       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;In December&amp;#160;2009, the FASB issued Accounting Standards Update (ASU)&amp;#160;No.&amp;#160;2009-17,
   &amp;#8220;Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with
   Variable Interest Entities.&amp;#8221; ASU No.&amp;#160;2009-17 changes how a company determines when an entity
   that is insufficiently capitalized or is not controlled through voting should be consolidated.
   The determination of whether a company is required to consolidate an entity is based on, among
   other things, an entity&amp;#8217;s purpose and design and a company&amp;#8217;s ability to direct the activities
   of the entity that most significantly impact the entity&amp;#8217;s economic performance. This statement
   is effective for the Company beginning in the first quarter of fiscal 2011 (October&amp;#160;1, 2010).
   The Company is assessing the potential impact that the adoption of ASU No.&amp;#160;2009-17 will have
   on its consolidated financial condition and results of operations.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;In October&amp;#160;2009, the FASB issued ASU No.&amp;#160;2009-13, &amp;#8220;Revenue Recognition (Topic 605):
   Multiple-Deliverable Revenue Arrangements &amp;#8212; a consensus of the FASB Emerging Issues Task
   Force.&amp;#8221; ASU No.&amp;#160;2009-13 establishes the accounting and reporting guidance for arrangements
   under which a vendor will perform multiple revenue-generating activities. Specifically, this
   ASU addresses how to separate deliverables and how to measure and allocate arrangement
   consideration to one or more units of accounting. This guidance will be effective for the
   Company beginning in the first quarter of fiscal 2011 (October&amp;#160;1, 2010) and, when adopted,
   will change the Company&amp;#8217;s accounting treatment for multiple-element revenue arrangements on a
   prospective basis.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;In December&amp;#160;2008, the FASB issued guidance on an employer&amp;#8217;s disclosures about plan assets of a
   defined benefit pension plan. The guidance requires enhanced transparency surrounding the
   types of plan assets and associated risks, as well as disclosure of information about fair
   value measurements of plan assets. This guidance is included in ASC 715, &amp;#8220;Compensation -
   Retirement Benefits,&amp;#8221; and is effective for the Company for the fiscal year ending September
   30, 2010. The adoption of this guidance will have no impact on the Company&amp;#8217;s consolidated
   financial condition and results of operations.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;In December&amp;#160;2007, the FASB issued guidance changing the accounting for business combinations
   in a number of areas including the treatment of contingent consideration, preacquisition
   contingencies, transaction costs, in-process research and development and restructuring costs.
   In addition, under this guidance changes in an acquired entity&amp;#8217;s deferred tax assets and
   uncertain tax positions after the measurement period will impact income tax expense. This
   guidance is included in ASC 805, &amp;#8220;Business Combinations,&amp;#8221; and is effective for the Company in
   the first quarter of fiscal 2010 (October&amp;#160;1, 2009). This guidance changes the Company&amp;#8217;s
   accounting treatment for business combinations on a prospective basis.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;In December&amp;#160;2007, the FASB issued guidance changing the accounting and reporting for minority
   interests, which will be recharacterized as noncontrolling interests and classified as a
   component of equity. This new consolidation method changes the accounting for transactions
   with minority interest holders. This guidance is included in ASC 810, &amp;#8220;Consolidation,&amp;#8221; and is
   effective for fiscal years beginning after December&amp;#160;15, 2008. This guidance is effective for
   the Company in the first quarter of fiscal 2010 (October&amp;#160;1, 2009). The adoption of this
   guidance has had no material impact on the Company&amp;#8217;s consolidated financial condition and
   results of operations. Refer to Note 14, &amp;#8220;Equity Attributable to Johnson Controls, Inc. and
   Noncontrolling Interests&amp;#8221; for further discussion.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;In September&amp;#160;2006, the FASB issued guidance that defines fair value, establishes a framework
   for measuring fair value and expands disclosures about fair value measurements. This guidance
   also establishes a fair value hierarchy that prioritizes information used in developing
   assumptions when pricing an asset or liability. This guidance is included in ASC 820, &amp;#8220;Fair
   Value Measurements and Disclosures.&amp;#8221; The Company adopted this guidance effective October&amp;#160;1,
   2008. In February&amp;#160;2008, the FASB delayed the effective date of this guidance for nonfinancial
   assets and nonfinancial liabilities that are recognized or disclosed in the financial
   statements on a nonrecurring basis to fiscal years beginning after November&amp;#160;15, 2008. The
   provisions of this guidance for nonfinancial assets and nonfinancial liabilities are effective
   for the Company in the first quarter of fiscal 2010 (October&amp;#160;1, 2009) and will be applied
   prospectively to fair value assessments such as the Company&amp;#8217;s goodwill impairment analysis.&lt;/td&gt;
