The assets and liabilities of these consolidated joint ventures were immaterial at March 27, 2016 and September 27, 2015.

Cash and cash equivalents maintained by the consolidated joint ventures at March 27, 2016 and September 27, 2015 were $1.4 million and $0.7 million, respectively. Unconsolidated Joint Ventures We account for our unconsolidated joint ventures using the equity method of accounting. Under this method, we recognize our proportionate share of the net earnings of these joint ventures within “Other costs of revenue” in our condensed consolidated statements of income. For the three and six months ended March 27, 2016, we reported $0.7 million and $0.9 million of equity in earnings of unconsolidated joint ventures, respectively, compared to $1.2 million and $1.8 million for the same periods last year. Our maximum exposure to loss as a result of our investments in unconsolidated joint ventures is typically limited to the aggregate of the carrying value of the investment. Future funding commitments for our unconsolidated joint ventures are immaterial. The unconsolidated joint ventures are, individually and in the aggregate, immaterial to our condensed consolidated financial statements. The aggregate carrying values of the assets and liabilities of the unconsolidated joint ventures were $15.7 million and $13.7 million, respectively, at March 27, 2016, and $17.1 million and $15.2 million, respectively, at September 27, 2015.
