Using an extensive database of initial bank loans issued to US firms from 1998-2010 we find that the social network centrality of the chief financial officer (CFO) affects the cost and structure of firm loan contracting. Firms with more central CFOs issue new loans with lower spreads and fewer covenant restrictions than do firms with less central CFOs. The effects are increasing in firm opacity; firms with more intangible assets, R&D expense, and accruals benefit more from higher CFO centrality. More favorable loan terms to firms with central CFOs do not appear to be inappropriate as there is no evidence that these firms underperform subsequent to loan origination. CFO centrality remains an important determinant in loan spreads and covenant structure when controlling for firm governance, CEO centralities, and direct relationships between borrowers and lenders.
