Trends and Recent Market Impacts

Global equity and bond markets finished fiscal year 2019 on a positive note, as signs of stabilization in global economic growth and prospects of a “Phase 1” trade deal between the U.S.

and China emerged.

Notwithstanding the strong end to 2019, concerns over slower growth and trade tensions contributed to periods of pronounced interest rate volatility during the year, with the 10-year U.S.

Treasury note rate declining from 2.68% at the start of the year to a multi-year low of 1.42%, before closing the year at 1.92%.

Many major central banks responded to the growing global growth concerns by lowering short-term rates as well as implementing other forms of monetary policy accommodation during the year.

For its part, the U.S.

Federal Reserve pivoted sharply from its campaign of raising short-term interest rates at the end of 2018 and, for the first time since 2008, lowered the federal funds target rate by 25 basis point rate cuts at each of its July, September, and October 2019 meetings.

In August 2019, the Fed also suspended the runoff of its U.S.

Treasury portfolio and began redeploying up to $20 billion per month of paydowns from its Agency RMBS portfolio into Treasury securities and reinvesting paydowns in excess of $20 billion into Agency RMBS, maintaining a larger balance sheet than the market had previously anticipated.

Notwithstanding the Fed’s more accommodative stance, repo rates remained elevated throughout the year compared to other short-term rates, and, in September, disruptions in the repo market led to a large spike in overnight rates.

In response, the Fed reinstituted daily open market repurchase operations at the end of the third quarter, thereby adding significant liquidity to the repo market.

In October, the Fed announced additional measures to further stabilize the funding markets through monthly purchases of Treasury bills and an increase to its overnight and term open market operations.

Together, these actions added in excess of $400 billion of liquidity to the system as of the end of 2019.

The Fed also announced that it would continue its monthly U.S.

Treasury purchase program and its open market repurchase operations through the first half of 2020.

Although specific future Fed actions, including continuation of these or other additional efforts, are uncertain, its actions added stability to the overnight repo markets at the end of December 2019, and, as such, we expect repo funding will return to more normal levels relative to the federal funds rate in 2020.

equities and other risk assets performed well during the year, reaching new highs as greater central bank accommodation outweighed concerns over global economic weakness.

The performance of Agency RMBS, however, was mixed.

During the first quarter, Agency RMBS outperformed U.S.

Treasury and interest rate swap hedges but underperformed in the second and third quarters due to elevated prepayment concerns and a flattening yield curve.

Late in the fourth quarter, the combination of easing trade tensions, increasing monetary accommodation and diminished prepayment concerns resulting from rising interest rates drove mortgage spreads meaningfully tighter and reversed much of the spread widening from the prior two quarters.

Despite these challenging conditions, our tangible economic return for the year was 18.7%, consisting of a $1.10 increase in tangible net book value per common share and $2.00 of dividends per common for the year.

Asset selection and hedge repositioning drove much of our strong performance for the year.

Prepayment risk in the Agency RMBS market increased significantly over the course of the year as interest rates fell.

A large percentage of our portfolio, however, consisted of specified Agency RMBS with favorable attributes that reduce the likelihood of prepayment.

As a result, these assets meaningfully outperformed other more generic Agency RMBS.

In addition, we proactively reduced our holdings of higher coupon, generic Agency RMBS in favor of lower coupon RMBS, which significantly reduced our exposure to faster prepayments while also taking advantage of compelling valuations.

On the hedge side, we increased our interest rate hedges from 77% of our aggregate funding liabilities as of the start of the year to 102% at year-end.

We also adjusted the duration and composition of our hedge portfolio, taking advantage of material repricing events in the interest rate swap market during the year.

As a result, despite significant interest rate volatility, our duration gap, which is a measure of the mismatch between the interest sensitivity of our assets and liabilities, inclusive of interest rate hedges, remained relatively stable during year and was 0.4 years as of December 31, 2019, compared to 0.2 years as of December 31, 2018.

(For additional information regarding our interest rate and spread sensitivity please refer to Item 3.

Quantitative and Qualitative Disclosures about Market Risk of this Form 10-K.)

Our net spread and dollar roll income (a non-GAAP measure) was $1.97 per common share for the year, compared to $2.40 per common share for 2018.

Excluding "catch-up" premium amortization, net spread and dollar roll income was $2.16 per common share for the year, a decline from $2.35 per common share for 2018 largely due to higher funding costs resulting from multiple Fed rate hikes in prior years and persistently elevated repo funding costs during 2019.

Our net interest spread, which represents the difference in the yield on our assets (excluding “catch-up” amortization and including TBA securities) and our cost of funds, was 1.18% for 2019, compared to 1.27% for 2018.

(For additional information regarding non-GAAP measures and reconciliations to the the most comparable GAAP measure please refer to Results of Operations later within this MD&A.)

Our average forecasted portfolio CPR as of December 31, 2019 was 10.8% , an increase from 7.9% , consistent with the decline in longer-term rates.

Our actual portfolio CPR averaged 11.4% for the year, an increase from 8.7% for 2018 but well below prepayment rates observed on other generic, higher coupon Agency RMBS.

Our tangible net book value "at risk" leverage increased to 9.4x as of December 31, 2019, from 9.0x as of December 31, 2018, and averaged 9.7x for the year, compared to 8.3x for 2018, as Agency RMBS valuations relative to interest rate hedges during the year enhanced our expected risk-adjusted returns.

In March 2020, the COVID-19 pandemic triggered one of the most severe and sudden financial market downturns in U.S.

