New Accounting Pronouncement or Change in Accounting Principle, Description	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;text-decoration:underline;">Leases - February 2016 (amended through December 2018)</font><font style="font-family:inherit;font-size:10pt;font-style:italic;">:</font><font style="font-family:inherit;font-size:10pt;"> The amended guidance is intended to increase transparency and comparability among organizations by requiring additional disclosures to reflect the significance of an entity’s leasing arrangements. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Many long-term operating leases, including agreements relating to real estate, will be recorded on the balance sheet as an ROU asset with a corresponding lease liability, which will be amortized using the effective interest rate method as payments are made. Certain leases embedded in other arrangements, such as service and supplier contracts, may be accounted for separately by allocating payments between lease and non-lease components.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The new standard provides a number of optional practical expedients in transition. We currently expect to elect the package of practical expedients, which permits us to carryforward our prior conclusions about lease identification, lease classification and initial direct costs. Additionally, we currently expect to adopt the practical expedient that allows comparative periods to be reported under current lease accounting guidance consistent with previously issued financial statements. We also do not currently expect to record leases on the balance sheet that at the commencement date have a lease term of twelve months or less. </font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">While we continue to assess all of the effects of adoption, we currently believe the most significant effects relate to the recognition of new ROU assets and lease liabilities on our Balance Sheet for our real estate operating leases and providing significant new disclosures about our leasing activities. These operating leases will be recognized on a straight-line basis in rent expense. Additionally, we continue to evaluate the impact of the adoption on our existing failed sale-leaseback transactions. The Company expects the accounting for lease agreements where the Company is a lessor to be accounted for in the same manner as those agreements are accounted for under current accounting guidance.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We will adopt the new standard on January 1, 2019 and have elected to apply the guidance as of the adoption date. Consequently, financial information will not be updated, and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019.</font></div></div>
