(1)	The 1.625% Notes have a contractual maturity date in 2044; however, on specified dates beginning in 2018 as described below, holders of the 1.625% Notes may require us to repurchase some or all of the 1.625% Notes, or we may redeem any or all of the 1.625% Notes.

1.125% Cash Convertible Senior Notes due 2020. In February 2013, we issued $550.0 million aggregate principal amount of 1.125% cash convertible senior notes (the 1.125% Notes) due January 15, 2020, unless earlier repurchased or converted. Interest on the 1.125% Notes is payable semiannually in arrears on January 15 and July 15 at a rate of 1.125% per annum.

The 1.125% Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the 1.125% Notes; equal in right of payment to any of our unsecured indebtedness that is not subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities of our subsidiaries.

The 1.125% Notes are convertible only into cash, and not into shares of our common stock or any other securities. The initial conversion rate for the 1.125% Notes is 24.5277 shares of our common stock per $1,000 principal amount of the 1.125% Notes. This represents an initial conversion price of approximately $40.77 per share of our common stock. The conversion rate is subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Holders may convert their 1.125% Notes only under the following circumstances:

•

during any calendar quarter commencing after the calendar quarter ending on June 30, 2013 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;


•	during the five business day period immediately after any five consecutive trading day period (the measurement period) in which the trading price per $1,000 principal amount of 1.125% Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day;


•	upon the occurrence of specified corporate events; or

•

at any time on or after July 15, 2019 until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, in lieu of receiving shares of our common stock, a holder will receive an amount in cash, per $1,000 principal amount of 1.125% Notes, equal to the settlement amount, determined in the manner set forth in the indenture. We may not redeem the 1.125% Notes prior to the maturity date.

As of December 31, 2014, the 1.125% Notes were not convertible.

The 1.125% Notes contain an embedded cash conversion option (the 1.125% Notes Conversion Option), which was separated from the 1.125% Notes and accounted for separately as a derivative liability, with changes in fair value reported in our consolidated statements of income until the 1.125% Notes Conversion Option transaction settles or expires. The initial fair value liability of the 1.125% Notes Conversion Option simultaneously reduced the carrying value of the 1.125% Notes (effectively an original issuance discount). This discount is amortized to the 1.125% Notes' principal amount through the recognition of non-cash interest expense over the expected life of the debt. This has resulted in our recognition of interest expense on the 1.125% Notes at an effective rate approximating what we would have incurred had nonconvertible debt with otherwise similar terms been issued, or approximately 6%. As of December 31, 2014, we expect the 1.125% Notes to be outstanding until their maturity date, for a remaining amortization period of 5.0 years. The 1.125% Notes' if-converted value exceeded their principal amount by approximately $93 million as of December 31, 2014, and did not exceed their principal amount as of December 31, 2013.

3.75% Exchange. In August 2014, we entered into separate, privately negotiated, exchange agreements (the 3.75% Exchange) with certain holders of our outstanding 3.75% convertible senior notes due 2014 (the 3.75% Notes). In this transaction, we exchanged $176.6 million aggregate principal amount of the 3.75% Notes for $176.6 million principal amount of 1.625% convertible senior notes due 2044 (see further discussion below), approximately 1.7 million shares of our common stock, and payment of accrued interest on the exchanged 3.75% Notes. We did not receive any proceeds related to the 3.75% Exchange.

1.625% Convertible Senior Notes due 2044. In September 2014, we issued $125.0 million principal amount of 1.625% convertible senior notes (the 1.625% Notes) due August 15, 2044, unless earlier repurchased, redeemed or converted. Combined with the 1.625% Notes issued in connection with the 3.75% Exchange described above, the aggregate principal amount issued under the 1.625% Notes was $301.6 million.

Interest on the 1.625% Notes is payable semiannually in arrears on February 15 and August 15, at a rate of 1.625% per annum, beginning on February 15, 2015. In addition, beginning with the semiannual interest period commencing immediately following the interest payment date on August 15, 2018, contingent interest will accrue on the 1.625% Notes during any semiannual interest period in which certain conditions or events occur, or under certain events of default. For example, additional interest of 0.25% per year will be payable on the 1.625% Notes for any semiannual interest period for which the principal amount of 1.625% Notes outstanding is less than $100 million.

The proceeds from the issuance of the 1.625% Notes amounted to $122.6 million, including a premium of $0.6 million, and net of deferred issuance costs paid for both the 3.75% Exchange and the additional $125.0 million principal amount issued. In connection with aggregate principal amount of the 1.625% Notes, we have recorded total deferred issuance costs of approximately $6 million, which will be amortized over the expected term of the debt, as discussed further below.

The 1.625% Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the 1.625% Notes; equal in right of payment to any of our unsecured indebtedness that is not subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities of our subsidiaries.

