In January 2010, the FASB deferred the provisions of this guidance primarily for entities with attributes of an investment company until the FASB and International Accounting Standards Board develop converged guidance on consolidation. This accounting guidance may otherwise have resulted in the consolidation of certain JCG investment products. The FASB is reconsidering the accounting guidance related to consolidation and an Exposure Draft is expected to be published during second quarter 2011. In January 2010, the FASB amended the previously issued guidance on fair value measurements, which will change the current disclosure requirement of Level 3 measurement activity from a net basis to a gross basis. The effective date of this guidance is the Company's fiscal year beginning January 1, 2011. The application of these provisions will not impact JCG's fair value measurements.</td></tr></table> NOTE 3  RECENT ACCOUNTING PRONOUNCEMENTS In June 2009, the Financial Accounting Standards Board ("FASB") issued new accounting guidance relatedfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringRepresents disclosure of any changes in an accounting principle, including a change from one generally accepted accounting principle to another generally accepted accounting principle when there are two or more generally accepted accounting principles that apply or when the accounting principle formerly used is no longer generally accepted.
