administrative fees , which increased $ 5.8 million to $ 353.9 million , are generally offset by related operating expenses that are incurred to provide services to the funds and their investors . our largest expense , compensation and related costs , increased $ 18.4 million or 2.3% ( 2.3 % ) from 2007 . this increase includes $ 37.2 million in salaries resulting from an 8.4% ( 8.4 % ) increase in our average staff count and an increase of our associates 2019 base salaries at the beginning of the year . at december 31 , 2008 , we employed 5385 associates , up 6.0% ( 6.0 % ) from the end of 2007 , primarily to add capabilities and support increased volume-related activities and other growth over the past few years . over the course of 2008 , we slowed the growth of our associate base from earlier plans and the prior year . we also reduced our annual bonuses $ 27.6 million versus the 2007 year in response to unfavorable financial market conditions that negatively impacted our operating results . the balance of the increase is attributable to higher employee benefits and employment-related expenses , including an increase of $ 5.7 million in stock-based compensation . after higher spending during the first quarter of 2008 versus 2007 , investor sentiment in the uncertain and volatile market environment caused us to reduce advertising and promotion spending , which for the year was down $ 3.8 million from 2007 . occupancy and facility costs together with depreciation expense increased $ 18 million , or 12% ( 12 % ) compared to 2007 . we expanded and renovated our facilities in 2008 to accommodate the growth in our associates to meet business demands . other operating expenses were up $ 3.3 million from 2007 . we increased our spending $ 9.8 million , primarily for professional fees and information and other third-party services . reductions in travel and charitable contributions partially offset these increases . our non-operating investment activity resulted in a net loss of $ 52.3 million in 2008 as compared to a net gain of $ 80.4 million in 2007 . this change of $ 132.7 million is primarily attributable to losses recognized in 2008 on our investments in sponsored mutual funds , which resulted from declines in financial market values during the year. .
what percentage of tangible book value is made up of cash and cash equivalents and mutual fund investment holdings at december 31 , 2009?
