monitor an entity’s solvency.
This calculation indicates recommended minimum levels of required capital and surplus and signals regulatory measures should actual surplus fall below these recommended levels.
If RBC were adopted by all states at December 31, 2004, each of our subsidiaries would be in compliance and we would have $405.6 million of aggregate capital and surplus above any of the levels that require corrective action under RBC.
Contractual Obligations We are contractually obligated to make payments for years subsequent to December 31, 2004 as follows:
## Table 0 ##
(1) Debt includes $294 million of borrowings under the Credit Agreement which matures on September 28, 2009 related to the February 16, 2005 CarePlus acquisition.
Debt payments could be accelerated upon violation of debt covenants.
We believe the likelihood of debt covenant violation is remote.
(2) Interest includes the estimated contractual interest payments under our debt agreements net of the effect of the associated swapagreements assuming no change in the variable LIBOR rate as of December 31, 2004.
(3) We lease facilities, computer hardware, and other equipment under long-term operating leases that are noncancelable and expire on various dates through 2017.
We sublease facilities or partial facilities to third party tenants for space not used in our operations which partially mitigates our operating lease commitments.
An operating lease, accounted for under the provisions of Statement of Financial Accounting Standards No.13, Accounting for Leases, is a type of off-balance sheet arrangement.
Assuming we acquired the asset, rather than leased, we would have recognized a liability for the financing of these assets.
See also Note 14 to the consolidated financial statements.
(4) Purchase and other obligations include agreements to purchase services, primarily information technology related services, or to make improvements to real estate that are enforceable and legally binding on us and that specify all significant terms, including: fixed or minimum levels of service to be purchased; fixed, minimum or variable price provisions; and the appropriate timing of the transaction.
Purchase obligations exclude agreements that are cancelable without penalty.
Indemnifications and Guarantees Our operating lease of an airplane, which expires January 1, 2010, provides for a residual value payment of no more than $4.8 million at the end of the lease term.
At the end of the term we have the right to exercise a purchase option or the airplane can be sold to a third party.
If we decide not to exercise our purchase option, we must pay the lessor a maximum amount of $4.8 million.
This amount will be reduced by the net sales proceeds in excess of $4.2 million from the sale of the airplane to a third party.
Through indemnity agreements approved by the state regulatory authorities, certain of our regulated subsidiaries generally are guaranteed by Humana Inc. , our parent company, in the event of insolvency for (1), member coverage for which premium payment has been made prior to insolvency; (2), benefits for members then hospitalized until discharged; and (3), payment to providers for services rendered prior to insolvency.
Our parent also has guaranteed the obligations of our TRICARE subsidiaries.
In the ordinary course of business, we enter into contractual arrangements under which we may agree to indemnify a third party to such arrangement from any losses incurred relating to the services they perform on behalf of us, or for losses arising from certain events as defined within the particular contract, which may
calculate the risk adjusted premium payment to us.
We collect, capture and submit the necessary diagnosis data to CMS weekly.
We estimate risk adjustment revenues based upon the diagnosis data we submitted to CMS.
This also resulted in a corresponding increase in the capitation payable to physicians under risk sharing arrangements discussed below.
The detail of medical and other expenses payable was as follows at December 31, 2005, 2004 and 2003:
## Table 1 ##
(1) IBNR represents an estimate of medical expenses payable for claims incurred but not reported (IBNR) at the balance sheet date.
The level of IBNR is primarily impacted by membership levels, medical claim trends and the receipt cycle time, which represents the length of time between when a claim is initially incurred and when the claim form is received (i. e.  a shorter time span results in a lower IBNR).
(2) Reported claims in process represents the estimated valuation of processed claims that are in the post claim adjudication process, which consists of administrative functions such as audit and check batching and handling.
(3) Other medical expenses payable includes capitation and pharmacy payables.
The balance due to our pharmacy benefit administrator fluctuates due to bi-weekly payments and the month-end cutoff.
