Special Dividend
Diamond Hill Investment Group, Inc. also announced a special dividend to be
declared on or around December 1, 2011. The Company anticipates that its board
of directors will approve a dividend of $5.00 per share to be paid prior to
December 31, 2011. It is also expected that the dividend will be characterized
as qualified dividend income and that no portion of the dividend will represent
a return of capital. Previous dividends declared by the Company included a
substantial return of capital; however, the board decided not to return any
capital in 2011. In determining the final amount of the dividend the Company
will consider fourth quarter operating results, 2012 capital requirements, and
a desire to not make a return of capital distribution.

Use of Supplemental Data as Non-GAAP Performance Measure
Net Operating Income After Tax

As supplemental information, we are providing performance measures that are
based on methodologies other than generally accepted accounting principles
("non-GAAP") for "Net Operating Income After Tax" that management uses as
benchmarks in evaluating and comparing the period-to-period operating
performance of Diamond Hill Investment Group, Inc. (the "Company") and
its subsidiaries.

The Company defines "net operating income after tax" as the Company's net
operating income less income tax provision excluding investment return and
the tax impact related to the investment return. The Company believes that
"net operating income after tax" provides a good representation of the
Company's operating performance, as it excludes the impact of investment
return on financial results. The amount of the investment portfolio and
market fluctuations on the investments can change significantly from
one period to another, which can distort the underlying earnings potential
of a company. We also believe "net operating income after tax" is an
important metric in estimating the value of an asset management business.
This non-GAAP measure is provided in addition to net income and net operating
income and is not a substitute for net income or net operating income and
may not be comparable to non-GAAP performance measures of other companies.


		 			  Three Months Ended September 30,
(in thousands, except per share data)		   2011		  2010
Net operating income, GAAP basis 		  $5,444     	 $4,199
Non-GAAP adjustments:
  Tax provision excluding impact
    of investment return 		 	   2,100 	  1,510
Net operating income after tax,
  non-GAAP basis 	 			   3,344	  2,689

Net operating income after tax per
  diluted share, non-GAAP basis    		   $1.11	  $0.97


		 			    Nine Months Ended September 30,
(in thousands, except per share data)		   2011		  2010
Net operating income, GAAP basis 		 $16,743     	$12,230
Non-GAAP adjustments:
  Tax provision excluding impact
    of investment return 		 	   6,315 	  4,438
Net operating income after tax,
  non-GAAP basis 	 			  10,428	  7,792

Net operating income after tax per
  diluted share, non-GAAP basis    		   $3.55	  $2.82

The tax provision excluding impact of investment return is calculated by
applying the tax rate from the actual tax provision to net operating
income.

The Company's management does not promote that investors consider the above
non-GAAP financial measures alone, or as a substitute for, financial
information prepared in accordance with GAAP.
