REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
 
 
To the Board of Directors a nd Share holders of A pplied  Indus tria l Tec hnol ogies , Inc.  
Clevela nd, Ohio 
We have audited the internal control over financial reporting of Applied Industrial Technologies, Inc. and subsidiaries (the “Company”) 
as of June 30, 2012, based on criteria established in Internal Control — Integrated Framework  issued by the Committee of Sponsoring 
Organizations of the Treadway Commission.  The Company’s management is responsible for maintaining  effective internal c ontrol over 
financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the a ccompanying 
Management’s Report on Internal Control Over Financial Reporting.  Our responsibility is to express an opinion on the Company’s 
internal control over financial reporting based on our audit. 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those 
standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over 
financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal control over 
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of 
internal control based on the assessed risk, and performing such other proce dures as we considered necessary in the circumstances.  
We believe that our audit provides a reasonable basis for our opinion. 
A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal 
executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, 
management, and other personnel to provide reasonable assurance regarding the reliability of f inancial reporting and the preparation 
of financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control 
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that , in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that 
transaction s are recorded as necessary to permit preparati on of financial statements in accordance with generally accepted acc ounting 
principles, and that receipts and expenditures of the company are bei ng made only in accordance with authorizations of management 
and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material eff ect on the financial statements. 
Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis.  
Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are s ubject to 
the risk that the con trols may become inadequate because of changes in conditions, or that the degree of compliance with the policies 
or procedures may deteriorate. 
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2012, 
based on the criteria established in Internal Control — Integrated Framework  issued by the Committee of Sponsoring Organizations of 
the Treadway Commission.
