Securities Portfolio Overview
Securities Portfolio Overview
Sonabank owns a portfolio of trust preferred securities. These securities have been adversely
affected by the continued deterioration of some sectors of the banking system which have resulted
in increased deferrals and defaults in the underlying collateral. 
In performing a detailed cash flow analysis of each security, Sonabank works with independent
third parties to identify its best estimate of the cash flow estimated to be collected. If this estimate
results in a present value of expected cash flows that is less than the amortized cost basis of a
security (that is, credit loss exists), an OTTI is considered to have occurred. If there is no credit
loss, any impairment is considered temporary. The cash flow analysis performed by Sonabank
included the following assumptions:
  Assume that all of the issuers rated 1 by IDC Financial Publishing that have not already defaulted or deferred will
default or defer immediately with 100% loss, except for one issuer that has received TARP funding. On one
security, TPREF Funding II which has a minimal cushion, Sonabank assumed an additional $10 million in defaults
which results in an OTTI. 
  Assume that annual defaults for the remaining life of each security will be 37.5 basis points. According to FTN
Financial: “The FDIC lists the number of bank failures each year from 1934-2008. Comparing bank failures to the
number of FDIC institutions produces an annual average default rate of 36 basis points.”
  Assume recoveries ranging from 0% to 75% on deferrals after two years depending on the IDC rating of the
deferring entity.
  Assume no prepayments for 10 years and then 1% per annum for the remaining life of the security. According to
FTN Financial: “Prepayments were common in 2006 and 2007 when issuers were able to refinance into lower cost
borrowings. That was a much different environment than today and most parties expect prepayments to be very
low absent a change in credit conditions.” 
  Securities have been modeled using the above assumptions by Sandler O’Neill or Sterne Agee using the forward
LIBOR curve plus original spread to discount projected cash flows to present values.

Southern National Bancorp of Virginia
At the end of the second quarter of 2009, management’s analysis deemed three of the ten securities owned were other than
temporarily impaired. The cash flow analysis in the second quarter indicated that one security, ALESCO XV C1 would
probably experience significant credit losses. Two others, ALESCO V C1 and ALESCO XVI C, would probably
experience minor credit losses. Southern National booked second quarter OTTI charges accordingly. In the third quarter
of 2009 analysis indicated that Southern National would incur OTTI charges on three additional securities: MMC Funding
XVIII,
TRAP
2007
XIII
D
and
TPREF
Funding
II
and
additional
OTTI
charges
on

other
securities:

Subsequent
to
the
Initial
Report
of
the
Company’s
3
quarter
earnings
on
October
20,
2009,
the
Company learned of additional deferrals made in the fourth quarter of 2009 on three of the trust
preferred securities it owns.
The deferral on one of the trust preferred securities resulted in an
additional other than temporary impairment charge of approximately $191,000 pre-tax ($126,000
after
tax)
for
the
three
months
ended
September
30,
2009,
and
an
aggregate
other
than
temporary
impairment charge of $1.2 million for the quarter.  Recently issued accounting standards (ASC
855-10) require the Company to consider events occurring after the reporting period up until the
time its financial statements are issued.  If such events provide evidence about a condition that
existed at the reporting period, it should be recorded in that period. Southern National evaluated
these new deferrals and determined that the additional charges should be recorded as of September
30, 2009 in accordance with this standard.
