Total debt, which includes long-term debt, current maturities of long-term debt, commercial paper and other short-term borrowings, was $4.7 billion, $6.6 billion and $6.8 billion for 2017, 2016 and 2015, respectively.

The total debt-to-capital ratio and the net debt-to-net capital ratio (less cash and short-term investments) decreased in 2017 due to lower total debt outstanding and higher common stockholders’ equity from changes in other comprehensive income.
The total debt-to-capital ratio and the net debt-to-net capital ratio (less cash and short-term investments) increased in 2016 due to lower common stockholders’ equity from share repurchases and changes in other comprehensive income.
The operating cash flow from continuing operations-to-debt ratio increased in 2017 primarily due to lower debt in the current year.
The operating cash flow from continuing operations-todebt ratio increased in 2016 primarily due to taxes paid in 2015 on the divestiture gains and lower debt in 2016.
The interest coverage ratio is computed as earnings from continuing operations before income taxes plus interest expense, divided by interest expense.
The increase in interest coverage in 2017 reflects lower interest expense in the current year.
The decrease in interest coverage in 2016 reflects lower pretax earnings, largely due to the divestiture gains of $1,039 million in 2015, and slightly higher interest expense.

Generally, the lower the debt service coverage ratio, the higher the risk of experiencing a credit loss.
For our commercial mortgage loans, our average loan-to-value ratio was 52% and 55% at December 31, 2014 and 2013, respectively, and our average debt service coverage ratio was 2.6x and 2.4x at December 31, 2014 and 2013, respectively.
The commercial mortgage loan debt service coverage ratio and loan-to-value ratio, as well as the values utilized in calculating these ratios, are updated annually, on a rolling basis, with a portion of the commercial mortgage loan portfolio updated each quarter.
For our agricultural mortgage loans, our average loan-to-value ratio was 44% and 45% at December 31, 2014 and 2013, respectively.
The values utilized in calculating the agricultural mortgage loan loan-to-value ratio are developed in connection with the ongoing review of the agricultural loan portfolio and are routinely updated.
Mortgage Loan Valuation Allowances.
Our valuation allowances are established both on a loan specific basis for those loans considered impaired where a property specific or market specific risk has been identified that could likely result in a future loss, as well as for pools of loans with similar risk characteristics where a property specific or market specific risk has not been identified, but for which we expect to incur a loss.
Accordingly, a valuation allowance is provided to absorb these estimated probable credit losses.
The determination of the amount of valuation allowances is based upon our periodic evaluation and assessment of known and inherent risks associated with our loan portfolios.
Such evaluations and assessments are based upon several factors, including our experience for loan losses, defaults and loss severity, and loss expectations for loans with similar risk characteristics.
These evaluations and assessments are revised as conditions change and new information becomes available, which can cause the valuation allowances to increase or decrease over time as such evaluations are revised.
Negative credit migration, including an actual or expected increase in the level of problem loans, will result in an increase in the valuation allowance.
Positive credit migration, including an actual or expected decrease in the level of problem loans, will result in a decrease in the valuation allowance.
See Notes 1, 8 and 10 of the Notes to the Consolidated Financial Statements for information about how valuation allowances are established and monitored, activity in and balances of the valuation allowance, and the estimated fair value of impaired mortgage loans and related impairments included within net investment gains (losses) as of and for the years ended December 31, 2014, 2013 and 2012.
Real Estate and Real Estate Joint Ventures We diversify our real estate investments by both geographic region and property type to reduce risk of concentration.

The carrying value of our real estate investments located in California, Japan and Florida were 19%, 13% and 9%, respectively, of total real estate investments at December 31, 2014.

## Table 2 ##
We classify within traditional real estate our investment in income-producing real estate, which is comprised primarily of wholly-owned real estate and, to a much lesser extent, joint ventures with interests in single property income-producing real estate.
The estimated fair value of the traditional and held-for-sale real estate investment portfolios was $13.3 billion and $12.5 billion at December 31, 2014 and 2013, respectively.
We classify within real estate joint ventures and funds, our investments in joint ventures with interests in multi-property projects with varying strategies ranging from the development of properties to the operation of income-producing properties, as well as our investments in real estate private equity funds.
From time to time, we transfer investments from these joint ventures to traditional real estate after the completed property commences operations and, if we intend to retain an interest in the property.
In connection with our investment management business, in the fourth quarter of 2013, we contributed real estate investments with an estimated fair value of $1.4 billion to the MetLife Core Property Fund, our newly formed open ended core real estate fund, in return for the issuance of ownership interests in that fund.
As part of the initial closing on December 31, 2013, we redeemed 76% of our interest in this fund as new third party investors were admitted.
The MetLife Core Property Fund was consolidated as of December 31, 2013.
However, as a result of our quarterly reassessment in the first quarter of 2014, we no longer consolidate the MetLife Core Property Fund, effective March 31, 2014.

Table of Contents 136 Current Environment As a global insurance company, we continue to be impacted by the changing global financial and economic environment, as well as the monetary policy of central banks around the world.
See “— Industry Trends — Financial and Economic Environment.
