(a)Our money market funds are invested in high-yield secure and stable funds. The increase in 2019 is primarily due to proceeds from our May 2019 issuance of senior notes and our September 2019 issuance of Canadian senior notes. See Note 3 for additional information.
(b)Our available-for-sale securities generally mature over the next ten years.
(c)When available, Level 3 investments have been measured based on third-party investors’ recent or pending transactions in these securities, which are considered the best evidence of fair value. When this evidence is not available, we use other valuation techniques as appropriate and available. These valuation methodologies may include transactions in similar instruments, discounted cash flow techniques, third-party appraisals or industry multiples and public company comparable transactions. In the first quarter of 2019, we redeemed our preferred stock received in conjunction with the 2014 sale of our Puerto Rico operations for $17 million. At the time of redemption, the value of redeemable preferred stock was $20 million, resulting in a $3 million loss on investment.

Fair Value of Debt

As of September 30, 2019 and December 31, 2018, the carrying value of our debt was $13.4 billion and $10.0 billion, respectively. The estimated fair value of our debt was approximately $14.6 billion and $10.1 billion as of September 30, 2019 and December 31, 2018, respectively. The increase in the fair value of our debt in 2019 is primarily due to $3.1 billion of net borrowings (inclusive of net commercial paper repayments), which are discussed further in Note 3, and decreases in current market rates for similar types of instruments.  

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or holders of the instruments, could realize in a current market exchange. The use of different assumptions or estimation methodologies could have a material effect on the estimated fair values. The fair value estimates are based on Level 2 inputs of the fair value hierarchy available as of September 30, 2019 and December 31, 2018. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented.
