(14)  New Accounting Pronouncement

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)."  This ASU provides a single comprehensive revenue recognition model for all contracts with customers.  The principle for recognizing revenue is clarified as the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This ASU provides a five-step analysis to determine how revenue is recognized.  The provisions of the ASU are effective for interim and annual periods beginning after December 15, 2016.  The company is currently evaluating the impact of the pending adoption of this ASU on its financial statements.
