what was the percent of the increase in the revenue from 2010 to 2011
the demand for property and casualty insurance generally rises as the overall level of economic activity increases and generally falls as such activity decreases , affecting both the commissions and fees generated by our brokerage business . the economic activity that impacts property and casualty insurance is described as exposure units , and is closely correlated with employment levels , corporate revenue and asset values . during 2011 we began to see some improvement in pricing ; however , we would still consider this to be a 2018 2018soft market , 2019 2019 which began in 2007 . in a soft market , premium rates flatten or decrease , along with commission revenues , due to increased competition for market share among insurance carriers or increased underwriting capacity . changes in premiums have a direct and potentially material impact on the insurance brokerage industry , as commission revenues are generally based on a percentage of the premiums paid by insureds . in 2011 , pricing showed signs of stabilization and improvement in both our retail and reinsurance brokerage product lines and we expect this trend to slowly continue into 2012 . additionally , beginning in late 2008 and continuing through 2011 , we faced difficult conditions as a result of unprecedented disruptions in the global economy , the repricing of credit risk and the deterioration of the financial markets . weak global economic conditions have reduced our customers 2019 demand for our brokerage products , which have had a negative impact on our operational results . risk solutions generated approximately 60% ( 60 % ) of our consolidated total revenues in 2011 . revenues are generated primarily through fees paid by clients , commissions and fees paid by insurance and reinsurance companies , and investment income on funds held on behalf of clients . our revenues vary from quarter to quarter throughout the year as a result of the timing of our clients 2019 policy renewals , the net effect of new and lost business , the timing of services provided to our clients , and the income we earn on investments , which is heavily influenced by short-term interest rates . we operate in a highly competitive industry and compete with many retail insurance brokerage and agency firms , as well as with individual brokers , agents , and direct writers of insurance coverage . specifically , we address the highly specialized product development and risk management needs of commercial enterprises , professional groups , insurance companies , governments , health care providers , and non-profit groups , among others ; provide affinity products for professional liability , life , disability .
