The majority of the Company’s cash equivalent investments and its interest rate swap contracts are with investment grade commercial banks. Accounts receivable balances deemed to be collectible from customers have limited concentration of credit risk due to our diverse customer base and geographic dispersion. The Company’s pension reinsurance asset (see Note 13 — Employee Benefits) is maintained with a large international insurance company that was rated investment grade as of December 31, </font><font style="font-family:inherit;font-size:10pt;">2015</font><font style="font-family:inherit;font-size:10pt;">.</font></div></div>

These rules and their potential impact are discussed below: </font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Business Combinations </font><font style="font-family:inherit;font-size:10pt;">— In September 2015, the FASB issued Accounting Standards Update (ASU) 2015-16, "</font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments</font><font style="font-family:inherit;font-size:10pt;">" ("ASU No. 2015-16"). ASU No. 2015-16 requires the recognition of adjustments to business combination provisional amounts, that are identified during the measurement period, in the reporting period in which the adjustments are determined. The effects of the adjustments to provisional amounts on depreciation, amortization or other income effects should be recognized in current-period earnings as if the accounting had been completed at the acquisition date. Disclosure of the portion of the adjustment recorded in current-period earnings that would have been reported in prior reporting periods if the adjustment to the provisional amounts had been recognized at the acquisition date is also required. The rule is to be applied retrospectively and is effective for Gartner on January 1, 2016. ASU No. 2015-16 will not have an impact on the Company’s consolidated financial statements at the date of adoption. However, ASU No. 2016-16 could have an impact on the Company's consolidated financial statements in the future if a transaction occurs within the scope of the rule. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Debt Issuance Cost Presentation </font><font style="font-family:inherit;font-size:10pt;">— In April 2015, the FASB issued ASU No. 2015-03, “</font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Simplifying the Presentation of Debt Issuance Costs</font><font style="font-family:inherit;font-size:10pt;">,” which amends the current presentation of debt issuance costs in the financial statements. ASU No. 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, instead of a deferred asset. The amendment is to be applied retrospectively and is effective for Gartner on January 1, 2016. The adoption of the new guidance will likely result in some minor presentation changes to the Company’s consolidated balance sheet and disclosures. </font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue Recognition </font><font style="font-family:inherit;font-size:10pt;">— In May 2014, the FASB issued ASU No. 2014-09, "</font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers</font><font style="font-family:inherit;font-size:10pt;">" ("ASU No. 2014-09"). ASU No. 2014-09 and a related amendment is intended to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in revenue recognition requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. ASU No. 2014-09 is effective for Gartner on January 1, 2018. We continue to evaluate the impact of ASU No. 2014-09. </font></div></div>

These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of fees receivable, goodwill, intangible assets, and other long-lived assets, as well as tax accruals and other liabilities. In addition, estimates are used in revenue recognition, income tax expense, performance-based compensation charges, depreciation, and amortization. Management believes its use of estimates in the accompanying consolidated financial statements to be reasonable.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Management continuously evaluates and revises its estimates using historical experience and other factors, including the general economic environment and actions it may take in the future. Management adjusts these estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time. As a result, differences between our estimates and actual results could be material and would be reflected in the Company’s consolidated financial statements in future periods.</font></div></div>
