Regulatory Capital Requirements [Abstract]

Summary of actual capital amounts and ratios

Under its prompt corrective action regulations, the OCC is required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution. Such actions could have a direct material effect on an institution's financial statements. As stated above, the Bank has been classified as well capitalized for regulatory purposes, and therefore, these regulations do not apply. The following is a summary of actual capital amounts and ratios as of December 31, 2012 and 2011, for Trustco Bank:

(dollars in thousands)	As of December 31, 2012					Well			Adequately
	Amount		Ratio			Capitalized*			Capitalized*
Tier 1 (core) capital	$	349,580		8.05	%		5.00	%		4.00	%
Tier 1 risk-based capital		349,580		16.35			6.00			4.00
Total risk-based capital		376,565		17.62			10.00			8.00

(dollars in thousands)	As of December 31, 2011					Well			Adequately
	Amount		Ratio			Capitalized*			Capitalized*
Tier 1 (core) capital	$	335,759		7.90	%		5.00	%		4.00	%
