to $ 23.7 million in 2003 . this decrease is a result of the following significant activity: .