As the U.S and the world grappled with the rapidly deteriorating public health situation late in the first quarter, financial markets experienced historically rapid and severe liquidity shortfalls and declined precipitously.

The Fed and the U.S.

Treasury, together with their global counterparts, took decisive actions to allay the global financial crisis in late March and early April, which stabilized the financial markets and ultimately drove a recovery throughout the remainder of the year.

In the U.S., the Fed's unprecedented monetary accommodation, which included substantial outright purchases of U.S.

Treasury and Agency RMBS securities and a near-zero interest rate policy, and a massive fiscal stimulus package drove a rebound across substantially all asset categories.

By year-end, U.S.

Treasury and Agency RMBS markets had fully stabilized, equity markets had rebounded to new highs, and credit spreads had tightened to pre-COVID levels as a result of the ongoing monetary and fiscal stimulus and optimism regarding vaccine efficacy, the combination of which boosted prospects for a broad-based economic recovery that is expected to gain significant momentum in the latter half of 2021.

In response to the Pandemic and resulting market disruptions and volatility, we took early action to strengthen our liquidity position and mitigate risk across our portfolio.

We repositioned the portfolio and increased more efficient funding sourced from our captive broker-dealer subsidiary, benefiting AGNC’s overall liquidity position and, in turn, avoiding the need to make significant portfolio sales at distressed levels to meet margin calls.

As a result, after experiencing a significant book

value decline in the first quarter of 2020, resulting in an economic loss for the quarter of -20.2%, AGNC posted three straight quarters of substantial economic returns:

12.2%, 8.8%, and 7.5%, respectively.

This strong performance drove a full year 2020 economic return of 3.5%, comprised of $1.56 in cash dividends per common share and a ($0.95) per share decline in tangible net book value per common share.

Considering the extraordinarily difficult market conditions in the first quarter, these results demonstrate the importance and value of AGNC's disciplined investment framework and risk management practices.

Moreover, the experience of 2020 clearly illustrates the unique value of a predominately Agency RMBS portfolio.

In times of significant market stress, the Fed has repeatedly shown a commitment to supporting and stabilizing the U.S.

housing finance system because of the significant impact this market has on the broader social and economic well-being of the country.

2020 was no exception, as the Fed purchased $1.5 trillion of Agency RMBS during the year and held approximately 30% of all outstanding Agency RMBS at year end.

Our portfolio management throughout the year, coupled with the Fed's continued support of the RMBS market, ultimately facilitated AGNC's recovery of substantially all of the tangible net book value decline experienced in the first quarter.

Importantly, the Fed has signaled that it intends to maintain its accommodative monetary policy stance until its objectives of maximum employment and long-term average inflation targets are achieved and that it expects to continue to increase its holdings of U.S.

Treasury securities and Agency RMBS until substantial further progress has been made toward achieving these goals.

The Fed's actions and strong demand for Agency RMBS drove primary mortgage rates to historic lows during the year and triggered the largest mortgage refinance wave in almost 20 years.

To manage the risk of increased prepayments on our portfolio, we shifted the composition of our portfolio to include a greater share to lower coupon 30 and 15-year TBA securities, while maintaining our higher coupon holdings concentrated in high quality, specified Agency RMBS pools.

In this elevated prepayment environment, our higher coupon specified pools performed considerably better than more generic RMBS, while our lower coupon holdings benefited from the extremely favorable funding conditions in the TBA dollar roll market, a result of significant new Agency RMBS issuance and the Fed's high level of participation.

As of December 31, 2020, our investment portfolio totaled $97.9 billion, consisting of $65.1 billion Agency RMBS, $31.5 billion TBA securities, and $1.3 billion of CRT and non-Agency securities.

Our "at risk" leverage, as of December 31, 2020, was 8.5x our tangible equity, and our liquidity position, consisting of unencumbered Agency RMBS and cash, was $5.4 billion, which excludes unencumbered credit assets and assets held at our broker-dealer subsidiary.

The average prepayment rate on our Agency RMBS holdings during the year peaked at an annualized rate of 27.6% for the fourth quarter, significantly below speeds for similar coupon generic securities.

As of December 31, 2020, our Agency RMBS had an average remaining life CPR forecast of 17.6%.

Our interest rate exposure remained limited throughout the year despite significant movements in interest rates as we actively managed the size and composition of our interest rate hedge position in response to changing market conditions.

In the fourth quarter, we increased our interest rate hedge ratio to 80% of our funding liabilities (compared to our intra-year low of 66% at the end of the second quarter) as the macroeconomic outlook became more favorable and the risk of higher longer term interest rates increased.

Our duration gap, which is a measure of the difference between the interest rate sensitivity of our assets and liabilities, inclusive of our interest rate hedges, was -0.5 years as of December 31, 2020, consistent with the reduction of our asset durations and our bias in the current environment to operate with incrementally more up-rate protection.

The funding environment for Agency RMBS remained favorable throughout the year.

The Agency MBS repo market remained highly liquid and functioned normally, even during the broad financial market turmoil experienced in March.

Our average funding cost moved steadily lower over the course of the year as the Fed acted quickly to reduce the Fed Funds rate to the zero bound range early in the crisis.

As of December 31, 2020, our average repo rate was 0.24%, down substantially from 2.17 % at the start of the year.

These favorable repo rates, even lower implied financing rates in the TBA dollar roll market, and reduced interest rate swap costs collectively drove a substantial improvement in our aggregate cost of funds, which declined to 0.05% in the fourth quarter from 1.67% in the first quarter.

