Issuer Purchases of Equity Securities The following table provides information about purchases by us during the three months ended December 31, 2013 of equity securities that are registered by us pursuant to Section 12 of the Exchange Act:
## Table 0 ##
(1) As announced on May 1, 2013, in April 2013, the Board of Directors replaced its previously approved share repurchase authorization of up to $1 billion with a current authorization for repurchases of up to $1 billion of our common shares exclusive of shares repurchased in connection with employee stock plans, expiring on June 30, 2015.
Under the current share repurchase authorization, shares may be purchased from time to time at prevailing prices in the open market, by block purchases, or in privately-negotiated transactions, subject to certain regulatory restrictions on volume, pricing, and timing.
As of February 1, 2014, the remaining authorized amount under the current authorization totaled approximately $580 million.
(2) Excludes 0.1 million shares repurchased in connection with employee stock plans.
Other Businesses Pretax loss for our Other Businesses of $18 million for 2012 compared to pretax income of $41 million for 2011.
The year-over-year decline primarily reflects the combined effect of costs in connection with a litigation settlement associated with our military services business in 2012, reserve strengthening for our closed block of long-term care insurance policies in 2012, and a change in profitability under the current TRICARE South Region contract in connection with our bid strategy.
Liquidity Our primary sources of cash include receipts of premiums, services revenue, and investment and other income, as well as proceeds from the sale or maturity of our investment securities and borrowings.
Our primary uses of cash include disbursements for claims payments, operating costs, interest on borrowings, taxes, purchases of investment securities, acquisitions, capital expenditures, repayments on borrowings, dividends, and share repurchases.
Because premiums generally are collected in advance of claim payments by a period of up to several months, our business normally should produce positive cash flows during periods of increasing premiums and enrollment.
Conversely, cash flows would be negatively impacted during periods of decreasing premiums and enrollment.
From period to period, our cash flows may also be affected by the timing of working capital items.
The use of operating cash flows may be limited by regulatory requirements which require, among other items, that our regulated subsidiaries maintain minimum levels of capital and seek approval before paying dividends from the subsidiaries to the parent.
Our use of operating cash flows derived from our non-insurance subsidiaries, such as in our Healthcare Services segment, is generally not restricted by Departments of Insurance.
For 2014, the effect of the commercial risk adjustment, risk corridor, and reinsurance provisions of the Health Care Reform Law will impact the timing of our operating cash flows, as we expect to build a receivable in 2014 that will be collected in 2015.
It is reasonably possible that the receivable could be material to our operating cash flow in 2014.
In 2014, we expect our operating cash flows to decline from 2013.
Any amounts receivable or payable associated with these risk limiting programs should not have a significant impact on subsidiary capital and surplus.
For additional information on our liquidity risk, please refer to Item 1A.
Risk Factors in this report.
Cash and cash equivalents decreased to $1.1 billion at December 31, 2013 from $1.3 billion at December 31, 2012.
The change in cash and cash equivalents for the years ended December 31, 2013, 2012 and 2011 is summarized as follows:
## Table 1 ##
Cash Flow from Operating Activities The change in operating cash flows over the three year period primarily results from the corresponding change in earnings, enrollment activity, and the timing of working capital items as discussed below.
Cash flows were positively impacted by annual Medicare enrollment gains because premiums generally are collected in advance of claim payments by a period of up to several months.
In addition, 2013 operating cash flows were impacted by increased marketing and distribution costs associated with higher sales during the annual election period for Medicare beneficiaries for 2014, investment spending for new state-based contracts and exchanges under the Health Care Reform Law, and higher Medicare Part D risk corridor payments related to settlements for prior years, including $158 million related to the 2011 contract year.
The detail of benefits payable was as follows at December 31, 2013, 2012 and 2011:
## 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) 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, as well as amounts owed to our pharmacy benefit administrator which fluctuate due to bi-weekly payments and the month-end cutoff.
(3) Military services benefits payable primarily represents the run-out of the claims liability associated with our previous TRICARE South Region contract that expired on March 31, 2012.
A corresponding receivable for reimbursement by the federal government is included in the military services receivable in the previous receivables table.
(4) Other benefits payable include amounts owed to providers under capitated and risk sharing arrangements.
The increase in benefits payable in 2013 primarily was due to an increase in the amount of processed but unpaid claims due to our pharmacy benefit administrator, which fluctuate due to month-end cutoff, and an increase in IBNR, primarily as a result of Medicare Advantage membership growth.
The increase in benefits payable in 2012 primarily was due to an increase in IBNR, primarily as a result of Medicare Advantage membership growth, partially offset by a $335 million decrease in the military services benefits payable due to the run-out of claims under the previous TRICARE South Region contract that expired on March 31, 2012, a decrease in amounts owed to providers under capitated and risk sharing arrangements, and a decrease in the amounts due to our pharmacy benefit administrator which fluctuate due to month-end cutoff.
Under the current TRICARE South Region contract effective April 1, 2012, the federal government retains the risk of the cost of health benefits and related benefit obligation as further described in Note 2 to the consolidated financial statements included in Item 8.
– Financial Statements and Supplementary Data.
The increase in benefits payable in 2011 primarily was due to an increase in processed but unpaid claims, including amounts due to our pharmacy benefit administrator, which fluctuate due to month-end cutoff, and an increase in military services benefits payable.
In addition to the timing of receipts for premiums and services fees and payments of benefits expense, other working capital items impacting operating cash flows primarily resulted from the timing of payments for the Medicare Part D risk corridor provisions of our contracts with CMS, changes in the timing of the collection of pharmacy rebates, and the timing of payments for premium rebates associated with minimum benefit ratios required under the Health Care Reform Law.
In 2014, our operating cash flows will also be impacted by the timing of payments and receipts associated with the commercial risk adjustment, risk corridor, and reinsurance provisions of the Health Care Reform Law as discussed above.
