We are involved in various claims and litigation arising principally in the ordinary course of business. We believe that adequate provision for resolution of all current claims and pending litigation has been made and that the disposition of these matters will not have a material adverse effect on our results of operations and liquidity or on our financial condition.

In March 2018, the Pennsylvania Attorney General informed the Company that it was conducting a review of our construction of stucco homes in Pennsylvania after January 1, 2005 and requested that we voluntarily produce documents and information. The Company has produced documents and information in response to this request. Management cannot at this time predict the eventual scope or outcome of this matter.

Generally, our agreements to acquire land parcels do not require us to purchase those land parcels, although we, in some cases, forfeit any deposit balance outstanding if and when we terminate an agreement.

In addition, we expect to purchase approximately 2,600 additional home sites over a number of years from several joint ventures in which we have interests; the purchase prices of these home sites will be determined at a future date.

At January 31, 2019, we also had purchase commitments to acquire land for apartment developments of approximately $274.2 million, of which we had outstanding deposits in the amount of $10.5 million. We intend to develop these projects in joint ventures with unrelated parties in the future.

We have additional land parcels under option that have been excluded from the aggregate purchase commitments since we do not believe that we will complete the purchase of these land parcels and no additional funds will be required from us to terminate these contracts.

At January 31, 2019, we had investments in a number of unconsolidated entities, were committed to invest or advance additional funds, and had guaranteed a portion of the indebtedness and/or loan commitments of these entities. See Note 3, “Investments in Unconsolidated Entities,” for more information regarding our commitments to these entities.

At January 31, 2019, we had outstanding surety bonds amounting to $713.8 million, primarily related to our obligations to governmental entities to construct improvements in our communities. We estimate that approximately $330.7 million of work remains on these improvements. We have an additional $160.9 million of surety bonds outstanding that guarantee other obligations. We do not believe that it is probable that any outstanding bonds will be drawn upon.

At January 31, 2019, we had outstanding letters of credit of $174.4 million under our Credit Facility. These letters of credit were issued to secure various financial obligations, including insurance policy deductibles and other claims, land deposits, and security to complete improvements in communities in which we are operating. We do not believe that it is probable that any outstanding letters of credit will be drawn upon.

At January 31, 2019, we had agreements of sale outstanding to deliver 5,954 homes with an aggregate sales value of $5.37 billion.
