The Progressive Corporation and Subsidiaries
Notes to Consolidated Financial Statements
(unaudited)
Note 1 Basis of Presentation — The accompanying consolidated financial statements include the accounts of The Progressive Corporation and ARX Holding Corp. (ARX), and their respective wholly owned insurance and non-insurance subsidiaries and affiliates in which Progressive or ARX has a controlling financial interest. The Progressive Corporation owned 86.8% of the outstanding capital stock of ARX at March 31, 2019 and December 31, 2018 and 68.9% at March 31, 2018. The increase in Progressive’s ownership of ARX since March 31, 2018 is primarily due to the minority ARX shareholders exercising their rights to put a portion of their shares, including exercised stock options to Progressive pursuant to the ARX stockholders’ agreement. See Note 12 – Redeemable Noncontrolling Interest for further discussion.
The consolidated financial statements reflect all normal recurring adjustments that, in the opinion of management, were necessary for a fair statement of the results for the interim periods presented. The results of operations for the period ended March 31, 2019, are not necessarily indicative of the results expected for the full year. These consolidated financial statements and the notes thereto should be read in conjunction with Progressive’s audited financial statements and accompanying notes included in Exhibit 13 to our Annual Report on Form 10-K for the year ended December 31, 2018 (2018 Annual Report to Shareholders).
Other assets on the consolidated balance sheets include properties that are considered held for sale, if any. The fair value of these properties, less the estimated cost to sell them, was $52.6 million at March 31, 2019, $5.3 million at March 31, 2018, and $39.3 million at December 31, 2018.
Note 2 InvestmentsThe following tables present the composition of our investment portfolio by major security type, consistent with our classification of how we manage, monitor, and measure the portfolio. Our securities are reported in our Consolidated Balance Sheets at fair value. The changes in fair value for our fixed-maturity securities (other than hybrid securities) are reported as a component of accumulated other comprehensive income, net of deferred income taxes, in our Consolidated Balance Sheets. The net holding period gains (losses) reported below represent the inception-to-date changes in fair value. The changes in the net holding period gains (losses) between periods for the hybrid securities and equity securities are recorded as a component of net realized gains (losses) on securities in our Consolidated Statements of Comprehensive Income.
