Asset-Backed Securities.
The Company’s asset-backed securities are diversified both by sector and by issuer.
At December 31, 2008, the largest exposures in the Company’s asset-backed securities portfolio were credit card receivables, automobile receivables, student loan receivables and residential mortgage-backed securities backed by sub-prime mortgage loans of 49%, 10%, 10% and 10% of the total holdings, respectively.
At December 31, 2008 and 2007, the Company’s holdings in asset-backed securities was $10.5 billion and $10.6 billion at estimated fair value.
At December 31, 2008 and 2007, $7.9 billion and $5.7 billion, respectively, or 75% and 54%, respectively, of total asset-backed securities were rated Aaa/AAA by Moody’s, S&P or Fitch.
The Company’s asset-backed securities included in the structured securities table above include exposure to residential mortgagebacked securities backed by sub-prime mortgage loans.
Sub-prime mortgage lending is the origination of residential mortgage loans to customers with weak credit profiles.
The Company’s exposure exists through investment in asset-backed securities which are supported by sub-prime mortgage loans.
The slowing U. S.  housing market, greater use of affordable mortgage products, and relaxed underwriting standards for some originators of below-prime loans have recently led to higher delinquency and loss rates, especially within the 2006 and 2007 vintage year.
Vintage year refers to the year of origination and not to the year of purchase.
These factors have caused a pull-back in market liquidity and repricing of risk, which has led to an increase in unrealized losses from December 31, 2007 to December 31, 2008.
Based upon the analysis of the Company’s exposure to sub-prime mortgage loans through its investment in asset-backed securities, the Company expects to receive payments in accordance with the contractual terms of the securities.
The following table shows the Company’s exposure to asset-backed securities supported by sub-prime mortgage loans by credit quality and by vintage year:

have access to liquidity by issuing bonds to public or private investors based on our assessment of the current condition of the credit markets.
At December 31, 2009, we had a working capital surplus of approximately $1.0 billion, which reflects our decision to maintain additional cash reserves to enhance liquidity in response to difficult economic conditions.
At December 31, 2008, we had a working capital deficit of approximately $100 million.
Historically, we have had a working capital deficit, which is common in our industry and does not indicate a lack of liquidity.
We maintain adequate resources and, when necessary, have access to capital to meet any daily and short-term cash requirements, and we have sufficient financial capacity to satisfy our current liabilities.
|Millions of Dollars|2009|2008|2007|
|Cash provided by operating activities|$3,234|$4,070|$3,277|
|Cash used in investing activities|-2,175|-2,764|-2,426|
|Cash used in financing activities|-458|-935|-800|
|Net change in cash and cash equivalents|$601|$371|$51|

Operating Activities Lower net income in 2009, a reduction of $184 million in the outstanding balance of our accounts receivable securitization program, higher pension contributions of $72 million, and changes to working capital combined to decrease cash provided by operating activities compared to 2008.
Higher net income and changes in working capital combined to increase cash provided by operating activities in 2008 compared to 2007.
In addition, accelerated tax deductions enacted in 2008 on certain new operating assets resulted in lower income tax payments in 2008 versus 2007.
Voluntary pension contributions in 2008 totaling $200 million and other pension contributions of $8 million partially offset the year-over-year increase versus 2007.
Investing Activities Lower capital investments and higher proceeds from asset sales drove the decrease in cash used in investing activities in 2009 versus 2008.
Increased capital investments and lower proceeds from asset sales drove the increase in cash used in investing activities in 2008 compared to 2007.

Question: In the year with largest amount of Fair Value for Aaa, what's the growing rate of Fair Value for Aa?

Solution:
def solution():
    # Define variables name and value
    Aa_fair_value_2007 = 383
    Aa_fair_value_2008 = 197

    # Do math calculation to get the answer
    answer = (Aa_fair_value_2008 - Aa_fair_value_2007) / Aa_fair_value_2007 * 100

    return answer
Answer: -48.56396866840731