This very favorable funding dynamic more than offset the decline in asset yields on our portfolio and drove a significant improvement in our net interest spread.

As a result of our materially higher net interest spread, net spread and dollar roll income (a non-GAAP measure) totaled $2.70 per common share, excluding "catch-up" amortization cost, for the year.

(Refer to Results of Operations below for further information regarding non-GAAP measures.)

Looking ahead, valuations of all financial assets have become elevated and, in many cases, are now above pre-COVID levels.

With Agency RMBS valuations similarly elevated, the expected return profile on new investments has correspondingly declined.

As a result, the net interest spread on our investment portfolio is likely to compress moderately as asset cash flows are reinvested at lower prevailing asset yields and the implied funding advantage of TBAs reverts to more historical norms.

Nevertheless, we believe Agency RMBS remain attractive on a relative basis for levered investors given the dual benefits of low funding costs and the likelihood of ongoing Fed purchases.

We believe that the near zero short-term interest rate environment is likely to remain in place through at least 2023, the Fed is unlikely to begin tapering its Agency RMBS purchases before 2022, and any such tapering will likely be gradual over a multi-month period.

Although any decisions by the Fed to taper

its investments in Agency RMBS could occur earlier or later than our current expectation, the Fed has indicated that it will seek to communicate its intentions well in advance of taking any such action so as to reduce market uncertainty.

Importantly, even after the Fed completes the taper process, it has indicated an intention to continue to reinvest portfolio paydowns for an extended period of time, likely until it begins to raise the Federal Funds target.

Nonetheless, we may experience periods of increased volatility as markets begin to price in an eventual shift in the Fed's monetary policy.

In the current environment with asset valuations elevated, we may choose to operate at comparatively lower leverage for periods of time to mitigate the potential downside risk to our tangible net book value associated with a reduced Fed presence, as well as to afford us the ability to increase leverage opportunistically when expected return levels are more favorable.

That said, the recent increase in longer term interest rates, if it continues, should ultimately lead to a more benign prepayment environment for mortgage assets.

Although Agency RMBS valuations have increased along with the vast majority of financial assets over the past several quarters, we believe significant ongoing Fed purchases, potentially slower prepayments, and attractive funding levels should continue to be positive factors for AGNC.

________________________________

The average implied asset yield for TBA dollar roll transactions is extrapolated by adding the average TBA implied funding cost (benefit) (Note 3) to the net dollar roll yield.

The net dollar roll yield is calculated by dividing dollar roll income by the average net TBA balance (cost basis) outstanding for the period.

Dollar roll income represents the price differential, or "price drop," between the TBA price for current month settlement versus the TBA price for forward month settlement.

Amount includes dollar roll income (loss) on long and short TBA securities.

Amount excludes TBA mark-to-market adjustments.

Amount calculated on a weighted average basis based on average balances outstanding during the period and their respective asset yield/funding cost.

The implied funding cost/(benefit) of TBA dollar roll transactions is determined using the "price drop" and market based assumptions regarding the "cheapest-to-deliver" collateral that can be delivered to satisfy the TBA contract, such as the anticipated collateral’s weighted average coupon, weighted average maturity and projected 1-month CPR.

The average implied funding cost/benefit for all TBA transactions is weighted based on the daily average TBA balance outstanding for the period.

Represents interest rate swap periodic cost/(income) measured as a percent of total mortgage funding (Agency repurchase agreements, other debt and net TBA securities).

Amount excludes interest rate swap termination fees and mark-to-market adjustments.

Cost of funds excludes other supplemental hedges used to hedge a portion of the Company's interest rate risk (such as swaptions and U.S.

Treasury positions) and U.S.

Treasury repurchase agreements.

Interest Income

The effective yield on our Agency RMBS and non-Agency securities of high credit quality is highly impacted by our estimate of future prepayments.

We accrue interest income based on the outstanding principal amount and their contractual terms and we amortize or accrete premiums and discounts associated with our purchase of these securities into interest income over their projected lives, taking into account scheduled contractual payments and estimated prepayments, using the interest method.

We accrue interest income based on the outstanding principal amount and contractual terms of these securities, and we amortize or accrete premiums and discounts associated with our purchase of these securities into interest income over their projected lives, taking into account scheduled contractual payments and estimated prepayments, using the interest method.

The weighted average cost basis of our securities as of December 31, 2020 was 104.0% of par value;

therefore, faster actual or projected prepayments could significantly reduce the yield on our assets.

therefore, faster actual or projected prepayments than our estimates could significantly reduce the yield on our assets.

Future prepayment rates are difficult to predict, and we rely on a third-party service provider and our experience and analysis of historical and current market data to arrive at what we believe to be reasonable estimates.

Our third-party service provider estimates prepayment speeds using models that incorporate the forward yield curve, current mortgage rates, mortgage rates on the outstanding loans, age and size of the outstanding loans, loan-to-value ratios, interest rate volatility and other factors.

"Economic interest expense" is measured as interest expense (GAAP measure) adjusted to include TBA dollar roll implied interest expense and interest rate swap periodic income/(cost).

"Net spread and dollar roll income, excluding "catch-up" premium amortization" includes (i) the components of economic interest income and economic interest expense and other interest and dividend income (referred to as "adjusted net interest and dollar roll income"), less (ii) total operating expenses (GAAP measure), net of management

fee income (GAAP measure), adjusted, as applicable, to exclude one-time expenses and termination fee income recognized in connection with MTGE's termination of its management agreement due to the sale of MTGE to a third-party.

