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. The resolution also authorizes the use of option exercise proceeds for the repurchase of our common stock. During the six months ended March 31, 2018, we repurchased approximately 17,000 common shares at a cost of $1.0 million. During the six months ended March 31, 2017, we acquired 0.6 million common shares at a cost of $28.9 million. At March 31, 2018, $108.8 million remained available for future stock repurchases.
Our deferred compensation plan assets include $16.3 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.
During the six months ended March 31, 2018, we granted 0.3 million RSUs to our employees. These awards will vest ratably over five years. During the three months ended March 31, 2018, we granted approximately 22,000 RSU's to members of our Board of Directors. These awards vest over one year.
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 amounts that are ready to be invoiced and the funds are collectible within standard invoice terms.
During the six months ended March 31, 2017, we undertook a restructuring of our United Kingdom Human Services operations as part of the ongoing integration of Remploy. During the six months ended March 31, 2017, we recorded restructuring costs of $2.2 million, principally severance expenses. During the three and six months ended March 31, 2018, we recorded additional restructuring costs of $2.3 million.
As part of our work for the U.S. Federal Government and many states, we allocate costs to individual projects and segments using a methodology driven by the Federal Cost Accounting Standards. During fiscal year 2018, we updated our methodology for allocation of costs which resulted in certain costs which had been within Cost of Revenue now being classified as Selling, General and Administrative Expenses (SG&A). If we had utilized the same methodology in fiscal year 2018 as we had in fiscal year 2017, we estimate that SG&A would have been lower by approximately $1.3 million and $2.5 million during the three and six months ended March 31, 2018, respectively. This change in methodology did not affect our operating income.
Securities Class Action Lawsuit
On August 4, 2017, the Company and certain officers were named as defendants in a putative class action lawsuit filed in the U.S. District Court for the Eastern District of Virginia, Steamfitters Local 449 Pension Plan v. MAXIMUS. The plaintiff alleges the defendants made a variety of materially false and misleading statements, or failed to disclose material information, concerning the status of the Company’s Health Assessment Advisory Services project for the U.K. Department for Work and Pensions from the period October 20, 2014 through February 3, 2016, and seeks damages to be proved at trial. We deny the allegations and intend to defend the matter vigorously. At this time, it is not possible to reasonably predict whether this matter will be permitted to proceed as a class or to reasonably estimate the value of the claims asserted and we are unable to estimate the potential loss or range of loss.
