During the three months ended December 31, 2015 and 2014, we made income tax payments of $19.2 million and $5.9 million, respectively.
At December 31, 2015, we held cash and cash equivalents of $51.0 million. Approximately $45.1 million of these funds are denominated in foreign currencies and held in jurisdictions outside the United States and we have no requirement or intent at this time to transfer the funds to the United States. Declines in the value of foreign currencies with respect to the United States Dollar, notably the Australian Dollar and British Pound, resulted in a decline in net assets of $2.2 million in the three months ended December 31, 2015, including a $0.6 million decline in our cash and cash equivalents balance and a $1.2 million decline in our goodwill balance. These declines were recorded as losses in our Statement of Comprehensive Income.
Under a resolution adopted in August 2015, the Board of Directors authorized the repurchase, at management's discretion, of up to an aggregate of $200 million of our common stock. This resolution superseded similar authorizations from November 2011 and June 2014. The resolution also authorizes the use of option exercise proceeds for the repurchase of our common stock. During the three months ended December 31, 2015 and 2014, we repurchased 0.5 million and 0.8 million common shares at a cost of $29.1 million and $30.6 million, respectively. At December 31, 2015, $139.4 million remained available for future stock repurchases.
Our deferred compensation plan assets include $10.3 million invested in mutual funds that have quoted prices in active markets. These assets are recorded at fair value with changes in fair value being recorded in the Statement of Operations.
In November 2015, we granted 0.4 million RSUs to our employees. These awards will vest ratably over five years.
The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and other amounts included within current assets and liabilities that meet the definition of a financial instrument are shown at values equivalent to fair value due to the short-term nature of these items. Our accounts receivable balance includes both amounts invoiced and those where amounts are ready to be invoiced and the funds are collectible within standard invoice terms.