"Economic interest expense" is measured as interest expense (GAAP measure) adjusted to include TBA dollar roll implied interest expense/(benefit) and interest rate swap periodic cost/(income).

By providing such measures, in addition to the related GAAP measures, we believe we give greater transparency into the information used by our management in its financial and operational decision-making.

In the case of "economic interest income" and "net spread and dollar roll income, excluding 'catch-up' premium amortization," we believe the exclusion of "catch-up" adjustments to premium amortization cost or benefit is meaningful as it excludes the cumulative effect from prior reporting periods due to current changes in future prepayment expectations and, therefore, exclusion of such cost or benefit is more indicative of the current earnings potential of our investment portfolio.

In the case of estimated taxable income, we believe it is meaningful information because it directly relates to the amount of dividends we are required to distribute to maintain our REIT qualification status.

In the case of estimated taxable income, we believe it is meaningful information because it directly relates to the amount of dividends that we are required to distribute to maintain our REIT qualification status.

Our average investment portfolio, inclusive of TBAs, increased 30% and 22% (at cost) for fiscal years 2019 and 2018 , respectively, compared to the corresponding prior year period, largely as a function of deploying net proceeds from equity capital raises into incremental assets and increases to our tangible net book value "at risk" leverage ratio.

The annual increases in our average asset yield, excluding "catch-up" amortization and including TBAs, over the corresponding prior year period was largely due to changes in asset composition.

During each of 2019 and 2018, we increased our holdings of 30-year fixed rate securities relative to lower coupon, 15-year fixed rate securities.

During 2019, the increase in our average portfolio coupon was partly offset by an increase in premium amortization expense associated with lower long-term interest rates and correspondingly faster CPR projections;

whereas, during 2018, asset yields benefited from higher rates and correspondingly lower CPR projections, compared to the prior year period.

Our average investment portfolio, inclusive of TBAs (at cost), decreased 8% for fiscal year 2020 and increased 30% for fiscal year 2019, compared to the prior year periods, largely due to shifts in our targeted operating leverage and changes to our

total stockholders equity outstanding as a result of new equity issuances, a preferred stock redemption and common stock repurchases.

(See Note 9 of our Consolidated Financial Statements in this Form 10-K for additional information regarding our equity capital markets transactions).

The decrease in our average investment portfolio for fiscal year 2020 was in particular impacted by the decline in our tangible net stockholders' equity in the first quarter due to the COVID-19 financial crisis and our decision to operate with somewhat lower leverage for the balance of the year as compared to 2019.

The decrease in our average asset yield for fiscal year 2020 was due to changes in asset composition and faster actual and projected CPRs resulting from historically low mortgage rates resulting from the Fed's unprecedented monetary stimulus measures.

The moderate increase in our asset yield during 2019 was due to changes in asset composition and somewhat slower CPR projections.

Our primary measure of leverage is our tangible net book value "at risk" leverage ratio, which is measured as the sum of our repurchase agreements and other debt used to fund our investment securities and net TBA position (at cost) (together referred to as "mortgage borrowings") and our net receivable/payable for unsettled investment securities, divided by our total stockholders' equity adjusted to exclude goodwill and other intangible assets.

Our average mortgage borrowings, inclusive of TBAs, increased by 36% and 20% for fiscal years 2019 and 2018, respectively, compared to the corresponding prior year period as a function of our higher asset base.

The annual increases in the average interest rate (actual and implied) on our mortgage borrowings was largely due to increases in the federal funds rate during fiscal years 2018 and 2017.

The annual increases in our interest rate swap periodic interest income was due the combination of increases in our average swap position and increases in the net rate received on our interest rate swaps.

Our average mortgage borrowings, inclusive of TBAs, decreased 5% and increased 36% for fiscal years 2020 and 2019, respectively, largely due to shifts in our targeted operating leverage and changes to our total stockholders equity outstanding due to equity capital markets transactions.

The decline in our average interest rate (actual and implied) on our mortgage borrowings during fiscal year 2020 was largely due to a decline in the Fed Funds target rate to the zero bound range early in the COVID-19 financial crisis, compared to moderate increases in the Fed Funds rate in the prior two year periods.

TBA implied funding rates particularly benefited from a significant volume of new Agency RMBS issuance and the Fed's purchases of Agency RMBS through the TBA market.

Additionally, during fiscal year 2020, we terminated $3.7 billion of longer-dated repurchase agreements and replaced them with shorter duration repurchase agreements at lower prevailing market rates.

We recognized losses on debt extinguishment totaling $146 million in other gain (loss) during the period associated with the terminated agreements, which is excluded from economic interest expense in the tables above.

We did not terminate any repurchase agreements during fiscal years 2019 or 2018.

The increase in our interest rate swap periodic cost for fiscal year 2020 was largely due to a decline in the average floating rate received, consistent with lower short-term interest rates, which was partly offset by a decline in the average fixed rate paid on our interest rate swaps and a decline in our average swap balance outstanding.

The decrease in our interest rate swap cost during fiscal year 2019, was largely due to the combination of an increase in the average floating rate received and a decrease in the average fixed-rate paid on our interest rate swaps.

During fiscal years 2020 and 2019, we also adjusted the duration and

composition of our interest rates swaps, taking advantage of favorable repricing events in the interest rate swap markets, benefiting our interest rate swap cost.

Management Fee Income

Management fee income for fiscal years 2018 and 2017 consisted of $54 million and $38 million, respectively, of fees received from MTGE Investment Corp for asset management services.

