risk factors. operating overview new and used vehicle revenues include sales to retail customers and to leasing companies providing consumer automobile leasing . we generate finance and insurance revenues from sales of third-party extended service contracts , sales of third-party insurance policies , commissions relating to the sale of finance and lease contracts to third parties and the sales of certain other products . service and parts revenues include fees paid for repair , maintenance and collision services , and the sale of replacement parts and other aftermarket accessories . 24 our gross profit tends to vary with the mix of revenues we derive from the sale of new vehicles , used vehicles , finance and insurance products , and service and parts transactions . our gross profit varies across product lines , with vehicle sales usually resulting in lower gross profit margins and our other revenues resulting in higher gross profit margins . factors such as inventory and vehicle availability , customer demand , consumer confidence , unemployment , general economic conditions , seasonality , weather , credit availability , fuel prices and manufacturers ' advertising and incentives also impact the mix of our revenues , and therefore influence our gross profit margin . aggregate gross profit increased $ 251.1 million , or 14.3 % , during 2012 compared to 2011. the increase in gross profit is largely attributable to a 9.9 % increase in same store retail revenue . our retail gross margin percentage declined from 16.8 % during 2011 to 16.3 % during 2012 , due primarily to lower gross margin on new and used vehicle retail sales as well as an increase in the percentage of our revenues generated by vehicle sales , which carry a lower gross margin than other parts of our business . our selling expenses consist of advertising and compensation for sales personnel , including commissions and related bonuses . general and administrative expenses include compensation for administration , finance , legal and general management personnel , rent , insurance , utilities , and other expenses . as the majority of our selling expenses are variable , and we believe a significant portion of our general and administrative expenses are subject to our control , we believe our expenses can be adjusted over time to reflect economic trends . floor plan interest expense relates to financing incurred in connection with the acquisition of new and used vehicle inventories that is secured by those vehicles . other interest expense consists of interest charges on all of our interest-bearing debt , other than interest relating to floor plan financing . the cost of our variable rate indebtedness is based on the prime rate , defined london interbank offered rate ( libor ) , the bank of england base rate , the finance house base rate , or the euro interbank offered rate . our floor plan interest expense has increased during 2012 as a result of higher applicable interest rates due to the impact of interest rate swap transactions that began in 2012 , as well as an increase in the amounts outstanding under floor plan arrangements . our other interest expense has increased during 2012 due to the increase in borrowings under our revolving credit agreements in the u.s. and u.k. due to significant acquisitions in 2012. equity in earnings of affiliates represents our share of the earnings from our investments in joint ventures and other non-consolidated investments , including ptl . because ptl is engaged in different businesses than we are , its operating performance may vary significantly from ours . the future success of our business is dependent upon , among other things , general economic and industry conditions , our ability to consummate and integrate acquisitions , the level of vehicle sales in the markets where we operate , our ability to increase sales of higher margin products , especially service and parts services , our ability to realize returns on our significant capital investment in new and upgraded dealership facilities and the return realized from our investments in various joint ventures and other non-consolidated investments . see item 1a  risk factors and forward-looking statements below . critical accounting policies and estimates the preparation of financial statements in accordance with accounting principles generally accepted in the united states of america requires the application of accounting policies that often involve making estimates and employing judgments . such judgments

determine that modifications in assumptions and estimates are required , which may result in a material change in our results of operations or financial position . the following are the accounting policies applied in the preparation of our financial statements that management believes are most dependent upon the use of estimates and assumptions . 25 revenue recognition vehicle , parts and service sales we record revenue when vehicles are delivered and title has passed to the customer , when vehicle service or repair work is completed and when parts are delivered to our customers . sales promotions that we offer to customers are accounted for as a reduction of revenues at the time of sale . rebates and other incentives offered directly to us by manufacturers are recognized as a reduction of cost of sales . reimbursements of qualified advertising expenses are treated as a reduction of selling , general and administrative expenses . the amounts received under certain manufacturer rebate and incentive programs are based on the attainment of program objectives , and such earnings are recognized either upon the sale of the vehicle for which the award was received , or upon attainment of the particular program goals if not associated with individual vehicles . story_separator_special_tag revenues new vehicle retail sales revenue increased $ 1.14 billion , or 20.3
