Recently Issued Accounting Guidance [Abstract]
Recently Issued Accounting Guidance	12. Recently Issued Accounting Guidance—In December 2011, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. In response to concerns raised by stakeholders that reclassifications of items out of accumulated other comprehensive income would be difficult for preparers and may add unnecessary complexity to financial statements, they asked the Board to defer the effective date. The other 2 items presented in FASB issued ASU NO. 2011-05 is still applicable pertaining to (1) eliminate the option to present components of other comprehensive income ("OCI") as part of the statement of changes in stockholders' equity, and (2) require presentation of each component of net income and each component of OCI (and their respective totals) either in a single continuous statement or in two separate (but consecutive) statements. The amendments made by ASU No. 2011-12 are effective for fiscal years (and interim periods within such years) beginning after December 15, 2011. AVD adopted this guidance effective March 31, 2012 and has used a single continuous statement approach. In December 2011, FASB issued ASU No. 2011-11, Balance Sheet. In response to the requests from financial users for comparability on the differences that resulted in offsetting assets and liabilities under U.S. generally accepted accounting principles (U.S. GAAP) requirements versus International Financial Reporting Standards ("IFRS") requirements, the Financial Accounting Standards Board ("FASB") and the International Accounting Standards Board, ("IASB") jointly issued this update to enhance current disclosures. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of IFRS. The amendments in this Update affect all entities that have financial instruments and derivative instruments that are either (1) offset in accordance with either Section 210-20-45 or Section 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement. The requirements amend the disclosure requirements on offsetting in Section 210-20-50. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. AVD is evaluating the effect of this guidance but does not expect it to have a significant impact on its financial statements. In June 2011, FASB issued Accounting Standards Updates ASU No. 2011-05, Presentation of Comprehensive Income, to amend FASB Codification Topic 220, Comprehensive Income. The objective of this update is to (1) eliminate the option to present components of other comprehensive income ("OCI") as part of the statement of changes in stockholders' equity, (2) require presentation of each component of net income and each component of OCI (and their respective totals) either in a single continuous statement or in two separate (but consecutive) statements, and (3) require presentation of reclassification adjustments on the face of the statement. The amendments made by ASU No. 2011-05 should be applied retrospectively and become effective for fiscal years (and interim periods within such years) beginning after December 15, 2011, with early adoption permitted. AVD adopted this guidance effective March 31, 2012 and has used a single continuous statement approach. In May 2011, the FASB issued an update to Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurement, intended to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. and international standards. The guidance does not purport to change the scope of transactions in which fair value measurement is required to be applied. This update explains how to measure fair value. It does not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financial reporting. The amendments set forth in FASB ASU No. 2011-04 are to be applied prospectively and are effective during interim and annual periods beginning after December 15, 2011, for public companies. AVD adopted this guidance on January 1, 2012, and its adoption did not significantly impact the Company's consolidated financial statements.