Fees for fiscal year 2018 included $42 million of termination fee income from MTGE due to MTGE's termination of its management agreement as a result of its sale to a third party.

Operating Expenses

Operating expenses, for fiscal year 2019, were $83 million, compared to $100 million for fiscal year 2018.

The year-over-year decline in operating expenses was due to one-time expenses recognized during 2018 associated with the termination of MTGE's management, including the write-off or our intangible asset associated with the management agreement of $23 million and $4 million of other expenses.

Excluding these one-time items, our operating expenses increased by $10 million for fiscal year 2019, due to the combination of higher compensation costs and other general expenses.

Operating expenses for fiscal year 2018, excluding one-time items, were largely unchanged from fiscal year 2017.

Gain (Loss) on Investment Securities, Net

For the fiscal year 2019 , we had net gains on our investment securities of $3.4 billion resulting from the decline in long-term interest rates and an increase in the premium, or pay-up values, for our specified Agency RMBS holdings, given their lower likelihood of prepayment in low interest rate environments compared to generic Agency securities.

Conversely, during fiscal years 2018 and 2017, we incurred net losses of $1.0 billion and $0.1 billion, respectively, on our investment securities largely as a function of higher interest rates and declining pay-up values.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of funds are borrowings under master repurchase agreements, asset sales, receipts of monthly principal and interest payments on our investment portfolio and equity offerings.

We may also enter into TBA contracts to acquire or dispose of Agency RMBS and TBA dollar roll transactions to finance Agency RMBS purchases.

Because the level of our borrowings can be adjusted daily, the level of cash and cash equivalents carried on our balance sheet is significantly less important than the potential liquidity available under our borrowing arrangements.

Our leverage will vary periodically depending on market conditions and our assessment of risks and returns.

We generally would expect our leverage to be within six to twelve times the amount of our tangible stockholders' equity.

However, under certain market conditions, we may operate at leverage levels outside of this range for extended periods of time.

We currently believe that we have sufficient liquidity and capital resources available for the acquisition of additional investments, repayments on borrowings, maintenance of any margin requirements and the payment of cash dividends as required for our continued qualification as a REIT.

We expect to distribute 100% of our taxable income so that we are not subject to U.S.

federal and state corporate income taxes.

Our REIT distribution requirement of at least 90% of our taxable income limits our ability to retain earnings and thereby replenish or increase capital from operations.

As of December 31, 2019 and 2018 , our mortgage borrowings consisted of the following (dollars in millions):

Mortgage Borrowings

Our business is dependent on our ability to maintain adequate levels of liquidity and capital resources to fund day-to-day operations, fulfill collateral requirements under our funding and derivative agreements, and to satisfy our dividend distribution requirement of at least 90% of our taxable income to maintain our qualification as a REIT.

Our primary sources of liquidity are unencumbered cash and securities, borrowings available under repurchase agreements, TBA dollar roll financing and monthly receipts of principal and interest payments.

We may also conduct asset sales, change our asset or funding mix, issue equity or undertake other capital enhancing actions to maintain adequate levels of liquidity and capital resources.

We believe that we have sufficient liquidity and capital resources available to meet our obligations and execute our business strategy.

In assessing our liquidity, we consider a number of factors, including our current leverage, collateral levels, access to capital markets, overall market conditions, and the sensitivity of our tangible net book value over a range of scenarios.

However, these and other factors impacting our liquidity are subject to numerous risks and uncertainties, including as described in the Quantitative and Qualitative Disclosures of Market Risks and Risk Factors sections of this Form 10-K.

Leverage and Financing Sources

Our leverage will vary depending on market conditions and our assessment of relative risks and returns, but we generally expect our leverage to be between six and twelve times the amount of our tangible stockholders' equity, measured as the sum of our total mortgage borrowings and net payable / (receivable) for unsettled investment securities, divided by the sum of our total stockholders' equity adjusted to exclude goodwill.

Our tangible net book value "at risk" leverage ratio was 8.5x and 9.4x as of December 31, 2020 and 2019, respectively.

The following table includes a summary of our mortgage borrowings outstanding as of December 31, 2020 and 2019 (dollars in millions).

Repurchase Agreements

As part of our investment strategy, we borrow against our investment portfolio pursuant to master repurchase agreements.

We expect that the majority of our borrowings under repurchase agreements will have maturities ranging up to one year but may have terms ranging up to five years or longer.

Borrowings with maturities greater than one year may have floating rates of interest based on a short-term benchmark rate plus or minus a fixed spread.

As of December 31, 2019 , we had $89.1 billion of repurchase agreements outstanding used to fund acquisitions of investment securities with a weighted average interest rate of 2.17% and a weighted average remaining days-to-maturity of 55 days, compared $75.7 billion , 2.79% and 49 days, respectively, as of December 31, 2018 .

To limit our counterparty exposure, we diversify our funding across multiple counterparties and by counterparty region.

As of December 31, 2019 , we had master repurchase agreements with 46 financial institutions located throughout North America, Europe and Asia, including counterparties accessed through our wholly-owned captive broker-dealer subsidiary, BES .

BES has direct access to bilateral and triparty funding, including the General Collateral Finance Repo service offered by the Fixed Income Clearing Corporation, or "FICC," which provides us greater depth and diversity of funding at favorable terms relative to traditional bilateral repurchase agreement funding.

As of December 31, 2019 , $35.5 billion of our repurchase agreement funding was sourced through BES.

The table below includes a summary of our Agency RMBS repurchase agreement funding by number of repo counterparties and counterparty region as of December 31, 2019 .

