| RECENT ACCOUNTING STANDARDS:                            | RECENT ACCOUNTING STANDARDS:In December 2011, the FASB amended disclosure concerning offsetting assets and liabilities. The amendments in the update requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments. 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.  In January 2013, the FASB issued clarifying guidance related to the amended disclosure requirements concerning offsetting assets and liabilities which had previously been issued in December 2011.  The guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The Company is currently evaluating the prospective effects, if any, of adopting this guidance.  In October 2012, the FASB issued technical corrections and improvements, which include revisions to prior guidance on numerous topics, including Convertible Debentures. The effective date of these revisions is for fiscal years beginning after December 15, 2012. The Company is currently evaluating the prospective effects, if any, of adopting this guidance.  In February 2013, the FASB amended its guidance related to the reporting of amounts reclassified out of accumulated other comprehensive income.    The amendments are effective prospectively for reporting periods beginning after December 15, 2012.   The Company is currently evaluating the prospective effects, if any, of adopting this guidance.In July 2013, the FASB updated its guidance with respect to the presentation of unrecognized tax benefits.  The guidance is effective for reporting periods beginning after December 15, 2013, with early adoption permitted.   The Company has consistently reported in compliance with this updated guidance. |
