Comparisons of our operating cash flows also are impacted by other changes in our working capital. The
most significant drivers of changes in our working capital are typically the timing of receipts for premiums and
ASO fees and payments of benefit expenses. We illustrate these changes with the following summaries of
receivables and benefits payable.
The detail of total net receivables was as follows at December 31, 2008, 2007 and 2006:

Military services base receivables consist of estimated claims owed from the federal government for health
care services provided to beneficiaries and underwriting fees. The claim reimbursement component of military
services base receivables is generally collected over a three to four month period. The timing of claim
reimbursements resulted in the increase in base receivables from 2007 to 2008 compared to a decrease from 2006
to 2007.
The changes in Medicare receivables over the last three years have been impacted by the growth in our
Medicare business and the timing of accruals and related collections associated with the CMS risk-adjustment
model.
The $37.3 million increase in Commercial and other receivables from 2007 to 2008 primarily was the result
of an increase in Puerto Rico Medicaid receivables, which were collected in January 2009.