Amounts available to be borrowed under our repurchase agreements are dependent upon lender collateral requirements and the lender's determination of the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates, credit quality and liquidity conditions within the investment banking, mortgage finance and real estate industries.

In addition, our counterparties apply a "haircut" to our pledged collateral, which means our collateral is valued at slightly less than market value.

This haircut reflects the underlying risk of the specific collateral and protects our counterparty against a change in its value, but conversely subjects us to counterparty credit risk and limits the amount we can borrow against our investment securities.

Our master repurchase agreements do not specify the haircut;

rather haircuts are determined on an individual repurchase transaction basis.

Throughout fiscal year 2019 , haircuts on our pledged collateral remained stable and, as of December 31, 2019 , our weighted average haircut was approximately 4.4% of the value of our collateral, inclusive of collateral funded through BES.

As of December 31, 2019 , our maximum amount at risk (or the excess of the value of collateral pledged over our repurchase liabilities) with any counterparty related to our repurchase agreements, excluding the FICC, was less than 4% of our tangible stockholders' equity, with our top five repo counterparties, excluding the FICC, representing less than 12% of our tangible stockholders' equity.

As of December 31, 2020 and 2019, 46% and 38%, respectively, of our repurchase agreement funding was through the GCF Repo service.

Our primary financing sources are collateralized borrowings structured as repurchase agreements.

We enter into repurchase agreements, or "repo," through bi-lateral arrangements with financial institutions and independent dealers.

We also enter into third-party repurchase agreements through our wholly-owned registered broker-dealer subsidiary, Bethesda Securities, LLC, such as tri-party repo offered through the FICC's GCF Repo service.

We manage our repurchase agreement funding position through a variety of methods, including diversification of counterparties, maintaining a staggered maturity profile and utilization of interest rate hedging strategies.

We also use TBA dollar roll transactions as a means of synthetically financing Agency RMBS.

The terms and conditions of our repurchase agreements are determined on a transaction-by-transaction basis when each such borrowing is initiated or renewed and, in the case of GCF Repo, by the variable margin requirements calculated by the FICC, which acts as the central counterparty.

The amount borrowed is generally equal to the fair value of the securities pledged, as determined by the lending counterparty, less an agreed-upon discount, referred to as a "haircut," which reflects the underlying risk of the specific collateral and protects the counterparty against a change in its value.

Interest rates are generally fixed based on prevailing rates corresponding to the term of the borrowing.

None of our repo counterparties are obligated to renew or otherwise enter into new borrowings at the conclusion of our existing borrowings.

The use of TBA dollar roll transactions increases our funding diversification, expands our available pool of assets, and increases our overall liquidity position, as TBA contracts typically have lower implied haircuts relative to Agency RMBS pools funded with repo financing.

However, if it were to become uneconomical to roll our TBA contracts into future months it may be necessary to take physical delivery of the underlying securities and fund those assets with cash or other financing sources, which could reduce our liquidity position.

Collateral Requirements and Unencumbered Assets

Amounts available to be borrowed under our repurchase agreements are dependent upon prevailing interest rates, the lender’s "haircut" requirements and collateral value.

Each of these elements may fluctuate with changes in interest rates, credit quality and liquidity conditions within the financial markets.

To help manage the adverse impact of interest rate changes on our borrowings, we utilize an interest rate risk management strategy involving the use of derivative financial instruments.

In particular, we attempt to mitigate the risk of the cost of our short-term funding liabilities increasing at a faster rate than the earnings of our long-term fixed rate assets during a period of rising interest rates.

The collateral requirements, or haircut levels, under our repo agreements are typically determined on an individual transaction basis or by the prevailing requirements established by the FICC for GCF tri-party repo.

Consequently, haircut levels and minimum margin requirements can change over time and may increase during periods of elevated market volatility.

If the fair value of our collateral declines, our counterparties will typically require that we post additional collateral to re-establish the agreed-upon collateral levels, referred to as "margin calls." Similarly, if the estimated fair value of our investment securities increases, we may request that counterparties release collateral back to us.

Our counterparties typically have the sole discretion to determine the value of pledged collateral but are required to act in good faith in making determinations of value.

Our agreements generally provide that in the event of a margin call, collateral must be posted on the same business day, subject to notice requirements.

As of December 31, 2020, we had met all our margin requirements.

The value of Agency RMBS collateral is impacted by market factors and is reduced by monthly principal pay-downs on the underlying mortgage pools.

Fannie Mae and Freddie Mac publish monthly security pay-down factors for their mortgage pools on the fifth day after month-end, but do not remit payment to security holders until generally the 25th day after month-end.

Bi-lateral repo counterparties assess margin to account for the reduction in value of Agency collateral when factors are released.

The FICC assesses margin on the last day of each month, prior to the factor release date, based on its internally projected pay-down rates (referred to as the "blackout period exposure adjustment" or "blackout margin").

On the factor release date, the blackout margin is released and collateralization requirements are adjusted to actual factor data.

Due to the timing difference between associated margin calls and our receipt of principal pay-downs, our liquidity is temporarily reduced each month for principal repayments.

We attempt to manage the liquidity risk associated with principal pay-downs by monitoring conditions impacting prepayment rates and through asset selection.

As of December 31, 2020, our portfolio largely consisted of lower coupon 30 and 15-year TBA securities, which are not subject to monthly principal pay-downs, and higher coupon holdings concentrated in high quality, specified Agency RMBS pools, which have a lower risk of prepayment than similar coupon generic Agency RMBS.

