Adoption of this guidance will require us to present debt issuance costs, currently recorded in Other assets on the consolidated balance sheets, within Long-term debt.This guidance, which became effective on January 1, 2016, did not have any effect on our results of operations and financial condition.</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;font-weight:bold;">Accounting guidance not yet adopted</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;font-style:italic;font-weight:bold;">Revenue from Contracts with Customers</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;">In May 2014, the FASB issued an accounting standard that supersedes most existing revenue recognition guidance. The standard excludes from its scope the accounting for insurance contracts, leases, financial instruments, and certain other agreements that are governed under other GAAP guidance, but could affect the revenue recognition for certain of our claims management and risk control services. The updated guidance requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services. The standard is effective for interim and annual reporting periods beginning after December 15, 2017 and may be applied retrospectively or through a cumulative effect adjustment to retained earnings at the date of adoption. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The adoption of this guidance is not expected to have a material impact on our financial condition or results of operations. </font></div><div style="line-height:120%;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;font-style:italic;font-weight:bold;">Short-Duration Contracts</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;">In May 2015, the FASB issued guidance that requires additional disclosures for short-duration insurance contracts. New disclosure will be required to provide more information about initial claim estimates and subsequent adjustments to those estimates, the methodologies and judgments used to estimate claims, and the timing frequency, and severity of claims. The guidance is effective for public business entities for annual periods beginning after December 15, 2015 and interim periods within annual periods after December 15, 2016. The guidance requires a change in disclosure only and adoption of this guidance will have no impact on our financial condition or results of operations.</font></div></div> |
