The Progressive Corporation Debt

Excluding the other debt instruments, all of the outstanding debt was issued by The Progressive Corporation, the ultimate holding company. The holding company debt includes amounts that were borrowed and contributed to the capital of its insurance subsidiaries or used, or made available for use, for other business purposes. Fair values for these debt instruments are obtained from external sources. There are no restrictive financial covenants or credit rating triggers on The Progressive Corporation debt.

Interest on all debt issued by The Progressive Corporation is payable semiannually at the stated rates. However, the 6.70% Fixed-to-Floating Rate Junior Subordinated Debentures due 2067 (the “6.70% Debentures”) will only bear interest at this fixed annual rate through June 14, 2017. Thereafter, the 6.70% Debentures will bear interest at an annual rate equal to the three-month London Interbank Offered Rate (LIBOR) plus 2.0175%, and interest will be payable quarterly until the 6.70% Debentures are redeemed or retired.

Except for the 6.70% Debentures, all remaining principal on the Senior Notes is due at the maturity stated in the tables above. The Senior Notes are redeemable, in whole or in part, at any time; however, the redemption price will equal the greater of the principal amount of the Senior Notes or a “make whole” amount calculated by reference to the present values of remaining scheduled principal and interest payments under the Senior Notes. Commencing on June 15, 2017, on each interest payment date, we have the right to redeem the 6.70% Debentures at par. If not previously redeemed, the 6.70% Debentures will become due on June 15, 2037, the scheduled maturity date, but only to the extent that we have received sufficient net proceeds from the sale of certain qualifying capital securities. The Progressive Corporation must use its commercially reasonable efforts, subject to certain market disruption events, to sell enough qualifying capital securities to permit repayment of the 6.70% Debentures in full on the scheduled maturity date or, if sufficient proceeds are not realized from the sale of such qualifying capital securities by such date, on each interest payment date thereafter. Any remaining outstanding principal will be due on June 15, 2067, the final maturity date.

The Progressive Corporation issued $400 million of 3.70% Senior Notes due 2045 in January 2015, and $350 million of 4.35% Senior Notes due 2044 in April 2014, in underwritten public offerings. We received proceeds, after deducting underwriter's discounts and commissions, of approximately $394.9 million and $346.3 million, respectively. In addition, we incurred expenses of approximately $0.8 million and $0.7 million, respectively, related to the issuances.

Prior to issuance of each of the Senior Notes and 6.70% Debentures, we entered into forecasted debt issuance hedges against possible rises in interest rates. Upon issuance of the applicable debt securities, the hedges were closed and we recognized unrealized gains (losses) as part of accumulated other comprehensive income. We recognize the gains and losses as an adjustment to interest expense and amortize them over the applicable life of the debt securities. The original unrealized gain (loss) at the time of each debt issuance and the unamortized balance at December 31, 2015, on a pretax basis, of these hedges, were as follows:



(millions)	Unrealized Gain (Loss) at Debt Issuance			Unamortized Balance at December 31, 2015
3.75% Senior Notes	$	(5.1	)	$	(3.1	)
6 5/8% Senior Notes	(4.2		)	(3.0		)
6.25% Senior Notes	5.1			3.9
4.35% Senior Notes	(1.6		)	(1.6		)
3.70% Senior Notes	(12.9		)	(12.6		)
6.70% Debentures	34.4			3.9

The gains (losses) on these hedges are deferred and are being amortized as adjustments to interest expense over the life of the related Senior Notes, and over the 10-year fixed interest rate term for the 6.70% Debentures. In addition to this amortization, during 2015 and 2014, we reclassified $0.2 million and $0.5 million, respectively, on a pretax basis, from accumulated other comprehensive income on the balance sheet to net realized gains on securities on the comprehensive income statement, reflecting the portion of the unrealized gain on forecasted transactions that was related to the portion of the 6.70% Debentures repurchased during the periods.

During 2015 and 2014, we repurchased, in the open market, $18.4 million and $44.3 million, respectively, in aggregate principal amount of the 6.70% Debentures. Since the amount paid exceeded the carrying value of the debt we repurchased, we recognized losses on these extinguishments of $0.9 million and $4.8 million, respectively.

ARX Debt (i.e., Other debt instruments)

The other debt instruments were issued by ARX, in which we acquired a controlling interest during the second quarter 2015. ARX, not The Progressive Corporation or any of its other subsidiaries, is responsible for the other debt, which includes amounts that were borrowed and contributed to the capital of ARX's insurance subsidiaries or used, or made available for use, for other business purposes.

In estimating the fair value of the other debt instruments, it was determined that the fair value of these notes is equal to the carrying value, based on the current rates offered for debt of similar maturities and interest rates.

The term loans require ARX and its subsidiaries to maintain specified debt leverage and fixed charge coverage ratios, as well as maintain a minimum risk-based capital ratio and minimum financial strength and credit ratings, as provided by A.M. Best Company, Inc. As of December 31, 2015, ARX was in compliance with these covenants. The surplus note requires ARX to maintain at least $50 million of surplus, which it met at December 31, 2015. There are no restrictive financial covenants or credit rating triggers on any of the remaining other debt instruments.

Monthly interest and principal payments are made on the term loans, with interest calculated based on the 30-day LIBOR plus 2.25%. Principal payments of $25.0 million are required to be paid during the next twelve months on these term loans. The term loans are secured by 100% of the outstanding common stock of four subsidiaries of ARX.

Interest on the junior subordinated notes and the senior notes is paid quarterly at a floating rate tied to the three-month LIBOR rate. Principal and interest on the surplus note is payable pursuant to a schedule permitted by the Florida Office of Insurance Regulation, and interest is set quarterly based upon the 10-year U.S. treasury bond rate. Principal payments of $2.2 million are due during the next twelve months on the surplus note.

The junior subordinated notes and senior notes can be redeemed, in whole or in part, at the option of ARX at par, plus accrued and unpaid interest, on any interest payment date.

Pursuant to agreements entered into by ARX relating to the trust preferred securities transactions, ARX established trusts that are 100% owned by ARX. The trusts, which are the holders of the junior subordinated notes, issued trust preferred securities to third parties. The shares in the trusts are not transferable. The trusts are considered special purpose variable interest entities for which ARX is not the primary beneficiary and, therefore, they are accounted for under the equity method of accounting and not consolidated with ARX. Our ownership interest of $1.3 million in the variable interest entities is reported as a component of "other assets" on our consolidated balance sheets.

The Progressive Corporation Line of Credit

In March 2015, we renewed the unsecured, discretionary line of credit (the "Line of Credit") with PNC Bank, National Association (PNC) in the maximum principal amount of $100 million. The prior line of credit, entered into in March 2014, has expired. The Line of Credit is on substantially the same terms and conditions as the prior line of credit. Subject to the terms and conditions of the Line of Credit documents, advances under the Line of Credit (if any) will bear interest at a variable rate equal to the higher of PNC's Prime Rate or the sum of the Federal Funds Open Rate plus 50 basis points. Each advance must be repaid on the 30th day after the advance or, if earlier, on April 30, 2016, the expiration date of the Line of Credit. Prepayments are permitted without penalty. All advances under the Line of Credit are subject to PNC's discretion. We had no borrowings under the Line of Credit or the prior line of credit in 2015 or 2014.