Collateral requirements under our derivative agreements are subject to our counterparties' assessment of their maximum risk of loss associated with the derivative instrument measured over a certain period of time, referred to as the initial or minimum margin requirement.

We are also subject to daily variation margin requirements based on changes in the value of the derivative instrument and/or collateral pledged.

Daily variation margin requirements also entitle us to receive collateral if the value of amounts owed to us under the derivative agreement exceeds the minimum margin requirement.

The collateral requirements under our TBA contracts are governed by the Mortgage-Backed Securities Division ("MBSD") of the FICC and, if applicable, by our third-party brokerage agreements, which may establish margin levels in excess of the MBSD.

Collateral levels for interest rate derivative agreements are typically governed by the central clearing exchange and the associated futures commission merchants ("FCMs"), which may establish margin levels in excess of the clearing exchange.

Collateral levels for interest rate derivative agreements not subject to central clearing are established by the counterparty financial institution.

Haircut levels and minimum margin requirements imposed by our counterparties reduce the amount of our unencumbered assets and limit the amount we can borrow against our investment securities.

During fiscal year 2020, haircuts on Agency RMBS collateral remained stable.

Haircuts and funding levels for our less liquid, credit-oriented securities were adversely impacted by the dislocation in the financial markets in the first quarter, but subsequently rebounded to levels consistent with historical norms.

As of December 31, 2020, the weighted average haircut on our repurchase agreements was approximately 4.6% of the value of our collateral, largely unchanged from December 31, 2019.

To mitigate the risk of future margins calls, we seek to maintain excess liquidity by holding unencumbered liquid assets that can be used to satisfy collateral requirements, collateralize additional borrowings or sold for cash.

As of December 31, 2020, our unencumbered assets totaled 60% of our tangible net equity, compared to 54% as of December 31, 2019.

The majority of our liquidity is held at AGNC, but we also maintain capital and excess liquidity at Bethesda Securities to meet regulatory standards, satisfy counterparty and clearing organization expectations, and for risk management purposes.

As of December 31, 2020, we had cash and unencumbered Agency RMBS totaling $5.4 billion, which excludes unencumbered CRT securities, non-Agency securities and assets held at Bethesda Securities.

Counterparty Risk

Collateral requirements imposed by counterparties subject us to the risk that the counterparty does not return pledged assets to us as and when required.

We attempt to manage this risk by monitoring our collateral positions and limiting our counterparties to registered clearinghouses and major financial institutions with acceptable credit ratings.

We also diversify our funding across multiple counterparties and by region.

As of December 31, 2020, our maximum amount at risk (or the excess value of collateral pledged over our repurchase liabilities) with any of our repurchase agreement counterparties, excluding the FICC, was less than 2% of our tangible stockholders' equity, with our top five repo counterparties, excluding the FICC, representing less than 6% of our tangible stockholders' equity.

As of December 31, 2020, approximately 9% of our tangible stockholder's equity was at risk with the FICC.

We could be exposed to credit risk if the FICC or an FICC netting member defaults on its obligations.

However, we believe that the risk is minimal due to the FICC's initial and daily mark-to-market margin requirements, guarantee funds and other resources that are available in the event of a default.

We may be required to pledge additional assets to our counterparties in the event the estimated fair value of the existing collateral pledged under our agreements declines and our counterparties demand additional collateral (a "margin call"), which may take the form of additional securities or cash.

Specifically, margin calls would result from a decline in the fair value of our investment securities securing our repurchase agreements as well as due to prepayments on the mortgages securing such securities.

Similarly, if the estimated fair value of our investment securities increases due to changes in interest rates or other factors, counterparties may release collateral back to us.

Our repurchase agreements generally provide that the valuations of securities securing our repurchase agreements are to be obtained from a generally recognized source agreed to by the parties.

In certain circumstances, however, our lenders have the sole discretion to determine the value of pledged collateral.

In such instances, our lenders are required to act in good faith in making determinations of value.

Our repurchase agreements generally provide that in the event of a margin call, we must provide additional securities or cash on the same business day that a margin call is made if the lender provides us notice prior to the margin notice deadline on such day.

As of December 31, 2019 , we had met all of our margin requirements and we had unrestricted cash and cash equivalents of $0.8 billion and unpledged securities of approximately $4.8 billion , including securities pledged to us and unpledged interests in our consolidated VIEs, available to meet margin calls on our repurchase agreements and other funding liabilities, derivative instruments and for other corporate purposes.

Although we believe we will have adequate sources of liquidity available to us through repurchase agreement financing to execute our business strategy, there can be no assurances that repurchase agreement financing will be available to us upon the maturity of our current repurchase agreements to allow us to renew or replace our repurchase agreement financing on favorable terms or at all.

If our repurchase agreement lenders default on their obligations to resell the underlying collateral back to us at the end of the term, we could incur a loss equal to the difference between the value of the collateral and the cash we originally received.

To help manage the adverse impact of interest rate changes on the value of our investment portfolio as well as our cash flows, we utilize an interest rate risk management strategy under which we use derivative financial instruments.

In particular, we attempt to mitigate the risk of the cost of our variable rate liabilities increasing at a faster rate than the earnings of our long-term fixed rate assets during a period of rising interest rates.

The primary derivative instruments that we use are interest rate swaps, interest rate swaptions, U.S.

Treasury securities and U.S.

Treasury futures contracts.

Please refer to Notes 2 and 5 to our Consolidated Financial Statements in this Form 10-K for further details regarding our use of derivative instruments.