The initial conversion rate for the 1.625% Notes is 17.2157 shares of our common stock per $1,000 principal amount of the 1.625% Notes. This represents an initial conversion price of approximately $58.09 per share of our common stock. Upon conversion, we will pay cash and, if applicable, deliver shares of our common stock to the converting holder in an amount per $1,000 principal amount of 1.625% Notes equal to the settlement amount (as defined in the related indenture). Holders may convert their 1.625% Notes only under the following circumstances:

•

during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;


•	during the five business day period after any five consecutive trading day period (the measurement period) in which the trading price per $1,000 principal amount of 1.625% Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day;


•	upon the occurrence of specified corporate events;


•	if we call any 1.625% Notes for redemption, at any time until the close of business on the business day immediately preceding the redemption date;


•	during the period from, and including, May 15, 2018 to the close of business on the business day immediately preceding August 19, 2018; or


•	at any time on or after February 15, 2044 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 1.625% Notes, in integral multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.

As of December 31, 2014, the 1.625% Notes were not convertible.

We may not redeem the 1.625% Notes prior to August 19, 2018. On or after August 19, 2018, we may redeem for cash all or part of the 1.625% Notes, except for the 1.625% Notes we are required to repurchase in connection with a fundamental change or on any specified repurchase date. The redemption price for the 1.625% Notes will equal 100% of the principal amount of the 1.625% Notes being redeemed, plus accrued and unpaid interest. In addition, holders of the 1.625% Notes may require us to repurchase some or all of the 1.625% Notes for cash on August 19, 2018, August 19, 2024, August 19, 2029, August 19, 2034 and August 19, 2039, in each case, at a specified price equal to 100% of the principal amount of the 1.625% Notes to be repurchased, plus accrued and unpaid interest.

Because the 1.625% Notes have cash settlement features, we have allocated the principal amount between a liability component and an equity component. The reduced carrying value on the 1.625% Notes resulted in a debt discount that is amortized back to the 1.625% Notes' principal amount through the recognition of non-cash interest expense over the expected life of the debt. The expected life of the debt is approximately four years, beginning on the issuance date and ending on the first date we may redeem the notes in August 2018. As of December 31, 2014, we expect the 1.625% Notes to be outstanding until August 2018, for a remaining amortization period of 3.6 years. This has resulted in our recognition of interest expense on the 1.625% Notes at an effective rate approximating what we would have incurred had nonconvertible debt with otherwise similar terms been issued, or approximately 5%. The outstanding 1.625% Notes’ if-converted value did not exceed their principal amount as of December 31, 2014. At December 31, 2014, the equity component of the 1.625% Notes, including the impact of deferred taxes, was $22.9 million.

3.75% Convertible Senior Notes due 2014. As described above, we entered into the 3.75% Exchange transaction in August 2014, under which we exchanged $176.6 million of the outstanding principal amount of the 3.75% Notes for the 1.625% Notes. The remaining $10.4 million principle amount was repaid in full in October 2014. In addition to the repayment of the outstanding principle balance, in early October 2014 we issued approximately 0.1 million shares to settle the 3.75% Notes' conversion feature.

The principal amounts, unamortized discount (net of premium related to 1.625% Notes), and net carrying amounts of the convertible senior notes were as follows:

Lease Financing Obligations. In 2013 we entered into a sale-leaseback transaction for the sale and contemporaneous leaseback of the Molina Center located in Long Beach, California, and our Ohio health plan office building located in Columbus, Ohio. Due to our continuing involvement with these leased properties, the sale did not qualify for sale-leaseback accounting treatment and we remain the "accounting owner" of the properties. These assets continue to be included in our consolidated balance sheets, and also continue to be depreciated and amortized over their remaining useful lives. The lease financing obligation is amortized over the 25-year lease term such that there will be no gain or loss recorded if the lease is not extended at the end of its term. Rent will increase 3% per year through the initial term. Payments under the lease adjust the lease financing obligation, and the imputed interest is recorded to interest expense in our consolidated statements of income. Such interest amounted to $12.5 million and $6.8 million for the year ended December 31, 2014 and 2013, respectively.

As described and defined in further detail in Note 18, "Related Party Transactions," we entered into a lease for office space in February 2013 consisting of two office buildings. We have concluded that we are the accounting owner of the buildings due to our continuing involvement with the properties. We have recorded $38.4 million to property, equipment and capitalized software, net, in the accompanying consolidated balance sheet as of December 31, 2014, which represents the total cost incurred by the Landlord for the construction of the buildings, net of accumulated depreciation. As of December 31, 2014, the aggregate amount recorded to lease financing obligations, including the current portion, amounted to $40.6 million. Payments under the lease adjust the lease financing obligation, and the imputed interest is recorded to interest expense in our consolidated statements of income. Such interest expense for the years ended December 31, 2014, and 2013, was $3.2 million and $1.3 million, respectively. In addition to the capitalization of the costs incurred by the Landlord, we impute and record rent expense relating to the ground leases for the property sites. Such rent expense is computed based on the fair value of the land and our incremental borrowing rate, amounting to $1.1 million for the year ended December 31, 2014, and insignificant for the year ended December 31, 2013. For information regarding the future minimum lease obligation, refer to Note 20, "Commitments and Contingencies."
