In 2010, new loan and lease volume increased due to higher retail truck sales ($313.4 million) as well as higher  average amounts financed per unit ($130.3 million). PFS increased its finance market share on new PACCAR trucks  to 28% in 2010 from 26% in the prior year. Decreased Financial Services revenues in 2010 primarily resulted from lower average earning asset balances in all  markets. Financial Services income before income taxes increased to $153.5 million in 2010 compared to $84.6  million in 2009. The increase of $68.9 million was primarily due to higher lease margin of $42.7 million and a  lower provision for losses on receivables of $29.8 million. The major factors for the change in interest and fees, interest and other borrowing expenses and finance margin for the  year ended December 31, 2010 are outlined in the table below:  The following table summarizes operating lease, rental and other income and depreciation and other expense.   • Lower average finance receivables in 2010 ($1.11 billion) resulted in $86.2 million of lower interest and fee  income. The lower finance receivables result from retail portfolio repayments exceeding new business volume as  well as a decrease in average wholesale financing ($322.1 million) due to lower dealer inventory balances.  • Average debt balances declined in 2010 by $1.35 billion resulting in $58.9 million of lower interest and other  borrowing expenses. The lower average debt balances reflect a lower level of funding needed for a smaller  financial services portfolio.  • Borrowing rates declined in 2010 due to lower market interest rates.  • Currency translation, primarily the stronger Australian and Canadian dollars, increased interest and fees by $9.0  million and interest and other borrowing expense by $4.0 million, respectively.