As with repurchase agreements, our derivative agreements typically require that we pledge/receive collateral to/from our counterparties.

Our counterparties, or the central clearing agency, typically have the sole discretion to determine the value of the derivative instruments and the value of the collateral securing such instruments.

In the event of a margin call, we must provide additional collateral generally on the same or next business day.

We minimize counterparty credit risk associated with our derivative instruments by limiting our counterparties to registered central clearing exchanges and major financial institutions with acceptable credit ratings and by monitoring positions with individual counterparties.

Excluding centrally cleared derivative instruments, as of December 31, 2019 , our amount at risk with any counterparty related to our interest rate swap and swaption agreements was less than 1% of our stockholders' equity.

In the case of centrally cleared derivative instruments, we could be exposed to credit risk if the exchange or a central clearing member defaults on its obligations.

However, we believe that the risk is minimal due to initial and daily mark-to-market margin requirements, guarantee funds and other resources that are available in the event of a default.

TBA Dollar Roll Transactions

TBA dollar roll transactions used to finance the purchase of Agency RMBS represent a form of off-balance sheet financing accounted for as derivative instruments.

(See Notes 2 and 5 to our Consolidated Financial Statements in this Form 10-K additional details on of our TBA transactions).

Under certain market conditions, it may be uneconomical for us to roll our TBA contracts into future months and we may need to take or make physical delivery of the underlying securities.

If we were required to take physical delivery to settle a long TBA contract, we would have to fund our total purchase commitment with cash or other financing sources and our liquidity position could be negatively impacted.

As of December 31, 2019 , we had a net long TBA position with a total market value of $7.4 billion and a net carrying value of $25 million recognized in derivative assets/(liabilities), at fair value, on our Consolidated Balance Sheets in this Form 10-K .

Our TBA dollar roll contracts are also subject to margin requirements governed by the MBSD of the FICC and by our prime brokerage agreements, which may establish margin levels in excess of the MBSD.

Such provisions require that we establish an initial margin based on the notional value of the TBA contract, which is subject to increase if the estimated fair value of our TBA contract or the estimated fair value of our pledged collateral declines.

The MBSD has the sole discretion to determine the value of our TBA contracts and of the pledged collateral securing such contracts.

In the event of a margin call, we must generally provide additional collateral on the same business day.

Settlement of our TBA obligations by taking delivery of the underlying securities as well as satisfying margin requirements could negatively impact our liquidity position.

However, since we do not use TBA dollar roll transactions as our primary source of financing, we believe that we will have adequate sources of liquidity to meet such obligations.

Bethesda Securities Regulatory Capital Requirements

BES is subject to regulations of the securities business that include but are not limited to trade practices, capital structure, recordkeeping and conduct of directors, officers and employees.

As a self-clearing registered broker-dealer, BES is required to maintain minimum net regulatory capital as defined by SEC Rule 15c3-1 (the "Rule").

As of December 31, 2019 , the minimum net capital required was $0.3 million and BES had excess net capital of $621.7 million .

Regulatory capital in excess of the minimum required by the Rule is held to meet levels required by clearing organizations, the clearing bank and other repo counterparties.

Asset Sales and TBA Eligible Securities

We maintain a portfolio of highly liquid mortgage-backed securities.

We may sell our Agency securities through the TBA market by delivering them into TBA contracts, subject to "good delivery" provisions promulgated by SIFMA .

We may alternatively sell Agency securities that have more unique attributes on a specified basis when such securities trade at a premium over generic TBA securities or if the securities are not otherwise eligible for TBA delivery.

Since the TBA market is the second most liquid market (after the U.S.

Treasury market), maintaining a significant level of Agency securities eligible for TBA delivery enhances our liquidity profile and provides price support for our TBA eligible securities at or above generic TBA prices.

As of December 31, 2019 , approximately 95% of our fixed rate Agency RMBS portfolio was eligible for TBA delivery.

Equity Capital

To the extent we raise additional equity capital, we may use cash proceeds from such transactions to purchase additional investment securities, to make scheduled payments of principal and interest on our funding liabilities and/or for other general corporate purposes.

There can be no assurance, however, that we will be able to raise additional equity capital at any particular time or on any particular terms.

Excluding central clearing exchanges, as of December 31, 2020, our amount at risk with any counterparty to our derivative agreements was less than 1% of our stockholders' equity.

Agency RMBS securities are among the most liquid fixed income securities, and the TBA market is the second most liquid market (after the U.S.

Treasury market).

The vitality of these markets enables us to sell assets under most market conditions to generate liquidity through direct sales or delivery into TBA contracts, subject to "good delivery" provisions promulgated by the Securities Industry and Financial Markets Association ("SIFMA").

Under certain market conditions, however, we may be unable to realize the full "pay-up" value of our specified pool securities, or premium relative to generic Agency RMBS.

We attempt to manage this risk by maintaining a minimum level of securities that trade at or near TBA values that in our estimation enhances our portfolio liquidity across a wide range of market conditions.

Capital Markets

The equity capital markets serve as a source of capital to grow our business and to meet potential liquidity needs of our business.

The availability of equity capital is dependent on market conditions and investor demand for our common and preferred stock.

We will typically not issue common stock when the price of our common stock trades below our tangible net book value or issue preferred equity when its cost exceeds acceptable hurdle rates of return on our equity.

There can be no assurance that we will be able to raise additional equity capital at any particular time or on any particular terms.

Furthermore, when the trading price of our common stock is less than our estimate of our current tangible net book value per common share, among other conditions, we may repurchase shares of our common stock.
