Q1 2013 Results

Taxable REIT Income and Core Income

Estimated taxable REIT income for the quarter ended March 31, 2013, was
approximately $86.0million. The weighted average paid-in capital for the
quarter endedMarch31,2013, was $2.5 billion. The estimated taxable REIT
income represents an annualized return on weighted average paid-in capital for
the quarter of 13.8%. The Company distributes dividends based on its estimate
of taxable earnings, not based on earnings calculated in accordance with
Generally Accepted Accounting Principles (GAAP). Taxable REIT income and GAAP
earnings will differ primarily because of the non-taxable unrealizedchanges
in the value ofthe Company's derivatives, which the company uses as hedges.
These unrealized gains/losses are included in GAAP earnings, whereas
unrealized valuation changes are not included in taxable income.

Core Income for the quarter endedMarch 31, 2013, was $67.5million. "Core
Income" represents a non-GAAP measure and is defined as net income excluding
impairment losses, gains or losses on sales of securities and early
termination of derivatives, unrealized gains or losses on derivatives and
certain non-recurring expenses.CoreIncome may differ from GAAP earnings as
GAAP earnings include the unrealized gains or losses of the Company's
derivative instruments and the gains or losses on Agency Securities.

GAAPEarnings

For the purposes of computing GAAP net income, the change in fair value of the
Company's derivatives is reflected in current period net income, while the
change in fair value of its Agency Securities is reflected in its consolidated
statement of comprehensive income. Due to the rise in interest rates during
the quarter, the corresponding unrealized gain on derivatives was
$16.3million. GAAP net income for the first quarter of 2013 was
$102.3million, including realized gains on the sales of Agency Securities of
$18.5 million.

Dividends

The Company paid dividends of $0.08 per Common share of record for each month
of the quarter, resulting in payments to common stockholders of $79.8 million.
The Company also paid monthly dividends of $0.17 per outstanding share of

stockholders of $1.1 million. For the quarter ended March 31, 2013, the
Company paid initial dividends of $0.25 per outstanding share of Series B
Preferred Stock, resulting in payments to Series B Preferred stockholders of
$1.4 million. The Company had estimated taxable REIT income available to pay
dividends of $86.0 million in Q1 2013.

Per Share Amounts

Per Common share amounts are net of applicable Preferred Stock dividends and
liquidation preferences.The denominators used to calculate per Common share
amounts as of March 31, 2013 and for the quarter then ended reflect the
dilutive effects of unvested stock awards.Such effects are not material.

(including realized cost of hedges) was 0.98%, resulting in a net interest
spread of 1.35% for the quarter.

Regulation G Reconciliation

Taxable REIT income is calculated according to the requirements of the
Internal Revenue Coderather than GAAP. ARMOUR plans to distribute at least
90% of its taxable REIT incomein order to maintain its tax qualification as a
REIT. ARMOUR believes that taxable REIT income is useful to investors because
taxable REIT income is directly related to the amount of dividends the Company
is required to distribute in order to maintain its REIT tax qualification
status. Core income also excludes gains and losses on security sales.However,
because taxable REIT income and Core income are incomplete measures of the
Company's financial performance and involve differences from net income
computed in accordance with GAAP, taxable REIT income and Core income should
be considered as supplementary to, and not as a substitute for, ARMOUR's net
income computed in accordance with GAAP as a measure of the Company's
financial performance.

The following table reconciles ARMOUR's consolidated results from operations
to taxable REIT income and Core income for the quarter ended March 31, 2013:
