Interest Rate Swaps, Caps and Net Investment Hedges
As of March 31, 2019, we have interest rate swap and interest rate cap agreements that were designated as cash flow hedges of interest rate risk. The currently effective interest rate swaps and caps hedge $2.2 billion of our approximately $5.6 billion of variable rate debt outstanding as of March 31, 2019. The Company also has designated a portion of its Euro denominated debt and 100% of its GBP denominated debt as net investment hedges. See Note 7 - Derivatives and Hedging Activities in “Item 1 - Notes to Unaudited Consolidated Financial Statements” for more information about the interest rate swaps, caps and net investment hedges.
Tax Receivable Agreements
As of March 31, 2019, we are party to several TRAs in which we have agreed to make payments to various parties of 85% of the federal, state, local and foreign income tax benefits realized by us as a result of certain tax deductions.
As discussed in Note 1 - Basis of Presentation and Summary of Significant Accounting Policies in Item 1 - Notes to Unaudited Consolidated Financial Statements,” Fifth Third exchanged its remaining 10.3 million Class B units of Worldpay Holding for shares of Worldpay, Inc. Class A common stock in March 2019.
As a result of the March 2019 Fifth Third exchange of units of Worldpay Holding, we recorded an estimated additional liability under the Fifth Third TRA of $327.9 million and an estimated additional deferred tax asset of $502.8 million associated with the increase in the tax basis. We recorded an estimated corresponding increase to paid-in-capital of $174.9 million for the difference in the TRA liability and the related deferred tax asset.
For more information on the TRAs, see Note 8 - Tax Receivable Agreements in the Notes to Consolidated Financial Statements of the Company’s 2018 Form 10-K filed on February 26, 2019.
There have been no significant changes to contractual obligations and commitments compared to those disclosed in our Annual Report on Form 10-K as of December 31, 2018 filed with the SEC on February 26, 2019.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based upon our audited consolidated financial statements in our 2018 Form 10-K, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate our critical estimates giving consideration to a combination of factors, including historical experience, current conditions and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.
Except for the adoption of Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) and ASU 2017-12, Derivatives and Hedging (Topic 815) on January 1, 2019 as discussed in Note 3 - Leases and Note 7 - Derivatives and Hedging Activities in “Item 1 - Notes to Unaudited Consolidated Financial Statements,” we have not adopted any new critical accounting policies, have not changed any critical accounting policies and have not changed the application of any critical accounting policies from the year ended December 31, 2018. Our critical accounting policies and estimates are described fully within Management’s Discussion and Analysis of Financial Condition and Results of Operations included within our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 26, 2019.