Medical and other expenses payable primarily increased during 2005 due to (1) growth in Medicare membership, (2) medical claims inflation, (3) the transition to the new South region contract, (4) an increase in the TRICARE payable resulting from an increase in claims inventory at our third party claims processing vendor as discussed under the total net receivables table on the previous page, and (5) an increase in the capitation payable to physicians under risk sharing arrangements.
Medical and other expenses payable increased during 2004 due primarily to medical claims inflation.
Cash Flow from Investing Activities During 2005, we paid $352.8 million to acquire CarePlus, net of $92.1 million of cash acquired, and we paid $50.0 million to acquire Corphealth, net of $4.0 million of cash acquired.
During 2004, we paid $141.8 million to acquire Ochsner, net of $15.3 million of cash acquired.
We reinvested a portion of our operating cash flows over the last several years in investment securities, primarily short-duration fixed income securities, totaling $233.3 million in 2005, $407.3 million in 2004, and $283.1 million in 2003.
Our ongoing capital expenditures primarily relate to our technology initiatives and administrative facilities necessary for activities such as claims processing, billing and collections, medical utilization review, and customer service.
Total capital expenditures, excluding acquisitions, were $165.8 million in 2005, $114.1 million in 2004, and $101.3 million in 2003.
The increased spending in 2005 primarily resulted from our Medicare expansion initiatives.
Excluding acquisitions, we expect our total capital expenditures in 2006 to range between $125 million and $135 million.
Despite significant growth in Medicare, Medicare receivables declined $6.5 million from 2006 to 2007 due to the net collection of receivables associated with the CMS risk adjustment model.
Likewise, the $77.3 million increase in Medicare receivables from 2005 to 2006 resulted from an increase in receivables associated with the CMS risk adjustment model.
The decline in Commercial and other receivables from 2005 to 2006 resulted from the change in the mix of members from fully-insured to ASO.
The $22.7 million increase in the allowance for doubtful accounts from 2006 to 2007 resulted from the growth of the Medicare business.
The detail of benefits payable was as follows at December 31, 2007, 2006 and 2005:
## Table 2 ##
(1) IBNR represents an estimate of benefits payable for claims incurred but not reported (IBNR) at the balance sheet date.
The level of IBNR is primarily impacted by membership levels, medical claim trends and the receipt cycle time, which represents the length of time between when a claim is initially incurred and when the claim form is received (i. e.  a shorter time span results in a lower IBNR).
(2) Military services benefits payable primarily results from the timing of the cost of providing health care services to beneficiaries and the related reimbursement by the federal government as more fully described in Note 2 to the consolidated financial statements included in Item 8.
—Financial Statements and Supplementary Data.
A corresponding receivable is included in the base receivable in the previous receivables table.
(3) Reported claims in process represents the estimated valuation of processed claims that are in the post claim adjudication process, which consists of administrative functions such as audit and check batching and handling.
(4) Other benefits payable includes capitation and pharmacy payables.
The balance due to our pharmacy benefit administrator fluctuates due to bi-weekly payments and the month-end cutoff.
Benefits payable increased during 2007 and 2006 primarily due to growth in Medicare membership and to a lesser extent medical claims inflation.
Cash Flow from Investing Activities We reinvested a portion of our operating cash flows over the last several years in investment securities, primarily short-duration fixed income securities, totaling $430.1 million in 2007, $862.1 million in 2006, and $233.3 million in 2005.
Our ongoing capital expenditures primarily relate to our information technology initiatives and administrative facilities necessary for activities such as claims processing, billing and collections, medical utilization review, and customer service.
Total capital expenditures, excluding acquisitions, were $239.2 million in 2007, $193.2 million in 2006, and $165.8 million in 2005.
The increased spending in 2007 primarily resulted from the
Table of Contents Stock Total Return Performance The following graph compares our total return to stockholders with the returns of the Standard & Poor’s Composite 500 Index (“S&P 500”) and the Dow Jones US Select Health Care Providers Index (“Peer Group”) for the five years ended December 31, 2014.
The graph assumes an investment of $100 in each of our common stock, the S&P 500, and the Peer Group on December 31, 2009, and that dividends were reinvested when paid.
